The risk level was categorized as “high” in and around Oklahoma City and Lawton and a threat level for tornadoes was 5 out of 5.
CNN meteorologist Brandon Miller said that violent tornadoes account for 0.5 percent of all tornadoes but have inflicted about 50 percent of all deaths from tornadoes.
“Tornadoes could occur well after dark, making this situation potentially even more deadly,” said CNN meteorologist Dave Hennen.
Over 2 million people are in the areas under a tornado watch, Miller added. More than 50 million are at risk of other severe weather such as high winds and flash flooding.
The National Oceanic and Atmospheric Administration said that there is a high risk of flash flooding in and around Oklahoma City and a medium risk of flash flooding in southern Kansas, southwestern Missouri, northwestern Arkansas, and a portion of northern Texas. A slight risk exists in other states.

Know where to go when a Tornado warning is issued for your area. Under an overpass is literally “the worst” place to be. Get inside a storm shelter or well-constructed structure and find the lowest central location you can to take shelter. pic.twitter.com/7txDIVCwJt
