Tropical Storm Tammy Moves Away From Bermuda

Tropical Storm Tammy moved away from Bermuda on Saturday. At 11:00 a.m. EDT on Saturday the center of Tropical Storm Tammy was located at latitude 33.3°N and longitude 58.7°W which put it about 360 miles (580 km) east-northeast of Bermuda. Tammy was moving toward the east at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 985 mb.

Tropical Storm Tammy weakened on Saturday as it moved under the southern extent of the upper level westerlies in the middle latitudes. The upper level westerly winds blew toward the top of Tammy’s circulation and they also caused strong vertical wind shear. The wind shear caused the distribution of thunderstorms in Tropical Storm Tammy to become asymmetrical. Thunderstorms were occurring in bands in the eastern side of Tammy’s circulation. Bands in the western half of Tropical Storm Tammy consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tammy’s circulation.

Tropical Storm Tammy will move through an environment that will be unfavorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 25°C. The upper level westerly winds will continue to cause strong vertical wind shear. The combination of marginal Sea Surface Temperatures and strong vertical wind shear will continue to create an environment unfavorable for intensification during the next 24 hours.

Tropical Storm Tammy will move around the northern side of a high pressure system over the eastern Atlantic Ocean. The high pressure system will steer Tammy toward the east during the next 24 hours. On its anticipated track, Tropical Storm Tammy will move farther away from Bermuda.

Tammy Makes a Transition Back to a Tropical Storm

Former Hurricane Tammy made a transition back to a tropical storm east of Bermuda on Friday morning. At 11:00 a.m. EDT on Friday the center of Tropical Storm Tammy was located at latitude 32.2°N and longitude 61.1°W which put it about 215 miles (350 km) east of Bermuda. Tammy was moving toward the northwest at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 65 m.p.h. (95 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 988 mb.

Former Hurricane Tammy made a transition from an extratropical cyclone back to a tropical storm east of Bermuda on Friday morning. The circulation of Tropical Storm Tammy became separated from the occluded front that had formed on Thursday. More thunderstorms formed near the center of Tammy’s circulation. The circulation became more symmetrical and it had the appearance of a tropical storm on visible satellite images. Based on the changes in the circulation’s structure, the U.S. National Hurricane Center designated Tammy as a tropical storm again.

Bands of showers and thunderstorms were revolving around the center of Tropical Storm Tammy. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 205 miles (335 km) in the northern side of Tammy’s circulation. Winds to tropical storm force extended out 90 miles in the southern side of the circulation.

Tropical Storm Tammy will be in an environment somewhat favorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 26°C. It will be in a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Tammy could intensify back to a hurricane during the next 24 hours.

Tropical Storm Tammy will be in an area where the steering level winds are weak during the next 12 hours. Tammy could meander east of Bermuda during the rest of Friday. A high pressure system centered southeast of Bermuda will steer Tropical Storm Tammy toward the east during the weekend. On its anticipated track, Tropical Storm Tammy will move away from Bermuda during the weekend.

Tammy Makes Transition to Strong Extratropical Cyclone

Former Hurricane Tammy made a transition to a strong extratropical cyclone on Wednesday night. At 5:00 a.m. EDT on Thursday the center of former Hurricane Tammy was located at latitude 30.5°N and longitude 58.4°W which put it about 395 miles (640 km) east-southeast of Bermuda. Tammy was moving toward the north at 12 m.p.h. (19 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 973 mb.

Former Hurricane Tammy made a transition to a strong extratropical cyclone over the Atlantic Ocean east-southeast of Bermuda on Wednesday night. The lower part of Tammy’s circulation merged with a frontal system east of Bermuda. Tammy looked like an occluded extratropical cyclone on satellite images. An occluded front wrapped around the northern part of former Hurricane Tammy. A warm front stretched east of the occluded front. A cold front curved south to the Northern Leeward Islands. The upper part of Tammy’s circulation was captured by an upper level trough near Bermuda.

Former Hurricane Tammy was still producing winds to hurricane force. Winds to hurricane force extended out 30 miles (50 km) from the center of Tammy’s circulation. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation.

Former Hurricane Tammy is forecast to meander over the Atlantic Ocean east of Bermuda during the next few days. The upper level trough near Bermuda is between an upper level ridge over the southeastern U.S. and a second upper level ridge over the eastern Atlantic Ocean. The two ridges will keep the upper level trough from moving much. Since the upper level trough captured former Hurricane Tammy, Tammy is not likely to move much either.

There is a possibility that former Hurricane Tammy could make a transition back to a tropical cyclone during the next few days. Tammy will meander over water where the Sea Surface Temperatures are near 26°C. The vertical wind shear will decrease if the upper level trough weakens. If more thunderstorms form near the center of Tammy’s circulation and the fronts dissipate over time, then Tammy could make a transition back to a tropical cyclone.

Former Hurricane Tammy could bring gusty winds to Bermuda during the next few days. The western part of Tammy’s circulation could extend over Bermuda at times as Tammy meanders east of Bermuda.

Hurricane Tammy Spins Southeast of Bermuda

Hurricane Tammy was spinning southeast of Bermuda on Tuesday evening. At 11:00 p.m. EDT on Tuesday the center of Hurricane Tammy was located at latitude 24.9°N and longitude 60.7°W which put it about 570 miles (915 km) southeast of Bermuda. Tammy was moving toward the northeast at 9 m.p.h. (15 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 976 mb.

Hurricane Tammy started to intensify again on Tuesday evening. A small circular eye was at the center of Tammy’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 Hurricane Tammy. Storms near the core generated upper level divergence that pumped mass away to the northeast of the hurricane.

Winds to hurricane force extended out 25 miles (40 km) in the eastern side of Hurricane Tammy. Winds to tropical storm force extended out 170 miles (275 km) in the eastern side of Tammy’s circulation. Winds to tropical storm force extended out 90 miles (145 km) in the western half of Hurricane Tammy.

Hurricane Tammy will move through an environment favorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 27°C. It will move under the eastern side of an upper level trough that is east of the U.S. The upper level trough will produce southwesterly winds that will blow toward the top of Tammy’s circulation. Those winds will cause some vertical wind shear, but the wind shear is not likely to be strong enough to prevent intensification. Hurricane Tammy is likely to intensify on Wednesday.

The upper level trough east of the U.S. will steer Hurricane Tammy toward the northeast during the next 24 hours. On its anticipated track, Hurricane Tammy will remain southeast of Bermuda on Wednesday.

Tropical Depression Forms Near Nicaragua

Tropical Depression Twentyone formed over the southwest Caribbean Sea near Nicaragua on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Depression Twentyone was located at latitude 11.6°N and longitude 83.5°W which put it about 35 miles (55 km) southeast of Bluefields, Nicaragua. The tropical depression was moving toward the west at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1007 mb.

A low pressure system over the southwest Caribbean Sea near Nicaragua strengthened on Monday afternoon and the U.S. National Hurricane Center designated the system as Tropical Depression Twentyone. More thunderstorms formed near the center of the tropical depression on Monday afternoon. Several short bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Twentyone will move around the southern side of a high pressure system over the Gulf of Mexico. The high pressure system will steer the tropical depression toward the west during the next 24 hours. On its anticipated track, Tropical Depression Twentyone will move inland over southeast Nicaragua in a few hours. The tropical depression could drop heavy rain over parts of Nicaragua. Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Tammy moved farther north of the Leeward Islands. At 5:00 p.m. EDT on Monday the center of Hurricane Tammy was located at latitude 22.3°N and longitude 63.8°W which put it about 695 miles (1115 km) south of Bermuda.

Philippe was moving toward the north-northeast 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 1003 mb.

The circulation around Tropical Storm Philippe brought gusty winds to Bermuda on Friday morning. A weather station at L.F. Wade International Airport (TXKF) reported a sustained wind speed of 30 m.p.h. (50 km/h) and a gust of 56 m.p.h. (91 km/h). A weather station at an elevated location near the Bermuda National Museum reported a sustained wind speed of 46 m.p.h. (74 km/h) and a wind gust of 57 m.p.h. (91 km/h). Philippe produce intermittent rain showers in Bermuda, but the heaviest rain passed to the east of Bermuda.

Tropical Storm Philippe made a transition to an extratropical cyclone on Friday morning. The circulation former Tropical Storm Philippe combined with a frontal system near Bermuda. A warm front extended to the east of the center of circulation and a cold front trailed south of the center. Winds to tropical storm force extended out 175 miles (280 km) in the eastern side of former Tropical Storm Philippe. The winds in the western side of the extratropical cyclone were blowing at less than tropical storm force.

Former Tropical Storm Philippe will move between a high pressure system over the Atlantic Ocean and an upper level trough over the Great Lakes. The high pressure system and the upper level trough will steer the extratropical cyclone toward the north during the next 48 hours. On its anticipated track, former Tropical Storm Philippe will affect the Northeast U.S. and the Canadian Maritimes during the weekend. The extratropical cyclone could produce locally heavy rain in some places. Heavy rain could cause flash floods in some locations. Gusty winds could knock down trees and localized outages of electricity are possible.

Philippe Prompts Tropical Storm Warning for Bermuda

The potential effects of Tropical Storm Philippe prompted Bermuda to issue a Tropical Storm Warning. At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Philippe was located at latitude 22.6°N and longitude 65.9°W which put it about 675 miles (1085 km) south of Bermuda. Philippe was moving toward the north at 12 m.p.h. (19 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.

A Tropical Storm Warning was in effect for Bermuda.

Tropical Storm Philippe weakened a little more on Wednesday. An upper level trough east of Florida produced strong southwesterly winds that blew across the top of Philippe’s circulation. Those winds caused strong vertical wind shear. The strong upper level winds also blew the tops off of many of the thunderstorms in Tropical Storm Philippe. A few thunderstorms were able to develop in the southeastern quadrant of Philippe’s circulation. However, most of the bands revolving around the center of Philippe’s circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 200 miles (320 km) in the eastern side of Philippe’s circulation. The winds in the western side of Tropical Storm Philippe were blowing at less than tropical storm force.

Tropical Storm Philippe will move through a region that will be unfavorable for intensification during the next 24 hours. Philippe will move over water where the Sea Surface Temperatures are near 29°C. However, the upper level trough east of Florida will continue to cause strong vertical wind shear. The strong wind shear will prevent Tropical Storm Philippe from intensifying during the next 24 hours.

Tropical Storm Philippe will move around the western part of a high pressure system over the Atlantic Ocean. The high pressure system will steer Philippe toward the north during the next 24 hours. On its anticipated track, Tropical Storm Philippe will move closer to Bermuda. Philippe could reach Bermuda on Friday.

Hurricane Nigel Moves North

Hurricane Nigel moved toward the north of the central Atlantic Ocean on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Hurricane Nigel was located at latitude 37.4°N and longitude 53.0°W which put it about 755 miles (1215 km) east-northeast of Bermuda. Nigel was moving toward the north-northeast at 18 m.p.h. (30 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 973 mb.

A large, circular eye with a diameter of 70 miles (110 km) was at the center of Hurricane Nigel on Wednesday afternoon. 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 large core of Nigel’s circulation. Storms near the core generated upper level divergence that pumped mass away to the north of the hurricane. Winds to hurricane force extended out 60 miles (95 km) from the center of Nigel’s circulation. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Hurricane Nigel will move through an environment that will be unfavorable for intensification during the next 24 hours. Nigel will move over water where the Sea Surface Temperatures are cooler than 26°C. An upper level trough over the East Coast of the U.S. will produce southwesterly winds that will blow toward the top of Nigel’s circulation. Those winds will cause the vertical wind shear to increase. More wind shear and cooler water will cause Hurricane Nigel to weaken on Thursday. The vertical wind shear and cooler water will also cause Hurricane Nigel to start a transition to a strong extratropical cyclone.

The upper level trough over the East Coast of the U.S. will steer Hurricane Nigel toward the northeast during the next 24 hours. On its anticipated track, NIgel will pass far to the southeast of Newfoundland.

Hurricane Nigel Strengthens East of Bermuda

The minimum surface pressure was 974 mb.

A large, circular eye with a diameter of 60 miles (95 km) was at the center of Hurricane Nigel on Tuesday afternoon. 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 Nigel’s circulation. Storms near the core generated upper level divergence that pumped mass away to the north of the hurricane. Winds to hurricane force extended out 60 miles (95 km) from the center of Nigel’s circulation. Winds to tropical storm force extended out 175 miles (280 km) from the center of circulation.

Hurricane Nigel will move through an environment somewhat favorable for intensification during the next 24 hours. Nigel will move over water where the Sea Surface Temperatures are near 27°C. It will move under the western part of an upper level ridge over the central Atlantic Ocean. The upper level ridge will produce southerly winds that will blow toward the top of Nigel’s circulation. Those winds will cause some vertical wind shear and the shear will inhibit intensification. Tropical Storm Nigel could strengthen on Wednesday. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Nigel’s circulation later this week. Those winds will cause the vertical wind shear to increase. More wind shear will cause Hurricane Nigel to weaken later this week.

Hurricane Nigel will move around the western part of a high pressure system over the eastern Atlantic Ocean. The high pressure system will steer Nigel toward the north during the next 24 hours. On its anticipated track, Hurricane Nigel will stay far east of Bermuda. The upper level trough over the eastern U.S. will steer Nigel toward the northeast later this week.
