ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 06/23/19 1123Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: 190623/1100Z . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...AKRFC... . EVENT...HEAVY RAINFALL RISK...190623/1100Z GOES15 WV_6.5 IMAGERY . SATELLITE ANALYSIS AND TRENDS... A UPPER LEVEL LOW NORTH OF THE ISLAND IS TRANSPORTING DEEPER MOISTURE INTO KAUAI COUNTY. THE NORTHERN MOST HAWAIIAN ISLANDS ARE LOCATED IN THE TAIL END VICINITY OF THE UPPER LEVEL LOW WHERE SHORTWAVE ENERGY IS ENHANCING DYNAMIC LIFT. THE LATEST SATELLITE IMAGERY USING GOES IR OBSERVED COOLER HIGHER CLOUD TOPS DEVELOPING SOUTHWEST OF THE ISLANDS. THE LATEST RADAR LOOPS OBSERVED HEAVIER SHOWERS OVER NI'HAU ISLAND PROGRESSING FROM THE SOUTH OF THE ISLAND,OVER THE ISLAND, AND THEN OFF TOWARDS THE NORTH. TPW IN THE REGION IS GREATER THAN 1.25" AND SBCAPE VALUES ARE QUIET HIGH ABOVE 2000 J/KG WITH NEGATIVE LIFTING INDEX AS WELL SUGGESTING A MOIST AND UNSTABLE PROFILE OVER KAUAI COUNTY. . 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 1100-1400Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...THE HEAVIER SHOWERS ARE LIKELY TO CONTINUE TO PROGRESS OFF TOWARDS THE NORTH AND THEN PROGRESS NORTH EAST OVER KAUAI ISLAND ALONG WITH THE UPPER LEVEL FLOW LATER ON IN THE FORECAST PERIOD. MOISTURE CONTENT AND TPW IS LIKELY TO INCREASE OVER THE NORTHERN HAWAIIAN ISLANDS LEADING TO AN INCREASED THREAT FOR REPEATED CONVECTION WITH HEAVIER SHOWERS AND THUNDERSTORMS LIKELY AFFECTING THE REGION. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
