Tropical Storm Debby Moves Inland

Tropical Storm Debby moved inland over the eastern U.S. on Thursday morning.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Debby was located at latitude 34.8°N and longitude 80.2°W which put the center about 55 miles (90 km) east-southeast of Charlotte, North Carolina.  Debby was moving toward the north-northwest 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 997 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Surf City to Ocracoke Inlet, North Carolina.

Tropical Storm Debby weakened gradually as it moved inland over South Carolina on Thursday morning.  The strongest winds were in bands in the part of Tropical Storm Debby that was still over the Atlantic Ocean.  Winds to tropical storm force extended out 195 miles (315 km) east of the center of Debby’s circulation.  The winds were blowing at less than tropical storm force in the parts of Debby that were over land.

Bands of thunderstorms in the northern and eastern parts of Tropical Storm Debby were dropping heavy rain over eastern North Carolina and southern Virginia.  Flood Warnings were in effect for many counties in eastern North Carolina.

The Lumber River at Lumberton, North Carolina was at 17.73 feet (5.40 meters) which was in the Moderate Flood range.  The river was still rising.  The Rock River near Norwood, North Carolina was at 26.73 feet (8.15 meters) which was in the Minor Flood range.  The river was still rising.  The Little River at Manchester, North Carolina was at 23.46 feet (7.15 meters) which is in the Moderate Flood range.  The river was still rising.  The Little Pee Dee River near Galivants Ferry, South Carolina was at 9.25 feet (2.82 meters) which is in the Minor Flood range.  The river was still rising.

An upper level trough approaching the Great Lakes will steer Tropical Storm Debby more quickly toward the northeast during the next 24 hours.  Debby will weaken to a tropical depression during the next few hours.  Even though the wind speeds will decrease further, Tropical Storm Debby will continue to drop heavy rain on the eastern side of the Appalachian Mountains.  Heavy rain is likely to cause floods in additional locations.

Flood Watches are in effect for North Carolina, Virginia, eastern West Virginia, central Pennsylvania, central and northeastern New York, northern Vermont, and northern New Hampshire.

Larry Strengthens to a Hurricane

Former Tropical Storm Larry strengthened to a hurricane over the eastern Atlantic Ocean early on Thursday. At 5:00 a.m. EDT on Thursday the center of Hurricane Larry was located at latitude 13.0°N and longitude 32.3°W which put it about 545 miles (875 km) west-southwest of the Cabo Verde Islands. Larry was moving toward the west at 20 m.p.h. (32 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 987 mb.

Former Tropical Storm Larry intensified quickly during the past 24 hours and it reached hurricane intensity early on Thursday morning. The inner end of a rainband wrapped around the center of Hurricane Larry and an eye appeared intermittently on visible and microwave satellite images. Bands of showers and thunderstorms were revolving around the center of Larry. Storms near the center generated upper level divergence that pumped mass away to the west of the hurricane. Winds to hurricane force extended out 20 miles (30 km) from the center of Larry. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Hurricane Larry will move through an environment favorable for intensification during the next several days. Larry will move over water where the Sea Surface Temperature is near 27.5˚C. It will move under the southern side of an upper level ridge over the eastern Atlantic Ocean. The ridge will produce easterly winds that will blow toward the top of Larry’s circulation. Those winds will cause some vertical wind shear. The winds in the lower levels will also blow from the east and so there will not be a lot of vertical wind shear. Hurricane Larry will strengthen during the next 48 hours and it could intensify to a major hurricane. Hurricane could undergo a period of rapid intensification once an inner core with an eye and an eyewall are fully formed.

Hurricane Larry will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high will steer Larry toward the west during the next several days. On its anticipated track Hurricane Larry will move farther away from the Cabo Verde islands. Larry could be east of the northern Leeward Islands by the weekend.

Elsewhere, the remnants of former Hurricane Ida interacted with a slow moving cold front to cause widespread urban and flash floods in the northeastern U.S. At 5:00 a.m. EDT on Thursday the center of the remnants of former Hurricane Ida was located at latitude 41.4°N and longitude 71.6°W which put it about 40 miles (65 km) southwest of Providence, Rhode Island. Ida was moving toward the northeast at 28 m.p.h. (43 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 998 mb. There were reports of urban and flash floods in central and eastern Pennsylvania, northern New Jersey and southeastern New York including New York City. There were reports of tornadoes in Maryland and New Jersey.

Tropical Storm Henri Brings Wind and Rain to Northeast U.S.

Tropical Storm Henri brought wind and rain to the northeast U.S. on Sunday. At 2:00 p.m. EDT on Sunday the center of Tropical Storm Henri was located at latitude 41.4°N and longitude 71.8°W which put it about 5 miles (10 km) north of Westerly, Rhode Island. Henri was moving toward the northwest at 9 m.p.h. (15 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 991 mb. Tropical storm force winds extended out 130 miles on the eastern side of Henri. Tropical Storm force winds extended out 80 miles in the western half of the circulation.

A Tropical Storm Warning was in effect for the portion of the coast from East Rockaway Inlet, New York to Chatham, Massachusetts. The Tropical Storm Warning included all of Long Island, Block Island, Martha’s Vineyard and Nantucket.

Former Hurricane Henri weakened back to a tropical storm on Sunday morning when it moved over cooler water north of the Gulf Stream. Even though it was weaker, Tropical Storm Henri was producing gusty winds along the coast. A weather station on Block Island, Rhode Island reported a sustained wind speed of 52 m.p.h. (84 km/h) and a wind gust to 65 m.p.h. (105 km/h). A weather station at Point Judith, Rhode Island reported a sustained wind speed of 51 m.p.h. (82 km/h) and a wind gust to 69 m.p.h. (111 km/h). A NOAA C-MAN station at Buzzards Bay, Massachusetts reported a sustained wind speed of 49 m.p.h. (79 km/h) and a wind gust to 57 m.p.h. (92 km/h). The gusty winds were causing scattered power outages in southern New England.

Tropical Storm Henri was also dropping heavy rain over parts of the northeastern U.S. Flash Flood Watches were in effect for northeastern Pennsylvania, southeastern New York and southern New England.

Tropical Storm Henri will move slowly toward the northwest during the rest of Sunday. The westerly winds in the middle latitudes will begin to steer Henri toward the east-northeast on Monday. Tropical Storm Henri will continue to weaken as it moves inland over southern New England. Henri will continue to drop heavy rain on some locations and the risk of flash floods will continue into early next week.

Hurricane Henri Moves Toward Long Island

Hurricane Henri moved toward Long Island on Saturday night. At 11:00 p.m. EDT on Saturday the center of Hurricane Henri was located at latitude 38.6°N and longitude 71.0°W which put it about 180 miles (290 km) south-southeast of Montauk Point, New York. Henri was moving toward the north at 11 m.p.h. (22 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 987 mb.

A Hurricane Warning was in effect for eastern Long Island from Fire Island Inlet to Port Jefferson Harbor. A Hurricane Warning was also in effect for the portion of the coast from New Haven, Connecticut to Westport, Massachusetts. The Hurricane Warning included Block Island. A Tropical Storm Warning was in effect for the south coast of Long Island from East Rockaway Inlet to Fire Island Inlet. A Tropical Storm Warning was in effect for the north coast of Long Island from East Rockaway Inlet to Port Jefferson, Harbor. A Tropical Storm Warning was in effect for the portion of the coast from East Rockaway Inlet to New Haven, Connecticut. A Tropical Storm Warning was in effect from the portion of the coast from Westport, Massachusetts to Chatham, Massachusetts. The Tropical Storm Warning included Nantucket and Martha’s Vineyard. A Tropical Storm Warning was also in effect for the portion of the coast from East Rockaway Inlet, New York to Manasquan Inlet, New Jersey. The Tropical Storm Warning included New York City.

Hurricane Henri exhibited more organization on Saturday night but reconnaissance flights were not finding an increase in the wind speeds. A circular eye with a diameter of 30 miles (50 km) formed at the center of Henri. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring. Bands of showers and thunderstorms were revolving around the core of Henri. Storms near the core generated upper level divergence that pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease slowly on Saturday. Winds to hurricane force extended out 35 miles in the southeastern quadrant of Henri. The winds in the other parts of Henri were blowing at less than hurricane force. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Hurricane Henri will move through an environment favorable for intensification during the next few hours. Henri will move over the Gulf Stream where the Sea Surface Temperatures are near 29°C. It will move around the eastern side of an upper level trough over the eastern U.S. The trough will produce southerly winds that will blow toward the top of Henri’s circulation. Those winds will cause some vertical wind shear, but the shear may not be enough to prevent some intensification during the next few hours. Hurricane Henri could strengthen during the next 6 hours. Henri will move over cooler water when it moves north of the Gulf Stream on Sunday and that will cause it to weaken. Some drier air could wrap around the western and southern sides of Hurricane Henri on Sunday.

The upper level trough will steer Hurricane Henri toward the north-northwest on Sunday. On its anticipated track Hurricane Henri will approach Long Island during the middle of the day on Sunday. Henri could still be a hurricane when it nears Long Island. Hurricane Henri is likely to cause minor wind damage on Long Island and in southern New England. Gusty winds and falling trees could cause widespread power outages. Henri could move more slowly when it moves across southern New England. Locally heavy rain over a prolonged period could cause flash floods. Hurricane Henri could cause a storm surge of up to 4 to 7 feet (1 to 2 meters) where the wind blows the water toward the coast.

Henri Strengthens to a Hurricane

Former Tropical Storm Henri strengthened to a hurricane on Saturday morning. At 11:00 a.m. EDT on Saturday the center of Hurricane Henri was located at latitude 34.4°N and longitude 72.5°W which put it about 180 miles (290 km) east-southeast of Cape Hatteras, North Carolina. Henri was moving toward the north-northeast at 14 m.p.h. (22 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 991 mb.

A Hurricane Warning was in effect for eastern Long Island from Fire Island Inlet to Port Jefferson Harbor. A Hurricane Warning was also in effect for the portion of the coast from New Haven, Connecticut to Westport, Massachusetts. The Hurricane Warning included Block Island. A Tropical Storm Warning was in effect for the south coast of Long Island from East Rockaway Inlet to Fire Island Inlet. A Tropical Storm Warning was in effect for the north coast of Long Island from East Rockaway Inlet to Port Jefferson, Harbor. A Tropical Storm Warning was in effect for the portion of the coast from East Rockaway Inlet to New Haven, Connecticut. A Tropical Storm Warning was in effect from the portion of the coast from Westport, Massachusetts to Chatham, Massachusetts. The Tropical Storm Warning included Nantucket and Martha’s Vineyard. A Tropical Storm Warning was also in effect for the portion of the coast from East Rockaway Inlet, New York to Manasquan Inlet, New Jersey. The Tropical Storm Warning included New York City.

Reconnaissance planes found that former Tropical Storm Henri has strengthened to a hurricane on Saturday morning. More thunderstorms formed near the center of Henri and the inner end of a rainband wrapped around the north side of the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease. Winds to hurricane force extended out 60 miles in the southeastern quadrant of Henri. The winds in the other parts of the storm were blowing at less than hurricane force. Winds to tropical storm for extended out 130 miles (210 km) from the center of circulation.

Hurricane Henri will move through an environment favorable for intensification during the next 18 hours. Henri will move over the Gulf Stream where the Sea Surface Temperatures are near 29°C. It will move around the eastern side of an upper level trough over the eastern U.S. The trough will produce southwesterly winds that will blow toward the top of Henri’s circulation. Those winds will cause some vertical wind shear, but the shear will not be enough to prevent intensification. Hurricane Henri is likely to strengthen during the next 12 hours. Henri will move over cooler water when it moves north of the Gulf Stream on Sunday and that will cause it to weaken.

The upper level trough will steer Hurricane Henri toward the north-northeast during the next 12 hours. The position and orientation of the trough will change as it interacts with Hurricane Henri. The trough will pull Henri toward the north-northwest on Sunday. On its anticipated track Hurricane Henri will approach Long Island on Sunday afternoon. Henri could be a hurricane when it nears Long Island. Hurricane Henri is likely to cause minor wind damage on Long Island and in southern New England. Gusty winds and falling trees could cause widespread power outages. Henri could move slowly when it moves across southern New England. Locally heavy rain could cause flash floods. Hurricane Henri could cause a storm surge of up to 4 to 7 feet (1 to 2 meters) where the wind blows the water toward the coast.

Elsewhere, Tropical Storm Grace was dropping heavy rain over parts of central Mexico. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Grace was located at latitude 19.7°N and longitude 98.9°W which put it about 25 miles (40 km) north-northeast of Mexico City, Mexico. Grace was moving toward the west-southwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 990 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Puerto Veracruz to Barra de Tordo, Mexico.

Grace Rapidly Intensifies to a Major Hurricane

Hurricane Grace rapidly intensified to a major hurricane near Mexico on Friday night. At 11:00 p.m. EDT on Friday the center of Hurricane Grace was located at latitude 20.7°N and longitude 96.3°W which put it about 75 miles (120 km) east-southeast of Tuxpan, Mexico. Grace was moving toward the west at 10 m.p.h. (16 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. (220 km/h). The minimum surface pressure was 967 mb.

A Hurricane Warning was in effect for the portion of the coast from Puerto Veracuz to Cabo Rojo, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Cabo Rojo to Barra del Tordo, Mexico.

Hurricane Grace rapidly intensified to a major hurricane on Friday night. A circular eye with a diameter of 35 miles (55 km) was at the center of Grace. The eye was surround by a 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 Grace. Storms near the core generated upper level divergence that pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease, which produced a rapid increase in the surface wind speed.

Hurricane Grace was an average sized hurricane. Winds to hurricane force extended out 30 miles (50 km) from the center of Grace. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation. The Hurricane Intensity Index (HII) for Grace was 22.1. The Hurricane Size Index (HSI) was 11.2 and the Hurricane Wind Intensity Size Index (HWISI) was 33.3. Hurricane Grace was capable of regional major damage.

Hurricane Grace will move south of a high pressure system that extends over the Gulf of Mexico. The high pressure system will steer Grace toward the west during the next 24 hours. On its anticipated track the center of Hurricane Grace will make landfall on the coast of Mexico between Tuxpan and Veracruz in a few hours. Grace will be capable of causing major wind damage. It will drop locally heavy rain and flash floods are likely. Hurricane Grace could cause a storm surge of up to 10 feet (3 meters) where the wind blows the water toward the coast. Grace will weaken quickly when it moves inland over Mexico, but heavy rain could cause flash floods over parts of Central Mexico,

Elsewhere, Tropical Storm Henri was moving toward the north off the East Coast of the U.S. At 11:00 p.m. EDT on Friday the center of Tropical Storm Henri was located at latitude 32.3°N and longitude 73.5°W which put it about 230 miles (375 km) south-southeast of Cape Hatteras, North Carolina. Henri was moving toward the north at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 70 m.p.h. (85 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 994 mb.

A Hurricane Warning was in effect for eastern Long Island from Fire Island Inlet to Port Jefferson Harbor. A Hurricane Warning was also in effect for the portion of the coast from New Haven, Connecticut to Watch Hill, Rhode Island.

A Tropical Storm Warning was also in effect for the portion of the coast from East Rockaway Inlet, New York to Manasquan Inlet, New Jersey. The Tropical Storm Warning included New York City.

Tropical Storm Henri Prompts Hurricane Watches for Long Island, Southeast New England

A potential threat from Tropical Storm Henri prompted the issuance of Hurricane Watches for parts of Long Island and southeastern New England on Friday morning. At 8:00 a.m. EDT on Friday the center of Tropical Storm Henri was located at latitude 30.0°N and longitude 73.7°W which put it about 375 miles (600 km) southeast of Cape Hatteras, North Carolina. Henri was moving toward the west-northwest at 9 m.p.h. (15 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 995 mb.

A Hurricane Watch was issued for eastern Long Island from Fire Island Inlet to Port Jefferson Harbor. A Hurricane Watch was also issued for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts. The Hurricane Watch included Block Island, Martha’s Vineyard and Nantucket. A Tropical Storm Watch was issued for the south coast of Long Island from East Rockaway Inlet to Fire Island Inlet. A Tropical Storm Watch was issued for the north coast of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Watch was also issued for the portion of the coast from East Rockaway Inlet to New Haven, Connecticut.

Tropical Storm Henri did not change much during Thursday night. The distribution of thunderstorms around Henri remained asymmetrical. The strongest thunderstorms were occurring in bands in the southern half of Henri. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. Henri was moving under the southeastern part of an upper level ridge off the east coast of the U.S. The ridge was producing northeasterly winds that were blowing toward the top of Henri’s circulation. Those winds were causing moderate vertical wind shear and they were also contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 90 miles (145 km) from the center of Henri.

Although Tropical Storm Henri is currently moving toward the west-northwest, an upper level trough over the eastern U.S. will turn Henri toward the north on Friday. The trough will steer Henri toward the north on Saturday. When Henri turns toward the north it will move under the axis of the upper level ridge. The upper level winds are weaker near the axis of the ridge and the wind shear will be less. Tropical Storm Henri is likely to strengthen to a hurricane on Saturday. Henri will move over the warm water in the Gulf Stream and there is a chance that Henri could strengthen to Category 2 on the Saffir-Simpson Scale.

A high pressure system will move northeast of Henri on Sunday. The high pressure system will block Henri and prevent it from moving toward the northeast. The high pressure system will also slow the forward speed of Henri. Henri could be moving slowly when it nears Long Island and southeastern New England. A slow forward speed would increase the time period when places experience strong gusty winds, which would increase the chance for wind damage and power outages. Slow movement would also increase the total rainfall in many locations and the risk for flash floods would increase. Henri could also cause a storm surge of up to 4 to 7 feet (1 to 2 meters) along the coast.

Elsewhere, former Tropical Storm Grace strengthened back to a hurricane over the southwestern Gulf of Mexico on Friday morning. At 8:00 a.m. EDT on Friday the center of Hurricane Grace was located at latitude 20.6°N and longitude 93.7°W which put it about 185 miles (300 km) east-northeast of Veracruz, Mexico. Grace was moving toward the west at 15 m.p.h. (24 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 983 mb.

A Hurricane Warning was in effect for the portion of the coast from Puerto Veracuz to Cabo Rojo, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Cabo Rojo to Barra del Tordo, Mexico.

At 8:00 a.m. EDT on Thursday the center of Hurricane Grace was located at latitude 20.1°N and longitude 87.9°W which put it about 45 miles (65 km) south-southeast of Valladolid, Mexico. Grace was moving toward the west at 17 m.p.h. (28 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 989 mb.

A Hurricane Warning was in effect for the portion of the coast from Cancun to Punta Herrero, Mexico. The Hurricane Warning included Cozumel. A Hurricane Watch was in effect for the portion of the coast from Puerto Veracruz to Cabo Rojo,, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Cancun to Campeche, Mexico and from Punta Herrero to Puerto Costa Maya, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Cabo Rojo to Puerto de Altamira, Mexico. Tropical Storm Watches were also in effect for the Cuban provinces of Isla de la Juventud and Pinar del Rio.

The center of Hurricane Grace made landfall on the east coast of the Yucatan Peninsula southeast of Tulum on Thursday morning. The maximum sustained wind speed was 80 m.p.h. (130 km/h) at the time of landfall. Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Grace. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. Grace will produce strong gusty winds over the Yucatan. It will also drop heavy rain and flash floods are likely to occur. Hurricane Grace will weaken gradually back to a tropical storm while it moves across the Yucatan.

Hurricane Grace will move over the southwestern Gulf of Mexico on Thursday night. Grace will move into an environment favorable for intensification when it moves over the Gulf of Mexico. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move into a region where the upper level winds are weak and there will be little vertical wind shear. Grace is likely to intensify back to a hurricane on Friday.

Hurricane Grace will move south of a subtropical high pressure system that extends over the Gulf of Mexico. The high will steer Grace toward the west during the next several days. On its anticipated track Hurricane Grace will move across the Yucatan Peninsula on Thursday. Grace will move over the southwestern Gulf of Mexico on Thursday night. Hurricane Grace could approach the coast of Mexico between Veracruz and Tampico on Friday night.

Elsewhere, former Tropical Storm Fred was dropping heavy rain over parts of the northeastern U.S. and Tropical Storm Henri was moving west toward the east coast of the U.S.

A Tropical Storm Warning was also in effect for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts including Block Island, Nantucket, Martha’s Vineyard, and Cape Cod.

Tropical Storm Elsa was buffeting the northeastern U.S. with gusty winds and locally heavy rain on Friday morning. The center of Elsa was passing south of Long Island, but rain was falling over an area that extended from New York City to southern Maine. Winds to tropical storm force extended out 150 miles (240 km) to the southeast of the center of Elsa. Winds to tropical storm force also extended out 80 miles (130 km) to the northeast of the center of circulation. Winds in the western half of Tropical Storm Elsa were not as strong. Elsa could cause sporadic power outages and flash floods in the northeastern U.S. on Friday.

Tropical Storm Elsa will make a transition to an extratropical cyclone during the next 24 hours, while it moves quickly toward the northeast. Elsa will move over water where the Sea Surface Temperatures are near 22°C. An upper level trough over the Great Lakes will produce strong southwesterly winds that will blow toward the top of Elsa’s circulation. Those winds will cause strong vertical wind shear. The combination of cooler Sea Surface Temperatures and strong wind shear will cause the structure of Tropical Storm Elsa to change to the structure of an extratropical cyclone. The center of Elsa will pass near Cape Cod on Friday afternoon. Elsa will pass over the Canadian Maritime Provinces on Friday night. It could be near Labrador and eastern Newfoundland on Saturday.

Tropical Storm Elsa Moves over North Carolina

Tropical Storm Elsa moved a little more quickly toward the northeast on Thursday. The surface center of Elsa moved over North Carolina. The structure of Elsa exhibited the typical characteristics of a tropical storm moving northeast near the coast of the U.S. Heavy rain was falling in the northeastern part of Tropical Storm Elsa. The heaviest rain was falling on eastern North Carolina and eastern Virginia. Drier air was wrapping around the western and southern sides of Elsa. The strongest winds were blowing in the southeastern part of Tropical Storm Elsa that was over the Atlantic Ocean.

An upper level trough over the Great Lakes will steer Tropical Storm Elsa quickly toward the northeast during the next 36 hours. On its anticipated track Elsa will move over Virginia on Thursday evening. Tropical Storm Elsa could be near Long Island on Friday morning. Elsa could pass near Cape Cod later on Friday. Tropical Storm Elsa will make a transition to an extratropical cyclone when it moves farther north. Elsa will bring gusty winds and heavy rain to the East Coast of the U.S. from North Carolina to Massachusetts. Tropical Storm Elsa could cause sporadic power outages along the East Coast. Locally heavy rain could cause flash floods in some locations.
