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 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.

The minimum surface pressure was 994 mb.

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.

The minimum surface pressure was 1001 mb.

Tropical Storm Nicole dropped heavy rain over parts of the southeastern U.S. on Friday morning. Heavy rain was falling over eastern Tennessee and eastern Kentucky. Bands in the far eastern side of Nicole’s circulation contained thunderstorms that were dropping heavy rain over parts of eastern South Carolina, eastern North Carolina and southeastern Virginia. Easterly winds blowing around the northern side of Nicole’s circulation were enhancing convergence and rising motion ahead of a cold front moving toward the eastern U.S. The enhanced convergence and rising motion was contributing to rain that was falling in the region from Delaware to Ohio.

The cold front approaching the eastern U.S. and an upper level trough over the central U.S. will steer Tropical Depression Nicole quickly toward the north-northeast during Friday. On its anticipated track the center of Tropical Depression Nicole will be over West Virginia by Friday evening. Heavy rain falling over parts of the southeastern U.S. and Appalachians could cause flooding. Flood Watches were in effect for parts of northern South Carolina, western North Carolina and southern Virginia. There could be enough low level wind shear for tornadoes to develop in the bands on the far eastern side of the circulation around Tropical Depression Nicole. A Tornado Watch was in effect for eastern South Carolina, eastern North Carolina and southeastern Virginia.

Subtropical Storm Nicole Forms East of the Bahamas

Subtropical Storm Nicole formed east of the Bahamas on Monday morning. At 7:00 a.m. EST on Monday the center of Subtropical Storm Nicole was located at latitude 25.9°N and longitude 69.1°W which put it about 520 miles (835 km) east of the Northwestern Bahamas. Nicole was moving toward the north-northwest at 14 m.p.h. (22 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 1002 mb.

A Tropical Storm Watch was in effect for the Northwestern Bahamas.

A large low pressure system over the Atlantic Ocean east of the Bahamas exhibited more organization on Monday morning and the National Hurricane Center designated the system as Subtropical Storm Nicole. The circulation around Subtropical Storm Nicole exhibited a complex structure that is fairly common late in the hurricane season. The surface center of circulation was northeast of an upper level low east of Florida. The strongest winds near the surface were occurring far to the east of the surface center. Winds to tropical storm force extended out 275 miles (445 km) in the eastern side of Subtropical Storm Nicole. The winds in the western side of Nicole’s circulation were blowing at less than tropical storm force.

Subtropical Storm Nicole will move through an environment that is favorable for a gradual transition to a tropical storm. Nicole will move over water where the Sea Surface Temperatures are near 28˚C. The upper level low east of Florida will produce southerly winds that will blow across the top of the surface center of Subtropical Storm Nicole during the next 24 hours. Those winds will cause moderate vertical wind shear and the wind shear will inhibit intensification. Nicole will move into a region where the upper level winds are weaker on Tuesday and the wind shear will diminish. Subtropical Storm Nicole is likely to strengthen gradually during the next 24 hours. Nicole will move over warmer water when it moves over the Gulf Stream on Wednesday. Subtropical Storm Nicole is likely to make a transition to a tropical storm when it moves over the warmer water. Nicole could intensify to a hurricane when it moves over the warmer water.

The upper level low east of Florida will steer Subtropical Storm Nicole toward the northwest during the next 24 hours. A surface high pressure system currently over the Great Lakes will move over the East Coast of the U.S. and the western Atlantic Ocean. The high pressure system will block Nicole from moving toward the north. The high pressure system will steer Nicole toward the west-southwest on Tuesday and Wednesday. On its anticipated track Subtropical Storm Nicole could reach the Northwestern Bahamas on Wednesday morning. Nicole could reach the coast of Southeast Florida on Wednesday night. Nicole could be a hurricane when it reaches Florida. Nicole is likely to bring strong, gusty winds and locally heavy rain to the Northwestern Bahamas and southern Florida. The winds in the northern side of Nicole will blow water toward the coast of Florida and the Southeast U.S. Those winds will cause a storm surge and serious beach erosion when Nicole moves toward the coast.
