If a storm threatens, the single most important thing you can know in advance is whether you're in an evacuation zone — and which one. Looking it up before the season, not during a warning, is what makes an orderly evacuation possible.
What an evacuation zone actually is
Evacuation zones are set by your local and county emergency-management officials, and they're based mostly on storm-surge risk — where rising water is expected to reach — not on wind. That's why the zones hug the coast, bays, and low-lying inland waterways. They're usually labeled by letter (A, B, C…) or by level, with the most surge-prone areas evacuated first.
Zones are about water, not the storm's category
Officials call evacuations by zone, based on the surge forecast for the approaching storm — so a “lower-category” storm can still trigger an evacuation of the most vulnerable zones. When your zone is called, that decision has already accounted for how bad the water will be. Don't second-guess it against the category number.
How to find yours
- Search your county or state emergency-management website for “evacuation zone” — most offer a look-up by address.
- Many coastal states have an official app or a “Know Your Zone” tool.
- If you can't tell, call your local emergency-management office — before a storm, when they have time to help.
Have a plan before you need it
- Know where you'd go. Surge evacuations usually mean moving just a few miles inland or to higher ground — out of the zone — not hundreds of miles. Pick a destination (a friend's home, a shelter) in advance.
- Know your route, and a backup, since roads can flood.
- Plan for everyone, including pets and anyone with medical needs, and leave early — once winds arrive, it's no longer safe to go.
Bottom line
Evacuation zones are about where the water goes. Find your zone today through your local emergency-management office, make a simple plan for where you'd go and how, and when officials call your zone — leave.
