SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/24/16 1727Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES 13: 1715Z JAW
.
LOCATION...PUERTO RICO...U.S. VIRGIN ISLANDS
.
ATTN WFOS...SJU...
ATTN RFCS...SERFC
.
EVENT...UPDATE TO PREVIOUS MESSAGE REGARDING STRONG TROPICAL WAVE
APPROACHING THE AREA
.
SATELLITE ANALYSIS AND TRENDS...LATEST INFRARED IMAGERY SHOWS A SLIGHT
WARMING TREND TO THE MAIN CONVECTION ASSOCIATED WITH THE TROPICAL
WAVE. COOLING CLOUD TOPS WERE SEEN ACROSS NORTHERN AND EASTERN PUERTO
RICO, SAINT CROIX, CULEBRA AND NEARBY COASTAL WATERS.  THE LIGHTNING
STRIKE DENSITY PRODUCT SHOWED CLUSTERS OF LIGHTNING ACROSS THE NORTHWEST
AND CENTRAL PUERTO RICO AS CONVECTION IS ALREADY BEGINNING ACROSS WESTERN
PUERTO RICO. SAN JUAN`S 12Z SOUNDING SHOWED EVEN BETTER MOISTURE THAN
WAS INDICATED BY THE BLENDED TPW PRODUCT, WITH PWATS AT 2.67 INCHES. THE
SOUNDING ALSO SHOWED AN UNSTABLE ATMOSPHERE PRESENT WITH CAPE OVER
2000 J/KG.
.
SHORT TERM OUTLOOK VALID 1730-2330Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GIVEN THE GREAT MOISTURE, EXPECT SHOWERS WITH
SOME EMBEDDED CONVECTION TO IMPACT MOST OF THE AREA THIS AFTERNOON INTO
THE EVENING HOURS. THE GREATEST THREAT FOR MODERATE TO LOCALLY HEAVY
RAIN WOULD BE THE U.S. VIRGIN ISLANDS,  EASTERN PUERTO RICO AND WITH
AREAS EXPERIENCING CONVECTION. TRAINING IS ALSO A THREAT WITH SHOWERS
MOVING OVER ALREADY SATURATED SOILS. ANY BOUNDARIES THAT MAY FORM COULD
PROVIDE A FOCUS FOR REDEVELOPMENT AND LOCAL EFFECTS COULD HELP PLAY A
ROLE TO HELP ENHANCE CONVECTION AS THE WAVE NEARS THE AREA.
