Before — Plan Your Shelter

Tornadoes strike with little warning. Knowing where to go before they hit is essential.

#Do this
1Identify your safe room (basement, interior room, lowest floor)
2Practice tornado drills -- go to safe room in under 60 seconds
3Keep helmets or thick blankets near safe room for head protection
4Keep sturdy shoes in safe room
5Know the difference: Watch (conditions possible) vs Warning (spotted)
6Enable weather alerts on your phone
7Trim weak branches and dead trees near your home
8If in mobile home, identify nearest sturdy building for shelter

During — When a Tornado Warning Is Issued

You may have only minutes. Act immediately.

#Step
1Go to your safe room IMMEDIATELY -- basement or interior room on lowest floor
2Get under sturdy furniture and cover your head and neck
3Stay away from windows, doors, and outside walls
4If in a mobile home, leave and get to a sturdy building or lie flat in a ditch
5If in a car, drive to nearest sturdy building -- do NOT try to outrun a tornado
6If caught outdoors, lie flat in the lowest area and cover your head
7Do NOT shelter under highway overpasses -- wind tunnels increase danger
8Cover yourself with a mattress, thick blankets, or sleeping bag

After — After the Tornado Passes

Remain cautious. Structural damage may not be immediately visible.

#Step
1Stay in your safe room until the all-clear is given
2Watch for fallen power lines, broken glass, and nails
3Do not enter damaged buildings until inspected
4Check for gas leaks -- if you smell gas, leave and call 911
5Use flashlight to inspect, never candles or matches
6Help trapped or injured neighbors if safe to do so
7Document damage with photos for insurance
8Beware of secondary tornadoes -- storms can produce multiple
9Listen to local news for updates and shelter locations

Questions people ask

Where is the safest place to shelter?

During a tornado, get to the lowest floor, most interior room, away from windows:

  • Best: Basement or storm cellar
  • Good: Interior bathroom or closet on the lowest floor (plumbing in walls adds structural support)
  • Acceptable: Under a sturdy table or stairwell

Never shelter in: Mobile homes (evacuate to a sturdy building), cars, or large open rooms (gyms, auditoriums).

Protect your head and neck with a helmet, pillows, or a mattress. Flying debris causes most tornado injuries.

What is the difference between a watch and a warning?

This distinction can save your life:

  • WATCH = Conditions are favorable for tornadoes. Be prepared. Review your plan, know where your shelter is, stay alert to weather updates.
  • WARNING = A tornado has been sighted or detected on radar. Take shelter IMMEDIATELY. You may have only 10-30 minutes, sometimes less.

Think of it this way: A watch means "watch the sky." A warning means "take action NOW."

How do I protect windows during a storm?

For hurricane/severe storm preparation:

  • Plywood shutters (5/8" minimum) are the most effective and affordable option. Pre-cut and label them for each window.
  • Hurricane shutters (permanent installation) are ideal if you're in a storm-prone area
  • Do NOT tape windows — this is a myth that doesn't work and creates larger, more dangerous shards

During a tornado, stay away from windows entirely — there's no time or point in protecting them. Get to your interior shelter.

What supplies do I need in a storm shelter?

Keep these in your shelter area (basement, safe room, or interior closet):

  • Helmets for everyone (bike helmets work great)
  • Flashlight with extra batteries
  • Battery-powered weather radio (NOAA)
  • Sturdy shoes (for walking through debris after)
  • Phone and charger
  • Whistle (to signal if trapped)
  • First aid kit
  • Water and snacks
  • Blankets or sleeping bags

Store everything in a waterproof container. Check supplies every 6 months.

How do I stay safe if caught outdoors?

If you're caught outside during a tornado with no shelter nearby:

  • Get to the lowest ground possible — a ditch, ravine, or low area
  • Lie flat and face down, protecting the back of your head with your hands
  • Stay away from: Trees, cars, bridges, and overpasses (they create wind tunnels)
  • Do NOT try to outrun a tornado on foot

This is a last resort — always seek a sturdy building if possible. If you're in a car, drive at right angles to the tornado's path to get out of its way. Never park under an overpass.
