Hurricane Lee Causes Gusty Winds in Bermuda

Hurricane Lee caused gusty winds in Bermuda on Thursday. At 11:00 p.m. EDT on Thursday the center of Hurricane Lee was located at latitude 32.9°N and longitude 67.6°W which put it about 170 miles (275 km) west-northwest of Bermuda. Lee was moving toward the north at 14 m.p.h. (22 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 957 mb.

A Hurricane Watch was in effect for the portion of the coast from Stonington, Maine to the U.S./Canada border. A Hurricane Watch was also in effect for the portion of the coast from the U.S./Canada border to Point Lepreau, New Brunswick. That Hurricane Watch included Grand Manan Island. A Hurricane Watch was in effect for the portion of the coast from Digby to Medway Harbour, Nova Scotia.

A Tropical Storm Warning was in effect for Bermuda. A Tropical Storm Warning was in effect for the portion of the coast from Westport, Massachusetts to the U.S. Canada border. That Tropical Storm Warning included Martha’s Vineyard and Nantucket. A Tropical Storm Warning was in effect for the portion of the coast from the U.S./Canada border to Fort Lawrence, New Brunswick. That Tropical Storm Warning included Grand Manan Island. A Tropical Storm Warning was in effect for the portion of the coast from Fort Lawrence, New Brunswick to Point Tupper, Nova Scotia.

The circulation around the eastern side of Hurricane Lee was producing gusty winds in Bermuda on Thursday night. A weather station at the L.F. Wade International Airport (TXKF) reported a sustained wind speed of 43 m.p.h. (69 km/h) and a wind gust of 62 m.p.h. (100 km/h). The center of Hurricane Lee passed about 75 miles (120 km) east of NOAA buoy 41048 earlier in Thursday. The buoy reported a sustained wind speed of 65 m.p.h. (105 km/h) and a wind gust of 92 m.p.h. (148 km/h).

Hurricane Lee was beginning to exhibit the typical structure of a hurricane moving northward off the east coast of the U.S. There was no longer a well formed eye at the center of Lee’s circulation. Drier air was being pulled around the southern side of Hurricane Lee. An upper level trough over the eastern U.S. was producing southwesterly winds that were blowing toward the top of Lee’s circulation. Those winds were causing moderate vertical wind shear. The effects of the drier air and the vertical wind shear were causing an asymmetrical distribution of thunderstorms in Hurricane Lee. Most of the thunderstorms were occurring in bands in the northern and western sides of Lee’s circulation, Bands in the eastern and southern sides of the circulation consisted primarily of showers and lower clouds.

The changes to the structure of Hurricane Lee produced a large area of tropical storm force winds. Winds to hurricane force extended out 105 miles (165 km) from the center of Lee’s circulation. Winds to tropical storm force extended out 345 miles (555 km) from the center of circulation. The Hurricane Intensity Index (HII) was 12.7. The Hurricane Size Index (HSI) was 37.6 and the Hurricane Wind Intensity Size Index (HWISI) was 50.3. Hurricane Lee was about three-fourths as large as Hurricane Sandy was in 2012.

Hurricane Lee will move through an environment that will be unfavorable for intensification of a hurricane during the next 24 hours. Lee will move over water where the Sea Surface Temperatures are near 27°C. The upper level trough over the eastern U.S. will continue to will cause moderate vertical wind shear. The circulation around Lee will also pull in more drier air. The combination of moderate vertical wind shear and the drier air will cause Hurricane Lee to weaken gradually during the next 24 hours. The combination of vertical wind shear and drier air will also cause Hurricane Lee to make a gradual transition to an extratropical cyclone during the next 48 hours.

Hurricane Lee will move around the western part of a subtropical high pressure system over the Atlantic Ocean. The high pressure system and the upper level trough over the eastern U.S. will steer Lee toward the north during the next 24 hours. On its anticipated track, the center of Hurricane Lee will be southeast of Cape Cod by Friday night. Lee will affect Maine, New Brunswick and Nova Scotia later on Saturday. Hurricane Lee could be in the middle of a transition to an extratropical cyclone on Saturday. Lee will bring strong, gusty winds and locally heavy rain to the coast of the Northeast U.S. and Nova Scotia. Heavy rain could cause flash floods in come locations. The winds blowing around the northern side of Hurricane Lee will push water toward the coast. The water level could rise as much as four feet (one meter) along parts of the coast.

Elsewhere over the Atlantic Ocean, Hurricane Margot was churning west of the Azores. At 11:00 p.m. EDT on Thursday the center of Hurricane Margot was located at latitude 36.9°N and longitude 38.9°W which put it about 655 miles (1055 km) west of the Azores. Margot was moving toward the east-northeast at 3 m.p.h. (5 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 982 mb.

Hurricane Lee Prompts Watches for Northeast U.S.

The risk posed by Hurricane Lee prompted the issuance of a Hurricane Watch and a Tropical Storm Watch for a portion of the Northeast U.S. on Wednesday afternoon. At 5:00 p.m. EDT on Wednesday the center of Hurricane Lee was located at latitude 27.4°N and longitude 67.6°W which put it about 380 miles (610 km) south-southwest of Bermuda. Lee was moving toward the north-northwest at 9 m.p.h. (15 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 952 mb.

A Hurricane Watch was in effect for the portion of the coast from Stonington, Maine to the U.S./Canada border. A Tropical Storm Warning was in effect for Bermuda. A Tropical Storm Watch was in effect for the portion of the coast from Watch Hill, Rhode Island to Stonington, Maine. The Tropical Storm Watch included Block Island, Martha’s Vineyard and Nantucket.

Hurricane Lee weakened a little on Wednesday, but Lee remained a large and powerful hurricane. A circular eye with a diameter of 36 miles (50 km) was at the center of Lee’s circulation. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Hurricane Lee. Storms near the center of Lee’s circulation generated upper level divergence that pumped mass away from the hurricane.

Hurricane Lee was still a very large hurricane. Winds to hurricane force extended out 115 miles (185 km) from the center of Lee’s circulation. Winds to tropical storm force extended out 265 miles (425 km) from the center of circulation. The Hurricane Intensity Index (HII) was 17.8. The Hurricane Size Index (HSI) was 28.2 and the Hurricane Wind Intensity Size Index (HWISI) was 46.0. Hurricane Lee was similar in size and intensity to Hurricane Frances when Frances hit Southeast Florida in 2004.

Hurricane Lee will move through an environment that will become more unfavorable for a major hurricane during the next 24 hours. Lee will move over water where the Sea Surface Temperatures are near 28°C. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Lee’s circulation. Those winds will cause the vertical wind shear to increase on Thursday. Hurricane Lee will move over cooler water later on Thursday. The combination of more vertical wind shear and cooler water will cause Hurricane Lee to weaken gradually during the next 24 hours.

Hurricane Lee will move around the western part of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Lee toward the north during the next 24 hours. On its anticipated track, the center of Hurricane Lee will pass west of Bermuda on Thursday evening. Bands in the eastern side of Lee’s circulation will bring gusty winds and locally heavy rain to Bermuda on Thursday.

Hurricane Lee could be east of Cape Cod by Saturday morning. Lee will affect Maine and Nova Scotia later on Saturday. Hurricane Lee could be in the middle of a transition to an extratropical cyclone on Saturday. Lee will bring strong, gusty winds and locally heavy rain to the coast of the Northeast U.S. and Nova Scotia. Heavy rain could cause flash floods in come locations. The winds blowing around the northern side of Hurricane Lee will push water toward the coast. A Storm Surge Watch has been issued for Cape Cod Bay and Nantucket, Massachusetts.

Elsewhere over the Atlantic Ocean, Hurricane Margot was spinning over the Central Atlantic. At 5:00 p.m. EDT on Wednesday the center of Hurricane Margot was located at latitude 34.7°N and longitude 40.6°W which put it about 790 miles (1270 km) west-southwest of the Azores. Margot was moving toward the north at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 971 mb.

Hurricane Lee Prompts Tropical Storm Watch for Bermuda

The potential effects of Hurricane Lee prompted the issuance of a Tropical Storm Watch for Bermuda on Tuesday. At 5:00 p.m. EDT on Tuesday the center of Hurricane Lee was located at latitude 24.7°N and longitude 66.4°W which put it about 530 miles (860 km) south of Bermuda. Lee was moving toward the northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (215 km/h). The minimum surface pressure was 946 mb.

A Tropical Storm Watch was in effect for Bermuda.

Hurricane Lee completed an eyewall replacement cycle on Tuesday. A large eye with a diameter of 45 miles (75 km) was at the center of Lee’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms revolved around the center of Hurricane Lee. Storms near the center of Lee’s circulation generated upper level divergence that pumped mass away from the hurricane.

The size of the circulation around Hurricane Lee increased on Tuesday after the eyewall replacement cycle. Winds to hurricane force extended out 125 miles (200 km) from the center of Lee’s circulation. Winds to tropical storm force extended out 240 miles (390 km) from the center of circulation. The Hurricane Intensity Index (HII) was 20.6. The Hurricane Size Index (HSI) was 36.2 and the Hurricane Wind Intensity Size Index (HWISI) was 56.8. Hurricane Lee was similar in size and intensity to Hurricane Ivan when Ivan hit the Gulf Coast in 2004.

Hurricane Lee will move through an environment that will be favorable for intensification during the next 24 hours. Lee will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. The large size of the circulation around Hurricane Lee could limit changes of intensity during the next 24 hours. Lee could intensify a little on Wednesday. An upper level trough over the Great Lakes will cause the vertical wind shear to increase later this week.

Hurricane Lee will move around the western part of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Lee toward the north-northwest during the next 24 hours. On its anticipated track, Hurricane Lee will move south-southwest of Bermuda on Wednesday.

Elsewhere over the Atlantic Ocean, Hurricane Margot moved north over the Central Atlantic. At 5:00 p.m. EDT on Tuesday the center of Hurricane Margot was located at latitude 31.7°N and longitude 39.6°W which put it about 835 miles (1345 km) west-southwest of the Azores. Margot was moving toward the north at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 977 mb.

Hurricane Lee Moves South of Bermuda

Hurricane Lee moved south of Bermuda on Monday. At 11:00 p.m. EDT on Monday the center of Hurricane Lee was located at latitude 23.9°N and longitude 64.8°W which put it about 580 miles (935 km) south of Bermuda. Lee was moving toward the west-northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (215 km/h). The minimum surface pressure was 948 mb.

Hurricane Lee went through another eyewall replacement cycle on Monday. The inner end of a rainband wrapped around the existing eye and eyewall early on Monday. Two concentric eyewalls were present at the core of Lee’s circulation during much of Monday. The inner eyewall weakened throughout the day, but a portion of the inner eyewall was still present on microwave satellite images on Monday evening. Low level convergence became concentrated into the outer eyewall and the outer eyewall began to contract around the center of Hurricane Lee. Bands of showers and thunderstorms revolved around the concentric eyewalls. Storms near the core of Lee’s circulation generated upper level divergence that pumped mass away from the hurricane.

The eyewall replacement cycle caused some fluctuations in the size and intensity of Hurricane Lee on Monday. Winds to hurricane force extended out 80 miles (130 km) from the center of Lee’s circulation. Winds to tropical storm force extended out 185 miles (295 km) from the center of circulation. The Hurricane Intensity Index (HII) was 20.6. The Hurricane Size Index (HSI) was 26.4 and the Hurricane Wind Intensity Size Index (HWISI) was 47.0. Hurricane Lee was similar in size and intensity to Hurricane Irma when Irma hit Southwest Florida in 2017.

Hurricane Lee will move through an environment that will be favorable for intensification during the next 24 hours. Lee will move over water where the Sea Surface Temperatures are near 29°C. It will move into a region where the upper level winds are weak and there will be little vertical wind shear. If the inner eyewall dissipates completely, then Hurricane Lee could intensify on Tuesday.

Hurricane Lee will move around the southwestern part of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Lee toward the northwest during the next 24 hours. On its anticipated track, Hurricane Lee will be far to the south of Bermuda on Tuesday.

A Tropical Storm Warning was in effect for the portion of the coast from Surf City, North Carolina to the North Carolina/Virginia border. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound.

Tropical Storm Idalia was moving quickly away from North Carolina on Thursday afternoon. An upper level trough over the east coast of the U.S. was producing strong westerly winds that were blowing across the top of Idalia’s circulation. Those winds were causing strong vertical wind shear and they were blew the top of Idalia’s circulation away from circulation in the lower levels of the atmosphere. Drier air wrapped into the southern and eastern parts of Tropical Storm Idalia. As a result of the strong vertical wind shear and the drier air, the bands revolving around the center of Idalia’s circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation.

Tropical Storm Idalia will move through an environment unfavorable for intensification during the next 36 hours. Idalia will move over water where the Sea Surface Temperatures are near 29°C. However, the upper level trough over the east coast of the U.S. will continue to cause strong vertical wind shear. The strong vertical wind shear and drier air are likely to cause Tropical Storm Idalia to weaken during the next 36 hours. Idalia could exhibit many of the characteristics of an extratropical cyclone.

The upper level trough over the east coast of the U.S. will steer Tropical Storm Idalia toward the east during the next 36 hours. On its anticipated track, Idalia will move quickly away from North Carolina. Tropical Storm Idalia will approach Bermuda during the weekend.

An upper level trough over the eastern U.S. will steer Tropical Storm Idalia toward the northeast during the next 12 hours. The upper level trough will pass north of Idalia on Thursday. The trough will steer Tropical Storm Idalia toward the east-northeast on Thursday. On its anticipated track, the center of Tropical Storm Idalia will move near the coast of South Carolina and North Carolina.

Tropical Storm Idalia will weaken gradually during the next 24 hours. The strongest winds in Idalia will occur over the Atlantic Ocean and along the coast of South Carolina and North Carolina. The winds will be weaker in parts of South Carolina and North Carolina that are farther inland. The southerly winds in the eastern part of Idalia will blow water toward the coast. Those winds will cause a storm surge along the coast of up to 7 feet (2 meters). A Storm Surge Warning was in effect for the portion of the coast from St. Catherine’s Sound, Georgia to South Santee River, South Carolina.

The southerly winds blowing in the eastern side of Tropical Storm Idalia will converge with northerly winds blowing around a high pressure system over the Great Lakes. The low level convergence of air will enhance rising motion and prolonged rainfall could occur over inland parts of South Carolina and North Carolina. Flood Watches are in effect for parts of eastern Georgia, South Carolina and North Carolina.

Elsewhere over the Atlantic Ocean, bands in the eastern side of Hurricane Franklin were producing gusty winds in Bermuda. At 5:00 p.m. EDT on Wednesday the center of Hurricane Franklin was located at latitude 34.2°N and longitude 65.9°W which put it about 145 miles (235 km) north-northwest of Bermuda.

Hurricane Idalia intensified steadily during Tuesday afternoon. A circular eye with a diameter of 30 miles (50 km) was at the center of Idalia’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Idalia’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Idalia grew larger when Idalia intensified. Winds to hurricane force extended out 25 miles (40 km) from the center of Idalia’s circulation. Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Hurricane Ida. Winds to tropical storm force extended out 70 miles in the western side of Ida’s circulation. The Hurricane Intensity Index (HII) for Hurricane Ida was 16.5. The Hurricane Size Index (HSI) was 8.0 and the Hurricane Wind Intensity Size Index (HWISI) was 24.5.

Hurricane Idalia will move through an environment that will be favorable for intensification during the next 12 hours. Idalia will be over water where the Sea Surface Temperatures are near 30°C. It will move into a region between an upper level ridge over the Yucatan Peninsula and an upper level trough over the central U.S. The upper level winds are weaker between the ridge and the trough and there will be little vertical wind shear during the next 12 hours. The upper level winds will be stronger when Idalia moves closer to the upper level trough on Wednesday morning. Hurricane Idalia will intensify during the next 12 hours. Idalia could rapidly intensify at times. Hurricane Idalia is likely to strengthen to a major hurricane.

Hurricane Idalia will move around the western end of high pressure system over the western Atlantic Ocean. The high pressure system and the upper level trough over the central U.S. will steer Idalia toward the north-northeast during the next 12 hours. The upper level trough will turn Idalia toward the northeast on Wednesday. On its anticipated track, Hurricane Idalia will likely to make landfall on the coast of the northeast Gulf of Mexico on Wednesday morning. Idalia is likely to make landfall as a major hurricane.

Hurricane Idalia is forecast to be a major hurricane when it reaches the coast of Florida. Idalia could be similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005. Hurricane Idalia is likely to make landfall in an area where high storm surges can occur. Idalia could cause a storm surge of up to 15 feet (4.5 meters) near where the center makes landfall. A Storm Surge Warning has been issued for the portion of the coast from Englewood to Indian Pass, Florida. The Storm Surge Warning includes Tampa Bay. Hurricane Idalia will bring strong winds and heavy rain to parts of central and northern Florida. Idalia will be capable of causing major damage over parts of northern and northeastern Florida. Widespread outages of electricity are likely. Heavy rain could cause flash floods in some locations. Strong winds and heavy rain will spread over eastern Georgia, South Carolina and North Carolina when Idalia moves toward the northeast.
