Hurricane Hector Forecast Discussion Number 22

2018-08-06 01:54:21| National Hurricane Center (East Pacific)

Issued at 500 PM PDT Sun Aug 05 2018 830 WTPZ45 KNHC 052354 TCDEP5 Hurricane Hector Special Discussion Number 22 NWS National Hurricane Center Miami FL EP102018 500 PM PDT Sun Aug 05 2018 This special advisory is to update the initial and forecast intensities for Hector. Satellite data indicate that the hurricane has continued to strengthen during the past 6 h, and the initial intensity has increased to at least 120 kt. Based on this, the intensities for the first 36 h of the forecast have been increased. There are no changes to the forecast track, the wind radii, or the intensities from 48-120 h. The NOAA G-IV aircraft is releasing dropsondes as it circumnavigates Hector during its flight to Hawaii to support forecast operations over the next few days. Data from these dropsondes should be incorporated into this evening's 0000 UTC dynamical models. While the official forecast track continues to lie south of the Hawaiian Islands, only a slight deviation to the north of the forecast track would significantly increase potential impacts on the Hawaiian Islands. It is a good time for everyone in the Hawaiian Islands to ensure they have their hurricane plan in place. For additional information on any potential local impacts from Hector in Hawaii, please refer to products issued by the NWS Weather Forecast Office in Honolulu at: http://www.prh.noaa.gov/hnl FORECAST POSITIONS AND MAX WINDS INIT 06/0000Z 14.5N 138.6W 120 KT 140 MPH 12H 06/0600Z 14.7N 139.8W 120 KT 140 MPH 24H 06/1800Z 15.3N 142.4W 115 KT 130 MPH 36H 07/0600Z 15.9N 145.3W 105 KT 120 MPH 48H 07/1800Z 16.4N 148.4W 95 KT 110 MPH 72H 08/1800Z 16.7N 154.5W 90 KT 105 MPH 96H 09/1800Z 17.0N 160.3W 85 KT 100 MPH 120H 10/1800Z 17.7N 166.0W 80 KT 90 MPH $$ Forecaster Beven
