HAZARDS
-------
WIND...STRONG WINDS WILL CONTINUE THROUGH WEDNESDAY MORNING 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:

UPPER AND MIDDLE CHESAPEAKE BAY 1 TO 3 FEET.

THE FRESHWATER FLOOD WATERS ORIGINATING IN THE UPPER POTOMAC FROM
THE RAINS OF SANDY WILL START TO IMPACT THE TIDAL
POTOMAC...RESULTING IN A SIGNIFICANT FLOOD STARTING THIS EVENING
AND CONTINUING THROUGH FRIDAY AFTERNOON.

ELSEWHERE ELEVATED WATER LEVELS ALONG THE COAST OF NORTH CAROLINA
TO MASSACHUSETTS WILL SUBSIDE OVERNIGHT AND ON WEDNESDAY.

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. THIS WILL BRING STORM TOTAL
PRECIPITATION AMOUNTS OF 6 TO 12 INCHES ACROSS THE MID-ATLANTIC
REGION FROM SOUTHERN NEW JERSEY ACROSS 
DELAWARE...MARYLAND...NORTHERN VIRGINIA AND SOUTHERN PENNSYLVANIA.
 ADDITIONAL PRECIPITATION AMOUNTS OF 1 TO 2 INCHES ARE EXPECTED
OVER EASTERN MAINE THROUGH WEDNESDAY.

SNOWFALL...ADDITIONAL SNOWFALL ACCUMULATIONS OF 5 TO 10 INCHES ARE
EXPECTED IN THE MOUNTAINS OF WEST VIRGINIA INTO FAR WESTERN
MARYLAND...WITH ISOLATED AMOUNTS UP TO 15 INCHES.  THIS WILL BRING
STORM SNOWFALL TOTALS TO 2 TO 3 FEET OVER PORTIONS OF THE CENTRAL
APPALACHIANS...AND 1 TO 2 FEET OVER EASTERN PORTIONS OF KENTUCKY
AND 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.
