EVENT...DEEP MOISTURE OVER THE ISLANDS AND SHEAR FOR
INSTABILITY...LOCALIZED HVY RAIN POSSIBLE OVERNIGHT...
.
SATELLITE ANALYSIS AND TRENDS...DEEP PW MOISTURE HAS COME ACROSS THE
ISLANDS FROM THE SOUTHEAST THE PAST 24HRS WITH HIGHEST MICROWAVE PWS
OF 2.1" MOSTLY FROM THE CENTRAL/EAST PART OF PUERTO RICO EASTWARD.
PRIMARY HVY RAIN HAS BEEN EAST OF PUERTO RICO AND MAY STAY THAT WAY MOST
OF THE NIGHT...BUT AM CONCERNED THAT QUITE A BIT OF SHEAR FROM SATELLITE
WINDS OVER THE ISLAND COULD HELP DEVELOP MORE ORGANIZED HVY RAIN SHOWERS
THAT COULD WORK INLAND TO PRODUCE BRIEF HVY RAINS OF 1-2 INCHES PER HR.
UPPER LEVEL WINDS ARE LIGHT...SO MOVEMENT OF INDIVIDUAL CELLS COULD BE
SLOWED.   A NEGATIVE IS THE OBVIOUS LACK OF HEATING AND HIGH EQUILIBRIUM
LEVEL TEMPS...BUT WILL HAVE TO KEEP AN EYE ON LOW LEVEL CONVERGENCE.
PRIMARY THREAT FOR FIRST HALF OF NIGHT IS EAST THIRD OF PUERTO RICO AND
ISLANDS TO THE EAST WHERE PW VALUES WILL BE HIGHEST.    WILL CONTINUE
TO MONITOR...
