MIAMI, Florida -- As of 8:00 a.m. Eastern Daylight Time on Saturday, October 27, 2012, NOAA's National Hurricane Center in Miami, Florida, has issued its tropical weather outlook due to the presence of Hurricane Sandy in the Atlantic Ocean off the east coast of Florida.
Hurricane Sandy, briefly Tropical Storm Sandy earlier this morning, is located 335 miles southeast of Charleston, South Carolina, or about 225 miles east-northeast of Cape Canaveral, Florida, with maximum sustained winds of 75 miles per hour - making Sandy a Category 1 Hurricane. Hurricane Sandy is moving to the north-northeast at 10 miles per hour.
Hurricane Sandy's expanded wind field is affecting Florida, Georgia, South Carolina, and North Carolina weather this morning. Hurricane-force winds extend up to 100 miles, and Tropical storm-force winds extend up to 450 miles, from the center of Hurricane Sandy.
Hurricane Sandy is forecast to weaken to a tropical storm later today as it moves northeastward in the open Atlantic Ocean less than 300 miles off the Florida east coast this morning, and less than 250 miles off the North Carolina coast on Sunday night.
Tropical Storm Sandy is expected to strengthen during the Hurricane Sandy hook on Monday, becoming a Category 1 Hurricane once again, before it makes landfall on or around Delaware on Tuesday, October 30, 2012.
New York City, Philadelphia, and Washington D.C. are all within the current landfall forecast cone of uncertainty from North Carolina to Connecticut - which is causing some forecasters to use the term "Frankenstorm" for the northeastern U.S. Hurricane Sandy landfall just before Halloween on October 31, 2012.
NOAA warns that a storm surge of 3 to 5 feet is possible for the Tropical Storm Warning area in the Bahamas, 1 to 3 feet within the Warning Area for the Florida coast, 3 to 5 feet within the Warning Area for North Carolina, and 2 to 4 feet for the remainder of North Carolina and Southeast Virginia, including Chesapeake Bay. Warning areas are displayed in the above image.
Elsewhere in the Atlantic, tropical storm formation is not expected during the next 48 hours.
