Relentless Storm System Drenches Texas with Torrential Rain, Flash Floods, and Dangerous Storm Potential from Dallas to the Hill Country

A Storm That Refuses to Move On

Texas entered another day under the weight of a slow-moving storm system that has already delivered impressive rainfall totals across the state. In Dallas, TX skies turned a muted gray before dawn, and rain dragged across the region in long, steady bands. A resident in Plano, TX described the scene early Thursday morning: “It felt endless. The water kept rising along the street."

A flash flood watch remains in effect for 12 million residents from north-central Texas down to Del Rio, TX along the Mexican border. Forecasters expect the watch to stay in place through Friday morning as the atmosphere funnels moisture into the region.

Heaviest Rain Concentrated South and West of San Antonio

Forecasters outlined the most intense rainfall west of San Antonio, TX through midday Thursday. Rates of 1 to 2 inches per hour are expected, with up to 4 inches possible within just three hours. Storm cells are crawling slowly, repeatedly dumping water over the same areas.

South-central Texas could see 1 to 3 inches of additional rain by Thursday night, with isolated totals reaching 6 to 8 inches. Communities north of Dallas have already collected more than 3 inches, with more storms on the way.

Meteorologists warned of a marginal risk for severe storms, including damaging winds, hail and an isolated tornado. The air remained warm and unstable, primed to release pockets of sudden rotation inside the broader storm field.

Flash Flood Emergency in the Texas Hill Country

Farther west, the Texas Hill Country endured the worst of the flooding. Since Thursday morning, more than 9 inches of rain fell across parts of western Hill Country, prompting officials to issue a flash flood emergency for nearly 1,300 people in southeastern Concho, western McCulloch and central Menard counties.

County judge Brandon Corbin announced precautionary evacuations for RV parks and campsites as creeks swelled into deep, churning flows. By Thursday evening the emergency was downgraded to a flood warning, but officials retained extra caution, noting that another inch of rain could fall overnight.

Storms lined up in a pattern known as “training," moving over the same areas repeatedly, similar to cars on a railroad track. The terrain amplified the danger. The Hill Country’s steep slopes and quick-responding creeks cannot handle hours of torrential rain without flooding.

Dallas-Fort Worth Area Hit with Rapid Flooding

Farther north, heavy rain triggered flash flood warnings across the Dallas-Fort Worth Metroplex. Roads in north Dallas were forced to close as runoff overtook traffic lanes and filled low points under overpasses. The National Weather Service reported 2 to 4 inches of rainfall early Thursday, with another 1 to 4 inches possible through the evening.

Flood watches stretched along the Interstate 35 corridor from Dallas-Fort Worth to Austin, TX, placing millions under heightened flood risk.

One resident in the Richardson, TX area described looking out at rising water along the curb. “The road disappeared under the runoff. You could see it flowing fast."

Another Round of Storms on the Way

Texas may get a brief chance to dry out Friday and Saturday, but forecasters warn that another soaking storm is set to arrive by late Sunday. The Weather Prediction Center has issued a Level 2 of 4 risk of flooding rainfall for northern and central Texas from Sunday into Monday.

Rainfall amounts this high are usually confined to the summer season. Meteorologists noted that ongoing unseasonable heat across the South has raised the atmosphere’s moisture capacity, allowing storms to wring out more intense rainfall.

Authorities urged residents in the Hill Country and across central Texas to keep phones charged, enable emergency alerts and avoid driving through flooded roads. “Turn around, do not drown," one official said as rain continued pushing across the hills.
