Hurricane Delta Brings Wind and Rain to Louisiana

Hurricane Delta brought wind and rain to Louisiana on Friday evening.  At 8:00 p.m. EDT on Friday the center of Hurricane Delta was located at latitude 30,0°N and longitude 93.0°W which put it about 25 miles west-southwest of Jennings, Louisiana.  Delta was moving toward the north-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 971 mb.

A Hurricane Warning was in effect for the portion of the coast from High Island, Texas to Morgan City, Louisiana.  Tropical Storm Warnings were in effect for the portions of the coast from San Luis Pass to High Island, Texas and from Morgan City, Louisiana to the Mouth of the Pearl River.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

According the National Hurricane Center the center of Hurricane Delta officially made landfall on the coast of Louisiana near Creole.  The maximum sustained wind speed at the time of landfall was 100 m.p.h. (160 km/h).  Winds to hurricane force extended out 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extended out 160 miles (260 km).

Hurricane Delta weakened on Friday while moved toward the coast of Louisiana.  An upper level trough produced southwesterly winds which blew toward the top of Delta.  Those winds caused moderate vertical wind shear.  The circulation around Hurricane Delta pulled drier air about the southern side of the hurricane.  In addition, Delta moved over cooler water near the coast of Louisiana.  The combination of shear, drier air and cooler water caused the circulation to weaken on Friday afternoon.

Even though it weakened, Hurricane Delta brought strong winds and rain to Louisiana.  A weather station in Lake Charles, Louisiana reported a sustained wind speed of 64 m.p.h. (103 km/h) and a wind gust of 95 m.p.h. (153 km/h).  A weather station at Lake Arthur, Louisiana reported a sustained wind speed of 77 m.p.h. (125 km/h) and a wind gust of 96 m.p.h. (154 km/h).  A weather station at Cameron, Louisiana reported a sustained wind speed of 58 m.p.h. (93 km/h) and a wind gust of 78 m.p.h. (128 km/h).  A weather station at Port Arthur, Texas reported a wind gust of 71 m.p.h. (114 km/h).

Winds blowing around the eastern side of Hurricane Delta pushed water toward the coast and cause a storm surge.  A station at Freshwater Canal Locks in Louisiana reported a water level rise of 8 feet (2.4 meters).  Delta also dropped heavy rain over parts of Louisiana.  Flash Flood Warnings were issued for some of the areas around Lake Charles and Lafayette, Louisiana.

Hurricane Delta will weaken steadily as it moves farther inland.  The upper level trough will steer Delta toward the northeast during the next several days.  On its anticipated track Delta will move across Louisiana toward southwest Tennessee.  The center of Delta will pass near Alexandria and Monroe, Louisiana.  Flash Flood Watches were in effect for Louisiana, northern Mississippi. southeastern Arkansas, and southwestern Tennessee.

Hurricane Delta Nears Louisiana

Hurricane Delta neared the coast of Louisiana on Friday morning.  At 11:00 a.m. EDT on Friday the center of Hurricane Delta was located at latitude 28.0°N and longitude 93.8°W which put it about 130 miles (215 km) south of Cameron, Louisiana.  Delta was moving toward the north at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (220 km/h).  The minimum surface pressure was 962 mb.

A Hurricane Warning was in effect for the portion of the coast from High Island, Texas to Morgan City, Louisiana.  Tropical Storm Warnings were in effect for the portions of the coast from Sargent to High Island Texas and from Morgan City, Louisiana to the Mouth of the Pearl River.  The Tropical Storm Warning included New Orleans, Lake Pontchartrain and Lake Maurepas.

Hurricane Delta started to weaken slowly on Friday morning as it moved into a less favorable environment.  An upper level trough over the south central U.S.  was producing southwesterly winds which were blowing toward the top of Delta.  Those winds were starting to increase the vertical wind shear.  They were also inhibiting upper level divergence to the south of the hurricane which was causing the surface pressure to increase.

Even though it was weakening, Hurricane Delta remained a formidable hurricane.  There was an eye with a diameter of 40 miles (65 km) at the center of Delta.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolving the core of Hurricane Delta were already dropping heavy rain over parts of southeast Texas and southwest Louisiana.

Winds to hurricane force extended out 40 miles (65 km) from the center of Hurricane Delta.  Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.  The Hurricane Intensity Index (HII) for Hurricane Delta was 20.6.  The Hurricane Size Index (HSI) was 13.8 and the Hurricane Wind Intensity Size Index (HWISI) was 34.4.  Hurricane Delta was capable of causing regional major damage.

The upper level trough over the south central U.S. will steer Hurricane Delta toward the north-northeast during the next 12 to 24 hours.  On its anticipated track Delta will make landfall on the coast of Louisiana east of Cameron in a few hours.  Hurricane Delta will bring strong winds and heavy rain to parts of the area around Lake Charles that were affected by Hurricane Laura a few weeks ago.  Only temporary repairs have been made to numerous structures.  So, wind and rain damage will be greater than they would have been if all buildings were still intact.  Hurricane Delta will also cause a storm surge of 9 to 12 feet (3 to 4 meters) along the coast.  Locally heavy rain will cause flash floods in some locations.  Widespread power outages could also occur.

Delta Strengthens Back to a Major Hurricane

Hurricane Delta strengthened back to a major hurricane on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Hurricane Delta was located at latitude 24.8°N and longitude 93.4°W which put it about 345 miles (555 km) south of Cameron, Louisiana.  Delta was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (220 km/h).  The minimum surface pressure was 959 mb.

A Hurricane Warning was in effect for the portion of the coast from High Island, Texas to Morgan City, Louisiana.  Tropical Storm Warnings were in effect for the portions of the coast from Sargent to High Island, Texas and from Morgan City, Louisiana to the Mouth of the Pearl River.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

Hurricane Delta strengthened steadily on Thursday.  A circular eye with a diameter of 35 miles (55 km) formed at the center of Delta.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Delta.  Storms near the core generated upper level divergence that pumped mass away from the hurricane.  The removal of mass allowed the surface pressure to decrease and the wind speed to increase.

The circulation around Hurricane Delta increased in size on Thursday.  Winds to hurricane force extended out 35 miles (55 km) from the center of circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Delta was 20.6.  The Hurricane Size Index (HSI) was 12.7 and the Hurricane Wind Intensity Size Index (HWISI) was 33.3.  Delta was capable of causing regional major damage.

Hurricane Delta will move through an environment favorable for intensification during the next 12 to 18 hours.  Delta will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Delta will continue to intensify in the short term and it could reach Category 4 on the Saffir-Simpson Scale.

Hurricane Delta will move around the western end of a high pressure system on Friday.  The high will steer Delta toward the north.  An upper level trough over the south central U.S. will turn Delta toward the north-northeast on Friday afternoon.  On its anticipated track Hurricane Delta will make landfall on the coast of Louisiana late on Friday afternoon or on Friday evening.

Hurricane Delta could hit the same area southeast of Lake Charles, Louisiana that was affected by Hurricane Laura.  Delta will bring strong winds and heavy rain to Louisiana.  It could cause a storm surge of 10 to 15 feet (3 to 5 meters) along the coast.  A number of structures in the region have temporary blue tarps in place of permanent roofs.  Hurricane Delta could cause more than the usually expected wind and rain damage in areas affected by Hurricane Laura.  There are also likely to be widespread power outages in the area.

Hurricane Delta Clips Northeast Yucatan, Watches Issued for U.S.

Hurricane Delta clipped the northeastern corner of the Yucatan Peninsula on Wednesday morning and watches were issued for portions of the U.S. Gulf Coast.  At 11:00 a.m EDT on Wednesday the center of Hurricane Delta was located at latitude 21.4°N and longitude 88.0°W which put it about 65 miles (105 km) west-southeast of Cabo Catoche, Mexico.  Delta was moving toward the northwest at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 975 mb.

A Hurricane Warning was in effect for the portion of the coast from Tulum to Dzilam, Mexico including Cozumel.  A Hurricane Watch was issued for the portion of the coast from High Island, Texas to Grand Isle, Louisiana.  Tropical Storm Warnings were in effect for the portions of coast from Punta Herrero to Tulum, Mexico and from Dzilam to Progreso, Mexico.  Tropical Storm Watches were issued for the portions of the coast from San Luis Pass to High Island, Texas and from Grand Isle, Louisiana to Bay St. Louis, Mississippi including New Orleans, Lake Pontchartrain and Lake Maurepas.

Hurricane Delta brought strong winds and locally heavy rain to the northeastern Yucatan Peninsula and the island of Cozumel on Wednesday morning.  The center of Delta officially made landfall on the coast about 20 miles (30 km) south of Cancun, Mexico.  A weather station in Cancun reported a sustained wind speed of 84 m.p.h. (135 km/h) and a wind gust of 106 m.p.h. (170 km/h).

Hurricane Delta weakened during Tuesday night before it made landfall on the Yucatan Peninsula.  It appeared as though an eyewall replacement cycle occurred in Hurricane Delta.  The original small eyewall, which had a diameter of 4 miles (6 km) weakened.  Since the strongest winds were occurring in that eyewall, the wind speeds decreased when it weakened.  Microwave satellite imagery suggested that a new, larger eye was developing at the center of Delta when it made landfall.

The eyewall replacement cycle also caused the size of the circulation around Hurricane Delta to increase.  Winds to hurricane force extended out 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out 130 miles (210 km) from the center of Delta.  The Hurricane Intensity Index (HII) for Hurricane Delta was 17.8.  The Hurricane Size Index (HSI) was 10.2 and the Hurricane Wind Intensity Size (Index (HWISI) was 28.0.  Delta was capable of causing regional serious damage.

Hurricane Delta will move through an environment favorable for intensification when it moves over the southern Gulf of Mexico.  Delta will move over water where the Sea Surface Temperature is near 29°C.  It will move under the western part of an upper level ridge.  The upper level winds are weaker in that part of the ridge and there will be less vertical wind shear.  Hurricane Delta is likely to intensify during the next 24 hours.  An upper level trough over the south central U.S. will produce southerly winds which will blow toward the top of Delta on Friday.  Those winds winds cause more vertical wind shear and Delta will likely weaken when it approaches the Gulf Coast.

Hurricane Delta will move around the western end of a high pressure system over the western Atlantic Ocean.  The high will steer Delta toward the northwest during the next 24 hours.  Hurricane Delta will move more toward the north on Thursday when it reaches the western end of the high pressure system.  The upper level trough over the south central U.S. will turn Delta toward the north-northeast on Friday.  On its anticipated track Hurricane Delta will approach the coast of Louisiana on Friday.  Delta could be near the threshold for a major hurricane when it approaches the coast.

Hurricane Delta will bring strong winds and locally heavy rain to Louisiana on Friday.  The wind will push water toward the coast.  A storm surge of 10 to 15 feet (3 to 5 meters) could occur in some locations.

Delta Rapidly Intensifies to a Major Hurricane

Hurricane Delta rapidly intensified into a major hurricane over the Northwestern Caribbean Sea on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Hurricane Delta was located at latitude 18.2°N and longitude 82.6°W which put it about 320 miles (520 km) east-southeast of Cozumel, Mexico.  Delta was moving toward the west-northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 954 mb.

A Hurricane Warning was in effect for the portion of the coast from Tulum to Dzilam, Mexico including Cancun and Cozumel.  Tropical Storm Warnings were in effect for the Cayman Islands, the Isle of Youth and Pinar del Rio, Cuba.  Tropical Storm Warnings were also in effect for the portions of the coast from Punta Herrero to Tulum and from Dzilam to Progreso, Mexico.  A Tropical Storm Watch was in effect for La Habana, Cuba.

Hurricane Delta rapidly intensified into a major hurricane on Tuesday morning.  A small eye with a diameter of six miles (10 km) was at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolving around the core of Delta.  Storms near the core generated upper level divergence which pumped large quantities of mass away from the hurricane.  The removal of mass allowed the surface pressure to decrease rapidly which contributed to the rapid intensification of Hurricane Delta.

The circulation around Hurricane Delta was relatively small.  Winds to hurricane force extended out 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Delta.  The Hurricane Intensity Index (HII) for Hurricane Delta was 25.1.  The Hurricane Size Index (HSI) was 7.6 and the Hurricane Wind Intensity Size Index (HWISI) was 32.7.

Hurricane Delta will move through an environment favorable for intensification during the next 18 hours.  Delta will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Delta is likely to continue to intensify rapidly during the next 12 hours.  It could reach Category 5 on the Saffir-Simpson Scale.

Hurricane Delta will move around the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Delta toward the northwest during the next 48 hours.  Hurricane Delta will move more toward the north on Thursday when it reaches the western end of the high pressure system.  On its anticipated track Hurricane Delta will reach the northeastern part of the Yucatan Peninsula on Tuesday night.  Delta will bring damaging winds and locally heavy rain to area around Cancun and Cozumel.  Hurricane Delta will then move over the Gulf Mexico.  Delta could approach the coast of Louisiana on Friday night.  It could bring hurricane conditions to New Orleans on Saturday.

Delta Rapidly Strengthens into a Hurricane

Former Tropical Storm Delta rapidly strengthened into a hurricane on Monday.  At 8:00 p.m. EDT on Monday the center of Hurricane Delta was located at latitude 16.5°N and longitude 79.6°W which put it about 220 miles (355 km) south-southeast of Grand Cayman.  Delta was moving toward the west-northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 980 mb.

Hurricane Warnings were in effect for Pinar del Rio, Cuba and for the portion of the coast from Tulum to Rio Lagartos, Mexico including Cancun and Cozumel.  Hurricane Watches were in effect for Isle of Youth and Artemisa, Cuba.  A Tropical Storm Warning was in effect for the Cayman Islands.  A Tropical Storm Watch was in effect for La Habana, Cuba.

Delta strengthened from a tropical depression into a hurricane on Monday.  An elliptical eye with a diameter of 18 miles (29 km) formed at the center of Hurricane Delta.  The eye was surrounded by ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Delta.  Storms near the core generated upper level divergence which pumped mass away from the hurricane.  The removal of mass allowed the surface pressure to decrease rapidly.  Winds to hurricane force extended out 15 miles (25 km) from the center o circulation.  Winds to tropical storm extended out 70 miles (110 km) from the center.

Hurricane Delta will move through an environment favorable for intensification during the next 36 hours.  Delta will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Delta will continue to intensify and it could strengthen into a major hurricane within 24 hours.

Hurricane Delta will move around the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Delta toward the northwest during the next 48 hours.  On its anticipated track Hurricane Delta will be near Cancun and Cozumel in about 24 hours.  Delta could be a major hurricane at that time.  Hurricane Delta will move more toward the north when it moves around the western end of the high on Thursday.  Delta could approach the central Gulf Coast on Thursday night.

Elsewhere, Tropical Depression Gamma was weakening just north of the Yucatan Peninsula.  At 5:00 p.m. EDT on Monday the center of Tropical Depression Gamma was located at latitude 22.1°N and longitude 88.1°W which put it about 115 miles (185 km) east-northeast of Progreso, Mexico.  Gamma was moving toward the southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1005 mb.

Tropical Storm Delta Develops South of Jamaica

Former Tropical Depression Twentysix strengthened into Tropical Storm Delta south of Jamaica on Monday morning.  At 8:00 a.m. EDT on Monday the center of Tropical Storm Delta was located at latitude 16.4°N and longitude 78.4°W which put it about 65 miles east of the Mouth of the Mississippi River and about 130 miles south of Negril, Jamaica.  Delta was moving toward the west-northwest at 9 m.p.h.  The maximum sustained wind speed was 40 m.p.h.  The minimum surface pressure was 1004 mb.

A Hurricane Watch was in effect for the Isle of Youth, Pinar del Rio and Artemisa, Cuba.  A Tropical Storm Warning was in effect for the Cayman Islands.  A Tropical Storm Watch was in effect for La Habana, Cuba.

More thunderstorms developed near the center of former Tropical Depression Twentysix on Monday morning and the National Hurricane Center upgraded the system to Tropical Storm Delta.  The circulation around Tropical Storm Delta was still organizing.  Bands of showers and thunderstorms were revolving around the center of Delta.  The strongest rainbands were in the southern half of the circulation.  Storms near the center were generating upper level divergence which was pumping mass away from the tropical storm.  The removal of mass allowed the pressure to decrease, which caused the wind speed to increase.

Tropical Storm Delta will move through an environment which will be very favorable for intensification.  Delta will move over water where the Sea Surface Temperature is near 30˚C.  It will move under an upper level ridge where the winds are weak.  There will be little vertical wind shear.  Tropical Storm Delta will intensify and it could strengthen into a hurricane by Tuesday night.  Once an inner core with an eye and an eyewall develops, Delta could intensify rapidly.  There is a chance Tropical Storm Delta could strengthen into a major hurricane.

Tropical Storm Delta will move around the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Delta toward the northwest during the next few days.  On its anticipated track Tropical Storm Delta could reach the Cayman Islands on Monday night.  Delta could be near the western end of Cuba by Tuesday night and it is likely to be a hurricane at that time.  Delta could approach the central Gulf Coast on Thursday night.  It could be a major hurricane when it approaches the Gulf Coast.

Elsewhere, Tropical Storm Gamma weakened as it meandered north of the Yucatan Peninsula.  Strong southerly winds in the upper levels blew the top off of Tropical Storm Gamma on Sunday night.  At 8:00 a.m. EDT on Monday the center of Tropical Storm Gamma was located at latitude 22.6°N and longitude 87.5°W which put it about 165 miles (270 km) east-northeast of Progreso, Mexico.  Gamma was moving toward the south-southwest at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1001 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Cancun to Dzilam, Mexico.  A Tropical Storm Watch was in effect for the portion of the coat from Dzilam to Campeche, Mexico.

Teddy Brings Wind and Rain to Nova Scotia

Former Hurricane Teddy brought wind and rain to Nova Scotia on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Teddy was located at latitude 46.0°N and longitude 61.3°W which put it about 150 miles (240 km) southwest of Port aux Basques, Newfoundland.  Teddy was moving toward the north-northeast at 26 m.p.h. (43 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 967 mb.

A Tropical Storm Warning was in effect for the portion of the south coast of Nova Scotia from Ecum Secum to Meat Cove.  A Tropical Storm Warning was also in effect for the portion of the coast from Port aux Basques to Francois, Newfoundland.  Tropical Storm Watches were in effect for the portion of the coast from Meat Cove to Brule, Nova Scotia, for the Magdalen Islands and for Prince Edward Island.

The center of former Hurricane Teddy made landfall near Ecum Secum, Nova Scotia on Wednesday morning.  The structure of Teddy made a transition from one typical of a tropical cyclone to one more like an extratropical cyclone as it approached the coast of Nova Scotia.  The area of stronger winds expanded.  Winds to tropical storm force extended out 200 miles (320 km) from the center of Teddy.  The heaviest rain fell over eastern Nova Scotia.  The large circulation around Teddy was producing large waves which caused water level rises and beach erosion as far away as the East Coast of the U.S.

An upper level trough over eastern North America will steer Teddy quickly toward northeast during the rest of today.  On its anticipated track Tropical Storm Teddy will bring gusty winds and heavy rain to parts of southwestern Newfoundland during the next few hours.

Elswhere, former Tropical Storm Beta was dropping heavy rain over parts of Louisiana.  At 11:00 a.m. EDT on Wednesday the center of Tropical Depression Beta was located at latitude 30.2°N and longitude 94.2°W which put it about 60 miles (95 km) west of lake Charles, Louisiana.  Beta was moving toward the east-northeast at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h_.  The minimum surface pressure was 1007 mb.

Tropical Depression Beta dropped heavy rain over southeastern Texas on Tuesday.  There were numerous reports of flooding around Houston.  Beta was moving over western Louisiana on Wednesday morning and light to moderate rain was falling over many parts of the state.  Flash Flood Watches were in effect for much of Louisiana and western Mississippi.  Beta will move slowly toward the northeast during the next 48 hours.  Moderate to heavy rain could spread over Mississippi, Tennessee, northern Alabama, western North Carolina and western Virginia.

Hurricane Teddy Heads for Nova Scotia, Beta Reaches Texas

Hurricane Teddy headed for Nova Scotia on Monday night as Tropical Storm Beta reached the coast of Texas.  At 11:00 p.m. EDT on Monday the center of Hurricane Teddy was located at latitude 35.6°N and longitude 61.5°W which put it about 630 miles (1015 km) south of Halifax, Nova Scotia.  Teddy was moving toward the north at 25 m.p.h. (41 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 956 mb.

A Tropical Storm Warning was in effect for the south coast of Nova Scotia from Digby to Meat Cove.  Tropical Storm Watches were in effect for the portions of the coast from Meat Cove to Tidnish and from Digby to Fort Lawrence.  Tropical Storm Watches were also in effect for Prince Edward Island, the Magdalen Islands and from Port aux Basques to Francois, Newfoundland.

The circulation around Hurricane Teddy expanded as it began a transition to an extratropical cyclone.  Winds to hurricane force extended out 100 miles (160 km) from the center of Teddy.  Winds to tropical storm force extended out 275 miles (445 km) from the center.  Drier air was wrapping around the southern side of Hurricane Teddy.  The strongest thunderstorms were in bands in the northern half of the hurricane.  Bands in the southern half of the circulation consisted primarily of showers and lower clouds.

An upper level trough over eastern North America will cause strong southerly winds which will blow toward the top of Hurricane Teddy.  Those winds will cause strong vertical wind shear and they will contribute to the extratropical transition of Teddy.  Hurricane Teddy will move over much cooler water when it approaches Nova Scotia.  Teddy will transform into a strong extratropical cyclone.

Hurricane Teddy will be steered rapidly toward the north by the upper level trough over eastern North America.  On its anticipated track Hurricane Teddy will approach Nova Scotia on Tuesday night.  Teddy will bring strong winds and heavy rain to Nova Scotia and southwestern Newfoundland.

Elsewhere, slow moving Tropical Storm Beta reached the coast of Texas on Monday night.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Beta was located at latitude 28.4°N and longitude 96.3°W which put it about 5 miles (10 km) east of Port O Connor, Texas.  Beta was moving toward the northwest at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Port Aransas, Texas to Morgan City Louisiana.

Tropical Storm Beta weakened gradually on Monday as it moved slowly toward the coast of Texas.  Drier air continued to get pulled into the circulation which limited the development of new thunderstorms.  Without updrafts and downdrafts to transport momentum vertically, the circulation around Beta slowly spun down.

Even though Tropical Storm Beta weakened on Monday, its winds pushed water toward the coast of Texas.  Water levels rose along the coast and there were some reports of damage.  Waves contributed to beach erosion.  Moderate rain was falling over the region between Houston and Victoria, Texas.  The rain could cause flooding in some locations.

Tropical Storm Beta was forecast to move slowly toward the northeast along the coast of Texas during the next 24 to 36 hours.  Beta will continue to weaken, but winds will blow water toward the coast from several more days.  Locally heavy rain will continue to create a risk of floods until Tropical Storm Beta moves away from the area.

Tropical Storm Beta Moves Toward Texas

Tropical Storm Beta moves slowly toward the coast of Texas on Sunday.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Beta was located at latitude 29.6°N and longitude 94.5°W which put it about 130 miles (210 km) east-southeast of Port Oconnor, Texas.  Beta was moving toward the west-northwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 995 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Port Aransas, Texas to Morgan City, Louisiana.  A Tropical Storm Watch was in effect from Baffin Bay to Port Aransas, Texas.

Tropical Storm Beta exhibited more organization on Sunday afternoon.  Thunderstorms developed near the center of circulation and radar indicated the potential formation of an eye at the center of Beta.  The thunderstorms near the center weakened on Sunday night.  It appeared that drier air over Texas was pulled into the circulation around Tropical Storm Beta.  The drier air mixed into the core of Beta which caused thunderstorms to weaken.  When the thunderstorms near the center weakened, it appeared that the upper part of the circulation drifted northeast of the low level circulation.  Even though the thunderstorms weakened a reconnaissance plane on Sunday night found that the wind speeds had not decreased.  The strongest winds were occurring in the northeastern quadrant of Tropical Storm Beta.  Winds to tropical storm force extended out 200 miles (320 km) in that quadrant of the circulation.  Winds to tropical storm force only extended out 50 miles from the center in the southern half of the circulation.

Tropical Storm Beta will move through an environment only marginally favorable for intensification on Monday.  Beta will move over water where the Sea Surface Temperature is near 30°C.  It will continue to be surrounded by drier air, which will inhibit intensification.  Tropical Storm Beta could maintain its intensity if new thunderstorms develop near the center of circulation.  If thunderstorms do not develop near the center, then Beta will slowly weaken.

Tropical Storm Beta will move around the southwestern part of a large high pressure system over the eastern U.S.  The high will steer Beta toward the west-northwest.  On its anticipated track Tropical Storm Beta will approach the coast of Texas near Matagorda Bay on Monday evening.  Winds blowing water toward the coast will cause a storm surge of 3 to 6 feet (1 to 2 meters).

Elsewhere, Hurricane Teddy was moving closer to Bermuda.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Beta was located at latitude 29.4°N and longitude 63.6°W which put it about 210 miles (340 km) south-south east of Bermuda.  Teddy was moving toward the north-northwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 963 mb.

A Tropical Storm Warning was in effect for Bermuda.  A Tropical Storm Watch was issued for the portion of the coast from Lower East Pubnico to Canso, Nova Scotia.
