How Do I Prepare for Hurricane-Season Power Outages?
June through November, Gulf Coast homes plan around CenterPoint and TNMP outages. A practical preparedness checklist: before the season, when a storm enters the Gulf, during the outage, and at restoration.
Outage preparedness is a calendar, not a shopping trip: set up your home's backup plan before June, execute a short checklist when a storm enters the Gulf, run safe during the outage, and protect your equipment at restoration. Between hurricane season, tropical downpours, and the occasional freeze, extended outages are a when-not-if reality on CenterPoint and TNMP territory. The households that ride outages out comfortably made their decisions in March, not in the cone of uncertainty.
What should be done before hurricane season starts?
- Decide your power plan: standby generator (automatic, whole-home capable — see sizing), portable generator (cheaper, manual, fuel-hungry), or evacuation-and-endure. Any of the three works; choosing none of them by default is the plan that fails.
- Service what you have: generator annual service, fresh battery, transfer-switch test. The generators that fail in storms are overwhelmingly the unserviced ones.
- Add surge protection: restoration surges damage more electronics than outages do — see whole-home surge protection.
- Register for alerts with your utility's outage tracker and your county's emergency notifications.
What's the checklist when a storm enters the Gulf?
Top off fuel — propane tanks, gasoline cans (stored safely, treated with stabilizer), the car. Test-run a portable generator now, not by flashlight later. Pre-cool the house a couple of degrees and freeze water bottles to pack refrigerator and freezer thermal mass. Charge everything, stage flashlights and battery fans, and photograph your electrical panel and equipment nameplates — genuinely useful for insurance and for whoever services things later. If anyone in the home is medically dependent on power, register with the utility's critical-care program and have a non-negotiable evacuation trigger.
How do we run safely during the outage itself?
The non-negotiable: portable generators run outdoors only — 20+ feet from the house, exhaust pointed away from windows, never in a garage even with the door open. Carbon monoxide from generators kills more people in hurricane aftermaths than the storms themselves. Feed appliances with heavy-gauge outdoor-rated cords, or better, through a professionally installed transfer switch or inlet. Keep refrigerator doors closed (roughly 4 hours of safe cold unopened; a packed freezer holds 24–48). Run the generator in blocks — cool the house, chill the fridge, rest the unit — to stretch fuel.
What should I do when power comes back?
Restoration is a surge event. If you don't have whole-home surge protection, switch off sensitive equipment — including the AC at the thermostat — when the outage starts, and bring things back in stages once power holds steady. Give the grid a few minutes before restarting central AC (some utilities' first minutes are shaky), and if the AC won't start or trips after restoration, stop and call rather than resetting repeatedly — compressors damaged by brownout voltage fail on the retry. Standby owners: glance at the unit's status lights and log the runtime; an outage is effectively unscheduled engine hours, and service intervals count them.
Quick answers
How long do outages actually last here?
Routine storm outages: hours. A direct hurricane hit: days to weeks in the hardest-hit areas — Ike in 2008 left parts of this region dark for over two weeks. Plan for days; be glad when it's hours.
Should I turn off my AC during an outage?
Yes, at the thermostat — it protects the compressor from restoration surges and brownout restarts, and prevents everything in the house from slamming on at once when power returns.
Is a portable generator enough for a Gulf Coast summer outage?
It keeps food cold and fans running, which is survival, not comfort — most portables can't start central AC. If sleeping in August heat is the concern, that's the standby-generator conversation.
