Tropical Storm Alberto approaches landfall in Mexico as Texas threatened by flooding, tornadoes

Tropical Storm Alberto is then expected to begin to weaken rapidly once it moves onshore and will likely dissipate over Mexico later Thursday or Thursday night.

As of Thursday at 8 a.m. ET, Tropical Storm Alberto made landfall in northeastern Mexico. Continuous coverage of Tropical Storm Alberto has moved here.

Tropical Storm Alberto became the first named storm of the 2024 Atlantic hurricane season Wednesday, and as the system churned over the open waters of the Gulf of Mexico, it blasted parts of Texas, Louisiana and Mexico with heavy rainfall, storm surge flooding and gusty winds.

At last report from the National Hurricane Center (NHC), Alberto was a minimal tropical storm with winds mainly around 50 mph. However, its influence stretched hundreds of miles.

Despite the center of circulation being more than 200 miles south of the Rio Grande, widespread coastal flooding was reported along barrier islands and coastal communities from Brownsville, Texas, to Grand Isle, Louisiana.

The FOX Forecast Center said due to the system's lack of organization and a steep pressure gradient, coastal flooding was more significant than what is normally experienced during a low-end tropical storm.

Seas as high as 16 feet were reported in the Gulf of Mexico on Wednesday afternoon, which helped cause water level rises of 3-5 feet along the Texas coastline.

Major flooding was reported in Surfside Beach and the San Louis Pass region, which are south of Galveston.

Photos and video from coastal communities showed streets that were inundated by seawater, especially during high tide.

In addition to the coastal flooding, some communities were also placed under Tornado Warnings as the initial bands of rainfall interacted with the land.

There were reports of significant roof damage near Rockport, Texas, on Wednesday evening from a suspected tornado.

Texas Governor Greg Abbott issued a severe weather disaster declaration for 51 counties throughout the state due to the potential of inland and coastal flooding.

As of Thursday morning, the Tropical Storm Warning that had been in effect along the Texas coastline has been discontinued.

Tropical Storm Warnings remain in effect for the northeastern coast of Mexico south of the mouth of the Rio Grande River to Tecolutla.

HOW TO PREPARE FOR HURRICANE SEASON

The rainfall associated with Tropical Storm Alberto is expected to start diminishing across South Texas during the day on Thursday, with only about 1 inch of additional rain expected.

A few brief tornadoes are also possible in South Texas on Thursday morning as Alberto moves inland over northeastern Mexico.

The heavy rainfall will continue to impact Mexico throughout the day. Rainfall totals there could range from 5-10 inches, with locally higher amounts of up to 20 inches possible across the higher terrain.

"This rainfall will likely produce considerable flash and urban flooding along with new and renewed river flooding," the NHC said. 

In addition, mudslides are possible in the higher terrain of northeastern Mexico.
