ZCZC NFDSPENES ALL SPENES PRZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 05/23/19 1634Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: ####################### . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...################## . SATELLITE ANALYSIS AND TRENDS...############## . A TROPICAL WAVE TO THE NORTH OF ISLAND IS SLOWLY PROGRESSING SOUTH. THE LATEST GOES16 WV IMAGERY INDICATED AN INCREASE IN WV WITH COOLER HIGH CLOUD TOPS JUST NW OF THE ISLAND THAT ARE NOW MOVING INTO THE AREA. THE INTERACTION BETWEEN TROPICAL EASTERLIES AND UPPER LEVEL FLOW OUT OF THE WEST WITH SUBTROPICAL JET MOISTURE FEED BEING ENHANCED BY SYNOPTIC LIFT SOUTH OF THE TROPICAL WAVE WILL INCREASE HEAVY RAINFALL RISK AND CONVECTIVE THUNDERSTORM ACTIVITY ACROSS WESTERN PORTIONS OF THE ISLAND LATER IN THE DAY. INSTABILITY IN THE REGION WITH SBCAPE VALUES GREATER THAN 1000 J/KG AND TPW VALUES GREATER THAN 1.5" SUPPORT HEAVY RAINFALL RISK WITH FAVORABLE DYNAMICS IN THE REGION. THE THREAT IS EXPECTED TO DIMINISH LATER IN THE FORECAST PERIOD. .
