Tropical Depression Ten Forms over the Yucatan Channel

Tropical Depression Ten formed over the Yucatan Channel on Saturday afternoon. At 5:00 p.m. EDT on Saturday the center of Tropical Depression Ten was located at latitude 21.1°N and longitude 86.1°W which put it about 65 miles (105 km) northeast of Cozumel. The tropical depression was stationary. 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 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Tulum to Rio Lagartos, Mexico. The Tropical Storm Warning included Cozumel. A Tropical Storm Warning was also in effect for the Cuban Provinces of Pinar del Rio and Isle of Youth.

A low pressure system over the Yucatan Peninsula exhibited more organization on Saturday afternoon and the U.S. National Hurricane Center designated it as Tropical Depression Ten. The circulation around Tropical Depression Ten was still organizing. There was a weak center of circulation at the surface. Radar images from western Cuba indicated that there was a stronger circulation in the middle troposphere. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center started to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Ten will be in an environment mostly favorable for intensification during the next 24 hours. The tropical depression will be over water where the Sea Surface Temperatures are near 30°C. It will be under an upper level ridge over the Yucatan Channel. The winds are weak in the upper level ridge and there will be little vertical wind shear. However, much of the air moving around the western side of Tropical Depression Ten will pass over the northeastern Yucatan Peninsula. Some of the air in the western side of the tropical depression will pass over western Cuba. The flow of air over land will inhibit intensification, but it probably will not prevent intensification. Tropical Depression Ten could intensify slowly on Sunday.

Tropical Depression Ten will be in a region where the steering currents are weak during the next 24 hours. Tropical Depression Ten may not move much on Sunday. A high pressure system over the western Atlantic Ocean will start to steer the tropical depression toward the north early next week. Tropical Depression Ten is likely to strengthen when it moves over the eastern Gulf of Mexico.

Tropical Depression Ten will drop heavy rain over parts of the northeastern Yucatan Peninsula and western Cuba. Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Franklin strengthened over the Atlantic Ocean south-southwest of Bermuda. At 5:00 p.m. EDT on Saturday the center of Hurricane Franklin was located at latitude 23.8°N and longitude 67.5°W which put it about 610 miles (980 km) south-southwest of Bermuda. Franklin was moving toward the north-northwest at 8 m.p.h. (13 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 982 mb.

Tropical Storm Ian Passes South of Jamaica

Tropical Storm Ian passed south of Jamaica on Saturday night. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Ian was located at latitude 14.7°N and longitude 77.7°W which put it about 395 miles (630 km) southeast of Grand Cayman. Ian was moving toward the west at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1002 mb.

A Hurricane Warning was in effect for Grand Cayman. Hurricane Watches were in effect for the Cuban provinces of Isla de Juventud, Pinar del Rio and Artemisa. Tropical Storm Watches were in effect for Little Cayman and Cayman Brac. Tropical Storm Watches were also in effect for the Cuban provinces of La Habana, Mayabeque and Matanzas.

Tropical Storm Ian gradually got better organized on Saturday. More thunderstorms developed near the center of circulation. Bands of showers and thunderstorms formed and began to revolve around the center of Ian’s circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 60 miles (95 km) in the northern side of Ian. The winds in the southern half of Tropical Storm Ian were blowing at less than tropical storm force.

Tropical Storm Ian will move through an environment very favorable for intensification during the next 48 hours. Ian will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Ian is likely to intensify more quickly on Sunday. Tropical Storm Ian is likely to intensify to a hurricane during the next 24 hours. Ian could intensify rapidly after an inner core with an eye and an eyewall form. Ian could intensify to a major hurricane within 48 hours.

Tropical Storm Ian will move around the western end of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Ian toward the northwest during the next 36 hours. On its anticipated track Tropical Storm Ian could be near Grand Cayman on Monday morning. Ian could be near western Cuba on Tuesday morning. Ian could be a major hurricane when it approaches western Cuba. Ian will move over the eastern Gulf of Mexico on Wednesday.

Elsewhere over the Atlantic Ocean, Tropical Storm Gaston brought wind and rain to the western Azores and Tropical Depression Hermine was weakening north-northeast of the Cabo Verde Islands.

At 11:00 p.m. EDT on Saturday the center of Tropical Storm Gaston was located at latitude 38.6°N and longitude 33.4°W which put it about 255 miles (410 km) west of the Faial, Azores. Gaston was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 9979 mb.

Tropical Storm Warnings were in effect for Corvo, and Flores.

At 11:00 p.m. EDT on Saturday the center of Tropical Depression Hermine was located at latitude 22.9°N and longitude 20.3°W which put it about 535 miles (860 km) north-northeast of the Cabo Verde Islands. Hermine was moving toward the north at 10 m.p.h. (16 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.

Hurricane Fiona Nears Canadian Maritimes

Hurricane Fiona neared the Canadian Maritimes on Friday night. At 11:00 p.m. EDT on Friday the center of Hurricane Fiona was located at latitude 44.5°N and longitude 60.8°W which put it about 140 miles (220 km) east of Halifax, Nova Scotia. Fiona was moving toward the north at 46 m.p.h. (74 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 933 mb.

A Hurricane Warning was in effect for the portion of the coast from Hubbards to Brule, Nova Scotia. Hurricane Warnings were in effect for Prince Edward Islands and Isle de la Madeline. A Hurricane Warning was in effect for the portion of the coast from Parson’s Pond to Francois, Newfoundland. A Tropical Storm Warning was in effect for St. Andrews, New Brunswick to Hubbards, Nova Scotia. A Tropical Storm Warning was in effect for the portion of the coast from Brule, Nova Scotia to Cap Madeline, Quebec. Tropical Storm Warnings were in effect for Anticosti Island and for the portion of the coast from Sheldrake, Quebec to Parson’s Pond, Newfoundland. A Tropical Storm Warning was in effect for the portion of the coast from Boat Harbor to Hare Bay, Newfoundland. A Tropical Storm Warning was in effect for the portion of the coast from Francois to St. Lawrence, Newfoundland. A Tropical Storm Watch was in effect for the portion of the coast from Boat Harbor, Newfoundland to West Bay, Labrador.

Hurricane Fiona was making a rapid transition to a large, powerful extratropical cyclone on Friday night. The former eye and eyewall were no longer present at the center of Fiona. Most of the remaining thunderstorms were in bands northeast of the center of Fiona’s circulation. Cooler drier air was wrapping around the western and southern sides of the circulation. Upper level divergence above Hurricane Fiona was still pumping mass away and the surface pressure remained around 933 mb.

Hurricane Fiona grew much larger during the transition to an extratropical cyclone. Winds to hurricane force extended out 185 miles (295 km) from the center of Fiona’s circulation. Winds to tropical storm force extended out 345 miles (555 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Fiona was 17.8. The Hurricane Size Index (HSI) was 48.4 and the Hurricane Wind Intensity Size Index (HWISI) was 66.2. Hurricane Fiona was capable of causing extensive serious damage.

An upper level trough over eastern Canada will steer Hurricane Fiona quickly toward the north during the weekend. The strongest winds will occur over eastern Nova Scotia and western Newfoundland. Strong winds will also affect the rest of Nova Scotia and Newfoundland, Prince Edward Island, parts of New Brunswick, Quebec and Labrador. The large circulation around Hurricane Fiona could cause widespread electrical outages. Locally heavy rain could cause floods in some places. Large waves and a storm surge could cause damage along the coast.

Elsewhere over the Atlantic Ocean, Tropical Storm Gaston brought wind and rain to the Azores, Tropical Storm Hermine moved northeast of the Cabo Verde Islands and Tropical Storm Ian formed over the Caribbean Sea.

At 11:00 p.m. EDT on Friday the center of Tropical Storm Gaston was located at latitude 38.9°N and longitude 29.5°W which put it about 50 miles (80 km) west-northwest of the Faial, Azores. Gaston was moving toward the southwest at 8 m.p.h. (13 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 1005 mb.

Hurricane Watches were in effect for the Cayman Islands including Grand Cayman, Little Cayman and Cayman Brac. A Tropical Storm Watch was in effect for Jamaica.

Tropical Depression Ida Brings Rain and Storms to Southeast U.S.

Tropical Depression Ida brought rain and thunderstorms to the southeast U.S. on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Depression Ida was located at latitude 32.6°N and longitude 90.3°W which put it about 20 miles (30 km) north-northwest of Jackson, Mississippi. Ida was moving toward the north-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 999 mb.

Former Hurricane Ida weakened to a tropical depression over Mississippi on Monday afternoon. Even though the speed of the wind circulating around Ida decreased, Tropical Depression Ida was still dropping locally heavy rain and generating a few tornadoes over the southeast U.S. Thunderstorms in bands on the eastern side of Ida were dropping locally heavy rain over parts of Mississippi, Alabama, northwest Florida and northwestern Georgia. Flash Flood Watches were in effect for all of those places. Tornadoes were reported in southeastern Mississippi, and southwestern and central Alabama.

Electricity was still out in all of New Orleans. Southerly winds blowing around the eastern side of Tropical Depression Ida’s circulation were still pushing water toward the coast. Those winds were blowing to near tropical storm force in some locations. A weather station at Fort Morgan, Alabama was reporting a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 47 m.p.h. (76 km/h). The water levels had decreased along the coast, but the persistent southerly winds were preventing the water levels from returning to normal. The water levels should continue to decrease when Tropical Depression Ida moves farther away from the coast.

Tropical Depression Ida will move northeast during the next 72 hours. The center of Ida will cross Tennessee on Tuesday. Ida could be over West Virginia on Wednesday and it could reach the east coast of the U.S. on Thursday. Tropical Depression Ida will continue to drop locally heavy rain over the eastern U.S. The circulation around Ida will interact with a cold front moving slowly south toward the Ohio River. The interaction between Ida and the cold front could enhance rainfall over the Tennessee and Ohio River Valleys. Flash Flood Watches are in effect across the region from Tennessee to New Jersey.

Elsewhere over the Atlantic Ocean, Tropical Storm Julian made a transition to an extratropical cyclone west of the Azores on Monday morning and Tropical Storm Kate developed east-northeast of the Leeward Islands. At 5:00 p.m. EDT on Monday the center of Tropical Storm Ida was located at latitude 22.7°N and longitude 50.9°W which put it about 805 miles (1295 km) east-northeast of the Leeward Islands. Kate was moving toward the north at 10 m.p.h. (16 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 1006 mb.

Tropical Storm Karen Drops Heavy Rain on Puerto Rico and the Virgin Islands

Tropical Storm Karen dropped heavy rain on parts of Puerto Rico and the Virgin Islands on Tuesday.  At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Karen was located at latitude 17.5°N and longitude 66.0°W which put it about 65 miles (105 km) south of San Juan Puerto Rico.  Karen was moving toward the north at 8 m.p.h. (13 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 1005 mb.

Tropical Storm Warnings were in effect for Puerto Rico including Vieques and Culebra, the U.S. Virgin Islands and the British Virgin Islands.

The circulation around Tropical Storm Karen exhibited more organization on Tuesday afternoon.  A new low level center of circulation formed a little farther to the west near a cluster of stronger thunderstorms.  The minimum surface pressure decreased by several millibars.  More thunderstorms formed near the center of circulation and in bands revolving around the center.  Storms near the newly reformed center of circulation were generating more upper level divergence which was pumping mass away from the tropical storm.  The removal of mass was what allowed the surface pressure to decrease.  Winds to tropical storm force extended out about 80 miles (130 km) from the center of circulation.

Tropical Storm Karen will move through an environment favorable for intensification during the next 24 to 48 hours.  Karen will move over water where the Sea Surface Temperature is near 29°C.  Karen has moved under the middle of an upper level ridge over the eastern Caribbean Sea where the upper level winds are weaker.  There will be less vertical wind shear during the next day or two.  The environment around Tropical Storm Karen will support intensification.  However, the center of Karen will pass over Puerto Rico during the next 24 hours.  The mountains in Puerto Rico will disrupt the circulation in the lower levels and Tropical Storm Karen will weaken when it passes over those mountains.  Karen will likely strengthen again when it moves north of Puerto Rico.

Tropical Storm Karen will move around the western end of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Karen toward the north during the next day or two.  On its anticipated track Tropical Storm Karen will move across Puerto Rico during the next 24 hours.  Karen will drop heavy rain on parts of Puerto Rico, the U.S. Virgin Islands and the British Virgin Islands.  Prolonged heavy rain will create a high risk for flash floods in those areas.

Elsewhere over the Atlantic Ocean, Tropical Storm Jerry was moving slowly toward Bermuda and Tropical Storm Lorenzo was strengthening west of the Cabo Verde Islands.  At 2:00 p.m. EDT the center of Tropical Storm Jerry was located at latitude 30.9°N and longitude 69.1°W which put it about 270 miles (435 km) west-southwest of Bermuda.  Jerry was moving toward the north-northeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 992 mb.  A Tropical Storm Warning was in effect for Bermuda.

At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Lorenzo was located at latitude 12.4°N and longitude 29.3°W which put it about 270 miles (435 km) west-southwest of the Cabo Verde Islands.  Lorenzo was moving toward the west-northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 997 mb

Tropical Storm Karen Develops Near Windward Islands

Tropical Storm Karen developed near the Windward Islands on Sunday morning.  At 8:00 a.m. EDT on Sunday the center of Tropical Storm Karen was located at latitude 11.9°N and longitude 60.9°W which put it about 55 miles (90 km) east-southeast of Grenada.  Karen was moving toward the west-northwest at 9 m.p.h. (15 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 1005 mb.

Tropical Storm Warnings were in effect for Trinidad and Tobago, Grenada, and for St. Vincent and the Grenadines.

A center of circulation developed in an area of thunderstorms east of the axis of a strong tropical wave near the Windward Islands on Sunday morning and the National Hurricane Center designated the system as Tropical Storm Karen.  The strongest thunderstorms were forming in bands south and west of the center of circulation.  Bands north and west of the center consisted primarily of showers and lower clouds.   Winds to tropical storm force extended out about 125 miles (200 km) on the eastern side of the tropical storm.

An upper level trough northeast of the Lesser Antilles was producing strong westerly winds which were blowing across the northern side of Tropical Storm Karen.  An upper level ridge over the Caribbean Sea was producing strong northeasterly winds which were blowing across the western part of Karen.  The upper level winds were causing moderate vertical wind shear which was inhibiting the development of thunderstorms in those parts of Tropical Storm Karen.  The center of circulation developed in a region between the stronger upper level westerly and northeasterly winds.  Most of the thunderstorms were forming in that area where the upper level winds were not as strong.

Tropical Storm Karen will move through an environment that will be only marginally favorable for intensification during the next day or two.  Karen will move over water where the Sea Surface Temperature  is near 29°C.  However, the upper level trough and upper level ridge will continue to cause moderate vertical wind shear.  If Tropical Storm Karen remains in the zone where the upper level winds are not as strong, it could strengthen.  However, if Karen moves under stronger upper level winds, it could weaken to a depression.  Tropical Storm Karen is forecast to move closer to the center of the upper level ridge in two or three days.  If that happens, then the upper level winds will be weaker and Karen could intensify.

Tropical Storm Karen will move around the western end of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Karen toward the west-northwest during the next 12 hours.  Karen will move more toward the north when reaches the end of the ridge.  On its anticipated track Tropical Storm Karen will move across the Windward Islands on Sunday.  Karen will bring gusty winds and locally heavy rain.  Flash floods are likely.  Tropical Storm Karen could approach Puerto Rico and the Virgin Islands on Tuesday.  Tropical Storm Watches are likely to be issued for those islands.

Elsewhere over the Atlantic Ocean Tropical Storm Jerry was spinning south of Bermuda.  At 5:00 a.m. EDT on Sunday the center of Tropical Storm Jerry was located at latitude 25.0°N and longitude 66.9°W which put it about 520 miles (835 km) south-southwest of Bermuda.  Jerry was moving toward the north-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 1002 mb.

Strong Tropical Wave Brings Wind and Rain to Windward Islands

A strong tropical wave was bringing wind and rain to the Windward Islands.  At 8:00 p.m. EDT on Saturday the center of the tropical wave was located at latitude 11.9°N and longitude 59.5°W which put it about 75 miles (120 km) northeast of Tobago.  The wave was moving toward the west at 20 m.p.h. (32 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 axis of the tropical wave stretched from near Barbados to just east of Trinidad and Tobago.  More thunderstorms developed near the axis of the wave on Saturday night and there were indications that a center of circulation could be forming northeast of Trinidad and Tobago.  There were winds to near tropical storm force.  The National Hurricane Center issued a special Tropical Weather Outlook on Saturday night and indicated that tropical storm watches and warnings might need to be issued on Sunday.  The wave is forecast to move over the Windward Islands and into the eastern Caribbean Sea on Sunday.

Elsewhere over the Atlantic Ocean, Tropical Storm Jerry was located north of Puerto Rico.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Jerry was location at latitude 24.1°N and longitude 66.3°W which put it about 575 miles (925 km) south of Bermuda.  Jerry was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 1002 mb.

Hurricane Jerry Passing North of Leeward Islands

Hurricane Jerry was passing north of the Leeward Islands on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Hurricane Jerry was located at latitude 19.6°N and longitude 62.0°W which put it about 120 miles (195 km) northeast of Anguilla.  Jerry was moving toward the west-northwest at 18 m.p.h. (30 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 991 mb.

Tropical Storm Watches were in effect for St. Maarten, St. Martin and St. Barthelemy.

Hurricane Jerry weakened during much of Friday, but it began to exhibited greater organization again late in the afternoon.  Thunderstorms weakened around the core of Jerry and in the rainbands on Friday morning.  The lack of stronger thunderstorms to transport stronger winds to the surface caused the circulation around the hurricane to weaken.  Northwesterly winds blowing around the eastern side of an upper level ridge over the Caribbean Sea caused more vertical wind shear.  The circulation may have also draw some drier air into the western half of the circulation.  Stronger thunderstorms began to redevelop near the center of circulation late in the afternoon.  Thunderstorms also began to form in a band on the western side of Hurricane Jerry.  The circulation around Jerry was small.  Winds to hurricane force extended out 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out about 90 miles (145 km) from the center.

Hurricane Jerry will move through an environment somewhat favorable for intensification during the weekend.  Jerry will move over water where the Sea Surface Temperature is near 28°C.  It will move near the eastern side of an upper level ridge and the ridge will cause some vertical wind shear.  If the shear is greater, the Hurricane Jerry could weaken to a tropical storm.  If the shear is less then Hurricane Jerry could intensify.  It is possible that the wind speed in Hurricane Jerry will fluctuate during the weekend as the strength of the upper level wind changes.

Hurricane Jerry will move south of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Jerry toward the west-northwest during the next 12 to 24 hours.  A portion of the high is forecast to weaken during the weekend and if that happens, then Hurricane Jerry could move northward.  On its anticipated track Hurricane Jerry will pass north of the Leeward Islands and Puerto Rico.

Imelda’s Remnants Cause Flash Floods in Southeast Texas

The remnants of former Tropical Storm Imelda caused flash floods over parts of southeastern Texas on Thursday.  The National Weather Service extended Flash Flood Emergencies for portions of southwestern San Jacinto County, east central Montgomery County, Chambers County and Liberty County.

At 11:00 a.m. EDT on Thursday the center of Tropical Depression Imelda was located at latitude 30.5°N and longitude 95.5°W which put it about 55 miles (90 km) north of Houston, Texas.  Imelda was moving toward the northwest at 6 m.p.h. (9 km/h).  The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1009 mb.

The remnants of former Tropical Storm Imelda remained nearly stationary over southeastern Texas on Thursday morning.  Bands of showers and thunderstorms in the eastern half of the circulation were dropping heavy rain.  There were unofficial reports that some locations had received up to 30 inches (0.9 meters) of rain.  Flash flood were occurring and a portion of Interstate 10 was closed due to high water.  Southeasterly winds were transport very moist air over the region and the heavy rain was forecast to continue.

Elsewhere over the Atlantic Ocean, former Tropical Storm Jerry strengthened into a hurricane and Hurricane Humberto sped away from Bermuda.  At 11:00 a.m. EDT on Thursday the center of Hurricane Jerry was located at latitude 16.8°N and longitude 54.4°W which put it about 490 miles (785 km) east of the Leeward Islands.  Jerry was moving toward the west-northwest at 16 m.p.h. (26 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 988 mb.  Tropical Storm Watches were in effect for St. Maarten, St. Martin, St. Barthelemy, Barbuda, Anguilla, Saba and St. Eustatius.

At 11:00 a.m. EDT on Thursday the center of Hurricane Humberto was located at latitude 36.8°N and longitude 60.0°W which put it about 415 miles (665 km) northeast of Bermuda.  Humberto was moving toward the northeast at 24 m.p.h. (39 km/h).  The maximum sustained wind speed was 110 m.p.h. (185 km/h) and there were gusts to 130 m.p.h. (210 km/h).  The minimum surface pressure was 955 mb.

Hurricane Humberto Brings Strong Winds to Bermuda

Hurricane Humberto brought strong winds to Bermuda on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Humberto was located at latitude 34.0°N and longitude 63.9°W which put it about 130 miles (215 km) northeast of Bermuda.  Humberto was moving toward the northeast at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (225 km/h).  The minimum surface pressure was 952 mb.

The Hurricane Warning for Bermuda was changed to a Tropical Storm Warning because Hurricane Humberto was moving rapidly away from Bermuda.

Although the center of Hurricane Humberto passed just to the northwest of Bermuda, Humberto did produce hurricane force winds on Bermuda.  The weather station at the L.F. Wade International airport measured a sustained wind speed of 82 m.p.h. (132 km/h) and a wind gust to 114 m.p.h. (184 km/h).  There were reports of power electrical outages and wind damage on Bermuda.  Conditions will improve on Thursday when Hurricane Humberto moves rapidly away from Bermuda.

A trough over the eastern U.S. will steer Hurricane Humberto rapidly toward the northeast on Thursday.  Humberto will move into a less favorable environment.  The upper level trough will cause moderate vertical wind shear.  Hurricane Humberto will start to move over cooler water.  Moderate shear and cooler water will cause Hurricane Humberto to weaken during the next several days.  While Humberto moves into a less tropical environment, it will make a transition to a strong extratropical cyclone.

Elsewhere, Tropical Depression Imelda continued to drop heavy rain over parts of eastern Texas and southwestern Louisiana and Tropical Storm Jerry threatened the northern Leeward Islands.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Imelda was located at latitude 31.2°N and longitude 94.9°W which put it about 110 miles (175 km) north-northeast of Houston, Texas.  Imelda was moving toward the north at 3 m.p.h. (5 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 1008 mb.

At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Jerry was located at latitude 15.4°N and longitude 51.8°W which put it about 675 miles (1085 km) east of the Leeward Islands.  Jerry was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 997 mb.  Tropical Storm Watches were in effect for St. Maarten, St. Martin, St. Barthelemy, Barbuda, Anguilla, Saba and St. Eustatius.
