Tropical Storm Oscar Meanders Over Eastern Cuba

Tropical Storm Oscar meandered over eastern Cuba on Monday.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Oscar was located at latitude 21.0°N and longitude 76.1°W which put the center about 80 miles (130 km) northwest of Guantanamo, Cuba.  Oscar was moving toward the north-northwest at 7 m.p.h. (11 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 Warnings are in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.  Tropical Storm Warnings are in effect for the Southeastern Bahamas.  Tropical Storm Warnings are in effect for the South Coast of Cuban province of Guantanamo and the North Coast of Cuban province of Las Tunas.  Tropical Storm Warnings are in effect for the Central Bahamas.

Former Hurricane Oscar weakened steadily as it meandered over eastern Cuba on Monday.  Many of the thunderstorms in Oscar’s circulation dissipated.  Bands of showers and low clouds were revolving around the center of Tropical Storm Oscar.  The strongest winds were occurring in bands over water north of Cuba.  The winds on land were blowing at less than tropical storm force.

The distribution of winds speeds in Tropical Storm Oscar was asymmetrical.  Winds to tropical storm force extended out 90 miles (145 km) in the eastern side of Oscar’s circulation.  Those winds were occurring in the part of the circulation that was over water.  The winds in the western side of Tropical Storm Oscar were blowing at less than tropical storm force.  Much of the western part of Oscar’s circulation was over eastern Cuba.

Tropical Storm Oscar will move through an environment only marginally favorable for intensification during the next 24 hours.  Oscar will move over water where the Sea Surface Temperatures are near 29°C.  However, it will move under the eastern side of an upper level trough over Florida.  The upper level trough will produce southwesterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause strong vertical wind shear.  The wind shear will inhibit intensification, but Tropical Storm Oscar could get a little stronger on Tuesday.

The upper level trough over Florida will steer Tropical Storm Oscar toward the northeast during the next 24 hours.  On its anticipated track Oscar will move over the Central Bahamas on Tuesday.  Tropical Storm Oscar will bring gusty winds and locally heavy rain to the Central Bahamas.

Hurricane Oscar Brings Wind and Rain to Southeastern Bahamas

Hurricane Oscar brought wind and rain to the Southeastern Bahamas early on Sunday.  At 8:00 a.m. EDT on Sunday the center of Hurricane Oscar was located at latitude 20.8°N and longitude 73.6°W which put the center about 20 miles (30 km) southwest of  Great Inagua.  Oscar was moving toward the west-southwest at 12 m.p.h. (19 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 986 mb.

Hurricane Warnings are in effect for the Southeastern Bahamas.  Hurricane Warnings are also in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.

A Hurricane Watch is in effect for the North Coast of Cuban province of  Las Tunas.

Tropical Storm Warnings are in effect for the South Coast of Cuban province of Guantanamo and the North Coast of Cuban province of Las Tunas.

A Tropical Storm Watch is in effect for the North Coast of Cuban province of Camaguey.

The center of Hurricane Oscar passed over Great Inagua early on Sunday.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.  Storms near the center of Oscar generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 5 miles (8 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move through an environment somewhat favorable for intensification during the next few hours.  Oscar will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern end of an upper level ridge over Cuba.  The upper level ridge will produce northeasterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause some vertical wind shear.  The wind shear may be strong enough to prevent intensification.  Hurricane Oscar is likely to maintain its intensity during the next few hours.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west-southwest during the next 24 hours.  On its anticipated track, Hurricane Oscar will reach eastern Cuba on Sunday afternoon.

Hurricane Oscar will continue to strong winds and locally heavy rain to the Southeastern Bahamas during the next  few hours. Oscar will also bring strong winds and heavy rain to eastern Cuba on Sunday night.  Heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Depression Nadine was moving across southern Mexico. At 5:00 a.m. EDT on Sunday the center of Tropical Depression Nadine was located at latitude 16.8°N and longitude 91.8°W which put the center about 85 miles (135 km) east of Tuxtla Gutierrez, Mexico. Nadine was moving toward the west-southwest at 8 m.p.h. (14 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 1006 mb.

Hurricane Oscar Develops Rapidly Southeast of the Bahamas

Hurricane Oscar developed rapidly over the Atlantic Ocean southeast of the Bahamas on Saturday afternoon.  At 2:00 p.m. EDT on Saturday the center of Hurricane Oscar was located at latitude 21.4°N and longitude 70.6°W which put the center about 165 miles (265 km) east-southeast of the Southeastern Bahamas.  Oscar was moving toward the west at 12 m.p.h. (19 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 989 mb.

A Hurricane Warning is in effect for the Turks and Caicos, and the Southeastern Bahamas.

A Hurricane Watch is in effect for the Cuban provinces of Guantanamo, Holguin, and Las Tunas.

A Tropical Storm Warning is in effect for the Cuban provinces of Guantanamo, Holguin and Las Tunas.

A Hurricane Watch is in effect for the Cuban province of Camaguey.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance plane found that a low pressure system over the Atlantic Ocean southeast of the Bahamas had rapidly developed into a hurricane on Saturday afternoon.  Based on data gather by the reconnaissance flight, the U.S. National Hurricane Center designated the system as Hurricane Oscar.

The circulation around Hurricane Oscar was very small.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.  Storms near the center of Oscar generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 5 miles (8 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move through an environment mostly favorable for intensification during the next 24 hours.  Oscar will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the eastern end of an upper level ridge over the Bahamas.  The upper level ridge will produce northeasterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Hurricane Oscar is likely to intensify during the next 24 hours.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west during the next 24 hours.  On its anticipated track, Hurricane Oscar will move over the Turks and Caicos and the Southeastern Bahamas.  Oscar could approach eastern Cuba on Sunday night.

Hurricane Oscar will bring strong winds and locally heavy rain to the Turks and Caicos and the Southeastern Bahamas.  Heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Storm Nadine brought strong winds and heavy rain to parts of Belize and the Yucatan Peninsula.  At 2:00 p.m. EDT on Saturday the center of Tropical Storm Nadine was located at latitude 17.6°N and longitude 88.5°W which put the center about 20 miles (30 km) west-northwest of Belize City, Belize.  Nadine was moving toward the west at 8 m.p.h. (13 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 1003 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Belize City,, Belize to Cancun, Mexico.  The Tropical Storm Warning includes Cozumel.

Tropical Storm Ophelia Brings Wind and Rain to Eastern North Carolina, Virginia

Tropical Storm Ophelia brought wind and rain to eastern North Carolina and Virginia on Saturday morning. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Ophelia was located at latitude 35.1°N and longitude 77.0°W which put it about 40 miles (65 km) northwest of Cape Lookout, North Carolina. Ophelia was moving toward the north at 13 m.p.h. (21 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 983 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Cape Fear, North Carolina to Fenwick Island, Delaware. The Tropical Storm Warning included Albemarle Sound and Pamlico Sound. A Tropical Storm Warning was also in effect for Chesapeake Bay south of North Beach. A Tropical Storm Warning was in effect for the Tidal Potomac south of Cobb Island.

Tropical Storm Ophelia brought wind and rain as it moved inland over eastern North Carolina on Saturday morning. The circulation around Ophelia was large. Tropical Storm Opehila was interacting with a high pressure system over eastern Canada to produce strong winds northeast of the center of circulation. Winds to tropical storm force extended out 310 miles (500 km) in the northeastern quadrant of Ophelia’s circulation. Winds to tropical storm force extended out 140 miles (225 km) in the other parts of Tropical Storm Ophelia.

A weather station in Cape Lookout, North Carolina reported a sustained wind speed of 47 m.p.h. (75 km/h) and a wind gust of 71 m.p.h. (115 km/h). A weather station in Morehead City, North Carolina reported a sustained wind speed of 43 m.p.h. (68 km/h) and a wind gust of 53 m.p.h. (85 km/h). NOAA buoy 41037 near Wrightsville Beach reported a sustained wind speed of 54 m.p.h. (87 km/h) and a wind gust of 83 m.p.h. (134 km/h).

Tropical Storm Ophelia will move around the western side of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Ophelia toward the north during the next 24 hours. On its anticipated track, Tropical Storm Ophelia will move inland over eastern North Carolina and Virginia. Ophelia will bring strong, gusty winds and locally heavy rain to eastern North Carolina, eastern Virginia, southeastern Maryland and southern Delaware.

The heaviest rain was falling in bands in the northern and western parts of Tropical Storm Ophelia. Bands in the eastern and southern parts of Ophelia’s circulation consisted primarily of showers and lower clouds. Locally heavy rain could cause flash floods in some locations. Flood Watches were in effect for eastern North Carolina, eastern Virginia, Maryland and Delaware.

Easterly winds in the northern side of Tropical Storm Ophelia will blow water toward the coast. A storm surge of up to 6 feet (1.8 meters) could occur in some locations. A Storm Surge Warning was in effect for the portion of the coast from Bogue Inlet, North Carolina to Chincoteague, Virginia. The Storm Surge Warning included Albemarle Sound, Pamlico Sound, the Pamlico River and the Neuse River. A Storm Surge Warning was in effect for Chesapeake Bay south of Colonial Beach, Virginia. Large waves will also cause significant beach erosion.

Tropical Storm Ophelia Develops South of Cape Hatteras

Tropical Storm Ophelia developed south of Cape Hatteras on Friday afternoon. At 2:00 p.m. EDT on Friday the center of Tropical Storm Ophelia was located at latitude 32.7°N and longitude 76.0°W which put it about 185 miles (295 km) south of Cape Hatteras, North Carolina. Ophelia was moving toward the north-northwest at 12 m.p.h. (19 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 992 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Cape Fear, North Carolina to Fenwick Island, Delaware. The Tropical Storm Warning included Albemarle Sound and Pamlico Sound. A Tropical Storm Warning was also in effect for Chesapeake Bay south of North Beach. A Tropical Storm Warning was in effect for the Tidal Potomac south of Cobb Island.

The U.S. National Hurricane Center designated a low pressure system south of Cape Hatteras as Tropical Storm Ophelia on Friday afternoon. Drier air was wrapping around the southern and eastern sides of Ophelia’s circulation. The drier air was making the distribution of thunderstorms asymmetrical. Thunderstorms were occurring in bands in the northern and western parts of Tropical Storm Ophelia. Bands in the southern and eastern parts of Ophelia consisted primarily of showers and lower clouds. Storms north and west of the center of Ophelia’s circulation generated upper level divergence that pumped mass away from the tropical storm. The circulation around Tropical Storm Ophelia was large, Winds to tropical storm force extended out 275 miles (445 km) from the center of circulation.

Tropical Storm Ophelia will move through an environment somewhat favorable for intensification during the next 12 hours. Ophelia will move over the Gulf Stream where the Sea Surface Temperatures are near 30°C. It will move under the eastern side of an upper level trough over the eastern U.S. The upper level trough will produce southwesterly winds that will blow toward the top of Ophelia’s circulation. Those winds will cause moderate vertical wind shear. However, the flow of air in the upper levels will also provide divergence aloft that will pump mass away from the tropical storm. The removal of mass will cause the surface pressure to decrease. The drier air in the southern and eastern parts of Tropical Storm Ophelia will inhibit the formation of thunderstorms in those regions. Tropical Storm Ophelia could intensify during the next 12 hours, while it is over the Gulf Stream.

Tropical Storm Ophelia will move around the western side of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Ophelia toward the north-northwest during the next 24 hours. On its anticipated track, Tropical Storm Ophelia will approach the coast of North Carolina on Friday night. Ophelia will bring strong, gusty winds and locally heavy rain to eastern North Carolina, eastern Virginia, southeastern Maryland and southern Delaware. NOAA buoy 41025 at Diamond Shoals, North Carolina reported a sustained wind speed of 47 m.p.h. (76 km/h) and a wind gust of 60 m.p.h. (97 km/h). A NOAA C-MAN station at Cape Lookout, North Carolina reported a sustained wind speed of 45 m.p.h. (72 km/h) and a wind gust of 53 m.p.h. (83 km/h)

Locally heavy rain could cause flash floods in some locations. Flood Watches were in effect for eastern North Carolina, eastern Virginia, Maryland and Delaware.

Easterly winds in the northern side of Tropical Storm Ophelia will blow water toward the coast. A storm surge of up to 6 feet (1.8 meters) could occur in some locations. A Storm Surge Warning was in effect for the portion of the coast from Beaufort Inlet, North Carolina to Chincoteague, Virginia. The Storm Surge Warning included Albemarle Sound, Pamlico Sound, the Pamlico River and the Neuse River. A Storm Surge Warning was in effect for Chesapeake Bay south of Colonial Beach, Virginia. Large waves will also cause significant beach erosion.

Low Pressure System Prompts Tropical Storm Warnings for Mid-Atlantic Coast

A low pressure system formed over the Atlantic Ocean off the coast of the southeast U.S. on Thursday morning. The U.S. National Hurricane Center designated the low pressure system as Potential Tropical Cyclone Sixteen and issued Tropical Storm Warnings for portions of the Mid-Atlantic coast. At 2:00 p.m. EDT on Thursday the center of Potential Tropical Cyclone Sixteen was located at latitude 29.0°N and longitude 75.9°W which put it about 430 miles (690 km) south of Cape Hatteras, North Carolina. Potential Tropical Cyclone Sixteen was moving toward the north 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 1012 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Cape Fear, North Carolina to Fenwick Island, Delaware. The Tropical Storm Warning included Albemarle Sound and Pamlico Sound. A Tropical Storm Warning was also in effect for Chesapeake Bay south of Smith Point.

A low pressure system formed over the Atlantic Ocean off the coast of the southeast U.S. on Thursday morning. The low pressure system formed as an extratropical cyclone. There was a large counterclockwise circulation around the low pressure system. There was not a well formed, distinct low level center of the circulation. Thunderstorms were occurring in a band that wrapped around the eastern and northern side of the low pressure systems. Fragmented bands in other parts of the circulation consisted primarily of showers and lower clouds.

Potential Tropical Cyclone Sixteen will move through an environment favorable for intensification of an extratropical cyclone during the next 24 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 28°C. It will move under the eastern side of an upper level trough over the eastern U.S. The upper level trough will produce southwesterly winds that will blow across the top of Potential Tropical Cyclone Sixteen. Those winds will cause moderate vertical wind shear. However, the flow of air in the upper levels will also provide divergence aloft that will pump mass away from the surface low pressure system. The removal of mass will cause the surface pressure to decrease. Potential Tropical Cyclone Sixteen is likely to intensify during the next 24 hours. The low pressure system could make a transition to a tropical storm later on Friday when it moves over the warmer water in the Gulf Stream.

The upper level trough over the eastern U.S. will steer Potential Tropical Cyclone Sixteen toward the north during the next 24 hours. On its anticipated track Potential Tropical Cyclone will approach the coast of North Carolina on Friday night. The low pressure system will bring gusty winds and locally heavy rain to eastern North Carolina, eastern Virginia, southeastern Maryland and southern Delaware. The gusty winds will blow water toward the coast. A storm surge of up to 5 feet (1.5 meters) could occur in some locations. Large waves will cause significant beach erosion. Locally heavy rain could cause flash floods in some locations.

Elsewhere over the Atlantic Ocean, Hurricane Nigel was speeding toward the northeast as it passed southeast of Newfoundland. At 11:00 a.m. EDT on Thursday the center of Hurricane Nigel was located at latitude 42.2°N and longitude 45.0°W which put it about 505 miles (815 km) southeast of Cape Race,, Newfoundland. Nigel was moving toward the northeast at 30 m.p.h. (48 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).

Winds to hurricane force extended out 20 miles (30 km) from the center of Lisa in the northern side of Lisa. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Hurricane Lisa will move south of a high pressure system over the Gulf of Mexico. The high pressure system will steer Lisa toward the west-northwest during the next 36 hours. On its anticipated track, Hurricane Lisa will move inland over Belize on Wednesday evening. Lisa will bring strong winds and heavy rain to Belize. The strongest winds are north of the center of Hurricane Lisa. Lisa could bring strong winds to Belize City during the next several hours. Hurricane Lisa will also cause a storm surge of up to 8 feet (2.5 meters) along the coast of Belize. Lisa will weaken steadily as it moves farther inland. The center of Lisa will move over northern Guatemala during Wednesday night. Lisa could reach the Bay of Campeche as a tropical depression on Thursday night. Hurricane Lisa will drop heavy rain over Belize, northern Guatemala and southeastern Mexico. Heavy rain could cause flash floods in some locations.

Elsewhere over the Atlantic Ocean, former Tropical Storm Martin intensified to a hurricane south of Newfoundland. At 5:00 p.m. EDT on Wednesday the center of Hurricane Martin was located at latitude 37.1°N and longitude 47.6°W which put it about 720 miles (1160 km) south-southeast of Cape Race, Newfoundland. Martin was moving toward the northeast at 31 m.p.h. (50 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 974 mb.

Tropical Storm Warnings were in effect for the entire North Coast of Honduras, the North Coast of Guatemala, and the portion of the coast from Chetumal to Punta Allen, Mexico.

A U.S. Air Force Reserve Hurricane Hunter plane found that former Tropical Storm Lisa had strengthened to a hurricane on Wednesday morning. The inner end of a rainband wrapped most of the way around the center of Hurricane Lisa. Other bands of showers and thunderstorms were revolving around the core of Lisa’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane. The circulation around Hurricane Lisa was small. Winds to tropical storm force extended out 70 miles from the center of Lisa.

Hurricane Lisa will move through an environment favorable for intensification during the next few hours. Lisa will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the axis of an upper level ridge over the Caribbean Sea. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Hurricane Lisa is likely to strengthen during the next few hours.

Hurricane Lisa will move south of a high pressure system over the Gulf of Mexico. The high pressure system will steer Lisa toward the west during the next 24 hours. On its anticipated track, Hurricane Lisa will make landfall on the coast of Belize in a few hours. Lisa will bring strong winds and heavy rain to Belize. Heavy rain could cause flash floods in some locations. Hurricane Lisa will also cause a storm surge of up to 8 feet (2.5 meters) along the coast of Belize.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Lisa was located at latitude 16.7°N and longitude 83.3°W which put it about 330 miles (530 km) east of Belize City, Belize. Lisa was moving toward the west at 15 m.p.h. (24 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 1000 mb.

Hurricane Warnings were in effect for Belize and the Bay Islands, Honduras. A Hurricane Watch was in effect for the portion of the coast from Chetumal to Puerto Costa Maya, Mexico. Tropical Storm Warnings were in effect for the entire North Coast of Honduras, the coast of Guatemala, and the portion of the coast from Chetumal to Punta Herrero, Mexico.

Tropical Storm Lisa strengthened on Tuesday. The inner end of a rainband wrapped around the center of Lisa’s circulation. Other bands of showers and thunderstorms were revolving around the core of Tropical Storm Lisa. Storms near the core generated upper level divergence that pumped mass away from the tropical storm. The circulation around Tropical Storm Lisa was small. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Storm Lisa will move through an environment favorable for intensification during the next 24 hours. Lisa will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the axis of an upper level ridge over the Caribbean Sea. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Storm Lisa is likely to strengthen to a hurricane during the next 12 hours. Lisa could intensify more rapidly after an inner core with an eye and an eyewall forms.

Tropical Storm Lisa will move south of a high pressure system over the Gulf of Mexico. The high pressure system will steer Lisa toward the west during the next 36 hours. On its anticipated track, the center of Tropical Storm Lisa will be north of Honduras on Tuesday night. Lisa will approach Belize on Wednesday afternoon. Tropical Storm Lisa will be a hurricane when it approaches Belize. Tropical Storm Lisa could bring gusty winds and locally heavy rain to the north coast of Honduras. Lisa will bring strong winds and heavy rain to Belize. Heavy rain could cause flash floods in some locations. Lisa will also cause a storm surge along the coast of Belize.

Elsewhere over the Atlantic Ocean, Tropical Storm Martin developed east-northeast of Bermuda. At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Martin was located at latitude 35.4°N and longitude 54.5°W which put it about 630 miles (1010 km) east-northeast of Bermuda. Martin was moving toward the east at 15 m.p.h. (24 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 991 mb.

Tropical Storm Peter Passes Northeast of Leeward Islands

Tropical Storm Peter passed northeast of the Leeward Islands on Monday. At 11:00 a.m. EDT on Monday the center of Tropical Storm Peter was located at latitude 19.5°N and longitude 60.9°W which put it about 170 miles (275 km) northeast of the Leeward Islands. Peter was moving toward the west-northwest at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 50 m.p.h. (75 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1007 mb.

An upper level trough north of Puerto Rico and an upper level ridge east of the Leeward Islands were interacting to produce strong southwesterly winds that were blowing across the circulation around Tropical Storm Peter. Those winds were causing strong vertical wind shear. The low level center of circulation was clearly evident on visible satellite images and it was surrounded by showers and lower clouds. Thunderstorms were occurring in bands on the eastern and northern periphery of the circulation around Tropical Storm Peter. Bands in the western and southern parts of Peter consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 125 miles (200 km) in the northeastern quadrant of Peter’s circulation. The winds in the other parts of the circulation were blowing at less than tropical storm force.

Tropical Storm Peter will move through an environment unfavorable for intensification during the next 36 hours. Peter will move over water where the Sea Surface Temperatures are near 29˚C. However, the upper level trough and the upper level ridge will continue to produce strong vertical wind shear. The strong wind shear will inhibit intensification. Tropical Storm Peter could weaken gradually during the next 36 hours.

Tropical Storm Peter will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Peter toward the west-northwest during the next 36 hours. On its anticipated track Tropical Storm Peter will pass north of the Northern Leeward Islands, the Virgin Islands and Puerto Rico.

Elsewhere over the Atlantic Ocean, Tropical Storm Rose moved away from the Cabo Verde Islands. At 11:00 a.m. EDT on Monday the center of Tropical Storm Rose was located at latitude 17.3°N and longitude 33.4°W which put it about 620 miles (1000 km) west-northwest of the Cabo Verde Islands. Rose was moving toward the 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 1007 mb.
