DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Paulette was located near latitude 18.4 North, longitude 43.3 West. Paulette is moving toward the northwest near 6 mph (9 km/h). A turn toward the west-northwest or west with a slight increase in forward speed is expected during the next couple of days. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Moderate additional strengthening is possible today and Paulette could be near hurricane strength by tonight. Gradual weakening is expected by late Wednesday. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 995 mb (29.39 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Zelinsky

Tropical Storm Paulette Forecast Discussion Number 6

Issued at 500 AM AST Tue Sep 08 2020 000 WTNT42 KNHC 080835 TCDAT2 Tropical Storm Paulette Discussion Number 6 NWS National Hurricane Center Miami FL AL172020 500 AM AST Tue Sep 08 2020 GOES-16 Proxy-VIS and enhanced BD-curve infrared imagery reveals that Paulette's cloud pattern has continued to improve during the past several hours. Specifically, the developing inner core is much more symmetric with new bursts of deep convection (-76C cloud tops) near the surface circulation center. Subsequently, subjective and objective satellite intensity estimates support an initial intensity of 45 kt. The global models and the statistical-dynamical intensity guidance indicate increasing southwesterly shear commencing later today. So, only modest strengthening is shown in the NHC foreast during next 24 hours. On Friday, the shear stiffens and becomes less diffluent as the cyclone approaches the high amplitude mid-Atlantic TUTT. Therefore, Gradual weakening is expected to occur at that time. Beyond day 3, there are some mixed signals, specifically in the GFS/FV3 and ECMWF SHIPS output. The GFS/FV3 continues to indicate strong southwesterly shear through day 5 further weakening Paulette to a depression around day 4. The ECMWF SHIPS, however, shows a more southerly and diffluent upper wind pattern supporting reintensification after day 4. The intensity forecast sides with that latter solution and also agrees with the HCCA intensity multi-model indicating the same intensity trend. The initial motion is estimated to be northwestward, or 325/5 kt. The rather weak synoptic steering pattern consists of a large mid- to upper-level low just west of the Canary Islands and ridging to the northwest of the cyclone. During the next couple of days, the large-scale models show the upper low filling and lifting northeastward, allowing the subtropical ridge to build in behind the departing upper low from the western Atlantic. This change in the pattern should cause Paulette to turn west-northwestward on Wednesday and continue moving in this general motion through early Saturday. Through the remaining portion of the period, the global models indicate a major shortwave trough moving off of the northeast coast of the U.S. and breaking down the western extent of the subtropical ridge/Bermuda high. This growing weakness in the ridge should cause Paulette to turn toward the northwest early Sunday. The official track forecast is a little bit slower and to the right of the previous forecast after day 3, and is close to the various consensus aids.
