🛡️ Tornado Safety

What to know before, during, and after a tornado

⚠️ Tornado Watch

Be prepared to take shelter. Stay alert for changing conditions.

🌪️ Tornado Warning

Meaning: A tornado has been spotted or detected on radar

TAKE COVER IMMEDIATELY in your nearest safe shelter.

Conditions are favorable for tornados. Monitor weather alerts, charge your phone, and review your shelter plan. Move vehicles into garages if possible.

🌪️ Step 2

Tornado Warning — Take Cover NOW

A tornado has been sighted or indicated by radar. Move immediately to an interior room on the lowest floor (basement, bathroom, closet). Get under sturdy furniture. Stay away from windows.
