Authorities have not confirmed any details related to the storms, but people told WFAA-TV they saw a man fall into a creek and get swept away about 7 pm.

The Dallas Morning News says two building collapses have been reported, including a partial cave-in at the Urban Inter-Tribal Center of Texas.

The newspaper also says Dallas Fire-Rescue rescued one driver trapped in high water near the city’s downtown, and several were stranded in flooded streets near Baylor University Medical Center.
