Hurricane aftermath has its own dangers, such as downed lines, contaminated water, spoiled food, and homes that may not be safe to re-enter. The first 24 hours require patience, prudence, and a clear hierarchy of priorities. This guide covers the most important things you should do after a hurricane. Learn to check your home, handle water and food safely, cope with outages, avoid cleanup hazards, document damage, and get disaster assistance.
The First 24 Hours After a Hurricane
The first few hours after a hurricane can feel strangely calm. Your first priority should be your personal safety. Don't feel you need to check out your property right away. Local officials may still have evacuation orders or movement restrictions in effect.
Wait for officials' all-clear
Knowing what to do after the hurricane starts with waiting for official guidance. The storm may have passed, but hazards can remain.
Stay in the shelter where you are until local officials say it is safe to go outdoors. Flying debris and gusty winds can still be dangerous even after the rain moves out and the sky opens up.
Many of the injuries that occur right after a storm are due to downed power lines. Treat every line as if it were live, and keep children and pets well away from anything on the ground.
Storm surge and flooding cause most hurricane deaths, not wind, and knowing what actually makes a hurricane's landfall so destructive explains why officials ask people to hold off before heading outside to look around.
Check your surroundings
Don't start cleanup immediately when officials give the all-clear. Walk slowly and look for obvious dangers first.
Look out for:
Fallen electrical wires
Nails sticking up and broken glass
Unstable trees and tree branches
Floodwater standing
Broken gas lines
Fences/structures collapsed
Cracks in the Foundation
Sagging roofs/ceilings
Strong smells of chemicals or fuel
During this first inspection, keep children away from the property. Pets should also remain indoors or in a safe place until dangers are identified. Understanding what happens after a hurricane helps explain why this cautious approach matters. The storm itself may be gone, but several secondary hazards can remain.
Once it's actually safe to move around outside, the next question most households face is whether the water coming from the tap is safe to use.
Is Your Tap Water Safe? Boil Water Advisories and Food Safety
Hurricane damage to water systems can be severe. Flooding can contaminate wells, and pressure losses can affect municipal water systems. Also, physical damage or loss of electricity may happen at treatment facilities. That makes water safety one of the first things to check once you are back home.
Follow local water advisories
Hurricanes often cut pressure on water lines and damage treatment plants, allowing bacteria and other contaminants into the system. That's when local utilities issue a boil water advisory.
During an advisory, water should be brought to a full rolling boil for at least one minute (three minutes at elevations above 6,500 feet) before drinking, cooking, or brushing teeth.
If unsure of the local water supply, use bottled water whenever possible.
Don't assume clear-looking water is safe to drink after flooding.
Ice made from contaminated water should be thrown out as well.
Protect refrigerated and frozen food
Food safety math gets more specific once the power's actually out for a while, and exactly how long refrigerated and frozen food actually stays safe breaks it down by appliance and by hour.
In the event of power outages, a stocked kitchen can quickly become a health hazard.
Both FoodSafety.gov and the USDA recommend that you toss out any perishable food that has been at a temperature above 40°F for two hours or more if the power has been out for more than four hours, rather than risk a foodborne illness.
A full freezer will keep a safe temperature for something like 48 hours, only 24 if it is half full. So grouping things together and keeping the door shut buys real time.
Don't experiment with untested foods to see if they are safe.
Discard food that may have come into contact with floodwater.
Don’t keep cans that are puffy, leaking, badly damaged or punctured.
None of that food safety math matters much if the power itself doesn't come back for days, which happens often enough after a hurricane that it's worth planning ahead of time.
Keeping Essentials Running During the Post-Hurricane Outage
After a major hurricane, restoring power can take hours, days, or longer. That’s not really about powering everything. It's more about keeping the essential systems going.
Prioritize the circuit that matters
U.S. utility customers faced an average of 11 hours of power outages in 2024, almost double the average over the last decade. It was primarily due to Hurricanes Beryl, Helene, and Milton.
After Helene alone, South Carolina customers were without power an average of 53 hours, and some communities in western North Carolina waited more than two weeks for restoration.
The top priority list usually includes a sump or well pump, refrigerators, phones, and medical devices.
For households that lose power almost every storm season, how long a typical outage actually tends to last is worth checking before deciding how much backup capacity actually makes sense.
Choose backup power based on the outage
Each home will require a different amount of backup capability. While a portable power station can handle the essentials without powering an entire house, whole-home systems are more logical if you have frequent or lengthy outages. They can keep the essential circuits alive when the grid is out.
DELTA Pro Ultra X covers a full home waiting for a multi-day restoration, while DELTA 3 Max is small enough to grab fast if a hurricane forces an evacuation.
The aftermath of hurricane conditions can last well beyond the initial storm. Reliable backup power can help households manage that period with fewer disruptions. However, a lot of physical cleanup follows a hurricane that comes with hazards of its own.
Cleanup Hazards: Debris, Mold, and Generator Safety
Homeowners often go into cleanup mode after the storm passes. That’s understandable, but rushing can cause new injuries and damage. The most effective is to divide inspection and cleanup. Identify the hazards first. Choose what you can handle safely on your own.
Treat floodwater as contaminated
Water that has settled can hide sharp objects, raw sewage, chemicals, and downed electrical lines, so it's worth wearing rubber boots, gloves, and eye protection even if you just want to take a quick look.
Do not walk in water near electrical equipment or outlets.
Keep children and pets out of floodwater.
Do not operate electrical equipment in wet conditions.
Act quickly against mold
EPA guidance says anything that gets soaked needs to be removed or dried out quickly because mold can start to grow on wet drywall, carpet, and insulation in 24 to 48 hours.
Take away wet materials that won't dry properly.
Increase ventilation if conditions outside permit.
If it is safe to have power, use fans or dehumidifiers.
Avoid disturbing large areas of mold without proper protection.
Use generators carefully
Portable generators are one of the leading causes of carbon monoxide poisoning deaths after a storm, and the Consumer Product Safety Commission says a single running generator emits about as much carbon monoxide as hundreds of cars idling.
The CPSC recommends running a generator outdoors only, at least 20 feet away from any window, door, or vent, with exhaust pointed away from the house at all times.
Never run a generator in a garage, basement, shed, or enclosed porch.
Keep generators away from doors and windows.
Install working carbon monoxide alarms in your home.
Refuel only when the generator has cooled down.
Getting this step wrong is one of the most common post-storm mistakes, and the specific setup mistakes that turn a generator dangerous covers exactly what to avoid before pulling the starter cord.
With immediate hazards under control, the next thing most homeowners have to sort out is what their insurance will actually pay for.
Documenting Damage and Filing an Insurance Claim
Documenting the damage can impact the progress of a hurricane claim. If it is safe to do so, take photographs before beginning major cleanup.
Document everything before cleanup
Adjusters use this evidence extensively when a claim is filed. Before you move or discard anything, take photos and videos of every room, the roof, the yard, and any damaged property.
Take pictures of the damage from different angles.
Save receipts for emergency repairs and temporary housing.
Make a list of your damaged or lost property.
Damaged goods, where practical, shall be retained until advised by the insurer.
Record serial numbers and purchase details for major equipment.
Understand the flood coverage gap
Most standard homeowners policies cover wind damage, but they don't cover flooding. That generally requires a separate policy through the National Flood Insurance Program or a private flood carrier.
Contact the insurance company as soon as you can after a storm. Claims filed early tend to move faster. Many carriers extend filing deadlines during a declared disaster.
The FTC, DOJ, and CFPB have all warned that scams and price gouging skyrocket after major hurricanes, so it's wise to check out a contractor's license before signing an agreement or paying a deposit.
Knowing where that coverage gap sits matters before a storm even forms, and what a standard homeowners policy actually leaves out breaks down where flood coverage has to pick up the difference.
Insurance rarely covers everything, which is where federal and nonprofit disaster assistance programs come in for whatever's left over.
Getting Help: FEMA Assistance and Long-Term Recovery
Hurricane recovery usually isn't over in the first 24 hours. Some families can take months. Federal aid, insurance, non-profits, and community programs may all play different roles.
Request federal disaster assistance
Homeowners and renters in a federally declared disaster area can apply for FEMA's Individual Assistance program at DisasterAssistance.gov to help pay for temporary housing and basic repairs not covered by insurance.
FEMA aid is not a substitute for insurance. It is intended to cover basic needs that insurance and other assistance still leave short, and applying for it will not reduce an existing benefit.
The American Red Cross and local nonprofits often establish shelters, provide meals, and offer case management well before federal aid arrives. They are worth contacting in addition to a FEMA application.
Keep copies of applications, receipts, claim numbers, and official correspondence.
Follow up if your situation changes during recovery.
Expect a longer recovery
It is more important to pace repairs against a realistic budget than to rush them. Rebuilding a single home after a major hurricane can take months, and rebuilding the infrastructure of an entire community can take years.
Make repairs that will prevent further damage to the property. Structural issues, electrical hazards, roof openings, and water intrusion should be an early focus.
Some homeowners use the rebuild itself as a chance to upgrade rather than just replace, and how solar and battery backup actually fit into a post-storm rebuild looks at what that upgrade tends to cost and return over time.
Conclusion
Hurricane aftermath days carry their own risks. Understanding what happens after hurricanes helps you approach cleanup with the right priorities. The safest way is to go slow and listen to official advice. Do not leave your shelter or go home until you hear the all-clear. Document damage before major cleanup begins. Assume all downed power lines are live. Keep generators outside and away from openings.
If the power is out for a long time, backup power can keep critical appliances and systems running. The DELTA Pro Ultra X is built for whole-home backup needs, and the DELTA 3 Max is a more portable option for essential devices and evacuation situations. For households focused on long-term hurricane recovery, preparing backup power before storm season can make extended outages easier to manage.
FAQs
How long does it typically take for power to come back after a hurricane?
Power restoration from hurricanes varies widely. Smaller outages can last for hours. Major storms can knock out power in communities for days or weeks. Critical infrastructure is usually the first to get power back when utilities restore power.
Is it safe to drink tap water right after a hurricane?
Not necessarily. Follow your local utility's guidance. If a boil water advisory is in effect, bring water to a rolling boil for at least one minute; otherwise tap water may be safe. When in doubt, use bottled water.
Does homeowners insurance cover hurricane damage?
That depends on the type of damage and your specific policy. Most common homeowners policies do cover wind damage. Standard homeowners insurance policies generally don't cover floods. Separate coverage may be available through federal or private flood insurance.
How far from the house should a generator be placed during a power outage?
The CPSC recommends placing portable generators at least 20 feet away from the house. Do not put the generator near windows, doors, or vents. Direct exhaust away from the structure.
What's the first thing I should do when I get back to a hurricane-damaged home?
First, ensure the area has been cleared for re-entry by officials. Then look around without rushing in. Check for downed power lines, gas leaks, structural damage, standing water, and other hazards. Do not enter if the building looks unstable. Secure the property, take photos, and document damage. If possible, call your insurance company before you do major cleanup.
