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 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.

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.

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.

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

Tropical Storm Elsa brought wind and rain to the northeast U.S. on Friday morning. At 8:00 p.m. EDT on Friday the center of Tropical Storm Elsa was located at latitude 40.2°N and longitude 73.1°W which put it about 90 miles (145 km) southwest of Montauk Point, New York. Elsa was moving toward the northeast at 31 m.p.h. (50 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 1000 mb.

A Tropical Storm Warning was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. 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 over North Carolina on Thursday. At 2:00 p.m. EDT on Thursday the center of Tropical Storm Elsa was located at latitude 35.6°N and longitude 79.0°W which put it about 25 miles (40 km) west of Raleigh, North Carolina. Elsa was moving toward the northeast at 20 m.p.h. (32 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 1007 mb.

A Tropical Storm Warning was in effect for the portion of the coast from South Santee River, South Carolina to Sandy Hook, New Jersey. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound. A Tropical Storm Warning was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. 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 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.

Tropical Storm Elsa Prompts Warnings for East Coast

Tropical Storm Elsa prompted the issuance of warnings and watches for the East Coast of the U.S. on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Elsa was located at latitude 32.1°N and longitude 82.3°W which put it about 55 miles (90 km) west of Savannah, Georgia. Elsa was moving toward the north-northeast at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 55 m.p.h. (90 km/h). The minimum surface pressure was 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Altamaha Sound, Georgia to Great Egg Inlet, New Jersey. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound. A Tropical Storm Watch was in effect for the portion of the coast from Great Egg Inlet to Sandy Hook, New Jersey. A Tropical Storm Watch was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Watch 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.

The center of Tropical Storm Elsa was moving across eastern Georgia on Wednesday night. Heavy rain was spreading across South Carolina. Rainbands on the eastern side of Elsa’s circulation were producing winds to tropical storm force over the Atlantic Ocean. NOAA buoy 41008 at Grays Reef reported 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 circulation around Tropical Storm Elsa was still well defined. A distinct low pressure system was evident on the surface map, radar and satellite displays. Storms on the eastern side of Elsa generated upper level divergence that pumped mass away to the northeast of the tropical storm.

An upper level trough over the Great Lakes will steer Tropical Storm Elsa toward the northeast during the next 48 hours. On its anticipated track Tropical Storm Elsa will move across South Carolina on Thursday morning and North Carolina on Thursday afternoon. Elsa could be over eastern Virginia on Thursday evening and near Long Island by Friday morning. Even though the center of Tropical Storm Elsa will be over land for another 18 to 24 hours, bands on the eastern side of the circulation could produce tropical storm force winds over the Atlantic Ocean and along the East Coast of the U.S. Elsa will also drop locally heavy rain over South Carolina, eastern North Carolina and eastern Virginia. Gusty winds and heavy rain could cause sporadic power outages. Heavy rain could also cause flash floods in some locations.

Tropical Storm Elsa Makes Landfall in Florida

Tropical Storm Elsa made landfall on the coast of north Florida on Wednesday morning. At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Elsa was located at latitude 29.9°N and longitude 83.6°W which put it about 20 miles (30 km) southwest of Perry, Florida. Elsa was moving toward the north at 14 m.p.h. (22 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 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Aripeka to Ochlockonee River, Florida. A Tropical Storm Warning was also in effect for the portion of the coast from the Mouth of the St. Marys River, Florida to Little River Inlet, South Carolina. A Tropical Storm Watch was in effect for the portion of the coast from Little River Inlet, South Carolina to Sandy Hook New Jersey including Albemarle and Pamlico Sounds.

The center of Tropical Storm Elsa made landfall in Taylor County, Florida about 20 miles southwest of Perry around 11:00 a.m. EDT on Wednesday. Elsa weakened from a hurricane to a strong tropical storm before it made landfall. Bands in the eastern half of the circulation around Tropical Storm Elsa dropped heavy rain over Florida. Rain was beginning to spread over southern Georgia. Gusty winds caused power outages in parts of Florida. Elsa caused a minor storm surge along the west coast of Florida.

Tropical Storm Elsa will weaken steadily during the next 48 hours while the center moves farther inland. Elsa will be steered toward the northeast during the next few days by an upper level trough over the Great Lakes. On its anticipated track Tropical Storm Elsa will move over southern Georgia on Wednesday night. Elsa could be over South Carolina on Thursday morning and it could be over eastern Virginia by Thursday night. Elsa could strengthen back to a tropical storm if the center moves over the Atlantic Ocean later this week.

Tropical Storm Elsa will continue to drop locally heavy rain over northern Florida during the next few hours. Heavy rain will spread over southern Georgia, South Carolina, eastern North Carolina and eastern Virginia. Heavy rain could cause flash floods in some locations. Gusty winds could cause sporadic power outages. There could be enough low level wind shear in stronger rainbands to produce tornadoes. When Tropical Storm Elsa gets closer to the East Coast of the U.S., southeasterly winds will blow water toward the coast. Those winds will cause water levels to rise along the coast

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.

Tropical Storm Isaias Speeds Past New York City

Tropical Storm Isaias sped past New York City on Tuesday afternoon.  At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Isaias was located at latitude 40.9°N and longitude 75.1°W which put it about 65 miles (105 km) west of New York, New York.  Isaias was moving toward the north-northeast at 40 m.p.h. (65 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 994 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Chincoteague, Virginia to Eastport, Maine including Long Island, Long Island Sound, Block Island, Martha’s Vineyard and Nantucket.

Tropical Storm Isaias sped up the East Coast of the U.S. on Tuesday and the center of circulation was west of New York City by Tuesday afternoon.  Isaias was still generating an area of winds to tropical storm force over the Atlantic Ocean.  A NOAA buoy at the entrance to New York Harbor measured a sustained wind speed of 57 m.p.h. (83 km/h) and a wind gust of 71 m.p.h. (115 km/h).  JFK airport recently reported a wind gust to 70 m.p.h. (113 km/h).

The eastern side of former Hurricane Isaias produced strong wind gusts along the East Coast of the U.S. from North Carolina to Long Island.  A station at Federal Point, North Carolina reported a gust of 99 m.p.h.  (160 km/h).  Wrightsville Beach, North Carolina had a wind gust to 86 m.p.h. (139 km/h).  Stevensville, Maryland measured a gust of 79 m.p.h. (127 km/h).  South Norfolk, Virginia reported a wind gust to 76 m.p.h. (122 km/h) and Nags Head, North Carolina had a gust of 75 m.p.h. (120 km/h).  Ocean City, Maryland measured a gust of 69 m.p.h. (111 km/h).

The strong wind gusts caused widespread power outages.  Shear in the lower levels of the atmosphere also contributed to the spinup of a number of tornadoes.  Tropical Storm isaias dropped heavy rain over parts of the northeastern U.S.  Isaias will continue to speed north-northeastward into Canada during the next 12 hours.  Tropical Storm Isaias will gradually weaken and wind speeds should decrease.  Isaias will continue to drop locally heavy rain over eastern New York, western Massachusetts and Vermont for several more hours.  The potential for flash floods in those areas still exists.
