Storm chasers armed with video cameras transmitted images showing several funnel clouds that dropped from a supercell thunderstorm as it passed south of El Reno and toward downtown Oklahoma City. Police urged motorists to leave the crosstown Interstate 40 and seek a safe place.
Damage was reported in Canadian County, west of the city, and television cameras showed debris falling from the sky and power transformers being knocked out by high winds.
The Oklahoma Highway Patrol said a number of motorists were injured and that a few were missing. Numerous vehicles were damaged, leaving motorists stranded on the sides of roads, Trooper Betsy Randolph said.
The Storm Prediction Center in Norman, Okla., had forecasted a violent evening for the area from the Texas border to near Joplin, Mo. Forecasters warned of a "particularly dangerous situation," with strong tornadoes and hail the size of grapefruits: 4 inches in diameter.
