Hurricane Preparedness Checklist for the 2026 Season

The 2026 Atlantic hurricane season starts June 1. Colorado State University's April forecast calls for 13 named storms, 6 hurricanes, and 2 major hurricanes, with El Niño expected to suppress activity modestly. AccuWeather's range sits at 11 to 16 named storms. "Below normal" is not "safe." A single storm making landfall on your county ends the season for you.

This checklist is built for action, not reassurance. It assumes you have six weeks to prepare and that a Category 2 or higher storm will cut power to your home for a week or more. According to the U.S. Energy Information Administration, Hurricane Helene knocked out power for 5.9 million customers across ten states in September 2024. Helene was not a surprise. Neither is the next one.

The new forecast cone matters for planning

NOAA announced on April 16, 2026, that the National Hurricane Center will issue updated forecast cone graphics this season. The experimental cone uses ellipses anchored at each forecast point and captures 90% of track possibilities, up from the traditional 67%. Inland tropical storm and hurricane watches will also appear on the cone for the first time.

What this changes for you: the cone is wider and reaches further inland. If you live within 150 miles of the coast, stop assuming you are outside the risk zone because the center line of a storm misses your county. Inland flooding from Helene killed more people than the storm surge did.

14 gallons of water per person, not three

FEMA's minimum evacuation water supply is one gallon per person per day for three days. For home storage, FEMA recommends two weeks. That math is 14 gallons per person. A family of four needs 56 gallons. The common mistake is treating the three-day evacuation number as the shelter-in-place number.

Storage options ranked by cost and reliability:

• Seven-gallon rigid containers (roughly $20 each). Stack two deep on a shelf.
• 55-gallon food-grade drums with a bung wrench and siphon pump. One drum covers a family of four for nearly two weeks.
• Commercially bottled water in original sealed containers. Rotate every 12 months.
• A bathtub bladder (WaterBOB or similar) for 100 gallons of pre-landfall fill. Useless after the fact.

Every gallon should be sealed and stored away from sunlight. Add unscented household bleach at five drops per gallon if you bottle tap water yourself, per EPA guidance. Store a backup purification method: a gravity filter rated for at least 1,000 gallons, or calcium hypochlorite pool shock for long-term treatment. For more on treatment ratios and failure modes, see our offline survival reference guide.

Food that does not require a refrigerator

Refrigerated food spoils four hours after the power fails, per USDA guidance. A freezer holds for 48 hours if full and unopened. Your two-week food plan cannot depend on either.

Build around shelf-stable calories:

• Canned protein: tuna, chicken, salmon, beef stew. Count 1,500 to 2,000 calories per person per day.
• Rice, oats, pasta. Cheap bulk calories with 25-year shelf life when stored in mylar with oxygen absorbers.
• Peanut butter, honey, olive oil. High calorie density, long shelf life.
• Electrolyte packets. Humidity and physical exertion during cleanup burn sodium fast.

Keep a manual can opener attached to the pantry with a zip tie. The most common missing item in surveyed hurricane kits is a can opener. If you take one thing from this section, tie the opener to the shelf tonight.

Power and communications during a multi-day outage

The EIA reported that U.S. electricity customers experienced an average of 11 hours of interruptions in 2024, nearly double the prior decade's average. Eighty percent of those hours came from Hurricanes Beryl, Helene, and Milton. South Carolina customers averaged 53 hours of outage time. In the South, the average longest outage per customer reached 18.2 hours by mid-2025 according to J.D. Power data.

Plan for 168 hours, not 18.

Tiered power strategy:

1. Battery banks for phones, headlamps, and radios. Two 20,000 mAh banks per adult is a reasonable baseline. Keep them at 80% charge during hurricane season.
2. A solar panel in the 60 to 100 watt range with a portable power station between 500 and 1,500 watt-hours. This runs a CPAP machine, a small fridge, or a laptop for days as long as you get sun.
3. A dual-fuel generator for high-load needs. Size it to run your refrigerator, a few fans, and medical devices, not your entire house. Store 10 gallons of fuel with stabilizer. Run the generator outdoors only. The CDC reports over 900 carbon monoxide deaths since 1999 linked to portable generators, with spikes during hurricane recovery.

Communications should not rely on a charged cell phone. Cell towers often lose backup power within 24 hours. A NOAA weather radio with SAME alerts, a handheld HAM or GMRS radio, and a written list of family ICE contacts will keep you functional when the network does not. For deeper coverage, see long-term power outage preparedness.

Documents, identity, and cash

Flooding destroys paper. A Category 3 storm surge averages 9 to 12 feet of water above normal tide, per NOAA historical data. Anything below the second floor is a loss.

Waterproof document set, kept in a fire-rated safe or a sealed dry bag in a go-bag:

• Passports, driver's licenses, Social Security cards
• Birth certificates, marriage certificates, adoption records
• Insurance policies with declarations pages, including flood insurance
• Property deeds, vehicle titles, mortgage documents
• Current prescription list with dosages and prescribing physicians
• Recent photographs of every room in the house for claims purposes
• A USB drive with encrypted copies of everything above

Keep at least $500 in small bills per adult. ATMs and card readers fail when power does. Gas stations during the Helene recovery were reportedly refusing cards within 36 hours of landfall in parts of western North Carolina.

A pre-loaded digital library on a USB drive is the kind of thing that quietly matters during a week-long outage. The Deadnet drive carries FEMA guides, military field manuals, and an offline AI assistant that runs without internet, so you can look up wound care, water purification ratios, or generator troubleshooting when the cell network is down. Not a replacement for physical supplies, but a reference library that survives the power cut.

Evacuation vs. shelter-in-place

The wrong call costs lives in both directions. Evacuating into gridlocked traffic during a storm surge kills people. Sheltering in a flood zone kills people faster.

Evacuate if any of these are true:

• You live in a FEMA-designated evacuation zone (check your county's zone map before the season, not during a warning).
• You are in a mobile home, regardless of category. Manufactured housing cannot handle sustained winds above 80 mph.
• You are in a storm surge inundation area forecast for any category of hurricane.
• Local authorities issue a mandatory evacuation order.

Shelter-in-place is viable only if your structure is rated for the forecast wind speed, you are above the surge line, and you have the supplies listed in this guide. Bring outdoor furniture inside or tie it down. Close interior doors to compartmentalize pressure. Move to an interior room on the lowest floor above the flood line when the eyewall approaches.

If you evacuate, leave 72 hours before landfall. Traffic counts on I-10 and I-95 during Milton showed 36-hour gridlock within 100 miles of the coast. Fuel stations run dry 48 hours before landfall along major evacuation routes. Top off your tank when the cone first includes your county.

Your vehicle is a 48-hour shelter

A vehicle with a full tank can provide air conditioning, charging, and radio access for roughly 48 hours of intermittent idling. Treat it as a mobile base camp during evacuation or a fallback shelter if your home loses power for days in extreme heat.

Vehicle pre-season checklist:

• Tires at proper pressure, including the spare.
• Oil and coolant topped off.
• 10 gallons of stored gasoline at home with PRI-G stabilizer, rotated every 12 months.
• Jumper cables or a portable jump pack.
• Paper maps of your state and surrounding states. Google Maps does not work without cell service.
• Two weeks of medication in the glove box, rotated monthly.

The 72-hour window before landfall

Most preparation windows are tighter than people expect. The cone shows three to five days of notice. Useful action compresses into the final 72 hours.

T-minus 72 hours:

• Fill all water containers. Top off the bathtub bladder.
• Full tank of gas, plus reserve cans.
• Withdraw cash in small bills.
• Charge every battery bank, power station, and device.
• Review the evacuation decision with your household. Commit one way or the other.

T-minus 48 hours:

• Bring in or tie down anything the wind can throw. This includes grills, patio furniture, planters, trash cans, and children's toys.
• Board or shutter windows.
• Fill prescriptions. Pharmacies close early.
• Photograph every room for insurance.
• Pre-stage the go-bag at the door.

T-minus 24 hours:

• Turn the refrigerator and freezer to the coldest setting. Fill empty space with water bottles to hold temperature longer.
• Charge phones to 100%, set to low power mode.
• Fill the bathtub with water for sanitation.
• Unplug non-essential electronics to protect against surges when power returns.
• If evacuating, be on the road. Not an hour before landfall. Not at the evacuation order. Now.

The first 48 hours after

The storm passes. The danger does not.

Ready.gov and CDC guidance is consistent on post-storm hazards: downed power lines kill, standing water carries sewage and chemicals, and structural damage is not always visible. Assume every wire is live. Assume every puddle is contaminated. Assume every damaged building can collapse further.

Priority order in the first 48 hours:

1. Account for everyone. Family, neighbors, especially the elderly.
2. Check for gas leaks by smell, not by flame. Shut off the main if you smell gas.
3. Document damage with photos and video before cleanup. Insurance claims depend on pre-cleanup documentation.
4. Boil water for at least one minute before drinking, or treat with bleach at eight drops per gallon, per CDC guidance. Municipal water often carries pathogens after flooding.
5. Check neighbors and plan mutual aid. During the Helene recovery, informal neighborhood networks moved food and fuel before federal aid arrived.

Do not run a generator in an enclosed space. Do not wade through flood water. Do not touch downed lines or anything in contact with them.

What most checklists get wrong

Every mainstream hurricane checklist lists the same items. The gaps show up after the storm.

• Most kits carry three days of water and call it done. FEMA's actual shelter-in-place recommendation is 14 days.
• Most kits assume cell service. It fails within 24 hours near landfall.
• Most people pack the go-bag during the warning. By then, ATMs are empty and shelves are stripped.
• Most people trust the cone's center line. The new 2026 cone was widened for a reason.
• Most people rely on a single power source. Solar, battery, and generator each fail in predictable scenarios. Layered redundancy is the only reliable approach.

A digital survival library on a physical drive addresses the cell service problem directly. The Deadnet USB includes 19 source documents, including FEMA disaster preparedness manuals and military field references, and a local AI assistant that answers questions without a network connection. Compared to a phone, it is the difference between a device that needs infrastructure and one that does not. See also our guide to building a digital survival library.

Do this today

Pick one item. Finish it before you close this tab.

If you have done nothing: buy 14 gallons of water per household member and store them in a closet. Total cost under $50. Time required: one trip.

If you have water already: check your FEMA evacuation zone at your county emergency management website. Write the zone number on an index card and put it on the refrigerator. Time required: five minutes.

If you know your zone: photograph every room of your house with your phone tonight. Email the photos to yourself. That single step will pay for itself ten times over if you file a claim.

The June 1 deadline is not a suggestion. Storms do not wait for readiness. Every item on this checklist takes longer than you think and costs less than you fear. Start with one.
