ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/25/18 0459Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 EIR-VIS-WV 0430Z / AMSU-RAIN 04Z / MIMIC-TPW2 03Z; BAK . LOCATION...HAWAII/MAUI/MOLOKAI/LANAI... . ATTN WFOS...HFO... ATTN RFCS...APRFC... . EVENT...TROPICAL STORM LANE HEAVY RAIN BANDS . SATELLITE ANALYSIS AND TRENDS...LAST GOES-15 VIS IMAGERY SHOWS LANE'S LOW AND MID-LEVEL CIRCULATIONS DECOUPLING. MID-LEVEL CIRCULATION IS SLOWLY MOVING NE AND HAS SPAWNED AN INTENSE BAND OF CONVECTION IN THE LAST 2 HRS WITH IR CLOUD TOPS AS COLD AS -80 C JUST TO THE S AND W OF THE ERN PART OF THE ISLAND CHAIN. RAINFALL RATES EXCEEDING 1.50"/HR ARE ASSOCIATED WITH THIS BAND PER THE AMSU-RAIN PRODUCT. OVER THE BIG ISLAND, TORRENTIAL RAINS CONTINUE ASSOCIATED WITH A PERSISTENT AREA OF COLD IR CLOUD TOPS ALONG THE NORTHEAST COAST WITH PHTO RECEIVING 2.20" 02-03Z. 00Z RAOB FROM PHTO RECORDED A PWAT OF 2.47" AND A MUCAPE OF OVER 1600 J/KG SO ATMOSPHERE IS PRIMED FOR CONTINUED VERY HEAVY RAINFALL. . SHORT TERM OUTLOOK VALID 0500Z-1100Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...DUE TO THE SLOW MOVEMENT OF LANE, EXCESSIVE RAINFALL TOTALS ARE LIKELY TO CONTINUE OVER THE BIG ISLAND AS STRONG AND VERY MOIST SSE FLOW WILL REMAIN UNABATED. OFFSHORE HEAVY RAIN BAND IS ALREADY MOVING OVER THE WESTERN PART OF THE BIG ISLAND PER LATEST RADAR LOOP AND SHOULD BEGIN TO OVERSPREAD MAUI, MOLOKAI, AND LANAI IN THE NEXT 1-2 HR WITH AMOUNTS OVER 5" POSSIBLE. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
