| #1060807 (Received by flhurricane at: 10:50 PM 08.Sep.2021) TCDAT3 Tropical Storm Mindy Discussion Number 2 NWS National Hurricane Center Miami FL AL132021 1100 PM EDT Wed Sep 08 2021 Doppler radar data and surface observations indicate that the center of Mindy made landfall over St. Vincent Island, Florida, near 0115 UTC. Since that time, the center has been moving along the shoreline of Apalachee Bay. The intensity is held at 40 kt based on continuity from earlier buoy data and a 43-kt wind at an elevated tower south of Apalachicola. The central pressure has been lowered to 1002 mb based on surface obs from the Apalachicola area. It should be noted that while Mindy is not well organized in satellite imagery, but it has a good radar presentation. The initial motion is 055/17. A general east-northeastward motion should continue for the next 24 h or so as Mindy moves along the southern edge of a deep-layer mid-latitude trough moving across the eastern United States. After that, a decrease in forward speed and a more eastward motion are expected as the aforementioned trough moves away from Mindy and the cyclone becomes vertically shallow. The forecast track keeps the center along the Gulf coast for a few more hours, followed by a motion across northern Florida and southeastern Georgia into the Atlantic. The new forecast track is a little faster than the previous forecast. Little change in strength is likely during the next few hours while the center of Mindy straddles the coast. Weakening should occur as the center moves farther inland later tonight, aided by an increase in westerly vertical wind shear. By the time the cyclone reaches the Atlantic, the shear should be strong enough to make the system continue to weaken. The new intensity forecast is a little stronger than the previous forecast during the first 12 h, then is similar to the previous forecast in calling for the cyclone to dissipate after 72 h. Key Messages: 1. Tropical Storm Mindy is expected to produce heavy rainfall from the Florida Panhandle into southern portions of Georgia and South Carolina through Thursday morning. This rainfall may produce isolated to scattered flash, urban, and small stream flooding. 2. Tropical storm conditions are expected through tonight in portions of the Florida Panhandle where a Tropical Storm Warning is in effect. Tropical storm conditions are also possible across portions of the northern Florida Peninsula and southeastern Georgia near the center of Mindy.
