As part of the state’s Severe Weather Awareness Week, the University of Iowa will participate in an annual tornado drill.

The drill will take place between 10 and 10:30 a.m. Wednesday. The outdoor warning sirens in Johnson County and around campus will sound a tornado watch for 30 seconds.

If severe weather threatens the area the day of the drill, officials will postpone the drill until Thursday at the same time.
