Re: Caribbean - C America - Watching Atl East of Lesser Antilles
A PERSISTENT LOW IN THE WEST CENTRAL CARIBBEAN IS KEEPING VERY
DEEP MOISTURE OVER THE AREA. TROUGHING WILL EXTEND NORTHEAST OF
THIS AND OVER HISPANIOLA...KEEPING AREAS OF HIGH HUMIDITY OVER
PUERTO RICO...AND THE U.S. VIRGIN ISLANDS. A DEEP POLAR TROUGH
DIGGING INTO THE WESTERN ATLANTIC WILL SUSTAIN GOOD VERTICAL LIFT
OVER THE LOCAL AREA THAT WILL HELP TO GENERATE AREAS OF HEAVY
RAINFALL NOW THROUGH WEDNESDAY. CURRENT INDICATIONS ARE THAT THE
HEAVIEST RAINS WILL OCCUR MONDAY AND TUESDAY.
HYDROLOGICAL CONDITIONS ACROSS PUERTO RICO ARE BECOMING MORE
SUSCEPTIBLE TO FLASH FLOODING WITH SATURATED SOILS AND ABOVE
NORMAL STREAM AND RIVER FLOW DUE TO THE PERSISTENT RAINS OVER THE
PAST FEW WEEKS. ANY ADDITIONAL RAINS OVER THE COMING DAYS WILL
ONLY AGGRAVATE THIS SITUATION. WHILE ALL AREAS ARE AT RISK OF
EXPERIENCING SOME FLOODING...AREAS NORTH OF THE CORDILLERA CENTRAL
ARE AT GREATEST RISK OF EXPERIENCING THE MOST SIGNIFICANT FLOODING
DUE TO THE PRESENT STATE OF THE SOIL CONDITIONS. ADDITIONALLY
PLUMES OF SHOWERS FROM THE SOUTHWEST MAY SET UP OVER THE U.S.
VIRGIN ISLANDS ON MONDAY AND TUESDAY THAT COULD PRODUCE FLOODING
IN AREA GUTS.
THIS PRODUCT WILL BE UPDATED SUNDAY MORNING OR WHEN CONDITIONS
CHANGE...WHICHEVER IS EARLIER.
