Hurricane Safety: What to Do Before, During, and After Landfall

Hurricane safety before, during, and after landfall: hurricane watches vs warnings, evacuation plans, water storage, and what to do when the storm passes.

If you keep one thing from this guide: when officials order an evacuation, go. Storm surge, not wind, is the number-one hurricane killer, and once roads clog it cannot be outdriven. Everything else is being ready before, safe during, and careful after.

Peak season, mid-August through October, is here. NOAA's 2026 outlook called for a below-normal year, and Tropical Storm Bertha still made landfall on the Gulf Coast in July. Below-normal is not low-risk. The time to prepare is the weeks before a storm gets a name.

Here's the phase-by-phase playbook.

Hurricane Safety Before Landfall

Preparation is a sequence of decisions, not a single shopping trip.

Know the Difference: Watch vs. Warning

Forecasters issue alerts in two tiers:

Alert Issued When What You Must Do
Hurricane Watch Hurricane conditions possible within 48 hours Review your plan, check supplies, secure outdoor items, know your zone
Hurricane Warning Hurricane conditions expected within 36 hours Finish preparations, fill fuel tanks, follow evacuation orders immediately

A watch is a heads-up. A warning is a deadline. A Category 1 storm pushes 4-5 feet of surge ashore, a Category 3 about 9-12 feet, and a Category 4 or 5 anywhere from 13 to over 18. Katrina's surge reached roughly 28 feet along parts of the Mississippi coast in 2005. Wind you can shelter from; moving water, you cannot.

Write the Family Plan

Your plan answers four questions before anyone asks them:

  1. Evacuate or shelter? Know your flood zone and whether your home is built to withstand the expected winds.
  2. Where do we meet? Two locations: one in your neighborhood, one outside the hazard area.
  3. How do we stay in touch? Designate one out-of-state contact. Local lines jam; long-distance calls often route around the damage.
  4. What's the route? Map two exit routes and check them against the latest evacuation zone maps.

Build the Kit

Your hurricane kit is the difference between inconvenience and crisis:

Fill Up Before the Wind Does

Gasoline and water vanish first when a storm approaches. Fill vehicle tanks and approved fuel containers 72 hours before the forecast window opens. Cash is second, ATMs and card readers fail without power.

Hurricane Safety During Landfall

Once the warning is out, execution begins: you either sheltered in place or evacuated.

Sheltering in Place

Move to a small interior room, bathroom, or hallway on the lowest floor, but not below ground. Basements flood first. Stay away from windows.

The Eyewall Is Not the End

The storm's eye brings sudden calm. Do not go outside. The back half carries winds that match the front, and the lull often lasts only minutes. Stay sheltered until officials confirm the storm has passed.

Never Run Generators Indoors

This kills more people than the wind itself. Generators, grills, and camp stoves produce carbon monoxide, a colorless, odorless gas:

  • Generators run outside only, at least 20 feet from doors, windows, and vents.
  • Never in a garage, even with the door open.
  • Install battery-powered CO detectors on every floor.
  • Wait for the generator to cool before refueling.

Windows: Tape Is Useless

Taping windows was a myth that cost thousands of panes. Hurricane-force debris shatters taped glass, and the tape creates larger, more dangerous shards. Boarding with plywood or installing impact-rated shutters is the only real protection, and it must happen before the wind arrives.

Hurricane Safety After Landfall

The storm ending is not the emergency ending. Floodwaters and downed infrastructure make the aftermath statistically deadlier than the landfall.

Floodwater Is Toxic

Do not wade, swim, or drive through floodwater. It's raw sewage, fuel, chemicals, and debris, and it hides live wires. Six inches stalls most vehicles; one foot floats them.

Treat Every Downed Line as Live

Assume every wire on the ground is energized, even after utilities report the grid is down. Stay at least 30 feet away and report to the utility.

Food Safety in an Outage

The 4-hour rule: perishables in a powerless refrigerator last about four hours; a full freezer holds its temperature roughly 48 hours. After that, throw it out. Our food and water storage guide has the full temperature tables.

Heat and Humidity After the Storm

With the grid down for days in late summer, survivors face 90°F-plus heat on top of the outage, a combination that turns a storm into a medical emergency for older adults. Budget backup power for cooling. Confusion, body temperature over 104°F, or sweating that stops means call 911. Our heat exhaustion vs heat stroke guide covers the full first-aid steps. Pets melt in the same heat: refill water twice a day, fan or damp-towel the crate, and no pavement walks until sunset. The hot weather pet safety guide has the full no-power cooling plan.

The Water Emergency

If authorities issue a boil-water advisory, follow it until they lift it. Boil first, then filter with a Sawyer Squeeze Water Filtration System if supplies are limited.

Insurance Claims Done Right

  • Photograph everything before cleanup.
  • Document with video as you walk through the property.
  • Make temporary repairs (tarp the roof, board windows) to prevent further damage.
  • File promptly and keep a log of every call, adjuster visit, and receipt.
  • Know your policy: standard homeowners policies exclude flood. Flood insurance has a 30-day waiting period; buy it in June, not in September.

Your Before-Landfall Checklist

Print this. Post it. Follow it.

The best hurricane safety plan is the one already executed before the warning goes up. Bertha proved in July that quiet forecast years still produce landfalls. Use the USGS readiness tools while you still have time.

Frequently asked questions

What should I do when a hurricane warning is issued?

Finish preparations within the warning window (usually 36 hours): board or shutter windows, charge everything, fill the bathtub with water for flushing, move outdoor furniture inside, and decide to evacuate if you are in a surge zone, leave early, in daylight.

What do I do if I'm told to evacuate during a hurricane?

Leave as early as possible. Take your go bags, documents binder, and a full tank of gas. Shelter inland with friends, a hotel outside the surge zone, or a designated public shelter, shelters accept pets only if the shelter is listed as pet-friendly, so check before you go.

What should I do after the hurricane passes?

Wait for the official all-clear before going out. Assume downed lines are live, do not drive through standing water, photograph damage before cleanup for insurance, and run generators outdoors at least 20 feet from the house, carbon monoxide kills more people after hurricanes than wind does.
