UVALDE, Texas (AP) — Slow-moving storms with heavy rain were drenching a large swath of South Texas on Wednesday, spawning a tornado in San Antonio a day after downpours washed out roads and farmland and led to dozens of high-water rescues in the region.

The National Weather Service said a tornado touched down in the northwestern part of San Antonio near Interstate 10. Videos posted on social media showed what appeared to be a small twister. There were no immediate reports of injuries.

Warnings of potentially dangerous flash flooding, meanwhile, were posted in some areas as the deluge was expected to continue through Thursday evening. The weather service said 10 to 20 inches (25 to 50 centimeters) of rain was possible in some areas by the time the storms move out.

There have been no reports of deaths or injuries from the flooding.

Flash flood warnings were posted Wednesday morning for several counties near the Mexico border including parts of Kerr County, where catastrophic flooding along the Guadalupe River last year killed more than 100 people. Kerr County officials said they have been in contact with summer camps and retreat centers where river flooding could happen.

The highest rainfall totals so far have been in Uvalde County — up to 16 inches (40 centimeters) in some areas, the weather service said.

“This is called a typical mid-summer tropical weather pattern that happens in Texas,” said Monte Oaks, a meteorologist with the weather service. “About once every five years, we’ll get socked in with a daily recurrence of heavy rain chances that’s generally produced by a stagnant kind of a pattern with a low-pressure center that’s just not moving very fast.”

Oaks said the rain is being fueled with tropical moisture, mostly from the Gulf of Mexico and some from the Pacific Ocean.

The highest level of concern for potentially dangerous flooding Wednesday was for areas west of San Antonio and north of Route 90, he said.

Texas Gov. Greg Abbott issued disaster declarations for dozens of counties.

Authorities posted videos on Tuesday showing a rescue crew in a boat navigating flooded streets and a vehicle being swept away by fast-moving waters. Five people were rescued by the Texas Game Warden Search and Rescue Team and four were rescued by a local game warden, said Maggie Berger, a Texas Parks and Wildlife spokeswoman.

The weather service said the city of Uvalde has been hardest hit. Officials there said there had been at least two dozen water rescues, and a local event center was open for anyone displaced by flooding. In Sabinal, officials were also making plans for a shelter.
