000 WTPZ41 KNHC 242036 TCDEP1 Hurricane Fausto Discussion Number 24 NWS National Hurricane Center Miami FL EP062026 1100 AM HST Fri Jul 24 2026 The eyewall of Fausto has intermittently opened up this morning as intrusions of drier air disrupted the inner core convection. Recent satellite images depict a ragged, cloud-filled eye with prominent convective banding noted around the eastern and southern sides of the circulation. The initial intensity is held at 90 kt for this advisory, which is supported by a blend of the latest UW-CIMSS ADT/AiDT, D-PRINT, and SATCON estimates. The hurricane continues moving westward (275/13 kt) to the south of a narrow mid-level ridge that extends westward across the eastern and central Pacific. No major changes to the prevailing steering pattern are anticipated, so Fausto should continue on a westward to west-northwestward heading at a similar speed while it moves into the central Pacific basin and toward the Hawaiian Islands. The latest track guidance is slightly slower and a bit farther north at 72-120 h, and minor adjustments were made to the updated NHC track forecast at these times to account for the trends. Based on the environmental and oceanic conditions along the forecast track, and the latest intensity guidance, additional strengthening seems unlikely. As Fausto continues moving into a drier environment over slightly cooler waters, the models agree that the hurricane should gradually weaken during the next few days. After 72 h, increasing southwesterly shear is expected to increase the rate of weakening on Fausto's approach to Hawaii. In addition, the wind field is predicted to shrink and become more asymmetric on days 4-5, with the strongest winds confined to the northern portion of the circulation. No notable changes were made to the NHC intensity forecast this cycle, and Fausto is still predicted to be a tropical storm when it is in the vicinity of the Hawaiian Islands. Key Messages: 1. Although Fausto is expected to weaken as it approaches the Hawaiian Islands during the early to middle portions of next week, there is an increasing risk of some impacts from wind and rainfall. However, it is too soon to determine the exact location or magnitude of these impacts, and interests there should continue to monitor the progress of this storm.
