STORM SURGE...EVEN THOUGH WATER LEVELS ALONG THE COAST HAVE BEEN
SUBSIDING...THE COMBINATION OF STORM SURGE AND THE TIDE COULD

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.
