A fast moving storm has dumped heavy rain in the Denver area, causing minor street flooding and trapping some people in their cars in high water.
Denver fire officials tell KUSA-TV that some people were rescued from submerged cars in north Denver Thursday afternoon. Tornado sirens went off, but it wasn't clear if a funnel cloud was spotted. The National Weather Service said up to 2 inches fell in less than an hour in the northeast Denver area.
South of Denver, lightning knocked out power for about an hour to 240 utility customers in Colorado Springs. The Gazette reports lightning also ignited a small fire at a house in Fountain in El Paso County.
There were no immediate reports of injuries. Heavy rains were also reported in southern Colorado.
