DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 100 PM CDT (1800 UTC), the center of Tropical Storm Cindy was located near latitude 27.7 North, longitude 92.9 West. Cindy is moving toward the northwest near 9 mph (14 km/h), and this motion is expected to continue today. A turn toward the north-northwest and then toward the north is expected tonight and Thursday. On the forecast track, the center of Cindy will approach the coast of southwest Louisiana and southeast Texas late today or tonight, and move inland over southeastern Texas or southwestern Louisiana on Thursday. Surface observations and reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is expected before landfall, with weakening expected thereafter. Tropical-storm-force winds extend outward up to 205 miles (335 km) mainly to the north and east of the center. The latest minimum central pressure reported by the Hurricane Hunter aircraft is 995 mb (29.38 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Cindy is expected to produce total rain accumulations of 6 to 9 inches with isolated maximum amounts of 12 inches over southeastern Louisiana, southern Mississippi, southern Alabama, and western portions of the Florida Panhandle through Thursday. This rainfall could cause life-threatening flash flooding in these areas. Rainfall amounts of 3 to 5 inches with isolated maximum amounts of 7 inches can be expected farther west across western Louisiana and eastern Texas through Thursday. Rainfall should spread northeastward across Arkansas and into portions of the Tennessee and Ohio Valleys through Friday, with total rain accumulations of 3 to 5 inches with locally higher amounts possible. WIND: Tropical storm conditions should spread westward and northward through the Tropical Storm Warning area today through Thursday. STORM SURGE: Inundation of 1 to 3 feet above ground level is expected along the coast in portions of the Tropical Storm Warning area. Inundation of 1 to 3 feet above ground level is also possible elsewhere along the coast from southeastern Louisiana to the western Florida Panhandle in areas of strong onshore winds.
