AND SOUTHWEST NORTH ATLC S OF 31N W OF 55W.

GULF OF MEXICO...
TROPICAL DEPRESSION FIVE AT 26.4N84.5W PACKING WINDS TO 30 GUST 
TO 40 KT EXPECTED TO DRIFT NW INTO MID GULF TODAY AND INTENSIFY 
OVER N CENTRAL GULF NEAR LOUISIANA COAST LATE TONIGHT THEN MOVE 
INLAND OVER LOUISIANA THU.  ALTHOUGH SYSTEM LACKS MUCH OF NEEDED 
CONVECTION...ITS PACE HAS SLOWED DOWN AND WITH FAVORABLE  
CONDITIONS IS EXPECTED TO REACH TROPICAL STORM FORCE BEFORE 
LANDFALL THU.  STRONGER WINDS REMAIN MAINLY IN NORTHERN 
SEMICIRCLE AND AT A SLOWER MOVEMENT MAY DEVELOP ENOUGH FETCH TO 
BUILD SEAS WELL ABOVE MODEL GUIDANCE WHICH REMAINS UNCOMFORTABLY 
LOW AT THIS TIME.  RAINFALL AMOUNTS NEAR THE COAST COULD ALSO BE 
AN ISSUE AS SYSTEM SLOWS DOWN ITS NW PACE.  WINDS AND SEAS 
RAPIDLY DECREASE AS SYSTEM MOVES INLAND.  ELSEWHERE MOSTLY LIGHT 
TO GENTLE BREEZE ACROSS REMAINDER OF GULF.

ATLC SURFACE RIDGE ALONG 30N MAINTAIN E-SE MODERATE BREEZE S OF 
25N E OF 75W THROUGH WED.  RIDGE DRIFTS S AND WEAKENS WITH 
MODERATE SE BREEZE S OF 27N AND LIGHT S-SW BREEZE N OF 27N THU 
THROUGH SAT.  RIDGE SHIFTS S TO AROUND 26N SUN AS WEAK FRONT/ 
TROUGH STALLS JUST N OF 31N...WITH W-SW WINDS INCREASING TO 
FRESH BREEZE OVER FAR NE PORTION OF AREA.

CARIBBEAN SEA...
TWO TROPICAL WAVES CROSS CARIBBEAN AND TROPICAL ATLC ZONES 
THROUGH NEXT FIVE DAYS.  NEVERTHELESS NEITHER ONE CARRIES 
SIGNIFICANT STRENGTH TO STIR THE WINDS OR SEAS FROM THEIR 
LETHARGIC CONDITION.  ONLY SECOND WAVE MAY HAVE MINOR IMPACT 
NEAR COAST OF COLOMBIA TO INCREASE WINDS TO A MODERATE ELY 
BREEZE SAT AND SUN.
