DISCUSSION AND OUTLOOK ---------------------- At 1100 PM HST (0900 UTC), the center of Tropical Storm Norbert was located near latitude 16.6 North, longitude 123.3 West. Norbert is moving toward the west near 15 mph (24 km/h) and this general motion is expected to continue over the next few days. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some strengthening is forecast, and Norbert could become a hurricane this weekend. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 996 mb (29.42 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 AM HST.

TROPICAL STORM NORBERT DISCUSSION
Expires:No;;263491 WTPZ44 KNHC 110857 TCDEP4 Tropical Storm Norbert Discussion Number 7 NWS National Hurricane Center Miami FL EP142026 1100 PM HST Thu Sep 10 2026 Convection has increased and become more organized around Norbert tonight, with cloud-top temperatures below -80 C observed within the CDO. However, the tropical storm continues to contend with moderate westerly wind shear, with the center of the low-level circulation located near the western edge of the deep convection. Subjective and objective Dvorak intensity estimates have increased this evening, ranging from 45 to 59 kt. Given the improving convective organization and the higher intensity estimates, the initial intensity is set at 50 kt for this advisory. Norbert is moving westward around 13 kt along the southwestern periphery of a mid-level ridge building over the eastern Pacific. This general motion with a slightly slower forward speed is expected over the next few days as the ridge strengthens and builds westward. The forecast becomes more complex by the end of the weekend and into next week, as the strength and position of the ridge will likely determine Norbert’s longer-term track. A stronger ridge would favor a west-southwestward to southwestward motion, while a weaker ridge would allow Norbert to continue moving westward for a longer period. The latest NHC forecast calls for Norbert to turn toward the west-southwest by early next week and is similar to the previous track forecast. Decreasing wind shear and sufficiently warm sea surface temperatures should support gradual strengthening over the next few days, although some mid-level dry air immediately west of the cyclone could limit the extent of the intensification. Beyond 72 h, a wide spread develops in the intensity guidance, in part because the eventual track will influence Norbert’s intensity. A farther south track would allow for Norbert to stay over slightly warmer waters, supporting a stronger system. The latest NHC intensity forecast has been raised slightly from the previous advisory through the next day or so and lies near the upper end of the intensity guidance, close to the HCCA and Google DeepMind solutions. Given the large model spread, forecast confidence is slightly below normal beyond 72 h.
