SATELLITE ANALYSIS AND TRENDS...THE LATEST SATELLITE MOISTURE ANALYSIS
OVER PUERTO RICO INDICATES THE POTENTIAL FOR HEAVY RAINFALL WITH BLENDED
TPW AMOUNTS 1.7"-2.0" OF POTENTIAL HOURLY RAINFALL AMOUNTS AND RECENT
TRENDS OF DEVELOPING CONVECTION IN THE CENTRAL PART OF THE ISLAND OF
PUERTO RICO WITH HOURLY RATES OF 2.13 INCH/HOUR.
ELSEWHERE ALONG THE HIGHER TERRAIN FROM EAST TO WEST RATES AVERAGE
0.50 INCHES/HR.
SURFACE MOISTURE CONVERGENCE FIELDS ARE NOT FAVORABLE. SATELLITE WATER
VAPOR IMAGES INDICATE A STREAM OF MID LEVEL MOISTURE STREAMING IN FROM THE
SW TOWARD PUERTO RICO WHILE LOW LEVEL SURFACE WINDS ARE COMING IN FROM
AN EASTERLY DIRECTION. AREAS OF HIGHER TERRAIN WILL BE MORE SUSCEPTIBLE
FOR LOCALIZED FLASH FLOODING UNTIL THIS EVENING WHEN THE SUN BECOMES
LESS OF A FACTOR IN PROVIDING AN ELEVATED HEAT SOURCE FOR GENERATING
POSITIVE VERTICAL VELOCITIES ASSOCIATED WITH THE LATEST CONVECTION.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 2015-0000Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...AFTERNOON CONVECTION SHOWS A RECENT HISTORY WITH

A LOCALIZED RISK OF FLASH FLOODING IS MAINLY OVER THE HIGHER TERRAIN OF
PUERTO RICO IN THE CENTRAL HIGHLANDS FROM E-W.
