Post Tropical Cyclone Andrea Project Path Update





Miami, Florida --  At 5:00 p.m. Eastern Daylight Time on Friday, June 7, 2013, NOAA's National Hurricane Center issued its tropical weather outlook due to the presence of former Tropical Storm Andrea, now Post-Tropical Cyclone Andrea, that is racing up the U.S. East Coast.


NOAA's storm tracker and spaghetti models are in agreement that the projected path of Post-Tropical Cyclone Andrea will go through southeast Virginia this evening, and then head just east of the Washington, D.C. metro area tonight.  


Andrea is forecast to skirt along southeast Delaware and the New Jersey shore early Saturday morning, then up through Long Island, New York, eastern Connecticut, Rhode Island and Boston, Massachusetts.



 

The latest location of Post-Tropical Cyclone Andrea is approximately 100 miles west-southwest of Norfolk, Virginia, with maximum sustained winds of 45 miles per hour, with higher gusts.  Andrea is moving to the northeast at 28 miles per hour.  

Post-Tropical Cyclone Andrea, the first named storm of the 2013 Hurricane season, is bringing rain and the possibility of localized flooding and tornadoes to parts of northeastern North Carolina, southeastern Virginia, and southeastern Maryland today.  


Andrea's tropical storm force winds extend up to 230 miles mainly to the east from the center.  This broad wind area brings the possibility of gale force winds from Virginia to Atlantic Canada tonight through Sunday.


A Tropical Storm Warning is in effect for the U.S. East Coast from north of Surf City, North Carolina to Cape Charles Light, Virginia, Pamlico and Albemarie Sounds, and Lower Chesapeake Bay south of New Point Comfort, Virginia.


A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.



Local Flash Flood Warnings, Flood Warnings, Coastal Flood Advisories, Tornado Watches and Warnings, and other hazardous weather advisories are being issued across the Mid-Atlantic and Northeastern states by the National Weather Service.
