Maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. The system should continue to weaken, and dissipate later this week. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the Central Pacific Hurricane Center on this system.

Post-Tropical Cyclone HENRIETTE Forecast Discussion
454 WTPA43 PHFO 130847 TCDCP3 Post-Tropical Cyclone Henriette Discussion Number 37 NWS Central Pacific Hurricane Center Honolulu HI EP082025 Issued by NWS National Hurricane Center Miami FL 1100 PM HST Tue Aug 12 2025 Henriette has failed to produce any deep convection near the low-level center for about 12 hours. Global models show that convection is not expected to return over the low-level center in an environment of strong vertical wind shear, dry mid-level air, and cooling SSTs along the forecast track. With convection not anticipated to return, Henriette is now designated as a post-tropical cyclone. A recent scatterometer Metop-B pass at 0717 UTC showed winds around 35-39 kt, mainly in the eastern semi-circle. Using this data, and an assumed weakening trend from the previous advisory the intensity is set to 40 kt. The cyclone is moving towards the northwest at 325/17 kt. This general motion should continue through Wednesday, with a turn to the north, then northeast around a large subtropical ridge as the system continues to weaken. The cyclone is forecast to open into a trough and dissipate by the end of the week. This is the last advisory for this system.
