The Hurricane Power Prep Guide (Gulf Coast Edition)

This is the companion to our Texas storm prep guide, which covers both of Texas's outage seasons. This page is narrower on purpose: it's the hurricane-specific plan, sized for the outage hurricanes actually cause — not an overnight blip, but days, sometimes more than a week, of no grid at all. The design case is Hurricane Beryl: a storm that weakened to a tropical storm before it even made landfall near Houston on July 8, 2024, and still left nearly 3 million people without power, with tens of thousands still dark more than a week later. A "minor" hurricane produced a major outage — that gap between storm category and outage length is what this guide plans around.

Size for a week, not a night

The single biggest mistake in hurricane power prep is sizing backup for the storm's landfall day instead of the outage that follows it. Beryl's own numbers make the case: roughly 226,000 CenterPoint Energy customers were still without power eight days after landfall, and some restorations ran past July 19 — eleven days out. If your plan tops off one battery and calls it done, you're prepared for the wind, not the outage. Multi-day capacity, a plan to recharge from a car or generator once the battery runs down, and a realistic accounting of what actually needs power for a week (not everything) are the three pieces an overnight-outage plan is missing.

The charge-everything trigger

Don't wait for a hurricane warning. NOAA's own climatology shows the Atlantic season's real center of mass is mid-August through mid-October, peaking around September 10 — but Gulf systems have organized and struck fast outside that window too, sometimes with only a few days' notice between formation and landfall. The moment a system enters the Gulf with your area in the forecast cone, that's the trigger: every power station to 100%, phones and battery banks topped off, the fridge and freezer set to their coldest and packed for thermal mass, the car's tank filled. Waiting for landfall to be certain is waiting for the shipping delays, sold-out shelves, and gas-station lines that show up in the same 72 hours everyone else has the same idea.

During: the 4-hour fridge clock is real

The CDC's numbers are blunt: a closed refrigerator holds a safe temperature for about 4 hours without power, a full freezer for about 48. That's not a suggestion to plan around loosely — it's the actual clock a multi-day hurricane outage puts you on, and it's exactly why this site treats fridge backup as a baseline load, not a luxury. If your battery capacity covers the fridge continuously through the outage, you've beaten that clock entirely instead of racing it. Beyond the fridge: CPAP with the humidifier off, lights on LED lanterns instead of ceiling fixtures, and — the rule that doesn't bend — any combustion generator runs outside only, at least 20 feet from the house, exhaust pointed away, and elevated above whatever storm surge or street flooding the forecast mentions. CPSC counts roughly 85 CO deaths a year from portable generators, and a flooded yard during a hurricane is precisely the scenario that turns "ventilated enough" into a fatal miscalculation. A battery station has no exhaust and nothing that flooding disables.

After: recharge before the next system

Hurricane season doesn't stop after one storm passes — refill every battery within the first day power is back, because the same Gulf that produced this system can produce another one before it ends November 30. If Beryl-scale duration exposed a real capacity gap — you ran out before the grid came back, or you were rationing watts you needed for something that mattered — that's the evidence for your next purchase, not a guess. The ranked picks are sorted by exactly that kind of real-world capacity math, and if the load that broke your plan was something a small unit can't run at all — a window AC, a well pump — whole-house-adjacent capacity is the next page to read.
