Explainer: Tornado watch versus tornado warning

Scout out a safe place to take shelter in your home well before storms approach your location. The safest place is an interior room on the lowest level of the building. The goal is to put as many walls as possible between you and flying debris.

If you’re in a vehicle and a tornado warning is issued, pull over at the nearest sturdy shelter. Never try to outrun a tornado.

Residents in impacted areas are urged to keep cell phones charged ahead of the storm in case of any power disruptions or outages to receive weather alerts (click here to see how to turn on alert notifications from The Weather Network app).
