Tips for finding shelter during a tornado

According to the NWS, acting quickly is key to staying safe during a tornado. Stay tuned to local news or a NOAA Weather Radio for continuous updates on tornado watches and warnings.

• If you are indoors: In the event of a tornado warning, seek shelter in your basement, safe room, or an interior room without windows. If possible, bring your pets along with you.

• If you are at your workplace or school: Comply with your tornado drill procedures and head to the designated tornado shelter area. Steer clear of windows and avoid large open spaces like cafeterias, gymnasiums, or auditoriums.

• If you are outside: If a tornado is approaching, seek immediate shelter inside a secure building. Remember that sheds, storage facilities, mobile homes, and tents are not safe options.

• If you are in a vehicle: Being in a vehicle during a tornado is not safe. The best course of action is to drive towards the nearest shelter. If finding a safe shelter is not possible, either crouch down inside your car and protect your head, or abandon your vehicle and seek shelter in a low-lying area such as a ditch or ravine.
