AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
255 PM AST SAT SEP 20 2003

THE MORNING WAS VERY ACTIVE ESPECIALLY OVER THE WATERS SOUTH OF
PUERTO RICO WITH SOME THUNDERSTORMS GROWING BEYOND THE TROPOPAUSE
HEIGHT.

THE VIGOROUS MID TO UPPER LOW BEEN MENTIONED BY PREVIOUS FORECASTERS
SINCE FEW DAYS AGO...IS LOCATED OVER THE AREA AND FORECAST TO MOVE
WESTWARD UNTIL SUNDAY AND THEN BECOMING STATIONARY OVER THE
DOMINICAN REPUBLIC. THE BROAD SURFACE TROUGH EAST OF THE WINDWARDS
EARLY THIS AFTERNOON IS EXPECTED TO MOVE NORTHWESTWARD INTERACTING
WITH THE UPPER LOW TO INCREASE THE LIKELIHOOD OF SHOWERS SUNDAY AND
INTO MONDAY. THERE ARE CHANCES FOR WEATHER TO BECOME SEVERE SUNDAY
AND MONDAY.

TUESDAY...WINDS ARE EXPECTED TO CONTINUE LIGHT BUT WITH A NORTHEAST
COMPONENT. HOW STRONG THE DIURNAL CONVECTION WILL BE TUESDAY WILL
DEPEND ON HOW MUCH CLOUD COVER WE GET. BELIEVE THAT EXPECTED WEATHER
FROM PREVIOUS DAYS WILL PRODUCE A THICK CIRRUS LAYER WHICH WILL
INHIBIT THE DAY HEATING DECREASING THE CHANCE FOR SHOWERS. WITH THIS
THOUGH I SEE AN IMPROVEMENT IN WEATHER CONDITIONS TUESDAY.

SJU...
.PR...NONE.
.VI...NONE.

EQUIPMENT...NO PROBLEMS AT THIS TIME.
