At 100 PM CDT (1800 UTC), the center of Tropical Storm Cindy was centered near latitude 25.9 North, longitude 90.5 West. Cindy has been stationary for the past few hours, but the system is expected to resume a motion toward the northwest at around 10 mph (17 km/h) later today, and this motion is expected to continue through Wednesday night. A turn toward the north-northwest is forecast early Thursday. On the forecast track, Cindy is expected to approach the coast of southwest Louisiana late Wednesday or Wednesday night, and move inland over western Louisiana and eastern Texas on Thursday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast before the system reaches the coast on Thursday. Tropical-storm-force winds extend outward up to 205 miles (335 km), mainly to the north and east of the center. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the coast within the warning area later today and spread westward within the warning area through Wednesday.
