.DISCUSSION...ACTIVE WEATHER TODAY FOR BOTH PUERTO RICO AND THE
U.S. VIRGIN ISLANDS AS A MOIST AND UNSTABLE SOUTH TO SOUTHEAST
WIND FLOW KEPT ADVECTING MOISTURE ACROSS THE ISLANDS. THE MOISTURE
HAS BEEN FEEDING FOR DAYS INTO A BROAD CIRCULATION OVER THE WEST
ATLANTIC AND HAS COMBINED WITH THE RIGHT AMOUNT OF MID AND UPPER
LEVEL VENTILATION TO PRODUCE PERIODS OF LOCALLY HEAVY RAINS.

AT LEAST THROUGH MIDNIGHT WOULD ANTICIPATE SHOWERS AND A FEW
THUNDERSTORMS CONTINUING ACROSS PUERTO RICO AND USVI. LATER THIS
EVENING THE ACTIVITY SHOULD DECREASE BUT STILL TO AFFECT
SOUTHEAST PUERTO RICO AND THE USVI. FOR FRIDAY LESS SHOWERS ARE
EXPECTED BUT BY LATE FRIDAY INTO SATURDAY A TROPICAL WAVE
APPROACHING 55W SHOULD ENTER INTO THE PICTURE BRINGING MOISTURE
AND INSTABILITY THAT SHOULD PERSIST SATURDAY AND SUNDAY.
AFTER MONDAY NIGHT GFS MODEL SUGGESTS DECREASING MOISTURE WITH
EAST TO SOUTHEAST WINDS PREVAILING THRU FRIDAY BUT UPPER LEVEL
WINDS WILL ALLOW FOR THUNDERSTORMS TO DEVELOP EACH DAY AND
INCREASE TOWARDS THURSDAY AS THE FLOW ALOFT BECOMES MORE WESTERLY
AND SOME PERTURBATIONS MOVE EAST.

&&

.AVIATION...SHOWERS AND A FEW THUNDERSTORMS WILL CONTINUE TO MOVE
NORTH NORTHWEST ACROSS THE USVI AND PUERTO RICO THROUGH NEXT 24
HOURS AS MOIST UNSTABLE SOUTHEAST WIND FLOW FEEDS INTO LOW PRESSURE
COMPLEX WELL TO THE NORTH OF THE WEST ATLANTIC. MOST OF THE SHOWERS
AND THUNDERSTORMS WILL PRODUCING BRIEF IFR CONDITIONS OVER WATER
NEAR USVI AND OVER INLAND PUERTO RICO NEAR THE EASTERN ONE THIRD AND
ALONG THE NORTHWEST AS THEY MOVE OFFSHORE. LIGHT SOUTH TO SOUTHEAST
FLOW WILL CONTINUE ADVECTING MOISTURE INTO LOCAL AREA AND MID TO
