ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 03/03/20 0529Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: 200303/0500 GOES17 CH13 IR_10.4 . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...AKRFC... . EVENT...HEAVY RAINFALL POSSIBLE ACROSS MAUI AND OAHU ISLANDS . SATELLITE ANALYSIS AND TRENDS...THE LATEST GOES17 IR IMAGERY OBSERVED A REGION OF COLD/HIGH CLOUD TOPS TO THE NORTHEAST OF MAUI AND OAHU ISLANDS IN THE MIDDLE PART OF THE STATE. RADAR TRENDS OBSERVED ISOLATED HEAVIER SHOWERS AND THUNDERSTORMS OVER EASTERN MAUI AND NORTHERN OAHU ISLAND. THE LATEST UA RAOB SOUNDING DATA FROM PHTO OBSERVED INCREASING TPW OVER 1.00" WITH MOIST UNSTABLE SOUTHERLY FLOW OVER THE STATE. SBCAPE VALUES OBSERVED GREATER THAN 2400 J/KG SUPPORTING STRONG LOW LEVEL MOISTURE TRANSPORT AND AN UNSTABLE ENVIRONMENT IN THE REGION. . 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 0530-1030Z...LOW CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...STRONG LOW LEVEL MOISTURE AND AN UNSTABLE ENVIRONMENT IS LIKELY TO PERSIST WITH THE PROGRESSION OF AN UPPER LEVEL MOVING EAST TO WEST TOWARDS THE STATE OVER THE FORECAST PERIOD. THE UPPER LEVEL LOW WILL HELP TO ENHANCE AND PROMOTE CONVECTIVE ACTIVITY BUT CONFIDENCE IS LOW WITH THE PLACEMENT AND PERSISTENT OF THE STRONG CONVECTION OVER THE FORECAST PERIOD. HEAVY RAINFALL AND ISOLATED FLOOD THREAT IS POSSIBLE ESPECIALLY NORTH WEST OF HONOLULU ON OAHU ISLAND AND IN EASTERN PARTS OF MAUI ISLAND OVER THE FORECAST PERIOD. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
