Update: Tropical Storm Hanna Headed Toward South Texas

July 24, 2020

A storm churning in the Gulf of Mexico that yesterday was a tropical depression is now Tropical Storm Hanna, the National Hurricane Center has reported.

TS Hanna’s center is currently located south of the Texas/Louisiana border and is moving in a west-northwest direction at around 9mph. The NHC said, however, that Hanna is expected to turn to a more westerly direction. A tropical storm warning is now in effect from the mouth of the Rio Grande to San Luis Pass, Texas, meaning tropical storm conditions may be expected within the warning area in the next 24 to 36 hours.

Hanna is expected to turn toward the west tonight and shift to a westward to west-southwestward motion through the weekend. The NHC said the storm would likely make landfall along the Texas coast on Saturday afternoon or evening.

Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Gradual strengthening is expected until the tropical cyclone makes landfall. Steady weakening is expected after Hanna moves inland.

Tropical storm force winds extend outward up to 60 miles (95 km) from the center.

Hanna is expected to produce 4 to 8 inches of rain with isolated maximum totals of 12 inches through Sunday night in south Texas. The upper Texas and Louisiana coasts and expect 3 to 5 inches of rain from the tropical storm.

Swells generated by Hanna are expected to increase and affect much of the Texas and Louisiana coasts during the next few days.
