Record-setting rains left officials in Texas and Oklahoma scrambling to assess the scope of the damage and destruction Monday as an emergency coordinator told reporters that a dozen people were missing in one county.
The 12 people missing in Hays County, Texas, come from families who had gathered for the long weekend, said Ken Bell, emergency coordinator for San Marcos, one of the cities hardest hit by the storms and flooding.
The group likely includes children, Bell said.
A day after severe weather left three people dead and washed away hundreds of homes in Texas and Oklahoma, the storms are easing up.
But it doesn’t mean the threat is gone.
The torrents that those storms dumped are still too much for river and creek banks to contain, and runoff was peaking early Monday, threatening continued flooding, the National Weather Service warned.
And rain relief is not coming to everyone. Forecasters warned that with the ground already saturated, even a small amount of new rain could have devastating consequences.
“Only an inch or two of rainfall could quickly lead to more flash flooding concerns,” the weather service said.
The destruction and threat of more inclement weather prompted Texas Gov. Greg Abbott to add 24 counties to the 13 already under an emergency disaster declaration, allowing the state to use all the resources “reasonably necessary to cope with this disaster.”
Forecasts call for thunderstorms, hail, high winds, flash flooding, river flooding and tornadoes this week, the governor’s statement said.
Texas homes wiped away
In Hays County near Austin, up to 400 homes have washed away. “We do have whole streets that have maybe one or two houses left on them, and the rest are just slabs,” said Kharley Smith, emergency management coordinator.
More than 1,000 more homes were damaged, and waters washed two main bridges away in Hays.
Thunderstorms could dump 1 to 3 more inches of rain there Monday — 5 inches in isolated areas, the weather service said.
While flood warnings and watches were winding down in most places overnight, a new flood watch loomed from Monday into early Tuesday for Hays County.
One person was confirmed dead in San Marcos, and bad weather hindered the search for missing people Sunday. Rescuers used helicopters to heave stranded residents off the rooftops of buildings surrounded by flood lakes, where normally fields stand.
The Blanco River, which flows through San Marcos, shot past its previous flood record of 33.3 feet to 40.21 feet late Saturday.
Hours earlier, it ran just over 5 feet deep, according to weather service data. Fortunately, its floodwaters should make a rapid retreat.
Nearly 200 miles northeast of Hays County, near Houston, an area of about 400 homes around Louis Creek Dam is under mandatory evacuation. The dam has not breached, but workers continue to pack soil on it.
Oklahoma firefighter drowned
In neighboring Oklahoma, two people died.
On Saturday, a woman in Tulsa died after her car hydroplaned. In the nearby town of Claremore, a firefighter got swept into a storm drain while attempting a high-water rescue Sunday.
There, water levels in creeks usually waste-deep raged up two dozen feet or more over the weekend. Markers signifying moderate to major river flooding dotted the weather map, particularly along the border with Texas.
The weekend deluges caused Oklahoma City to break its all-time rainfall record for any single month. But much of Oklahoma got a rain break Sunday. Fog wafted through Tulsa, and on Monday, there was a chance of thunderstorms there.
A flood watch is on from the southern Plains to the Gulf of Mexico. The heavier rains are moving east, where they are sending some rivers and creeks over their banks.
