| #1151992 (Received by flhurricane at: 4:47 AM 09.Sep.2023) TCDAT4 Tropical Storm Margot Discussion Number 8 NWS National Hurricane Center Miami FL AL142023 500 AM AST Sat Sep 09 2023 Margot has become better organized this morning. The earlier noted exposed surface center has become obscured with bursts of deep convection while the outflow pattern has become more diffluent in the northeast quadrant of the cyclone. Therefore, the initial intensity is raised to 40 kt and is based on the TAFB and SAB Dvorak satellite intensity estimates. Although some northerly shear and dry mid-level air intruding from the southwest has slowed the intensification rate, the intensity guidance indicates that Margot will become a hurricane next week. In fact, the upper-level pattern becomes more favorable by mid-period, although the statistical SHIPS intensity guidance shows modest southerly shear at the time. Therefore, the official forecast indicates gradual intensification through the entire forecast period. The NHC intensity forecast favors the reliable multi-model consensus aids, which is just below the Decay SHIPS beyond day 3. Margot is moving west-northwestward at 11 kt around the southwestern periphery of a subtropical high over the eastern Atlantic. A west-northwest to northwest motion is forecast through early Sunday, followed by a turn toward north-northwest to north by late Sunday with some reduction in forward speed. A slight adjustment to the right of the previous forecast track was made to hedge closer to the HFIP HCCA corrected consensus aid and TVCA simple multi-model guidance.
