Hurricane Season Power Checklist: What to Do in June, at the Watch, and After Landfall

Hurricane preparation has a strange economics: everything is cheap and available in June and sold out or price-gouged at the watch. This checklist sorts the power side of preparedness by when — what to do at the start of the season (June 1 to November 30 in the Atlantic), at the 48-hour watch, at the 36-hour warning, during the outage, and in the days after, which are statistically the most dangerous part. It assumes a portable power station or solar generator is the backbone of your kit; if you don’t own one yet, that decision is the June section.

June: decide, buy, and test — while it’s all boring#

Size the battery for a multi-day outage. Hurricane outages are “the event” profile from our outage planning guide: essentials run about 2,200 Wh per day, so each covered day wants roughly 2,600 Wh of rated battery (2,192 ÷ 0.85). The practical readings of that math: a 2 kWh unit covers the first ~19 hours; a 3.6 kWh unit about a day and a half; genuine multi-day coverage comes from expansion batteries or solar panels, compared head-on in the home battery backup guide. Buy in June’s sales, not August’s shortages.

Plan solar for after the storm, not during it. A 400 W array returns roughly 1,200–1,600 Wh on a clear day — but close to nothing under a storm system. The honest model: battery capacity rides out landfall and the first grey day; panels earn their keep in the clear days that follow, when the grid is still down but the sky isn’t.

Buy the boring accessories now. Heavy-gauge (12 AWG) extension cords long enough to reach the fridge, a power strip, two fridge thermometers, rechargeable lanterns and headlamps, and a car-outlet charging cable for the station. This is the stuff that vanishes from shelves first.

Run the drill once. Charge the station, plug the fridge in for an afternoon, and watch it start. You’re confirming the compressor surge doesn’t trip the inverter and learning your real draw — the method is in the fridge-in-an-outage guide. Then store the unit charged; LiFePO4 holds for months.

At the watch: 48 hours out#

A hurricane watch means storm conditions are possible within 48 hours. This is the last calm window.

• Charge everything to 100% — the power station, phones, laptops, USB banks, headlamps, the car (a full tank is also a ~100 W generator via its 12V outlet). Modern LiFePO4 units fast-charge from empty in one to two hours, so there is no excuse for a partial battery at landfall.
• Freeze water bottles to pack every gap in the freezer. A full freezer holds safe temperatures for about 48 hours unopened — double a half-full one — and the bottles become drinking water as they thaw.
• Re-test the fridge on the station for ten minutes. Finding a problem now beats finding it at hour one of the outage.
• Stage the kit in one place: station, cords, thermometers, lanterns, a printed contact list. Outages are dark; searching is expensive.

At the warning: 36 hours out#

A warning means storm conditions are expected. Final moves:

• Fridge and freezer to their coldest settings. Every degree colder is minutes of safe time later; put a thermometer inside each compartment.
• Top up the station to replace the test run’s draw.
• Set phones to low-power mode and park them on chargers until the grid drops.
• Get cash — card terminals and ATMs die with the grid, and the stores that reopen first after landfall are frequently cash-only for days.

During the outage: spend watt-hours like money#

The priority order from our outage guide applies verbatim: medical loads first, the fridge second, communications third, lights fourth, and nothing with a heating element — a 1,500 W kettle would empty a 1 kWh battery in about 34 minutes of use. Duty-cycle the fridge against its 4-hour unopened safe window (about two hours powered, one to two off) and leave the freezer closed entirely. Check the thermometers, not the door.

The one running load worth its cost: the router. Fifteen watts keeps outage maps, utility updates, and household comms alive — 360 Wh across a full day — for as long as your ISP’s node has power.

After landfall: the dangerous part#

More people die of carbon monoxide poisoning in the days after a hurricane than in most storms themselves — generators run around the clock, and someone pulls one into a garage out of the rain. The rules are absolute: outdoors, at least 20 feet from the house, exhaust away from every opening, never in a garage or under an awning. A battery station is the only backup power that belongs indoors; the safe division of labor between battery and generator is laid out in power station vs gas generator.

Then settle into the multi-day rhythm: panels out in clear weather, fridge on its duty cycle, station topped up from any live outlet you encounter — and log what actually drew power. Your own numbers, run through the sizing calculator, are next June’s shopping list.

The apartment version#

Renters and apartment dwellers run this checklist with one line deleted and one added. Deleted: everything about generators — there is nowhere legal or safe to run one on a balcony, and building codes agree. That makes the battery not one option among two but the entire plan, and it changes the sizing logic: with no recharge engine available, capacity and solar input are all you have, and a south-facing balcony or windowsill panel — even a 100 W folding one returning maybe 300–400 Wh on a clear day — is worth far more than it would be to a homeowner with a generator in the garage.

Added: the evacuation split. Apartment dwellers in surge zones are more likely to be told to leave, so weight portability when you buy — a 20-lb, 1 kWh-class unit rides out an evacuation in a trunk next to the go-bag, while a 60-lb unit effectively commits you to sheltering in place. Charge the unit, stage it by the door with its cables, and decide before the warning which scenario you’re equipping. The rest of the checklist — freezing water bottles, coldest fridge settings, low-power phones, cash — applies unchanged in any building.

Communications: the loads that punch above their weight#

Power planning during a hurricane is mostly about the fridge, but the loads that change outcomes are the small ones. The router draws about 15 W; keep it up as long as the ISP’s node survives, because outage maps, utility restoration estimates, and family check-ins all live behind it. When the node goes dark, phones fall back to cellular — set them to low-power mode and treat the power station’s USB ports as the household charging bar (a phone costs roughly 15 Wh per charge; even a nearly-spent 1 kWh unit holds dozens). A battery-powered or hand-crank NOAA weather radio belongs in the kit regardless: it’s the one receiver that works when both the ISP and the cell towers don’t, and it costs nothing from your watt-hour budget. Headlamps and lanterns beat phone flashlights for the same reason — they sip from their own batteries instead of draining the device you most need to keep alive.

When the grid comes back#

The checklist has a final stage that most kits skip, and it starts the moment the lights blink on:

1. Verify the fridge and freezer thermometers before restocking. If the fridge log shows more than 2 hours above 40°F, the perishables go — “when in doubt, throw it out” is the USDA’s phrasing, not ours.
2. Recharge everything to 100% — the station, USB banks, headlamps — before the post-storm restoration period ends. Grids often flicker for days after landfall, and the second outage arrives with your kit half-spent unless you refill during the gaps.
3. Write down what actually happened: how many watt-hours the outage consumed, which device you missed, which cable didn’t reach. Run the real numbers through the calculator while they’re fresh — that log is next season’s shopping list, and it’s how a kit gets better instead of just older.
4. Restock the consumables — batteries, shelf-stable food, the water you drank — while stores are calm again.

Then put the station back on its shelf, charged. Hurricane season runs to November 30, and the next named storm doesn’t care that you just used the kit.
