Hurricane Felicia Forecast Discussion Number 10

Issued at 800 AM PDT Fri Jul 16 2021 000 WTPZ41 KNHC 161452 CCA TCDEP1 Hurricane Felicia Discussion Number 10...Corrected NWS National Hurricane Center Miami FL EP062021 800 AM PDT Fri Jul 16 2021 Corrected 24-hour forecast position Compact Hurricane Felicia has continued to rapidly strengthen this morning with a well-defined, warm (>15C) clear eye now evident in infrared satellite imagery. However, the convective cloud tops surrounding the eye have warmed by almost 10 deg C during the past several hours, and a 1022Z ATMS microwave satellite pass showed the inner core convection a little less organized. Subjective satellite intensity estimates from TAFB and SAB were a consensus T6.0/115 kt and objective estimates from UW-CIMSS ADT over the past couple of hours have averaged T5.7/105 kt. The initial intensity is raised to 110 kt, and just below category 4 strength, for this advisory based on a blend of the various satellite intensity estimates and the slightly degraded aforementioned convective features. Felicia is moving west-southwestward or 255/07 kt. Strong deep-layer ridging to the north of the hurricane is expected to keep Felicia moving west-southwestward for the next 12-24 h. Thereafter, the global and regional models all show the ridge relaxing somewhat, which should allow Felicia to move more westward in the 24-120-hour forecast period. The new NHC track forecast is essentially on top of and just an update of the previous advisory track, and lies near the middle of the tightly packed simple and corrected consensus models TVCE, GFEX, and NOAA-HCCA. Some additional slight strengthening could occur this morning due to low vertical shear and warm SSTs conditions, with Felicia briefly becoming a category 4 hurricane. However, the warm water beneath the powerful hurricane isn't very deep as indicated by upper-ocean heat content values currently only around 5 units, which suggests that cold upwelling could begin at any time during the next 12 hours. Ocean heat content values are forecast to remain below 10 units from 24-96 hours, and decreasing to less than zero thereafter. Thus, slow weakening is forecast to begin by 24 h and continue through the remainder of the forecast period despite the favorable low (
