CHANGES WITH THIS ADVISORY: The Tropical Storm Warning along the Gulf coast of Florida has been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests along the Atlantic coast of northeastern Florida and southeastern Georgia should monitor the progress of Mindy. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.

RAINFALL: Mindy is expected to produce storm total rainfall of 2 to 4 inches with isolated maximum amounts of 6 inches across portions of southern Georgia and coastal South Carolina through this morning. This rainfall may produce isolated to scattered flash, urban, and small stream flooding.

WIND: Tropical storm force wind gusts may occur near the center of Mindy over portions of the southeastern Georgia through this morning.

TORNADOES: A tornado or two is possible over portions of north Florida and far south Georgia through this morning.

At 500 AM EDT (0900 UTC), the center of Tropical Depression Mindy was located near latitude 30.8 North, longitude 83.0 West. The depression is moving toward the northeast near 20 mph (31 km/h), and this general motion is expected to continue today. A slower east northeastward motion is forecast tonight through Saturday. On the forecast track, the center of Mindy is expected to move across southeastern Georgia this morning, and over the western Atlantic by late this morning or early this afternoon.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Little change in strength is forecast through tonight. Gradual weakening is expected on Friday, and Mindy is forecast to become a remnant low by Saturday. The minimum central pressure estimated from surface observations is 1004 mb (29.65 inches).

Doppler radar data and surface observations show that the center of Mindy has moved inland over southern Georgia overnight. Now that more of the circulation has moved over land, the cyclone has weakened and the latest observations indicate that Mindy has become a tropical depression with an estimated intensity of 30 kt. Mindy is forecast to move over the western Atlantic by this afternoon, but strong southwesterly shear is expected to prevent re-strengthening. In fact, the shear is forecast to increase to around 35 kt by tonight, and this is likely to strip away any remaining deep convection and cause gradual weakening. Mindy is forecast to become a remnant low in about 48 hours and dissipate by day 3, but given the expected shear both of those events could occur sooner.

Mindy continues to move briskly northeastward or 055/17 kt. There has been no change to the track forecast philosophy since the previous advisory. Mindy should continue to move northeastward near the southern portion of a deep-layer trough that will be moving across the eastern United States today. Once the trough begins to lift northeastward late tonight and Friday, Mindy should slow down and turn east-northeastward until dissipation occurs. The guidance envelope has shifted slightly northward this cycle, and the updated NHC track forecast has been modified accordingly. The new NHC track lies between the GFEX consensus aid and the GFS ensemble mean.

Doppler radar data and surface observations show that the center of Mindy has recently moved offshore the coast of Georgia. Buoy 41008 located off the Georgia coast recently recorded 1-min sustained winds of 29 kt with gusts as high as 33 kt. Thus, 30 kt is maintained as the intensity for this advisory.

Mindy is located in an environment of strong south to southwesterly vertical wind shear. Over the next 24 h, the shear is expected to become even stronger. The strong shear should prevent restrengthening and is likely to strip away any remaining convection by Friday or Friday night. Mindy is forecast to become post-tropical Friday evening. Most of the global models suggest that the cyclone will open up into a trough in 36-48 h, but it is possible this could happen sooner, as surface observations already show that easterly winds on the north side have become quite weak. The NHC forecast calls for dissipation Friday night, which is sooner than the previous advisory.

Mindy continues moving quickly to the east-northeast or 065/18 kt. There has been no change to the track forecast philosophy. Mindy is forecast to continue moving east-northeastward at a similar speed for the next 24 h near the southern portion of a deep-layer trough moving across the eastern United States. Once the trough begins to lift northeastward, Mindy should slow down a little on Friday. The main adjustment to the NHC track is to show a slightly faster motion toward the east-northeast at the 24-36 h points.
