000 WTPZ42 KNHC 250834 TCDEP2 Tropical Storm Genevieve Discussion Number 4 NWS National Hurricane Center Miami FL EP072026 300 AM CST Sat Jul 25 2026 Microwave and scatterometer data received since the previous advisory indicates that Genevieve has a small inner wind core, with conventional imagery showing strong convection near and just south of the center. However, it is unclear whether a tight convective spiral seen in the microwave data has continued to develop since the overpass. Satellite intensity estimates are generally near 45 kt, so that will be the initial intensity. The initial 34-kt wind radii have been decreased a little based on the scatterometer data. The track forecast reasoning is unchanged since the previous advisory. A strong mid-level anticyclone system is centered over the western United States, with a ridge axis extending west- southwestward over the Pacific Ocean. This will be the main driver of Genevieve's motion over the next 5 days and should keep the storm away from the coast of Mexico. The track guidance remains in good agreement that the cyclone will move west-northwestward or northwestward during the forecast period with some ups and downs in forward speed. The new forecast track is almost identical to the previous forecast and lies near both HCCA and the Google DeepMind Ensemble Mean. The cyclone is forecast to be in an environment favorable for steady to rapid strengthening, especially given the presence of the small inner core. While there could be a little northerly shear, the rapid intensification indices of the SHIPS model are very high, with a 75-90 percent chance of 55 kt of strengthening during the next 48 h. The main issue remains just how strong Genevieve will get. The HCCA model continues to show a peak intensity near 130 kt, while most of the other guidance is clustered between peak intensities of 100-115 kt. The new intensity forecast will keep the 115 kt peak intensity from the previous forecast, which is at the upper edge of everything but HCCA. After reaching peak intensity in about 60 h, Genevieve is expected to encounter a drier air mass and eventually cooler waters. This combination should cause slow to steady weakening.
