Violent storm system leaves 13 dead in Midwest in its wake Updated 12:54 p.m. A violent weather system that claimed 13 lives in Oklahoma and Arkansas amid tornadoes and flash floods gave way to clearing skies as the storms trekked toward the East Coast on Sunday. A tornado killed 10 people as it charged down Interstate 40 in Oklahoma City's western suburbs on Friday night, twisting billboards and scattering cars and tractor-trailers along a roadway clogged with rush-hour motorists leaving work or fleeing the storm's path. Officials say the tornado's victims include two children and eight adults. Flash floods in Arkansas killed three early Friday, including a sheriff attempting a water rescue. Deadly tornadoes strike Oklahoma City "The last two nights, I've been having hell," said Roy Stoddard, a truck driver from Depew, Okla., who was delayed by rising floodwaters at Little Rock, Ark. on Thursday. Then on Friday evening, he had to take shelter in a store's walk-in cooler during Friday evening's rush-hour in Oklahoma City as deadly weather approached. "I know what a tornado can do," Stoddard added. Damage from Friday night's severe weather was concentrated a few miles north of Moore, the Oklahoma City suburb pounded by an EF5 tornado on May 20 that killed 24 people. Next up, the system was approaching the densely populated Northeast. The Storm Prediction Center in Norman predicted a slight chance of severe weather in the Northeast on Sunday, mainly from the Washington, D.C., area to northern Maine. Hail and high winds were the chief threat, though a tornado could not be ruled out, forecasters said. Friday night's storm formed out on the prairie west of Oklahoma City, giving residents plenty of advance notice. When told to seek shelter, many ventured out and snarled traffic across the metro area - perhaps remembering the damage from May 20. Oklahoma Highway Patrol Trooper Betsy Randolph said roadways quickly became congested with the convergence of rush-hour traffic and fleeing residents. Friday night's victims included a mother and a baby sucked out of their car as the EF3 hit near El Reno. More than 100 people were injured by swirling debris, most with puncture wounds and lacerations, authorities said. A total of five tornadoes struck the Oklahoma City metro area, the National Weather Service said. Oklahoma wasn't the only state hit by violent weather Friday night. In Missouri, areas west of St. Louis received significant damage from an EF3 tornado Friday night that packed estimated winds of 150 mph. Northeast of St. Louis and across the Mississippi River, the city of Roxana was hit by an EF3 tornado, but National Weather Service meteorologist Jayson Gosselin said it wasn't clear whether the damage in both states came from the same EF3 twister or separate ones.
