Tropical Storm Ernesto Brings Wind and Rain to the Leeward Islands

Tropical Storm Ernesto brought wind and rain to the Leeward Islands on Tuesday morning. At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Ernesto was located at latitude 16.6°N and longitude 61.9°W which put the center about 35 miles (55 km) northwest of Guadeloupe. Ernesto was moving toward the west at 18 m.p.h. (30 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 1005 mb.

Tropical Storm Warnings were in effect for Guadeloupe, St. Martin, St. Barthelemy, St, Kitts, Nevis, Montserrat, Antigua, Barbuda, Anguilla, Saba, St. Eustatius, Sint Maarten, the British Virgin Islands, the U.S. Virgin Islands, Puerto Rico, Culebra, Vieques.

More thunderstorms formed near the center of Tropical Storm Ernesto on Tuesday morning. Those thunderstorms generated more upper level divergence that removed mass from the tropical storm. The removal of more mass cause the surface pressure to decrease. More thunderstorms also developed in bands revolving around the center of Ernesto’s circulation

The strongest winds were occurring in the northern side of Tropical Storm Ernesto. Winds to tropical storm force extended out 70 miles (110 km) in the northern side of Ernesto’s circulation. The winds in the southern part of Ernesto were blowing at less than tropical storm force.

Tropical Storm Ernesto will move through an environment favorable for intensification during the next 24 hours. Ernesto will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the subtropical Atlantic Ocean. The ridge will produce easterly winds that will blow toward the top of Ernesto’s circulation. Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification. Tropical Storm Ernesto will intensify during the next 24 hours.

Tropical Storm Ernesto will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer the tropical wave quickly toward the west-northwest during the next 24 hours. On its anticipated track, Tropical Storm Ernesto will reach Puerto Rico on Tuesday night.

Tropical Storm Ernesto will bring gusty winds and locally heavy rain to the Leeward Islands, the British Virgin Islands, the U.S. Virgin Islands and Puerto Rico. Heavy rain is likely to cause flash floods in some locations. The winds could be strong enough to cause localized outages of electricity. Ernesto could also cause a storm surge of up to 4 feet (1 meter).

Tropical Storm Ernesto Forms East of the Leeward Islands

Tropical Storm Ernesto formed east of the Leeward Islands on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Storm Ernesto was located at latitude 16.0°N and longitude 57.5°W which put the center about 295 miles (475 km) east-southeast of Antigua. Ernesto was moving toward the west-northwest at 28 m.p.h. (44 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 1009 mb.

A U.S. Air Force Reserve Hurricane Hunter aircraft found a distinct low level center of circulation in a tropical wave previously designated as Potential Tropical Cyclone Five, and the U.S. National Hurricane Center designated the system as Tropical Storm Ernesto.

More thunderstorms formed near the center of Tropical Storm Ernesto. Bands of showers and thunderstorms began to revolve around the center of Ernesto’s circulation. Storms near the center of Ernesto started to generate upper level divergence that pumped mass away from the tropical storm.

The reconnaissance plane also found that tropical storm force winds extended out 60 miles (95 km) in the northeastern quadrant of Tropical Storm Ernesto. The winds in the other parts of Ernesto’s circulation were blowing at less than tropical storm force.

Tropical Storm Ernesto will move through an environment somewhat favorable for intensification during the next 24 hours. Ernesto will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the subtropical Atlantic Ocean. The ridge will produce strong easterly winds that will blow toward the top of the tropical wave. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear is not enough to stop intensification. Tropical Storm Ernesto is likely to intensify gradually during the next 24 hours.

Tropical Storm Ernesto will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer the tropical wave quickly toward the west-northwest during the next 24 hours. On its anticipated track, ‘Tropical Storm Ernesto could reach the Leeward Islands early on Tuesday. Ernesto could be near Puerto Rico on Tuesday night.

Tropical Storm Warnings Issued for Leeward Islands, Virgin Islands and Puerto Rico

The potential risk posed by a tropical wave currently designated as Potential Tropical Cyclone Five prompted the issuance of Tropical Storm Warnings for the Leeward Islands, the Virgin Islands, and Puerto Rico on Monday morning. At 11:00 a.m. EDT on Monday the center of Potential Tropical Cyclone Five was located at latitude 15.1°N and longitude 55.6°W which put the center about 435 miles (700 km) east-southeast of Antigua. The tropical wave was moving toward the west at 26 m.p.h. (43 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 1010 mb.

A tropical wave east of the Lesser Antilles that is currently designated as Potential Tropical Cyclone Five exhibited more organization on Monday morning. However, a NOAA aircraft investigating the tropical wave did not find a well defined low level center of circulation. More thunderstorms formed near the axis of the tropical wave. A large counterclockwise rotation associated with the tropical wave strengthened a little on Monday morning. Bands of showers and thunderstorms appeared to be forming in parts of the tropical wave.

Potential Tropical Cyclone Five will move through an environment somewhat favorable for the formation of a tropical cyclone during the next 24 hours. The tropical wave will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the subtropical Atlantic Ocean. The ridge will produce strong easterly winds that will blow toward the top of the tropical wave. Those winds will cause moderate vertical wind shear. The wind shear will slow the organization of the tropical wave into a tropical cyclone. Potential Tropical Cyclone Five is likely to organize gradually into a tropical depression or a tropical storm during the next 24 hours.

Potential Tropical Cyclone Five will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer the tropical wave quickly toward the west-northwest during the next 24 hours. On its anticipated track, Potential Tropical Cyclone Five could approach the Leeward Islands on Monday night. It could be near Puerto Rico on Tuesday night.

Potential Tropical Cyclone Five could be a tropical storm when it reaches the Leeward Islands. It will bring gusty winds and locally heavy rain to the Leeward Islands, the British Virgin Islands, the U.S. Virgin Islands and Puerto Rico. Heavy rain is likely to cause flash floods in some locations. The winds could be strong enough to cause localized outages of electricity.

Tropical Storm Watches Issued for Leeward Islands

The potential threat posed by a tropical wave east of the Lesser Antilles prompted the issuance of Tropical Storm Watches for the Leeward Islands on Sunday afternoon. The U.S. National Hurricane Center designated the tropical wave as Potential Tropical Cyclone Five for the purpose of issuing the Tropical Storm Watches. At 5:00 p.m. EDT on Sunday the center of Potential Tropical Cyclone Five was located at latitude 13.6°N and longitude 48.0°W which put the center about 950 miles (1530 km) east-southeast of Antigua.

Tammy Strengthens to a Hurricane East of the Lesser Antilles

Former Tropical Storm Tammy strengthened to a hurricane east of the Lesser Antilles on Friday morning. At 11:00 a.m. EDT on Friday the center of Hurricane Tammy was located at latitude 14.1°N and longitude 58.6°W which put it about 165 miles (265 km) east-southeast of Martinique. Tammy was moving toward the west-northwest at 7 m.p.h. (11 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 992 mb.

Hurricane Warnings were in effect for Guadeloupe, Antigua, Barbuda, Montserrat, St. Kitts, and Nevis. Hurricane Watches were in effect for Anguilla, St. Maarten, St. Martin, and St. Baarthelemy. Tropical Storm Warnings were in effect for Dominica, Anguilla, St. Maarten, St. Martin, St. Barthelemy, Saba and St. Eustatius. Tropical Storm Watches were in effect for Martinique and Barbados.

U.S. Air Force Reserve and NOAA planes flying in former Tropical Storm Tammy found that Tammy had intensified to a hurricane on Friday morning. A circular eye with a diameter of 14 miles (22 km) formed at the center of Hurricane Tammy. 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 from the hurricane. The removal of mass caused the surface pressure to decrease on Friday morning.

Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Hurricane Tammy. Winds to tropical storm force extended out 140 miles (220 km) in the eastern side of Tammy’s circulation. Winds to tropical storm force extended out 90 miles (145 km) in the western side of the circulation.

Hurricane Tammy will move through an environment somewhat favorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 30°C. It will move under the far eastern part of an upper level low over the Eastern Caribbean Sea. The upper level low will produce southwesterly winds that will blow toward the top of Tammy’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Hurricane Tammy is likely to intensify during the next 24 hours.

Hurricane Tammy will move south of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Tammy toward the northwest during the next 24 hours. On its anticipated track, the center of Hurricane Tammy could be near Guadeloupe on Saturday morning.

Hurricane Tammy is likely to bring strong winds and locally heavy rain to the central and northern Leeward Islands. Heavy rain is likely to cause flash in some locations. Hurricane Tammy could cause a storm surge of up to seven feet (two meters) along the coasts of some of the islands.

Tropical Storm Tammy Strengthens East of the Lesser Antilles

Tropical Storm Tammy strengthened east of the Lesser Antilles on Thursday morning. At 8:00 a.m. EDT on Thursday the center of Tropical Storm Tammy was located at latitude 13.5°N and longitude 55.1°W which put it about 465 miles (745 km) east of Guadeloupe.

A NOAA research plane found that Tropical Storm Tammy had strengthened during Wednesday night. More thunderstorms developed near the center of Tammy’s circulation. However, the distribution of thunderstorms was still asymmetrical. Many of the thunderstorms were occurring in bands in the eastern side of Tropical Storm Tammy. Bands in the western side of Tammy’s circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away to the north and east of the tropical storm. Winds to tropical storm force extended out 140 miles (220 km) in the eastern side of Tropical Storm Tammy. Winds to tropical storm force extended out 70 miles (110 km) in the western side of Tammy.

Tropical Storm Tammy will move through an environment somewhat favorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 30°C. It will move under the far eastern part of an upper level low over the Eastern Caribbean Sea. The upper level low will produce southwesterly winds that will blow toward the top of Tammy’s circulation. The winds in the lower levels of the atmosphere are blowing from the east. The difference in wind direction between the upper and lower levels of the atmosphere will cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Tammy could intensify gradually during the next 24 hours.

Tropical Storm Tammy will move south of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Tammy toward the west-northwest during the next 24 hours. On its anticipated track, Tropical Storm Tammy could approach the central and northern Leeward Islands on Friday.

Tropical Storm Tammy is likely to bring gusty winds and locally heavy rain to the central and northern Leeward Islands. Heavy rain is likely to cause flash in some locations. Tropical Storm Tammy could cause a storm surge of up to seven feet (two meters) along the coasts of some of the islands.

A low pressure system over the Atlantic Ocean east of the Lesser Antilles strengthened on Wednesday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Tammy. The circulation around Tropical Storm Tammy was not well organized. Many of the thunderstorms were occurring in bands in the eastern part of Tammy’s circulation. Bands in the western part of Tropical Storm Tammy consisted primarily of showers and lower clouds. Storms near the center of Tammy’s circulation were beginning to generate upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 140 miles (220 km) in the northeastern quadrant of Tropical Storm Tammy. The winds in the other parts of Tammy were blowing at less than tropical storm force.

Tropical Storm Tammy is likely to bring gusty winds and locally heavy rain to Barbados, Dominica, Martinique and Guadeloupe. Heavy rain is likely to cause flash in some locations.

Philippe Weakens North of the Virgin Islands

Tropical Storm Philippe weakened north of the Virgin Islands on Tuesday. At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Philippe was located at latitude 19.0°N and longitude 64.4°W which put it about 55 miles (90 km) northeast of St. Thomas. Philippe was moving toward the northwest at 10 m.p.h. (16 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 1004 mb.

A Tropical Storm Watch was in effect for the British Virgin Islands.

Tropical Storm Philippe weakened north of the Virgin Islands on Tuesday. An upper level ridge over the eastern Caribbean Sea produced strong westerly winds that blew across the top of Philippe’s circulation. Those winds caused strong vertical wind shear. The strong upper level winds blew the tops off of most of the thunderstorms in the southeastern part of Tropical Storm Philippe. 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 170 miles (275 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 ridge over the eastern Caribbean Sea will continue to cause strong vertical wind shear. The wind shear will likely cause Tropical Storm Philippe to weaken more during the next 24 hours.

Tropical Storm Philippe will move around the southwestern part of a high pressure system over the Atlantic Ocean. The high pressure system will steer Philippe toward the north-northwest during the next 24 hours. On its anticipated track, Tropical Storm Philippe will move away from Puerto Rico and the Virgin Islands.

Bands in the southeastern part of Tropical Storm Philippe did drop heavy rain over the Northern Leeward Islands during Monday night and Tuesday morning. Heavy rain fell on parts of Guadeloupe, Antigua, Barbuda, and Anguilla. There were reports of flash floods in some locations.

Tropical Storm Philippe Prompts Watches for Antigua and Barbuda

A potential risk caused by Tropical Storm Philippe prompted the issuance of Tropical Storm Watches for Antigua and Barbuda on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Philippe was located at latitude 16.6°N and longitude 59.1°W which put it about 155 miles (245 km) east of Guadeloupe. Philippe was moving toward the west-northwest at 5 m.p.h. (8 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 998 mb.

Tropical Storm Watches were in effect for Antigua and Barbuda.

Tropical Storm Philippe did not move much on Sunday. The circulation around Philippe also did not change much on Sunday. An upper level ridge over the eastern Caribbean Sea continued to produce northwesterly winds that blew toward the top of Philippe’s circulation. Those winds caused strong vertical wind shear. The vertical wind shear caused the distribution of thunderstorms in Tropical Storm Philippe to be asymmetrical. Most of the thunderstorms were occurring in bands in the southeastern part of Philippe’s circulation. Bands near the center of Tropical Storm Philippe and in the other parts of the circulation consisted primarily of showers and lower clouds. The distribution of wind speeds was also asymmetrical. Winds to tropical storm force extended out 170 miles (275 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 ridge over the eastern Caribbean Sea will continue to cause strong vertical wind shear. The wind shear is likely to prevent intensification of Tropical Storm Philippe on Monday.

Tropical Storm Philippe will move around the southwestern part of a high pressure system over the Atlantic Ocean. The high pressure system will steer Philippe toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Philippe could move a little closer to Antigua and Barbuda on Monday.

Elsewhere over the Atlantic Ocean, former Tropical Storm Rina weakened to a tropical depression northeast of the Leeward Islands. At 11:00 p.m. EDT on Sunday the center of Tropical Depression Rina was located at latitude 27.1°N and longitude 55.4°W which put it about 785 miles (1265 km) northeast of the Northern Leeward Islands. Rina was moving toward the north at 13 m.p.h. (21 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 1010 mb.

Tropical Storm Fiona Brings Wind and Rain to the Leeward Islands

Tropical Storm Fiona brought wind and rain to the Leeward Islands on Friday night. At 11:00 p.m. EDT on Friday the center of Tropical Storm Fiona was located at latitude 16.6°N and longitude 62.2°W which put it about 55 miles (90 km) west-northwest of Guadeloupe. Fiona was moving toward the west at 14 m.p.h. (22 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). The minimum surface pressure was 1002 mb.

Tropical Storm Warnings were in effect for Saba, St. Eustatius, St. Maarten, Antigua, Barbuda, St. Kitts, Nevis, Montserrat, Anguilla, Guadeloupe, St. Martin and St. Barthelemy, Puerto Rico, Culebra, Vieques, the U.S. Virgin Islands, the British Virgin Islands and the portion of the coast from Cabo Caucedo to Puerto Plata, Dominican Republic. Tropical Storm Watches were in effect for Dominica and for the portion of the coast from Cabo Caucedo to Barahona, Dominican Republic.

More thunderstorms developed near the center of Tropical Storm Fiona on Friday night which caused Fiona to strengthen. Although there were more thunderstorms near the center of circulation, most of the thunderstorms were still occurring in bands on the eastern side of Tropical Storm Fiona. Bands in the western half of the circulation consisted primarily of showers and lower clouds. The new thunderstorms near the center of Fiona generated upper level divergence that pumped mass away to the north and east of the tropical storm. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tropical Storm Fiona.

Tropical Storm Fiona will move through an environment somewhat favorable for intensification during the next 24 hours. Fiona will move over water where the Sea Surface Temperatures are near 29˚C. An upper level ridge over the tropical Atlantic Ocean will produce southwesterly winds that will blow toward the top of Tropical Storm Fiona. Those winds will cause vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Fiona could continue to strengthen gradually, but the wind shear will limit intensification during the next 24 hours.

Tropical Storm Fiona will move around the southern side of the subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Fiona toward the west-northwest during the next 36 hours. Tropical Storm Fiona will continue to cause gusty winds and locally heavy rain to the northern Leeward Islands during the next 12 hours. Heavy rain could cause flash floods in some locations. On its anticipated track Tropical Storm Fiona could be southeast of Puerto Rico by Saturday evening. Fiona could be near the eastern end of the Dominican Republic by Sunday evening. There is a chance that Fiona could be a hurricane by that time.
