AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
330 PM AST MON OCT 26 2015

.SYNOPSIS...LONG WAVE TROUGH CONTINUE TO DOMINATE THE WEATHER
CONDITIONS. THIS UPPER TROUGH JUST NORTHWEST OF PUERTO RICO WILL
MAINTAIN VERY UNSTABLE ENVIRONMENT ACROSS PUERTO RICO AND THE
U.S. VIRGIN ISLANDS THROUGH AT LEAST ON TUESDAY. SURFACE TROUGH
NORTH OF THE AREA IS INDUCING A GENTLE SOUTHERLY FLOW ACROSS THE
ISLANDS...RESPONSIBLE FOR CARRYING ABUNDANT MOISTURE ACROSS THE
NORTHEAST CARIBBEAN REGION. WEATHER CONDITIONS IMPROVE SOMEWHAT BY
MIDWEEK AS EASTERLY TRADES RETURN TO THE AREA.

&&

.DISCUSSION...VERY MOIST AND UNSTABLE ENVIRONMENT CONTINUES TO
INDUCE THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS ACROSS THE

RICO WHERE PARTLY CLOUDY SKIES WERE OBSERVED TODAY. THIS ALLOW
TEMPERATURES TO RISE TO THE UPPER 80S OVER WESTERN PR...REACHING
THE CONVECTIVE TEMP ALLOWING SHOWERS AND THUNDERSTORMS TO DEVELOP
OVER THIS AREA. THE REST OF PUERTO RICO REMAINED FAIRLY STABLE AS
TEMPS DID NOT REACH THE CONVECTIVE TEMP OF 86 DEGREES...KEEPING
THE SHOWERS AND THUNDERSTORMS OVER WATERS.

DEEP TROPICAL MOISTURE WILL CONTINUE TO SURGE ACROSS THE LOCAL REGION
THROUGH AT LEAST TUESDAY. LOOKS LIKE THE REST OF TODAY AND TONIGHT
ADDITIONAL SHOWERS AND THUNDERSTORMS WILL ADVECT OVER THE ISLANDS
FROM THE CARIBBEAN WATERS. HIGH POTENTIAL OF FLOODING RAINS CONTINUES
ACROSS PUERTO RICO AND THE U.S. VIRGIN ISLANDS THROUGH TUESDAY DUE
TO VERY UNSTABLE CONDITIONS ASSOCIATED WITH THE AFOREMENTIONED UPPER
LOW NORTHWEST OF THE REGION COMBINED WITH ABUNDANT MOISTURE AND
ALREADY SATURATED SOILS. THEREFORE...THE FLASH FLOOD WATCH HAS BEEN
EXTENDED THROUGH TUESDAY EVENING.

WEATHER CONDITIONS IMPROVE SOMEWHAT BY MIDWEEK WHEN DRIER AIR WILL
ADVECT AT MID LEVELS AND THE UPPER LEVEL TROUGH GRADUALLY FILLS.
