Discussion and 48-hour Outlook 

At 11:00 a.m. EDT (1500 UTC), the center of sandy was located near latitude 40.2 north, and longitude 78.4 west. The post-tropical cyclone was moving toward the west at 10 mph (16 km/h).  Sandy has slowed in forward motion and is expected to continue its westward track across southern Pennsylvania this afternoon, and should take a turn toward western New York tonight.  The cyclone will move into Canada on Wednesday. 

Maximum sustained winds are near 45 mph (72 km/h) with higher gusts. 

Minimum central pressure is 983 mb (29.0 inches). 

Hazards

 Wind. Strong winds will continue into this afternoon over portions of the Northeast, central/southern Appalachians, and across the Great Lakes.

 Storm Surge. Even though water levels along the coast have been subsiding, the combination of storm surge and the tide could still cause normally dry areas near the coast to be flooded by rising waters, especially in areas approaching high tide.  The water could reach the following depths above ground at the time of high tide: 

  • Pamlico and Albemarle Sounds, 2 to 4 ft.
  • Upper and middle Chesapeake Bay and Delaware Bay, 2 to 4 ft.
  • Delmarva Peninsula northward through the Jersey Shore, 1 to 3 ft.
  • New York northward to Massachusetts, 1 to 2 ft.

 Due to strong and persistent northerly winds, coastal flooding along portions of the Great Lakes is possible. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. The surge could be accompanied by large and dangerous waves along portions of the coast exposed to the Atlantic Ocean.  For information specific to your area, please see products issued by your local National Weather Service Office. 

Rainfall. Additional rainfall accumulations of up to an inch are expected from the eastern Great Lakes, across the mid-Atlantic and into southern New England, bringing storm total precipitation amounts of 6 to 10 inches across the mid-Atlantic region from southern New Jersey across   Delaware, Maryland, northern Virginia and southern Pennsylvania.  Storm total precipitation

Amount of 2 to 5 inches likely across western Pennsylvania, eastern Ohio and western New York.  Precipitation amounts of 1 to 2 inches possible over eastern Maine. 

Snowfall. Snowfall storm totals of 2 to 3 feet are expected in the mountains of West Virginia into far western Maryland. Snowfall storm totals of 1 to 2 feet are expected in the mountains of southwestern Virginia into eastern portions of Kentucky, in the mountains along the North Carolina/Tennessee border. 

Surf. Dangerous surf conditions will continue from Florida through New England for the next couple of days.
