At 11am this Sunday morning, Tropical Storm Debbie is located 190 miles southeast of the mouth of the Mississippi River or 140 miles southwest of Apalachicola, Florida.
Maximum winds have increased to 60 mph with higher gusts. Some strengthening is expected over the next 48 hours.
Debby is moving slowly northeast at 6 mph and this motion will continue today. Debby is expected to gradually turn towards the northwest later tonight or Monday. On this track, Debby will move very slowly over the northern Gulf of Mexico over the next few days.
The forecast track has changed and now there appears to be a greater threat of landfall on the Louisiana coast late next week. The forecast also indicates Debby will be a very slow moving system over the next 5 days. This slow movement would cause an extended period of very heavy rainfall along the Gulf coast. Five day rainfall amounts could exceed 15 inches with widespread flood likely.
Tropical Storm Warnings have been posted for much of the Louisiana, Alabama, and Florida coasts. Tropical storm force winds of 39 mph and higher are expected to reach the coast later today and tonight.
