(3-Minute Steady Sound)

When you hear a steady 3-minute sound from the sirens, a tornado is imminent. A tornado has been sighted on radar by the National Weather Service or by a weather spotter. Immediate action is required.

If indoors, seek shelter in the lowest level of the building. Interior hallways are preferable. Stay away from windows.

If outdoors, take cover in the nearest ditch or low area away from power lines and trees. Do no stay in a car or attempt to outrun a tornado.
