Tropical Storm Hanna expected to strengthen

24 Jul 2020 / Texas & Louisiana, United States

At 400 AM CDT (0900 UTC), Tropical Storm Hanna was near latitude 26.7 North, longitude 92.4 West. Hanna is moving toward the west-northwest near 9 mph (15 km/h) and a turn toward the west is expected tonight, followed by a generally westward motion through the weekend. On the forecast track, the storm center should make landfall along the Texas coast within the warning area on Saturday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Strengthening is expected until the system makes landfall. Steady weakening is expected after Hanna moves inland…

WIND: Tropical storm conditions are expected in the warning area by tonight or Saturday morning. Tropical storm conditions are possible within the watch area by tonight or Saturday morning.

RAINFALL: Hanna is expected to produce 4 to 8 inches of rain with isolated maximum totals of 12 inches through Sunday night in south Texas. This rain may result in life-threatening flash flooding, rapid rises on small streams, and isolated minor to moderate river flooding in south Texas. 3 to 5 inches of rain is expected along the upper Texas and Louisiana coasts, and inland to the Mexican states of Coahuila, Nuevo Leon, and northern Tamaulipas.

SURF: Swells generated by Hanna are expected to increase and affect much of the Texas and Louisiana coasts during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
