Map of flood hazard areas in Texas

There is currently a flood risk in South Texas. The National Weather Service (NWS) issued warnings for heavy rainfall in the south-central part of the state, which could result in flash flood waters.

The heavy rainfall will produce "numerous areas where flash flooding events are possible," the NWS warned in its Thursday forecast. "Many streams may flood, potentially affecting larger rivers."

Some of the cities affected will include Fredericksburg, Burnet, San Antonio, Boerne, San Marcos, Leakey, Rocksprings, Blanco, Uvalde, Llano, Del Rio, New Braunfels, Kerrville, Hondo, Brackettville, Georgetown, Austin, Bandera and Eagle Pass.

Kerr County is in the areas that will be impacted. In July, historic floods left the area with more than a hundred dead.

The warnings will remain in effect until 6 AM Friday.

Austin/San Antonio forecast

The NWS of Austin/San Antonio warned of rainfall between 1 and 3 inches (2 and 7.6 cm), with isolated totals of up to 8 inches (20 cm) in the western Hill Country and southern Edwards Plateau.

"Excessive runoff from this heavy rainfall will likely lead to flooding of rivers, creeks, streams, and other low-lying, flood-prone locations," it said. "Stay weather aware and keep checking for weather updates from us and trusted sources."

It further detailed that multiple storms will pass slowly, one after another, accompanied by heavy rain, across the southern Edwards Plateau and western Hill Country region. 

The heaviest precipitation will occur west of I-35 through Friday. They also recommended turning your car around when faced with flooded roads: "Never drive through flooded roads."

Fort Worth/Dallas forecast

"As one wave of heavy precipitation shifts east, another round of storms will arrive later today," the weather service's Fort Worth/Dallas office maintained. The first rains were recorded during the morning.

"The main area of concern is now under a Flood Watch through midnight," it also forecast. "In addition to the flooding threat, there is a threat for a brief spin-up across Central Texas in the afternoon."

While 1 to 2 inches (2.54 to 5 cm) of rainfall is expected in most of the affected areas, some areas could see up to 4 inches (10 cm).

After an improvement at the end of the week, the precipitation forecast worsens again for the weekend. Sunday will have a 60%-80% chance of rain. However, for Thanksgiving an improvement is expected.

Texas Gov. elevates risk level

Gov. Greg Abbott on Wednesday urged state agencies to prepare for the arrival of rain this Thursday.

"Texans are urged to remain weather-aware and heed the guidance of state and local officials and emergency response personnel to protect themselves and their loved ones."

The Texas Division of Emergency Management (TDEM) announced the deployment of more than 200 rescuers and more than 100 pieces of equipment across the state in response to the governor's request to raise the level of preparedness:
