147 WTPA42 PHFO 012044 TCDCP2 Tropical Storm Nolo Discussion Number 45 NWS Central Pacific Hurricane Center Honolulu HI EP152026 Issued by NWS National Hurricane Center Miami FL 1100 AM HST Thu Oct 01 2026 Nolo is gradually becoming better organized. Moderate-to-deep convection has made a comeback near the center, with a large spiral band noted in the eastern semicircle. Additionally, microwave data indicate that the low-level core of the system remains fairly intact. The current intensity is held at 50 kt as the satellite estimates haven`t quite caught up with the earlier scatterometer pass. The storm continues to move slowly to the northwest. A subtropical high over the west-central Pacific is forecast to build north of the cyclone during the next few days. This evolution is expected to cause Nolo to turn westward by tomorrow and pick up a lot of forward speed over the weekend while moving generally west- northwestward, south of the main atolls of the northwestern Hawaiian Islands. Similar to the last advisory, the new forecast is nudged a bit the north to come into better agreement with the Google DeepMind and HCCA aids. After the recent failed extratropical transition, it will take a bit of time to re-build the warm-core structure aloft, so only a gradual strengthening is shown for the next 24 h. However, with convection near the center already, combined with the forecast drop in shear and increase in SSTs during the next 2-3 days, these factors suggest that a significant re-strengthening episode is coming. Since the low-level core structure is already present, rapid intensification is a distinct possibility by the weekend, and the new forecast is raised from the previous one, showing Nolo as a major hurricane when it crosses the International Dateline. Increasing shear could cause some weakening at the end of the forecast period.
