SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 09/21/21 1947Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES16 CH02 VIS_0.64, GOES16 CH09 WV_6.9, TJSJ SOUNDING, TJUA RADAR, HRW_PR_ARW/ SAMBUCCI . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...HEAVY RAINFALL FROM THE OUTER BANDS OF TROPICAL STORM PETER . SATELLITE ANALYSIS AND TRENDS...THE LATEST GOES16 VISIBLE AND WATER VAPOR IMAGERY OBSERVED TROPICAL STORM PETER TO THE NORTHEAST OF THE REGION AIDING IN ENHANCING SYNOPTIC LIFT AND STRONG LOW LEVEL MOISTURE TRANSPORT OVER THE ISLAND. THE LATEST RADAR LOOPS FROM TJUA AS A RESULT OF THE FAVORABLE DYNAMICS OBSERVED A STRONG MOISTURE AXIS OF CONVECTIVE ACTIVITY OVER WESTERN, CENTRAL, AND EASTERN INTERIOR PUERTO RICO. THE LATEST RAOB SOUNDING DATA FROM TJSJ IS SUPPORTIVE OF A MOIST AND UNSTABLE ENVIRONMENT THROUGH THE REGION WITH EARLIER 12Z DATA SHOWING SBCAPE VALUES GREATER THAN 3250 J/KG AS WELL AS A LIFTING INDEX OF -7 CELSIUS, AND TPW GREATER THAN 2.00". MESONET DATA FROM EARLIER THIS AFTERNOON OBSERVED GREATER THAN 1.00" OF RAINFALL THUS FAR OVER PARTS OF NORTHWESTERN 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 2000-0200Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...THE DEVELOPMENT AND CONTINUATION OF CONVECTIVE ACTIVITY OVER THE ISLAND IS HIGHLY LIKELY OVER THE REST OF THIS AFTERNOON AND THROUGH MOST OF THE EARLY EVENING HOURS. LIGHT NORTHEASTERLY WINDS OBSERVED IN EARLIER 12Z SOUNDING DATA FROM TJSJ AHEAD OF THE OUTER BANDS OF PETER SHOULD NOW RESULT IN SLOW MOVING CONVECTIVE ACTIVITY WHICH COULD LIKELY RESULT IN FLOODING OVER PARTS OF THE ISLAND ESPECIALLY OVER THE INTERIOR AND MOUNTAINOUS TERRAIN OF THE ISLAND. THE HEAVY RAINFALL AND FLOOD RISK LIKELY WILL BE LESS SEVERE IN THE LATE EVENING HOURS AND OVERNIGHT TONIGHT. THE HEAVY RAINFALL AND FLOODING IS LIKELY THE REST OF TODAY OVER WESTERN, CENTRAL, AND EASTERN INTERIOR PUERTO RICO. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
