perhaps noaa can splain a bit:
LOW PRESSURE JUST SOUTH OF LONG ISLAND EARLY THIS MORNING WILL
INTENSIFY STRONGLY AS IT MOVES NORTHWARD THROUGH EASTERN NEW
ENGLAND TODAY. THE STORM WILL THEN MOVE THROUGH EASTERN CANADA
TONIGHT AND WEDNESDAY. THE STRONG CIRCULATION AROUND THE LOW WILL
CAUSE WINDS TO INCREASE DRAMATICALLY THIS MORNING OVER THE COASTAL
WATERS AND DELAWARE BAY. WEST TO NORTHWEST WINDS WILL GUST AS HIGH
AS 50 TO 55 KNOTS AT TIMES THIS AFTERNOON AND THIS EVENING BEFORE
DIMINISHING LATER TONIGHT. SEAS WILL RESPOND TO THE INCREASING
WINDS, AND WAVE HEIGHTS ON THE OCEAN WILL BUILD TO 5 TO 9 FEET
TODAY. WAVES ON DELAWARE BAY WILL BUILD TO 2 TO 4 FEET TODAY, AND
TO AROUND 5 FEET NEAR THE MOUTH OF DELAWARE BAY.
THE STRONG OFFSHORE FLOW WILL ALSO CAUSE BLOW-OUT TIDES AROUND THE
TIMES OF LOW TIDE LATE THIS AFTERNOON, TONIGHT, AND WEDNESDAY FOR
NEW JERSEY AND DELAWARE COASTAL WATERS, AS WELL AS ON DELAWARE
BAY. THIS WILL OCCUR ESPECIALLY ALONG EAST-FACING SHORELINES.
