Nine people have died in the Oklahoma City area after a violent burst of tornadoes and thunderstorms overnight.

Amy Elliott with the state Medical Examiner’s Office said Saturday morning that nine fatalities have been confirmed, including two children and seven adults. The previous overall total was seven deaths.

Hospital officials said at least 75 people were hurt during Friday night storms that hit at rush hour.

Dozens of tornado warnings were issued across a wide swath of the Midwest, including Oklahoma and Missouri, as a large storm front moved through the region. At least five died and dozens were injured.

Weather service meteorologists said Saturday that crews have to assess the damage before determining whether it was caused by tornadoes or severe thunderstorms. Cars were toppled on an interstate in the Oklahoma City area, and aerial images showed damaged to homes and businesses in the suburbs of St. Louis.

They said they expected to have an estimate by Saturday afternoon.

A cold front will move through the Plains and Midwest today, lessening the chances for severe weather
