A new round of tornadoes in Oklahoma has killed nine people and injured at least 75 others. Most of the damage and casualties occurred in the area around Oklahoma City, the state capital, where a huge tornado killed 24 people just 11 days earlier.
Many victims trying to escape Friday night's high winds and by highways suddenly found themselves directly in the path of powerful storms as the winds changed direction.
Severe flooding was a new problem in the Oklahoma City area Saturday, after a four-hour downpour that dropped 20 to 28 centimeters of rain.
Nearly 20 tornadoes were reported across the U.S. Midwest Friday - an area often known as "Tornado Alley" due to weather patterns at this time of year that increase the risk of severe storms.
Despite the damage and human cost, authorities said the latest tornadoes were much less powerful that the unusually large tornado that ravaged the Oklahoma City suburb of Moore on May 10. Moore felt some of the force of Friday's storms, but most of the damage was in and around El Reno, another suburb of the stated capital.
