The drill is part of Missouri 2011 Severe Weather Awareness week, which runs from through this Friday.
According to the Missouri Department of Public Safety, once Missourians hear broadcast drill messages or outdoor warning sirens, they should practice seeking shelter. The safest shelter location is an interior room without windows in the lowest level of a building. Other safe locations for businesses and schools include basements, hallways, underneath staircases and designated tornado safe rooms. The drill is complete once everyone is accounted for in the designated shelters.
