At least eight people are dead and several others are missing in Travis, Williamson and Burnet counties after flash floods swept through the area Saturday.

The National Weather Service has issued a flash flood warning for the area northwest of Austin until 6:30 p.m. Sunday. That includes the cities of Cedar Park, Lago Vista, Hudson Bend, Leander, Georgetown and Liberty Hill.

People in the area should move immediately to higher ground and avoid walking or driving through floodwaters. The NWS recommended people have multiple ways to receive weather-related warnings.

A flood watch for the region is in effect through 7 p.m.

Emergency service departments said search efforts for missing people are still underway, including searches along Sandy Creek and Cow Creek. There are also dozens of road closures across Northwest Austin, Georgetown, Cedar Park and Marble Falls.

Here’s the latest from nearby counties affected by the flooding.

Travis County

Four people died during flash floods in Travis County, County Judge Andy Brown said at a news conference Sunday. Several others were missing, though he could not confirm an exact number.

Austin-Travis County EMS said personnel had rescued 25 people in the northwest area of the county.

Sheriff Sally Hernandez said flood-related calls to 911 had gone from 49 at 1 a.m. Saturday to 112 by 3 a.m.

“As daylight came and devastation became very painfully evident, we continued rescue efforts,” she said at the news conference, “and our special response team went door to door, checking on the welfare of all of those 911 callers that called in during the overnight hours.”

Brown and local emergency management officials said they believed NWS had been proactive in sending out alerts and warnings before and during the floods. Travis County Chief Emergency Management Coordinator Eric Carter said it was too soon to say whether any of the deaths associated with the flooding could have been prevented.

County officials said people affected by the floods who have immediate needs for shelter, clothing, food or water should call the Red Cross at 1-800-733-2767. Property damages can be reported to the Texas Department of Emergency Management.

Brown said people should refrain from any recreational water activities on local lakes over the coming days as emergency crews continue their recovery efforts and clear debris.

Separately, Austin ISD Superintendent Matias Segura said in an email to the community Saturday that families in the district had been impacted by the floods in Kerr County.

Williamson County

In Williamson County, one person was confirmed dead from the flooding and two others are missing.

At a news conference Sunday, Sheriff Matthew Lindeman said calls started coming in before 2 a.m. Saturday about water rising over roadways in the Liberty Hill area. After 5 a.m., calls came in from far western Williamson County about floodwater going into homes.

Lindeman said two people were in a vehicle on FM 1869, west of Liberty Hill, when it was driven into high water and stalled just before 7 a.m. One person was able to escape, he said, but the other person was swept away and has not been found.

After sunrise Saturday, deputies went door to door in RV parks in a low-lying area along Highway 29 east of Georgetown, telling people to move to higher ground. Most heeded the warning.

“However, one was rescued a little later in the day by swift-water rescue teams from Parks & Wildlife and the sheriff’s office,” the sheriff said. “A number of pets were rescued as well.”

By the afternoon, the Sheriff’s Office got a call about a vehicle being swept away from County Road 284, west of Liberty Hill. The vehicle was found hours later, still partially submerged with no one seen inside. Lindeman said it was not until after the water had begun to recede late Saturday that a body was found near that vehicle.

Searches continued on the ground and from the air on Sunday for the two people listed as missing.

A boil water notice for parts of Georgetown was issued Saturday afternoon due to a line break likely related to the floods.

Burnet County

In Burnet County, there are three confirmed deaths and five people reported missing. County officials said there have been 93 rescues, primarily in the areas around Cow Creek and Hamilton Creek.

“We’ve had [people] in cars with water, we’ve had them on top of cars, we’ve had them in trees, we’ve had them in homes that were surrounded by water, we’ve had them on rooftops,” Capt. Mike Sorenson with the Burnet County Sheriff’s Office said.

The Sheriff’s Office has been working with several local, state and federal agencies on rescue efforts. Major General Thomas M. Suelzer with the Texas National Guard said emergency personnel are working in Burnet County, where there have been five air evacuations.

Now, Sorenson said, crews are shifting gears from rescuing to recovering.

“We may never find some of these folks, unfortunately,” he said, “but we’re still looking.”

The Sheriff’s Office has a list of road closures and areas they recommend people avoid on its Facebook page.

The department is experiencing issues with its phone lines. Officials said people should call 911 for emergencies.
