Center of Tropical Storm Debby Near Savannah

The center of Tropical Storm Debby was near Savannah, Georgia on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Debby was located at latitude 31.9°N and longitude 81.0°W which put the center about 15 miles (25 km) south of Savannah, Georgia.  Debby was moving toward the east-northeast at 6 m.p.h. (10 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 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Altamaha Sound Georgia to Surf City, North Carolina.  The Tropical Storm Warning included Charleston, South Carolina.

A Tropical Storm Watch was in effect for the portion of the coast from Surf City to Beaufort Inlet, North Carolina.

Tropical Storm Debby continued to drop heavy rain over parts of South Carolina and eastern Georgia.  The airport at Charleston, South Carolina reported 8.11 inches (206 mm) of rain during the past 24 hours.  Valdosta, Georgia received 2.75 inches (70 mm) of rain.  Sarasota, Florida reported 11.06 inches (281 mm) of rain from Debby.  Gainesville, Florida received 6.80 inches (173 mm) of rain.  Jacksonville, Florida reported 4.70 inches (119 mm) of rain.  It is likely that higher rainfall totals occurred in some places where bands moved persistently over the same locations.

Southerly winds blowing around the eastern side of Tropical Storm Debby were pushing water toward the coast of South Carolina.  There were numerous reports of water in streets in Charleston, South Carolina.

Tropical Storm Debby weakened during the day it spent moving slowly across northern Florida and southeastern Georgia.  Drier air wrapped around the western and southern sides of Debby’s circulation.  Bands in the southwestern and southeastern quadrants of Tropical Storm Debby consisted primarily of showers and lower clouds.  Showers and thunderstorms were occurring in bands in the outer parts of the northeastern and northwestern quadrants of Tropical Storm Debby.  There were also showers and lower clouds near the center of Debby.

The distribution of wind speeds in Tropical Storm Debby was also asymmetrical.  Winds to tropical storm force extended out 205 miles (330 km) in the eastern side of Debby.  Those winds were occurring in bands in the outer parts of Debby’s circulation.  The winds in the parts of Debby’s circulation that were over land were blowing at less than tropical storm force.

Tropical Storm Debby will move into an environment favorable for intensification.  Debby will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the southeastern U.S.  The upper level winds are weak near the center of the ridge and there will be little vertical wind shear.  The drier air in the southern part of Debby’s circulation will inhibit intensification.  Tropical Storm Debby is likely to intensify slowly during the next 24 hours.

Tropical Storm Debby will be in an area where the steering winds are weak during the next 24 hours.  Debby is likely to move slowly toward the east-northeast during the rest of Tuesday.  A high pressure system located east of Tropical Storm Debby is forecast to strengthen on Wednesday.  That high pressure system will steer Debby slowly toward the north on Wednesday.  On its anticipated track, the center of Tropical Storm Debby could approach the coast of South Carolina on Wednesday night.

Tropical Storm Debby will continue to drop heavy rain on parts of South Carolina, North Carolina and eastern Georgia.  Since Debby will move slowly, persistent heavy rain is likely to cause floods.

Flood Watches are in effect for parts of South Carolina, North Carolina and eastern Georgia.

Southerly winds blowing around the eastern side of Tropical Storm Debby will continue to push water toward the coast of South Carolina and North Carolina.  Debby could cause a storm surge of up to 6 feet (1.8 meters).

A Storm Surge Warning is in effect for the portion of the coast from Altamaha Sound, Georgia, to South Santee River, South Carolina.

A Storm Surge Watch is in effect for the portion of the coast from South Santee River, South Carolina to Cape Fear, North Carolina.

Hurricane Debby Moves Inland over North Florida

Hurricane Debby moved inland over North Florida on Monday morning.  At 8:00 a.m. EDT on Monday the center of Hurricane Debby was located at latitude 29.9°N and longitude 83.4°W which put the center about 20 miles (30 km) southeast of Perry, Florida.  Debby was moving toward the north-northeast at 10 m.p.h. (16 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 979 mb.

A Tropical Storm Warning was in effect for the portion of the coast from St. Augustine, Florida to South Santee River, South Carolina.

The center of Hurricane Debby made landfall near Steinhatchee, Florida on Monday morning.  The maximum sustained wind speed in Hurricane Debby was 80 m.p.h. (130 km/h) at the time of landfall.  Thunderstorms were occurring in bands in the northern and eastern parts of Debby’s circulation.  Bands in the southern and western parts of Hurricane Debby consisted primarily of showers and lower clouds.

The distribution of winds speeds around Hurricane Debby was also asymmetrical at the time of landfall.  Winds to hurricane force extended out 25 miles (40 km) in the eastern side of Debby’s circulation.  Winds to tropical storm force extended out 140 miles (225 km) in the eastern half of Hurricane Debby.  Winds to tropical storm force extended out 70 miles in the western half of Debby’s circulation.

Hurricane Debby will move around the western end of a high pressure system over the western Atlantic Ocean.  The high pressure system and an upper level trough over the eastern U.S. will steer Debby toward the east-northeast during the next 24 hours.  On its anticipated track, Hurricane Debby will move across northeastern Florida and southeastern Georgia.  The steering currents could weaken during the  middle of the week and Debby could meander near the coast of South Carolina.

Hurricane Debby will weaken to a tropical storm as it moves inland over northeastern Florida and southeastern Georgia.  Debby will continue to produce strong winds and electricity outages are likely.  Hurricane Debby will drop heavy rain over northeastern Florida and southeastern Georgia.  Widespread flooding could occur.  If Debby stalls near South Carolina later this week, then prolonged heavy rain could occur.

Flood Watches are in effect for parts of Florida, Georgia and South Carolina.

Hurricane Debby will continue to cause a storm surge along the coast of west Florida while southwest winds blow water toward the coast.  The storm surge could be as high as 10 feet (3 meters) along parts of the coast.

A Storm Surge Warning is in effect for the portion of the coast from Longboat Key to Indian Pass, Florida.  A Storm Storm Warning is also in effect for the portion of the coast Mouth of the St. Mary’s River, Georgia to South Santee River, South Carolina.

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.
