AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 1235 PM AST WED AUG 27 2003 IN GENERAL AGREEMENT WITH PREVIOUS FORECAST THOUGH AND BELIEVE THERE IS NO NEED FOR AN UPDATE AT THIS TIME. /RIVERA CLIMO FORECAST WORKS BEST FOR THE NEXT SEVERAL DAYS TO COME AS THERE ARE NO LARGE SCALE FEATURES OF CONCERN TO REALLY WRITE HOME ABOUT. PRECIPITABLE WATER FELL FROM A WHOPPING 2.47 MONDAY NIGHT...DOWN TO 2.02 LAST NIGHT...AND THIS WILL CONTINUE TO SLOWLY FALL TODAY. HOWEVER...MORE SUNSHINE THIS AFTERNOON WILL LIKELY ALLOW CONVECTION TO FIRE ACROSS WESTERN PUERTO RICO. THE LOW LEVEL FLOW IS SLOWLY SHIFTING TO A MORE EASTERLY DIRECTION...SO THE BEST CHANCE FOR THUNDERSTORMS THIS AFTERNOON IS ACROSS WESTERN INTERIOR PUERTO RICO. THEN...TONIGHT JUST A FEW HIT AND MISS SHOWERS OVER EASTERN PORTIONS OF THE FORECAST AREA. THIS TREND WILL BE REPEATED OVER THE NEXT SEVERAL DAYS. HIGH PRESSURE WILL CONTINUE WEAKENING OVER THE CENTRAL AND EASTERN ATLANTIC...RESULTING IN A CONTINUATION OF A LIGHTER THAN NORMAL WIND FLOW LOCALLY...AND THUS SEAS OF MAINLY 3 FEET OR LESS. /GREGORIA SJU... .PR...NONE. .VI...NONE. EQUIPMENT...NO PROBLEMS AT THIS TIME.
