Tropical Storm Norbert Forecast Discussion Number 23
2020-10-14 16:46:13| National Hurricane Center (East Pacific)
Issued at 900 AM MDT Wed Oct 14 2020 000 WTPZ44 KNHC 141446 TCDEP4 Tropical Storm Norbert Discussion Number 23 NWS National Hurricane Center Miami FL EP192020 900 AM MDT Wed Oct 14 2020 Recent satellite imagery suggests Norbert is beginning to feel the effects of deep-layer shear and drier mid-level air associated with a mid- to upper-level low pressure system centered to its west-northwest. While Norbert still shows signs of organization, the deepest convection is now displaced to the north of the estimated center position. The advisory intensity is held at 35 kt this morning based on objective and subjective current intensity Dvorak estimates from UW-CIMSS, SAB, and TAFB. It is likely that Norbert has peaked in terms of its intensity. Norbert's estimated initial motion is 325/13 kt. The cyclone is moving northwestward between a mid-level ridge over northern Mexico and the aforementioned mid- to upper-level low. This motion is expected to continue for the next 24 h, with a gradual decrease in forward speed as the upper low pulls away from Norbert. There is increasing spread noted in the model track guidance as the steering flow weakens between 24-48 h, but the general trend is for a slightly more northward motion during this time. Only minor adjustments were made to the official NHC track forecast, which remains close to the various consensus aids including TVCE and HCCA. Increasing deep-layer shear, drier mid-level air, and cooler sea-surface temperatures are expected to induce a weakening trend beginning later today, and Norbert will likely become a tropical depression this afternoon. The GFS simulated satellite imagery suggests Norbert will lose its deep convection within the next 24-36 h, and the official NHC forecast shows the system degenerating to a remnant low before dissipation at 48 h.

DISCUSSION AND OUTLOOK ---------------------- At 900 AM MDT (1500 UTC), the center of Tropical Storm Norbert was located near latitude 23.1 North, longitude 114.0 West. Norbert is moving toward the northwest near 15 mph (24 km/h). A northwestward motion with a gradual decrease in forward speed is expected through tonight, followed by a slower north-northwestward or northward motion on Thursday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Norbert is expected to begin weakening later today and become a remnant low late tonight or on Thursday. The remnant low is forecast to dissipate by Thursday night. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- None.
