Hurricane power outage prep

Why hurricanes cause the longest outages

The EIA reports that US electricity customers averaged about 11 hours without power in 2024, the most in a decade, and that major events, primarily hurricanes Beryl, Helene and Milton, accounted for 80% of those hours. South Carolina customers averaged nearly 53 hours. The Department of Energy reported that Helene's outages peaked at about 4.6 million customers across the region on September 27, 2024.

Hurricanes damage the distribution system at scale: poles snap, lines come down under trees, substations flood. Crews often have to rebuild lines rather than repair them, and they can only start once winds drop and roads are passable. Inland areas are not immune; Helene caused severe damage hundreds of miles from the coast.

Early in the season (do this now)

• Know your evacuation zone and route. If you are told to evacuate, go. No outage plan replaces that.
• Build your kit with the 72-hour and two-week checklists.
• Decide on backup power. A portable power station is quiet and safe indoors; a generator runs longer on fuel but must stay outdoors. The backup power calculator helps you size either.
• If you plan to connect a generator to home circuits, have a licensed electrician install a transfer switch or interlock now, not during the storm.
• Photograph your home and belongings for insurance.
• Get a battery or hand-crank NOAA weather radio. See our emergency radio picks.
• Install battery-powered CO alarms. Generator-related CO poisoning spikes after storms.

When a storm is forecast (72–48 hours out)

1. 01Fill vehicles with fuel and get cash; card readers and pumps need power.
2. 02Charge every power bank, laptop, phone and power station.
3. 03Fill bathtubs and large containers with water for flushing and cleaning (not drinking unless the containers are food-safe).
4. 04Turn the fridge and freezer to their coldest settings and fill empty freezer space with containers of water to make ice.
5. 05Refill prescriptions and make a plan for medications that need refrigeration.
6. 06Bring in or tie down outdoor furniture, grills and propane tanks.
7. 07Store generator fuel safely outside the living space and away from ignition sources.

During and after the storm

• Stay inside, away from windows, until officials say it is safe.
• Stay away from downed lines, and treat every line as live. Report them to your utility.
• Do not walk or drive through floodwater.
• Keep the fridge and freezer closed. Ready.gov and the FDA say about 4 hours for the fridge, about 48 hours for a full freezer and about 24 hours for a half-full one.
• Listen to local officials for boil-water notices.

Generator safety after hurricanes

Carbon monoxide is one of the most serious risks after a hurricane, when many people run generators for the first time. The CDC says more than 400 Americans die from unintentional CO poisoning every year; CPSC links more than 100 deaths per year to portable generators.

Staying cool without power

Post-hurricane heat is a serious health risk, especially for older adults, infants and people with chronic conditions. Air conditioning usually needs far more power than a portable power station can supply for long, so focus on the basics:

• Run battery or USB fans; a power station can run a small fan for many hours.
• Close blinds on sun-facing windows during the day and open windows at night if it is safe.
• Drink water regularly and avoid strenuous cleanup in the hottest part of the day.
• Know where your local cooling centers are, and use them.

Sizing backup power for a hurricane outage

Make a list of what you must run and estimate daily energy in watt-hours (Wh): watts multiplied by hours used. Check each device's label or manual for its real wattage. A worked example:

In that example, a roughly 1,000 Wh power station covers about a day and a half, longer if you recharge it with solar panels. A full-size refrigerator adds a large, variable load (check the label or measure with a plug-in meter), which is why many households pair a power station with a generator or solar. The backup power calculator walks through this math for your home.

No. 1Power station

Anker SOLIX C1000 Portable Power Station

Best for: Running a fridge, lights, phones and a CPAP through a one- or two-day outage

• 1,056 Wh capacity (up to 2,112 Wh with the matching expansion battery)
• 1,800 W continuous / 2,400 W surge AC output
• LiFePO4 battery chemistry
• 6 AC outlets
• 28.44 lb

Tradeoff

• · At about 28 lb it is a carry-to-the-car unit, not a grab-and-go bag item.

No. 2Emergency radio

Midland ER310 Emergency Crank Weather Radio

Best for: A household weather radio with several ways to stay powered

• Power: solar, hand crank, 3,500 mAh rechargeable Li-ion, or 6 AA batteries
• NOAA weather band; alerts sound when issued on your local channel
• LED flashlight with SOS beacon
• USB output to top up a phone

Tradeoffs

• · Midland notes the design dates to the early 2000s and may not charge newer phones (iPhone X and later) reliably. Weather alerts are not SAME county-coded.
• · Midland's FAQ notes solar tops up a charged battery rather than reviving a dead one
• · Micro-USB charging rather than USB-C

No. 3Lantern

Lepro 1500lm Battery Powered LED Camping Lantern

Best for: Bright, flame-free room light that runs on stored batteries

• 1,500 lumens, dimmable (manufacturer rating)
• Runs on 3 D alkaline batteries (not included); not rechargeable
• Up to 12 hrs at 1,500 lm (manufacturer figure)
• IPX4 water resistance; daylight, warm, full and flashing red modes

Tradeoff

• · Not rechargeable, so stock spare D cells; lumen and runtime figures are self-reported.

No. 4Water filter

MSR AutoFlow XL Gravity Filter 10 L

Best for: Filtering water for a whole household if tap water is unsafe

• 10 L reservoir; hang it and gravity does the filtering
• 1.75 liters per minute; cartridge rated for 1,500 liters
• 0.2-micron hollow fiber: removes bacteria (99.9999%) and protozoa (99.9%) per MSR
• Meets EPA standards and NSF Protocol P231 for bacteria and protozoa (manufacturer claim)
• 12 oz; not effective against viruses or chemicals (maker)

Tradeoffs

• · Not rated for viruses or chemicals. CDC advises disinfecting filtered water when viruses are a concern, and no filter makes fuel-contaminated water safe.
• · Flow slows as the bag empties

After power returns

• Check food: discard perishables that were above 40°F for more than 2 hours, and when in doubt, throw it out (FDA, CDC).
• Have an electrician inspect any wiring or appliances that were flooded before using them.
• Restock your kit and recharge every battery for the next storm.
