ZCZC NFDSPENES ALL SPENES VIZ000-PRZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 03/15/20 0131Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: 200315/0100 GOES16 CH 09 WV_6.9 . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...HEAVY RAINFALL WITH THUNDERSTORM ACTIVITY FOR EASTERN PUERTO RICO . SATELLITE ANALYSIS AND TRENDS...THE LATEST GOES16 WATER VAPOR IMAGERY OBSERVED AN UPPER LEVEL LOW WELL TO THE NORTHEAST OF THE ISLAND. THE UPPER LEVEL LOW HOWEVER IS DESTABILIZING THE ENVIRONMENT AND ENHANCING SYNOPTIC LIFT ESPECIALLY ACROSS EASTERN PARTS OF THE ISLAND WHERE SCATTERED SHOWERS AND THUNDERSTORMS WITH ISOLATED HEAVY CONVECTIVE CELLS HAVE BEEN OBSERVED IN RECENT RADAR LOOPS. THE LATEST UA RAOB SOUNDING DATA FROM TJSJ OBSERVED TPW VALUES GREATER THAN 1.40" AND SBCAPE GREATER THAN 1800 J/KG WHICH IS SUPPORTING THE MOIST AND UNSTABLE ENVIRONMENT OVER THE ISLAND. . 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 0130-0530Z...LOW CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...THE SCATTERED CONVECTIVE ACTIVITY PRESENT IS LIKELY TO BE BRIEF AND CONTINUE TO PROGRESS ALONG WITH THE MODERATE TRADE WINDS OF AROUND 15KTS FROM THE NORTHEAST TO THE THE SOUTHWEST OVER THE PERIOD. ISOLATED POCKETS OF HEAVY RAINFALL AND FLOODING COULD BE POSSIBLE OVER THE NEXT FEW HOURS ESPECIALLY IN REGIONS OF HIGHER TERRAIN ACROSS PARTS OF THE ISLAND WHERE CONVECTIVE ACTIVITY COULD PROGRESS OVER THE FORECAST PERIOD. THE HEAVY RAINFALL RISK APPEARS LOW BUT PRESENT OVER THE FORECAST PERIOD. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
