• Confirm the warning has been cancelled before opening the lid — a second circulation can follow the first within minutes.
  • Call 911 immediately for injuries or active hazards like gas leaks; use a non-emergency line for damage reporting so emergency lines stay clear.

Most tornado safety advice covers only the lead-up—watches, warnings, getting to shelter in time. Almost nothing covers what happens right after. The roar stops, and you are still sitting underground wondering if it is actually over. Those first ten minutes matter just as much as the ones before the storm. Most families have never thought through them.

Confirm It’s Actually Over Before You Move

The sound stopping does not mean the danger has passed. A larger supercell can produce multiple circulations, and a second tornado can follow the first within minutes. Before anyone opens the lid, grab a battery-powered or hand-crank NOAA weather radio, or a phone if signal has held up. Confirm that the warning has expired or that the storm has moved out of the area. If you cannot confirm it, wait longer than feels necessary. A few extra minutes underground costs nothing. Coming up into a second tornado costs everything.

Opening the Lid Safely

Once you feel confident it is safe to come up, open the lid slowly. Check what sits directly above and around it before you climb out. Debris fields after a tornado are unpredictable. A shelter that was clear when you went down can now have downed power lines, broken glass, or structural debris resting right at the opening. If the lid jams or will not slide, do not force it with everything you have. Check for debris caught in the track first. A breathable cover earns its keep here too—it keeps dirt and debris out of the lid mechanism, so nothing jams it shut at the exact moment you need it to open.

What to Check Before Anything Else

Once everyone is out, do a quick head count before anything else. It sounds obvious, but adrenaline makes people assume everyone is present without actually checking. After that, look for immediate hazards: downed power lines (arcing, popping and cracking noises), the smell of natural gas or a hissing noise, or structural damage that makes part of the house unsafe to enter. If you smell gas, skip the light switches and phones—anything that could spark. Get everyone away from the structure until utilities confirm it is safe.

When to Call for Help and Who to Call First

Call 911 immediately for any injury, trapped person, or active hazard like a gas leak or downed line. Do not wait to assess the full scope of damage first. For non-emergency damage, most areas run a separate line for utility companies to report downed lines or gas smells. Using it keeps 911 open for genuine emergencies. If you registered your shelter with local authorities, this is exactly what that registration exists for—responders triaging a damaged neighborhood know to check registered shelter locations first.

The Ten-Minute Mindset

None of this works well if it is the first time anyone in the family has thought about it. Walk through this sequence once, calmly, before you ever need it. That is what turns those first ten minutes from chaos into a routine. It is the same logic behind any family storm drill: rehearsed action holds up under stress in a way improvised action never does.
