Emergency crews rescued stranded motorists and several children in a house trailer from flooded Oklahoma City streets but were searching for a teenage boy swept away by a creek.

Oklahoma City Police say two teens were swept away by high water Tuesday when they either jumped or fell into the creek at a city park.

A 14-year-old was rescued downstream, but his 13-year-old companion hadn't been found Tuesday evening.

The National Weather Service issued a flash flood warning for several counties in the area after a storm system quickly dumped 2 inches of rain on some parts of the region. Some streets and parts of an interstate were closed.

Earlier, six people suffered minor injuries when high winds collapsed a tent that was to house a concert at an area casino.
