Tropical Storm Hanna is located 115 miles east-southeast of Corpus Christie, Texas, and is moving to the west at 9 mph (15 km/h).

NHC forecasters say that a gradual turn toward the west-southwest is expected by tonight and that motion should continue through Sunday.

On the NHC forecast track, the storm center should make landfall along the Texas coast within the warning area this afternoon or early evening.

Spaghetti models are in good agreement that the tropical cyclone will continue on a westerly track followed by a turn to the west-southwest.

The new NHC forecast track has been adjusted just a bit to the south of the previous forecast. This is just north of the dynamical model consensus and just south of the latest ECMWF track.

Tropical Storm Hanna has maximum sustained winds of near 70 mph (110 km/h), with higher gusts.

Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center of the tropical cyclone.

Additional strengthening is forecast, and Hanna is expected to become a hurricane today before the cyclone makes landfall. Rapid weakening is expected after Hanna moves inland.
