Tropical Depression Two Strengthens to Tropical Storm Bill

Former Tropical Depression Two strengthened to Tropical Storm Bill east-northeast of Cape Hatteras on Monday night. At 11:00 p.m. EDT on Monday the center of Tropical Storm Bill was located at latitude 36.7°N and longitude 69.8°W which put it about 335 miles (540 km) east-northeast of Cape Hatteras, North Carolina. Bill was moving toward the northeast at 23 m.p.h. (37 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 1003 mb.

The circulation around former Tropical Depression Two intensified on Monday night and the National Hurricane Center upgraded the system to Tropical Storm Bill. Even though the circulation around Bill was stronger, the distribution of thunderstorms was asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Tropical Storm Bill. Bands on the western side of Bill consisted mainly of showers and lower clouds. Winds to tropical storm force extended out 70 miles (110 km) in the southeastern quadrant of Tropical Storm Bill. The wind was blowing at less than tropical storm force in the other quadrants of Bill. An upper level trough east of the Great Lakes was producing strong southwesterly winds that were blowing toward the top of Tropical Storm Bill. Those winds were causing moderate vertical wind shear and they were the cause of the asymmetrical distribution of thunderstorms.

Tropical Storm Bill will move through an environment that will be only marginally favorable for intensification during the next 24 hours. Bill will move over the warmer water in the Gulf Stream where the Sea Surface Temperatures are near 27°C on Tuesday. However, the upper level trough east of the Great Lakes will continue to cause moderate vertical wind shear, which will inhibit intensification. Tropical Storm Bill could intensify a little more on Tuesday, but the wind shear is likely to increase by Tuesday night.

The upper level trough east of the Great Lakes will steer Tropical Storm Bill rapidly toward the northeast. On its anticipated track Tropical Storm Bill will pass southeast of Nova Scotia on Tuesday. Bill could approach southeast Newfoundland on Tuesday night.

Tropical Depression Two Forms East of Cape Hatteras

Tropical Depression Two formed east of Cape Hatteras on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Depression Two was located at latitude 35.0°N and longitude 73.7°W which put it about 105 miles (165 km) east of Cape Hatteras, North Carolina. The tropical depression was moving toward the northeast at 21 m.p.h. (33 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 1006 mb.

More thunderstorms developed near the center of a low pressure system east of North Carolina on Monday morning and the National Hurricane Center designated the system as Tropical Depression Two. Bands of showers and thunderstorms also developed and the bands began to revolve around the center of the depression. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical depression. The removal of mass cause the surface pressure to decrease.

Tropical Depression Two will move through an environment favorable for intensification during the next 24 hours. The tropical depression will move over the warmer water of the Gulf Stream where the Sea Surface Temperatures are near 27°C. An upper level trough east of the Great Lakes will produce southwesterly winds which will blow toward the top of the depression. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. Tropical Depression Two will likely strengthen to a tropical storm during the next 12 hours.

The upper level trough east of the Great Lakes will steer Tropical Depression Two rapidly toward the northeast. On its anticipated track Tropical Depression Two will move away from the U.S. It could pass southeast of Nova Scotia on Tuesday.

Hurricane Epsilon Passes East of Bermuda

Hurricane Epsilon passed east of Bermuda on Thursday night. At 11:00 p.m. EDT on Thursday the center of Hurricane Epsilon was located at latitude 32.6°N and longitude 61.6°W which put it about 300 miles (485 km) east of Bermuda. Epsilon was moving toward the north-northwest at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 968 mb. The government of Bermuda discontinued the Tropical Storm Warning.

Hurricane Epsilon weakened as it passed east of Bermuda on Thursday night. The eye was no longer apparent on satellite images. Breaks developed in the ring of thunderstorms around the eye. Bands of showers and thunderstorms continued to revolve around the core of Hurricane Epsilon. Storms near the core still generated upper level divergence which pumped mass away to the east of Epsilon. Winds to hurricane force extended out 20 miles (30 km) from the center of circulation. Winds to tropical storm force extended out 240 miles (390 km) from the center.

Hurricane Epsilon will move through an environment that could allow it to maintain its intensity for another 24 to 36 hours.  Epsilon will move over water where the Sea Surface Temperature is near 26°C.  It will be in an area where the upper level winds are weak and there will be little vertical wind shear.  Upper level westerly winds in the middle latitude will create more vertical wind shear on Saturday. The wind shear will cause Epsilon to start to weaken and it will begin a transition to an extratropical cyclone.

Hurricane Epsilon will move around the southwestern part of ridge of high pressure over the Northeastern Atlantic Ocean.  The ridge will steer Epsilon toward the north during the next 24 hours.  Epsilon will move more toward the northeast during the weekend when it reaches the westerly winds in the middle latitudes. On its anticipated track Hurricane Epsilon will pass southeast of Nova Scotia and Newfoundland during the weekend.

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.

Tropical Storm Kyle Forms East of U.S.

Tropical Storm Kyle formed off the East Coast of the U.S. on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Kyle was located at latitude 37.7°N and longitude 71.7°W which put it about 185 miles (300 km) southeast of Atlantic City, New Jersey.  Kyle was moving toward the east-northeast at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1008 mb.

Based on data from satellites and surface observations the National Hurricane Center (NHC) determined that a low pressure system off the East Coast of the U.S. possessed characteristics of a tropical cyclone and winds to tropical storm force.  NHC designated the system as Tropical Storm Kyle on Friday afternoon.  Kyle had a well defined low level center of circulation.  Many of the stronger thunderstorms were occurring in bands in the eastern half of Tropical Storm Kyle.  Bands in the western half of the circulation consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 80 miles to the southeast of the center of circulation.  Winds in the other parts of Kyle were blowing at less than tropical storm force.

Tropical Storm Kyle will move through an environment marginally favorable for intensification during the next 24 hours.  Kyle will move over water where the Sea Surface Temperature is near 27°C.  An upper level trough over eastern Canada and the Great Lakes will produces southwesterly winds which will blow toward the top of tropical storm Kyle.  Those winds will cause moderate vertical wind shear and they will inhibit intensification.  Tropical Storm Kyle could strengthen a little more during the next day or so.

The southwesterly winds will steer Tropical Storm Kyle toward the east-northeast during the next several days.  On its anticipated track Kyle is forecast to pass south of Nova Scotia and Labrador.

Elsewhere over the Atlantic Ocean, Tropical Storm Josephine was spinning east of the northern Leeward Islands.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Josephine was located at latitude 17.8°N and longitude 56.1°E which put it about 460 miles (740 km) east of the northern Leeward Islands.  Josephine was moving toward the west-northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1004 mb.

Subtropical Depression Four Forms Southeast of Cape Cod

Subtropical Depression Four developed southeast of Cape Cod, Massachusetts on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Subtropical Depression Four was located at latitude 38.2°N and longitude 65.7°W which put it about 310 miles (495 km) southeast of Cape Cod, Massachusetts.  The depression was moving toward the east-northeast at 9 m.p.h. (15 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 1009 mb.

The structure of a previously non-tropical low pressure system southeast of Cape Cod evolved into a more symmetrical circular shape on Monday.  Bands of showers and thunderstorms revolved more closely around the center of the low.  The low pressure system exhibited a more tropical like structure on visible satellite imagery.  However, the National Hurricane Center (NHC) observed that the surface low was under an upper low which meant the system had a cold core in the upper troposphere.  So, NHC designated the system as Subtropical Depression Four when it initiated advisories on Monday afternoon.

The circulation around Subtropical Depression Four had a hybrid structure with a tropical like appearance in the lower levels and a non-tropical cold core in the upper levels.  The depression will move through an environment favorable for intensification during the next 12 to 18 hours.  The core of the depression will move near the northern part of the Gulf Stream where the Sea Surface Temperature is near 26°C.  It will move near the south side of the core of the upper low where the winds are weaker.  Those winds will cause some vertical wind shear, but the shear will not be too strong during the next 12 hours.  The depression could strengthen into a subtropical storm.  There is a chance that the circulation could develop a warm core in the upper levels if the depression stays near the Gulf Stream.  The warm water in the Gulf Stream and the cold air in the upper troposphere will enhance instability which will contribute to the development of thunderstorms.  If thunderstorms release enough latent energy in the upper troposphere, then a warm core could form and the system could make an additional transition into a tropical storm.

Subtropical Depression Four is likely to move in tandem with the upper low during the next day or two.  The upper low will move toward the east-northeast on Tuesday and then it will move more toward the northeast on Wednesday.  On its anticipated track Subtropical Depression Four will move away from the northeast U.S.  The depression will remain south of Nova Scotia, but it could pass near southeastern Newfoundland on Thursday.

Hurricane Dorian Brings Powerful Winds to Nova Scotia

Hurricane Dorian brought powerful winds to Nova Scotia on Saturday.  At 8:00 p.m. EDT on Saturday the center of Hurricane Dorian was located at latitude 45.0°N and longitude 67.9°W which put it about 45 miles (75 km) northeast of Halifax, Nova Scotia.  Dorian was moving toward the northeast at 30 m.p.h. (48 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 960 mb.

Hurricane Warnings were in effect for Lower East Pubnico to Brule, Nova Scotia and from Indian Harbour to Hawke’s Bay, Newfoundland. Hurricane Watches were in effect for Prince Edward Island and for the Magdalen Islands. Tropical Storm Warnings were issued for Prince Edward Island and from Avonport to Lower East Pubnico, Nova Scotia. A Tropical Storm Warning was in effect for New Brunswick from Fundy National Park to Shediac. A Tropical Storm Warning was issued for the portion of the coast from Indian Harbour to Stone’s Cove, Newfoundland. Tropical Storm Warnings were issued for the portions of the coast from Hawke’s Bay to Fogo Island and from Mutton Bay to Mary’s Harbour.

Hurricane Dorian maintained its intensity and increased in size on Saturday while it sped across the northwestern Atlantic Ocean to the Canadian Maritime provinces.  Winds to hurricane force extended out about 115 miles (185 km) on the southern side of Hurricane Dorian.  Winds to tropical storm force extended out about 300 miles (480 km) from the center of circulation.  The Hurricane Intensity Index (HII) for Hurricane Dorian was 16.5.  The Hurricane Size Index (HSI) was 26.3 and the Hurricane Wind Intensity Size Index (HWISI) was 42.8.  Hurricane Dorian was capable of causing widespread serious damage.

There were reports of wind damage and widespread power outages around Nova Scotia even before the center of Hurricane reached that area.  The large circulation around Dorian brought tropical storm force winds to Nova Scotia a few hours before the center made landfall.  The center of Hurricane Dorian officially made landfall south of Halifax, Nova Scotia on Saturday evening.

Hurricane Dorian had almost completed a transition to a large powerful extratropical cyclone.  That transition contributed to the increase in size of the circulation.  The strongest part of Hurricane Dorian will move across Nova Scotia during the next few hours.  The winds are likely to cause additional damage on Saturday night.  Hurricane Dorian will race across Nova Scotia, Cape Breton Island and New Brunswick on Saturday night.  Dorian will move over Newfoundland and southeastern Labrador on Sunday.  Hurricane Dorian has the potential to cause serious damage in all of those locations.

Hurricane Dorian Makes Landfall at Cape Hatteras, Threatens Canadian Maritimes

Hurricane Dorian made an official landfall at Cape Hatteras, North Carolina on Friday morning and posed a serious threat to the Canadian Maritime provinces.  At 5:00 p.m. EDT on Friday the center of Hurricane Dorian was located at latitude 36.9°N and longitude 72.7°W which put it about 330 miles (530 km) south-southwest of Nantucket, Massachusetts.  Dorian was moving toward the northeast at 24 m.p.h. (39 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 surace pressure was 958 mb.

A Tropical Storm Warning was in effect for the portion of the coast from the North Carolina/Virginia border to Fenwick Island, Delaware, and for Chesapeake Bay south of Drum Point.  A Tropical Storm Warning was in effect for the portion of the coast from Woods Hole to Sagamore Beach, Massachusetts including Martha’s Vineyard and Nantucket.  A Tropical Storm Warning was in effect for the portion of the coast from Bar Harbor to Eastport, Maine.  A Hurricane Warning was in effect from Hubbards to Avonport, Nova Scotia.  A Hurricane Watch was issued for Prince Edward Island, Avonport to Hubbards, Nova Scotia, the Magdalen Islands, Parson’s Pond to Indian Harbour, Newfoundland.  Tropical Storm Warnings were issued for Prince Edward Island and from Avonport to Hubbards, Nova Scotia.  A Tropical Storm Watch was in effect for New Brunswick from Fundy National Park to Shediac.  A Tropical Storm Watch was issued for Newfoundland from Francois to Boat Harbor.  A Tropical Storm Watch was  issued for the portion of the coast from Parson’s Pond to Triton, and from Indian Harbour to Stone’s Cove, Newfoundland.

The National Hurricane Center determined that the center of Hurricane Dorian passed over Cape Hatteras and identified that as the point of landfall.  Hurricane Dorian has been moving rapidly away from the coast since that time.  Hurricane Dorian remained a large, well organized hurricane.  A circular eye with a diameter of 35 miles (55 km) was apparent on satellite images.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Winds to hurricane force extended out about 80 miles (130 km) from the center of circulation.  Winds to tropical storm force extended out about 230 miles (370 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Dorian was 13.9.  The Hurricane Size Index (HSI) was 23.3 and the Hurricane Wind Intensity Size Index (HWISI) was 43.2.

Hurricane Dorian will move through an environment favorable for intensification on Saturday.  Dorian will start out over water where the Sea Surface Temperature is near 27°C.  Dorian will move over cooler water later on Saturday.  An upper level trough over the eastern U.S. will contribute to upper level divergence, which may pump out enough mass to allow the surface pressure to decrease.  Hurricane Dorian will start to make a transition to an extratropical cyclone later on Saturday.  The interaction of colder and warmer air could also provide additional energy to the transitioning hurricane.  There is a chance that Hurricane Dorian could strengthen to a Category 2 hurricane on the Saffir-Simpson Scale on Saturday.

The upper level trough over the eastern U.S. will steer Hurricane Dorian rapidly toward the northeast during the weekend.  On its anticipated track, Dorian will pass southeast of Massachusetts on Saturday morning.  Hurricane Dorian could reach Nova Scotia by Saturday afternoon.  Dorian could be one of the strongest hurricanes to affect the Canadian Maritime provinces.  It will be capable of causing widespread serious damage.
