Heavy rains, strong winds, and suspected tornadoes ripped through central and southern Texas on Friday and Saturday as a powerful storm hit the region, causing multiple rivers to overflow their banks, forcing evacuations and leaving at least three people dead.

On Friday, one possible tornado touched down in Floresville, Texas, the Associated Press reported, launching a large trailer from a nearby RV park on to the roof of a three-story hotel and causing some minor injuries.

A second round of flash floods and tornadoes hit the state Saturday morning, flooding highways, underpasses, and local roads. Residents in many major counties were told by local officials not to travel if at all possible.

Less rain was expected by Saturday evening, but local officials warned people that the heavy storms have left bayous, creeks and ditches running full until Sunday morning, making them dangerous and hard to see as trick-or-treaters make their way out Saturday.

"These water superhighways are moving millions of gallons of stormwater out of our community to Galveston Bay," Harris County Flood Control District officials said in a statement. "Please keep trick or treaters out of roadside ditches and away from bayous and creeks - they are harder to see at night and are dangerous."
