Hurricane Lee was in the middle of a transition to an extratropical cyclone on Friday afternoon. 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 southerly 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 half of Lee’s circulation, Bands in the southern half of Hurricane Lee 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 115 miles (185 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 11.5. The Hurricane Size Index (HSI) was 39.8 and the Hurricane Wind Intensity Size Index (HWISI) was 51.3. 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 colder than 26°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 colder water, moderate vertical wind shear and the drier air will cause Hurricane Lee to weaken gradually during the next 24 hours. That same combination of environmental factors will also cause Hurricane Lee to complete a transition to an extratropical cyclone on Saturday.

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, Hurricane Lee reach Nova Scotia on Saturday. Even though Hurricane Lee will be making 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 to Nova Scotia, New Brunswick, and Prince Edward Island. Widespread outages of electricity are possible. 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, former Hurricane Margot weakened to a tropical storm west of the Azores and Tropical Depression Fifteen formed east of the Lesser Antilles. At 5:00 p.m. EDT on Friday the center of Tropical Storm Margot was located at latitude 36.0°N and longitude 37.9°W which put it about 615 miles (990 km) west of the Azores. Margot was moving toward the southeast at 3 m.p.h. (5 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 990 mb.

At 5:00 p.m. EDT on Friday the center of Tropical Depression Fifteen was located at latitude 15.4°N and longitude 44.0°W which put it about 1150 miles (1885 km) west of the Azores. The tropical depression was moving toward the northwest at 13 m.p.h. (21 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 1007 mb.

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 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.

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.

The center of Hurricane Fiona passed west of Bermuda on Thursday night. The L. F. Wade International Airport in Bermuda reported a sustained wind speed of 64 m.p.h. (103 km/h) and a wind gust of 83 m.p.h. (134 km/h). There were reports of stronger wind speeds measured by automated stations in higher locations in Bermuda.

Hurricane Fiona continued to be a large, well organized hurricane. A circular eye with a diameter of 35 miles (55 km) was at the center of Fiona’s circulation. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms revolved around the core of Hurricane Fiona. Storms near the core generated strong upper level divergence that pumped mass away from the hurricane.

Hurricane Fiona grew into a large hurricane as it moved farther north on Thursday night. Winds to hurricane force extended out 90 miles (145 km) from the center of Fiona. Winds to tropical storm force extended out 345 miles (555 km) from the center of circulation. The Hurricane Intensity Index (HII) was 23.6. The Hurricane Size Index (HSI) was 32.70 and the Hurricane Wind Intensity Size Index (HWISI) was 56.3. Hurricane Fiona was larger than Hurricane Jeanne was in 2004.

Hurricane Fiona will move through an environment that will become less favorable for a major hurricane during the next 24 hours. Fiona will move over water where the Sea Surface Temperatures colder than 26˚C. An upper level trough near the East Coast of the U.S. will produce southwesterly winds that will blow toward the top of Fiona’s circulation. Those winds will cause the vertical wind shear to increase. Hurricane Fiona will start to weaken gradually when the wind shear increase. A combination of colder Sea Surface Temperatures and moderate vertical wind shear will cause Hurricane Fiona to make a transition to a very strong extratropical cyclone.

The upper level trough near the East Coast of the U.S. will steer Fiona toward the north-northeast during the next 24 hours. On its anticipated track, Hurricane Fiona will move away from Bermuda on Friday. Hurricane Fiona will approach the Canadian Maritimes on Friday night. Fiona will bring strong, destructive winds to the Canadian Maritimes. Heavy rain could cause floods in some locations.

Elsewhere over the Atlantic Ocean, Tropical Storm Gaston was bringing wind and rain to the Azores and Tropical Depression Nine formed over the southeastern Caribbean Sea. Tropical Storm Warnings were in effect for Corvo, Flores, Faial, Pico, Sao Jorge, Graciosa, and Terceira. At 8:00 a.m. EDT on Friday the center of Tropical Storm Gaston was located at latitude 40.5°N and longitude 29.2°W which put it about 135 miles (215 km) north-northwest of the Faial. Gaston was moving toward the east-southeast at 7 m.p.h. (11 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).

It could move over the southeastern Gulf of Mexico early next week.

Hurricane Dorian Brings Powerful Winds to Nova Scotia

Hurricane Dorian brought powerful winds to Nova Scotia on Saturday.  At 8:00 p.m. EDT on Saturday the center of Hurricane Dorian was located at latitude 45.0°N and longitude 67.9°W which put it about 45 miles (75 km) northeast of Halifax, Nova Scotia.  Dorian was moving toward the northeast at 30 m.p.h. (48 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 960 mb.

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

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

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

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

Hurricane Dorian Makes Landfall at Cape Hatteras, Threatens Canadian Maritimes

Hurricane Dorian made an official landfall at Cape Hatteras, North Carolina on Friday morning and posed a serious threat to the Canadian Maritime provinces.  At 5:00 p.m. EDT on Friday the center of Hurricane Dorian was located at latitude 36.9°N and longitude 72.7°W which put it about 330 miles (530 km) south-southwest of Nantucket, Massachusetts.  Dorian was moving toward the northeast at 24 m.p.h. (39 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surace pressure was 958 mb.

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

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

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

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