SATELLITE ANALYSIS AND TRENDS...THE BLENDED TPW PRODUCT INDICATED
AN INCREASED PLUME OF MOISTURE ASSOCIATED WITH THE TROPICAL WAVE HAS
ARRIVED IN THE AREA. SAN JUAN`S 12Z SOUNDING CONFIRM THE MOISTURE WITH
PWATS AT 2.23 INCHES AND INDICATE CAPE OF 3200 J/KG IS PRESENT ACROSS
THE REGION. LATEST INFRARED SATELLITE AND RADAR IMAGERY SHOW MOST OF THE
SHOWERS/CONVECTION REMAIN TO THE NORTH OF PUERTO RICO BUT SHOW SOME COLD
CLOUD TOPS ACROSS MOST OF EASTERN PUERTO RICO. VISIBLE IMAGERY SHOWS
SOME OVERSHOOTING CLOUD TOPS WHILE FREQUENT LIGHTNING STRIKES ARE SEEN
IN THE GLD OVER NORTHEAST PUERTO RICO.
.
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 1235-1835Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...ANOMALOUS MOISTURE (THREE TO FOUR STANDARD
DEVIATIONS ABOVE NORMAL) IS SEEN WITH GOOD INSTABILITY ACROSS THE
REGION. DURING THE REST OF THE MORNING, EASTERN PUERTO RICO AND COASTAL
WATERS COULD EXPERIENCE PASSING SHOWERS WITH ISOLATED CONVECTION. THIS
AFTERNOON AS DAYTIME HEATING PEAKS, LOCAL TERRAIN EFFECTS AND
LOW-LEVEL EASTERLY FLOW SHOULD CONTRIBUTE TO THE MAIN THREAT AREA
BEING WESTERN PUERTO RICO. PARTS OF CENTRAL AND NORTHERN  PUERTO RICO
COULD ALSO EXPERIENCE BOUTS OF CONVECTION, BUT THE THREAT SHOULD BE MORE
ISOLATED. SHOWERS AND ISOLATED CONVECTION ARE STILL POSSIBLE THROUGH THE
OUTLOOK FOR THE U.S. VIRGINS ISLANDS AND COASTAL WATERS AS THE TROPICAL
WAVE MOVES ACROSS THE AREA. EXPECT COVERAGE OF SHOWERS AND CONVECTION
TO DIMINISH AS THE TROPICAL WAVE MOVES OUT OF THE AREA LATER TODAY.
