305 WTPZ41 KNHC 210244 TCDEP1 Hurricane Fausto Discussion Number 9 NWS National Hurricane Center Miami FL EP062026 800 PM PDT Mon Jul 20 2026 Satellite imagery indicates that Fausto has continued to become better organized during the past several hours. Although some residual northerly shear remains evident, satellite imagery shows that the low- and mid-level circulations have become much better aligned than they were yesterday. Recent microwave and scatterometer data also support the improved structure, and the latest subjective Dvorak intensity estimate from TAFB indicate that Fausto has reached hurricane intensity. Based on these data and the improving satellite presentation, the initial intensity is increased to 65 kt, making Fausto the first hurricane of the 2026 eastern North Pacific hurricane season. The initial motion is estimated to be 315/8 kt. A slower northwestward motion is expected during the next day or two as the cyclone moves toward a weakness in the subtropical ridge. By Wednesday, high pressure is forecast to build north of Fausto, causing the cyclone to turn west-northwestward and gradually accelerate. Track guidance remains tightly clustered through about 72 h. Thereafter, a gradual increase in cross-track spread develops, with the GFS and the multi-model consensus (HCCA) on the right side of the guidance envelope and the ECMWF and GDMI on the left, or south, side. The updated NHC forecast is very close to the previous advisory and reflects a blend of the HCCA and the Google DeepMind ensemble mean. Fausto is expected to move into an environment of lower vertical wind shear while remaining over warm waters and within a moist air mass during the next couple of days. These conditions should support steady to rapid strengthening, although some lingering northwesterly shear could initially temper the rate of intensification. The NHC intensity forecast calls for Fausto to approach major hurricane intensity in about 48 h and remains near the middle of the guidance envelope through this time. A gradual weakening trend is expected thereafter as the cyclone moves over progressively cooler waters and into a drier, more stable environment.
