000 WTPZ44 KNHC 110239 TCDEP4 Tropical Storm Norbert Discussion Number 6 NWS National Hurricane Center Miami FL EP142026 500 PM HST Thu Sep 10 2026 Norbert continues to show a shear pattern on satellite imagery, with the center located on the western edge of a strong and growing area of convection. Objective satellite estimates are higher than the last advisory, so the initial intensity is nudged upward to 45 kt. Only slow strengthening is anticipated for the next few days while Norbert experiences light-to-moderate westerly shear over warm waters, though close to some dry mid-level air. Thus, Norbert will likely have some challenges developing an inner core, probably preventing any rapid changes in the near-term. Model guidance is higher than the last cycle overall, and the new intensity forecast is raised slightly from the previous one. The long-range intensity is a challenge given the large latitudinal spread in the track guidance as well as the possibility of increasing shear. The tropical storm's motion remains westward at 12 kt. A mid- level ridge over the eastern Pacific is forecast to build westward in tandem with Norbert during the next few days, keeping the cyclone moving westward to west-northwestward. A south-of-west track is possible by next week, depending on the future orientation of the ridge and the position of Norbert. The ECMWF has been showing this west-southwest motion for a few runs now, and with the Google DeepMind now in closer agreement, the official forecast is shifted southward at long range. Otherwise few changes were made to the previous forecast.
