420 WTPA43 PHFO 120248 TCDCP3 Hurricane Henriette Discussion Number 32 NWS Central Pacific Hurricane Center Honolulu HI EP082025 Issued by NWS National Hurricane Center Miami FL 500 PM HST Mon Aug 11 2025 Satellite images show that the structure of Henriette has degraded a little over the past several hours. The eye feature seen earlier has disappeared, and the convective pattern has lost some organization. The initial intensity is nudged downward to 70 kt based on a blend of the latest satellite intensity estimates. An ASCAT pass shortly after 20Z confirmed that the wind field of Henriette is very compact, with its tropical-storm-force winds extending no more than 60 n mi from the center. Henriette is likely to maintain its intensity through tonight, but weakening should commence shortly thereafter. In fact, the weakening trend on Tuesday and Wednesday is likely to be quite fast as the small system will be moving over sharply cooler waters and into an environment of strong shear. Most of the models show Henriette becoming a post-tropical cyclone in 48 to 60 hours and dissipating entirely in about 4 days, and that is reflected in the official forecast. The hurricane is moving northwestward at about 15 kt. This general motion is expected to persist during the next couple of days as the cyclone continues to be steered by the flow between a mid-level ridge to its northeast and a mid- to upper-level low currently situated northwest of Henriette. After that time, a turn to the north-northwest is expected in the low-level flow. The models are in good agreement, and little change was made to the previous track.
