ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/23/18 0545Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 EIR-WV 05Z / MIMIC-TPW2 04Z / AMSU-PWAT 0530Z; BAK . LOCATION...HAWAII/MAUI... . ATTN WFOS...HFO... ATTN RFCS...APRFC... . EVENT...HURRICANE LANE OUTER RAIN BANDS . SATELLITE ANALYSIS AND TRENDS...THE INFLUENCE OF LANE'S CIRCULATION IS GRADUALLY INCREASING OVER THE BIG ISLAND AND MAUI PER LATEST GOES-15 EIR/RADAR LOOPS. TRANSIENT COLDER CLOUD TOPS ALONG WITH SEVERAL LTG STRIKES HAVE BEEN NOTED OVER THE N COAST OF THE BIG ISLAND IN THE LAST FEW HRS. DEEP EASTERLY FLOW HAS BEEN ESTABLISHED AS A VERY HIGH PWAT PLUME EVIDENT ON THE MIMIC-TPW2 PRODUCT EXTENDS FROM OVER THE BIG ISLAND/MAUI TO SEVERAL HUNDRED MILES TO THE E. 00Z RAOB FROM PHTO MEASURED A 2.50" PWAT VALUE WHICH IS THE HIGHEST VALUE ON RECORD FOR AUGUST FOR THIS LOCATION AND 5TH HIGHEST OVERALL. THIS VALUE IS SUPPORTED BY THE AMSU-PWAT PRODUCT WHICH INDICATES PWATS UP TO 2.50" OVER THE BIG ISLAND CURRENTLY. . SHORT TERM OUTLOOK VALID 0540-1140Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...EXPECT HEAVY RAINFALL TO CONTINUE DURING THE OUTLOOK PERIOD WITH 2-4" LIKELY N AND E FACING AREAS OF THE BIG ISLAND WITH FLASH FLOODING CONTINUING AS GROUND IS SATURATED FROM THE 2-4" THAT FELL IN THE PREVIOUS 6 HRS. RAINFALL RATES SHOULD INCREASE OVER MAUI WITH SMALL MID-LVL CIRCULATION APPARENT ON PHMO AND PHKM RADARS JUST S OF THE ISLAND POSSIBLY ENHANCING AMOUNTS. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
