🛡️ Tornado Safety

What to know before, during, and after a tornado

⚠️ Tornado Watch
Meaning: Conditions are favorable for tornado development
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.
⚠️ Step 1

Tornado Watch — Be Prepared

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.

🔍 Step 3

After a Tornado

Stay in your shelter until the warning expires. Check for injuries, avoid downed power lines, and watch for gas leaks. Document damage for insurance before cleanup.

Where to Shelter

✓ Best: Underground shelter or basement
✓ Good: Interior room on lowest floor
✓ Acceptable: Bathroom or closet (no exterior walls)
✓ If driving: Pull over, get below road level in a ditch
✗ NEVER: Stay in a mobile home — leave for sturdy building
✗ NEVER: Shelter under a highway overpass
