ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 09/28/18 2043Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 2030Z HANNA . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...AKRFC... . EVENT...LOCALIZED HEAVY RAIN THREAT . SATELLITE ANALYSIS AND TRENDS...ALTHOUGH ENVIRONMENT DOES NOT APPEAR TO BE QUITE AS CONDUCIVE TO ORGANIZED HEAVY RAIN THREAT TODAY COMPARED TO YESTERDAY, THERE STILL REMAINS A THREAT OF LOCALIZED HEAVY RAIN THROUGHOUT THE DAY WITHIN ANOMALOUS MOISTURE AXIS AND CONVERGENT BOUNDARY THAT EXTENDS THROUGH THE CENTRAL ISLANDS. THE MOST RECENT WV IMAGERY WAS SHOWING THAT BEST JET DYNAMICS APPEAR TO BE IN THE PROCESS OF SHIFTING NE OF THE ISLAND AS BASE OF MID LEVEL TROF N OF THE REGION HAS BEGUN TO MOVE E OF 145W. STILL THOUGH, THERE WAS A WEAKER JET WITH SHEAR AXIS THAT EXTENDED WSW FROM THE BASE OF THE TROF NE OF THE AREA TO W OF THE ISLANDS THAT MAY HELP IN AIDING IN SOME WEAK SYNOPTIC ASCENT. BEST ACTIVITY OVER THE PAST HOUR OR SO WAS OVER PORTIONS OF NW OAHU WHERE AUTOMATED GOES ESTIMATES WERE SUGGESTING RAINFALL RATES AROUND 1.0"/HR ALTHOUGH MOST RECENT GOES IMAGE SUGGEST THAT CONVECTIVE CORE HAS WEAKENED RAPIDLY WITHIN THE PAST 30 MINUTES. TOWARDS THE EVENING HOURS WOULD ALSO EXPECT THAT LOCALIZED HEAVY RAIN THREAT OVER E PORTIONS OF THE BIG ISLAND AS INCREASING EASTERLIES AND DEEPER MOISTURE ASSOCIATED WITH 97C S OF THE ISLANDS BEGINS TO APPROACH AFTER 0Z. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
