550 WTNT34 KNHC 150840 TCPAT4 BULLETIN Remnants Of Isaac Advisory Number 31 NWS National Hurricane Center Miami FL AL092018 500 AM EDT Sat Sep 15 2018 ...NOAA HURRICANE HUNTER PLANE INDICATES ISAAC HAS DISSIPATED... ...THIS IS THE LAST ADVISORY... SUMMARY OF 500 AM EDT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...14.8N 70.8W ABOUT 260 MI...420 KM SSW OF SANTO DOMINGO DOMINICAN REPUBLIC ABOUT 455 MI...730 KM ESE OF KINGSTON JAMAICA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...W OR 270 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the remnants of Isaac were located near latitude 14.8 North, longitude 70.8 West. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. The remnants of Isaac will likely continue to produce gusty winds and occasional heavy rains while moving westward across the central and western Caribbean during the next few days. The estimated minimum central pressure is 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Isaac is expected to produce rainfall totals of 2 to 4 inches with isolated maximum amounts of 6 inches across the south-central portion of the Dominican Republic, southern Haiti, and most of Jamaica. This rainfall, especially in mountainous terrain, may cause life-threatening flash floods. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and available on the Web at https://ocean.weather.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Zelinsky

559 WTNT44 KNHC 150841 TCDAT4 Remnants Of Isaac Discussion Number 31 NWS National Hurricane Center Miami FL AL092018 500 AM EDT Sat Sep 15 2018 A NOAA Hurricane Hunter aircraft investigated Isaac over the past few hours and was unable to identify a well-defined center. The plane found multiple small and poorly-defined circulations embedded within a larger area of weak and variable winds, well to the south of the previous estimated center location. The plane also found that the minimum pressure has risen to around 1006 mb. All of this data confirmed what two late-arriving ASCAT overpasses from earlier this evening indicated, that Isaac has opened up into a southwest to northeast oriented trough. Since Isaac does not have a well-defined center, it no longer meets the NHC definition of a tropical cyclone and this is the last advisory. The strongest SFMR winds found by the plane were around 30 kt, mainly to the north of the deep convection, so the intensity has been set at that value. Although some of the regional hurricane models suggest that small short-lived circulations like the ones found by the plane could temporarily spin up within the larger envelope of the tropical wave over the next several days, none of the dynamical models currently show any significant redevelopment of Isaac. The wave will likely continue westward across the Caribbean Sea over the next few days, producing gusty winds and occasional heavy rains over portions of Hispaniola and Jamaica. This is the last public advisory issued by the National Hurricane Center on Isaac. Additional information can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and available online at https://ocean.weather.gov/shtml/NFDHSFAT1.shtml.
