STORM SURGE: THE COMBINATION OF STORM SURGE AND THE TIDE WILL CAUSE
NORMALLY DRY AREAS NEAR THE COAST TO BE FLOODED BY RISING WATERS
MOVING INLAND FROM THE SHORELINE. THE WATER COULD REACH THE
FOLLOWING HEIGHTS ABOVE GROUND SOMEWHERE IN THE INDICATED AREAS IF
THE PEAK SURGE OCCURS AT THE TIME OF HIGH TIDE...
HATTERAS INLET, NC TO MANASQUAN INLET, NJ...1-3 FT
CHESAPEAKE BAY AND TIDAL RIVERS...1-3 FT
DELAWARE BAY...1-3 FT
BEAUFORT INLET, NC TO HATTERAS INLET, NC...1-2 FT
NEUSE, BAY, PAMLICO, AND PUNGO RIVERS...1-2 FT
ALBEMARLE AND PAMLICO SOUND...1-2 FT
THE DEEPEST WATER WILL OCCUR ALONG THE IMMEDIATE COAST IN AREAS OF
ONSHORE WINDS, WHERE THE SURGE WILL BE ACCOMPANIED BY DANGEROUS
WAVES. SURGE-RELATED FLOODING DEPENDS ON THE RELATIVE TIMING OF THE
SURGE AND THE TIDAL CYCLE, AND CAN VARY GREATLY OVER SHORT
DISTANCES. FOR INFORMATION SPECIFIC TO YOUR AREA, PLEASE SEE
PRODUCTS ISSUED BY YOUR LOCAL NATIONAL WEATHER SERVICE FORECAST
OFFICE.
WIND: GUSTY WINDS TO TROPICAL STORM FORCE ARE STILL POSSIBLE NEAR
THE COASTS OF NORTH CAROLINA AND VIRGINIA DURING THE NEXT FEW HOURS.
RAINFALL: OPHELIA IS EXPECTED TO PRODUCE THE FOLLOWING ADDITIONAL
RAINFALL THROUGH SUNDAY NIGHT:
PORTIONS OF THE MID-ATLANTIC FROM NORTH CENTRAL NORTH CAROLINA
THROUGH NEW JERSEY...1 TO 3 INCHES WITH ISOLATED HIGHER TOTALS UP
TO 5 INCHES.
ACROSS SOUTHEASTERN NEW YORK THROUGH SOUTHERN NEW ENGLAND...1 TO 3
INCHES.
THIS RAINFALL MAY PRODUCE LOCALLY CONSIDERABLE FLASH, URBAN, AND
SMALL STREAM FLOODING IMPACTS, PARTICULARLY ACROSS THE MID ATLANTIC
REGION FROM NORTH CAROLINA TO NEW JERSEY. ISOLATED RIVER FLOODING IS
POSSIBLE IN AREAS OF HEAVIER RAINFALL.
SURF: SWELLS GENERATED BY OPHELIA WILL CONTINUE TO AFFECT MUCH OF
THE EAST COAST OF THE UNITED STATES THROUGH THE WEEKEND. THESE
SWELLS ARE LIKELY TO CAUSE LIFE-THREATENING SURF AND RIP CURRENT
CONDITIONS. PLEASE CONSULT PRODUCTS FROM YOUR LOCAL WEATHER OFFICE.
TORNADOES: A TORNADO OR TWO MAY OCCUR THROUGH TONIGHT ACROSS PARTS
OF THE MID-ATLANTIC COAST.
