(CNN) -- Emergency crews in Oklahoma planned to continue a search Wednesday for a 13-year-old boy who they feared had drowned after falling into a creek swollen by heavy rains.
Two boys fell into the creek, called Lightning Creek, Tuesday. Emergency crews were able to fish a 14-year-old boy out of the rushing waters, said Cecil Clay, chief of the Oklahoma City Fire Department.
Flash flooding had been a problem Tuesday in the southern part of Oklahoma City, said Michealann Ooten, of the Oklahoma Emergency Management.
The heavy rains caused creeks to swell and stall cars in heavy flood waters that streamed into the streets.
Another person had to be rescued Tuesday from another creek in the area.
