PASADENA, Texas (AP) — A powerful storm system took aim at the Gulf Coast on Tuesday, spawning a tornado that caused damage east of Houston.

The National Weather Service had issued a tornado emergency for that area, warning that a “large, extremely dangerous and potentially deadly tornado” was on the ground Tuesday afternoon and was headed toward Baytown, about 25 miles (40 kilometers) east of Houston. The warning expired as the system moved to the east.

There were downed power lines and damage to homes and businesses in Baytown, but no reports of serious injuries, said Baytown spokesperson Jason Calder.

Footage from Houston TV station KTRK showed damage to buildings and power lines in Pasadena, a city southeast of Houston, including doors knocked off a Harley-Davidson dealership. Several businesses suffered major damage, including the city’s animal shelter. Nearby, fences were laid over and shingles and sections of roofs were torn from homes, but there were no immediate reports of injuries.

Shell Chemicals’ site in nearby Deer Park was flaring, or burning off natural gas, after it lost steam because of severe weather, according to Shell spokesperson Curtis Smith.

“We are taking steps to minimize any noise, light, or smoke associated with this activity, though it’s expected to continue until the units are restarted,” Smith said via email. “There is no threat to the community, nor are there any indications a nearby tornado touched down within the Chemicals facility.”

The website PowerOutage.us, which collects live power outage data from utilities across the United States, reported about 123,000 Texas customers were without power Tuesday afternoon, mostly in the Houston area and surrounding counties.

It was the start of what’s expected to be a stormy day along the Gulf Coast. The Storm Prediction Center in Norman, Oklahoma, said areas along the coast from Houston to the Florida Panhandle could see tornadoes, strong winds and hail on Tuesday.

The storm system was also bringing snow and ice to much of the central U.S.

Schools and businesses were closed Tuesday and Wednesday across Oklahoma, which saw snowfall totals of between 1 and 6 inches (3 and 15 centimeters) across central and eastern parts of the state. Several school districts in southwest Louisiana dismissed students early Tuesday in anticipation of severe weather in the area.
