MARINE WEATHER DISCUSSION FOR GULF OF MEXICO...CARIBBEAN SEA
AND SOUTHWEST NORTH ATLC S OF 31N W OF 55W.

UPPER LEVELS...
STRONG CUT OFF LOW CENTERED NEAR NEW YORK CITY AND THE 
ASSOCIATED LONGWAVE TROUGH EAST OF FLORIDA DOMINATES THE 
ATLANTIC AREA. RIDGE IS OVER THE GULF OF MEXICO.  A STRONG 
SHORTWAVE TROUGH WILL DAMPEN THE GULF RIDGE BEGINNING TUESDAY AS 
IT MOVES OVER EAST TEXAS AND ACROSS THE NORTH GULF OF MEXICO 
COAST THROUGH WEDNESDAY. ON THURSDAY THE SHORTWAVE WILL COMBINE 
WITH THE TROUGH OVER THE ATLANTIC TO PRODUCE A LONGWAVE TROUGH 
EAST OF 85W THROUGH SATURDAY. RIDGE WILL BUILD OVER THE GULF 
WEST OF 85W BEHIND THE SHORTWAVE.

SURFACE...
COLD FRONT OVER THE SOUTHEAST PART OF THE AREA WILL PASS 
SOUTHEAST OF THE AREA TUESDAY.  STRONG LOW PRESSURE ASSOCIATED 
WITH THE CUT OFF LOW WILL PRODUCE GALE FORCE WESTERLY WINDS IN 
THE NORTH PART OF THE ATLANTIC AREA THROUGH TUESDAY.

THE SURFACE LOW ASSOCIATED WITH THE STRONG UPPER SHORTWAVE 
MOVING ALONG THE NORTH GULF COAST WILL FOLLOW A SIMILAR TRACK 
WITH WESTERLY WINDS IN THE 20 TO 25 KT RANGE SOUTH OF THE LOW 
AND NORTH OF ABOUT 25N. THE SYSTEM WILL STRENGTHEN IN THE 
ATLANTIC AS IT APPROACHES BERMUDA AND GALE FORCE SOUTHWESTERLY 
WINDS ARE EXPECTED BUT THESE WINDS WILL BE JUST EAST OF THE 
OFFSHORE AREA.

SURFACE HIGHS ARE WEAK AS WOULD BE EXPECTED FOR APRIL.

THE WINDS IN THE CARIBBEAN WILL BE LESS THAN NORMAL BECAUSE 
PRESSURES WILL BE LOW NORTH OF THE CARIBBEAN AREA.
