SATELLITE ANALYSIS AND TRENDS...A TROPICAL WAVE SOUTH OF PR IS CLOSING
IN ON PUERTO RICO, THE DOMINICAN REPUBLIC AND HAITI.  MAIN IMPACTS
WILL LIKELY BE THE WEST OVER DR AND HAITI, BUT LINGERING STORMS AND
LOCALLY HEAVY RAINFALL ARE POSSIBLE FOR PR OVERNIGHT.  THE LATEST
AMSU PASS FROM 1620Z DEPICTS AERIAL AVERAGE RAINRATES AT LEAST 1.50
IN/HR JUST SOUTH OF PR ASSOCIATED WITH THE TROPICAL WAVE ENCROACHING
ON THE SOUTHERN SHORE.  DESPITE THE MODERATELY HEAVY RAINRATES FROM THE
EARLIER AMSU PASS, GOES-16 IR IMAGERY DEPICTS RAPIDLY WARMING CLOUD TOPS,
SIGNIFYING THE DETERIORATION OF THE STRONGEST CONVECTION.  ADDITIONALLY,
GOES-16 WV IMAGERY ALSO SUGGESTS DRYING PATTERN WITH CLOUD FEATURES
PRIOR TO MOVEMENT OVER PR, POTENTIALLY LIMITING THE AMOUNT OF RAINFALL
PRODUCTION.  GPS BLENDED PW PRODUCT SUGGESTS VALUES FALL WITHIN 1.5-2"
OVER THE ISLAND, AND A STREAM OF HIGHER PW, TOPPING 2", ASSOCIATED WITH
THE WAVE IS FLOWING OVER THE DOMINICAN REPUBLIC AND HAITI.  THIS TROPICAL
MOISTURE MAY ENABLE LOCALLY HEAVY RAINFALL RATES.
.
SHORT TERM OUTLOOK VALID 0126-0721Z...LOW CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...SCATTERED THUNDERSTORMS CONTAINING LOCALLY
HEAVY RAINFALL ARE POSSIBLE AS REMNANT DEVELOPMENT ASSOCIATED WITH THE
TROPICAL WAVE TO THE SOUTH COME ASHORE.  RAIN RATES WITHIN CELLS THAT
DEVELOP CAN BE HEAVY AND POSE FF THREAT TO URBAN AREAS AND REGIONS WITH
STEEP TERRAIN, ESPECIALLY CONSIDERING WET ANTECEDENT CONDITIONS.
