Can You Use a Generator in a Storm or Hurricane?

You can use a generator during a storm or hurricane—but only if you take serious precautions. Using one in the middle of a downpour or high winds without protection is a recipe for electrocution, fire hazards, or a ruined generator.

If you’ve lost power during severe weather and are reaching for the pull cord, here’s exactly what to do to stay safe.

🛑 Never Run a Generator Exposed in the Rain

Generators and water don’t mix—period. Moisture can get into the outlets and wiring, which can cause:

• Severe electrical shock
• Irreversible generator damage
• Short circuits and fire risk

Even worse, many portable generators are grounded to the frame. That means the outer metal parts can become live if there’s water involved. And yes, I’ve seen what happens when someone tries to unplug something with wet hands. Don’t be that guy.

✅ How to Use a Generator Safely During a Storm

1. Keep It Covered (But Ventilated)

You absolutely need to protect your generator from rain and windblown debris. A quality generator cover or weather-rated canopy is a must. I personally prefer covers like this one that are designed to keep outlets dry while allowing airflow.

Avoid sealing it too tightly—generators need ventilation or they’ll overheat or trap exhaust. If you’re handy, you can also build your own DIY enclosure with proper venting.

2. Place It on High, Dry Ground

Storms often come with flooding. Make sure your generator is placed on level, elevated ground—not the lowest point in the yard. Keep it away from puddles, mud, and any runoff areas.

Pro tip: Don’t park it on the driveway where rain pools. Learned that the hard way.

3. Anchor It Down (Seriously)

High winds can do more than knock over patio furniture. Hurricanes can pick up loose equipment and turn it into airborne battering rams. Use bungee cords or brackets to anchor your generator, especially if it’s under a lightweight canopy or tent.

If your area is actively under a hurricane warning, wait until winds die down before setting up. Running around in 70 mph gusts with a gas can and a socket wrench is a good way to get on the evening news—for the wrong reason.

⚠️ Avoid These Common Mistakes

• Running it indoors or in a garage: Carbon monoxide is a silent killer. Even with the door open, it can pool and drift indoors. Keep your generator at least 20 feet from your house.
• Using it without a transfer switch: Backfeeding can electrocute utility workers. A proper power transfer system is not only safer—it’s more efficient.
• Waiting too long to set up: If you know a storm is coming, get your generator ready ahead of time. Once it’s raining sideways, you’re already behind the curve.

Final Thoughts

Yes, you can use a generator during storms—but only with a proper cover, dry placement, and common sense.

Don’t gamble with safety just to get your coffee maker running. Anchor the generator down, keep it ventilated, and never run it exposed to the elements. If you’re prepped ahead of time, you’ll be back online while your neighbors are still fumbling with wet extension cords.

Stay safe—and don’t forget the fuel stabilizer.
