Tropical Storm Elsa prompted the issuance of warnings and watches for the East Coast of the U.S. on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Elsa was located at latitude 32.1°N and longitude 82.3°W which put it about 55 miles (90 km) west of Savannah, Georgia. Elsa was moving toward the north-northeast at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 55 m.p.h. (90 km/h). The minimum surface pressure was 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Altamaha Sound, Georgia to Great Egg Inlet, New Jersey. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound. A Tropical Storm Watch was in effect for the portion of the coast from Great Egg Inlet to Sandy Hook, New Jersey. A Tropical Storm Watch was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Watch was also in effect for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts including Block Island, Nantucket, Martha’s Vineyard, and Cape Cod.

The center of Tropical Storm Elsa was moving across eastern Georgia on Wednesday night. Heavy rain was spreading across South Carolina. Rainbands on the eastern side of Elsa’s circulation were producing winds to tropical storm force over the Atlantic Ocean. NOAA buoy 41008 at Grays Reef reported a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 47 m.p.h. (76 km/h). The circulation around Tropical Storm Elsa was still well defined. A distinct low pressure system was evident on the surface map, radar and satellite displays. Storms on the eastern side of Elsa generated upper level divergence that pumped mass away to the northeast of the tropical storm.

An upper level trough over the Great Lakes will steer Tropical Storm Elsa toward the northeast during the next 48 hours. On its anticipated track Tropical Storm Elsa will move across South Carolina on Thursday morning and North Carolina on Thursday afternoon. Elsa could be over eastern Virginia on Thursday evening and near Long Island by Friday morning. Even though the center of Tropical Storm Elsa will be over land for another 18 to 24 hours, bands on the eastern side of the circulation could produce tropical storm force winds over the Atlantic Ocean and along the East Coast of the U.S. Elsa will also drop locally heavy rain over South Carolina, eastern North Carolina and eastern Virginia. Gusty winds and heavy rain could cause sporadic power outages. Heavy rain could also cause flash floods in some locations.
