Preparing a generator for a hurricane comes down to readiness checks, safe placement, fuel storage and safe connection, finished before the storm forms. The Atlantic season runs June 1 through November 30, so the work belongs in the weeks before the first named storm.

The machine you own shapes every step. A portable unit needs hands-on fuel and a spot outdoors, while a standby unit needs scheduled checks and a reliable fuel line. Size matters too, because a generator that can’t start your refrigerator is just noise.

Most storm-season failures trace back to a few things: stale fuel, a unit that hasn’t run in months, or a setup too close to the house. Outages after a hurricane can last for days, and carbon monoxide kills people who run generators in the wrong place.

Run the engine and check your fuel before the first storm of the season shows up on the forecast.

What Does Generator Hurricane Preparation Involve?

Generator hurricane preparation covers readiness checks, placement, fuel storage and safe connection, so the unit keeps running through an outage that can last for days. Each piece fails in its own way, and one weak link ends the whole plan.

Readiness means the engine starts and runs under load. Placement keeps exhaust out of the house and the machine out of water. Fuel storage decides how long you can actually run, and safe connection keeps your household and utility crews out of danger.

The Atlantic hurricane season runs from June 1 through November 30, which gives you months to get this done calmly. If you don’t own a unit yet, read how to choose a generator before the season gets busy.

Which Generator Setup Fits a Hurricane Outage?

The right setup comes down to portable or standby type and wattage for your essential loads. Get those two right and every later step fits the machine you actually have.

Portable or Standby: Which Handles a Storm Better?

A standby generator wins on hands-off operation and fuel supply, while a portable generator wins on flexibility and lower upfront cost. Storm exposure and run time separate them most.

A standby unit sits outside, starts automatically and usually draws from a natural gas line or a large propane tank. You don’t refuel it mid-storm. That convenience comes with a permanent install, and the unit can’t move out of a surge zone.

A portable unit runs on gasoline or propane that you haul and pour yourself. You can place it exactly where you want it. You can also stash it indoors, safely away from the weather, until it’s needed.

The tradeoff is effort. Portable units need refueling through the night and a dry, open spot for each run. Broad costs differ too, and how much does a generator cost depends mostly on this choice, with standby systems sitting well above portables once installation is counted.

What Size Generator Covers Your Essentials?

Generator size is set by your essential appliances, and the starting load of motor-driven items matters more than their running load. A refrigerator, well pump or air conditioner pulls a surge when its motor kicks on.

List what you truly need during an outage: refrigeration, a well pump if you have one, some cooling, and any medical devices. Those loads drive the wattage, not the whole house.

Running watts keep things going, but starting watts decide whether the machine can start a compressor at all. An undersized unit will bog down or trip when a motor surges.

Size for the heaviest motor starting while other essentials already run. Then leave headroom. For the full math, see how to size a generator, and consider a modest step up in size if you expect to add loads later.

How Do You Get a Generator Ready Before Hurricane Season?

Readiness comes down to portable generator checks and standby generator check intervals. Each type needs its own routine.

What Should You Check on a Portable Generator?

A portable generator needs a test run, then a look at oil, air filter, spark plug and fuel. Do it well before a storm, not the night before.

Start the engine and let it run under a modest load. Listen for surging or stalling. Check the oil level and condition, and replace it if it looks dark or gritty. Inspect the air filter for dirt, and pull the spark plug to look for heavy deposits or wear.

Fuel is the usual culprit. Gasoline that sat all winter can gum up the carburetor. If the unit sputters, drain the old fuel and refill with fresh. If a unit refuses to turn over at all, the guide on why a generator won’t start covers the common causes. Hmm

Preparing a generator for a hurricane comes down to readiness checks, safe placement, fuel storage and safe connection, all finished before a storm forms. The Atlantic season runs June 1 through November 30, so the work belongs in the weeks before the first named storm.

The machine you own shapes every step. A portable unit needs hands-on fuel and a dry spot outdoors, while a standby unit needs scheduled checks and a dependable fuel line. Size matters too, because a generator that can’t start your refrigerator is just noise.

Most storm-season failures trace back to stale fuel, a unit that hasn’t run in months, or a setup too close to the house. Outages after a hurricane can last for days, and carbon monoxide is the hazard that hurts people.

Run the engine and check your fuel before the first storm shows up on the forecast.

Portable or Standby: Which Handles a Storm Better?

A standby generator wins on hands-off fuel supply and automatic starting, while a portable generator wins on flexibility and lower upfront cost. Storm exposure and effort separate them most.

A standby unit sits outside, starts on its own and usually draws from a natural gas line or a large propane tank. You don’t refuel it at 2 a.m. The tradeoff is a permanent install that can’t move out of a flood-prone spot.

A portable unit runs on gasoline or propane that you haul and pour yourself. You choose where it sits, and you can store it somewhere dry until needed. The cost is effort: refueling through the night and setting it up in the weather.

Broad cost gaps follow the same split. How much does a generator cost depends mostly on this choice, with standby systems sitting well above portables once installation is counted.

How Do You Get a Generator Ready Before Hurricane Season?

Readiness comes down to portable generator checks and standby generator check intervals. Each type needs its own routine.

What Should You Check on a Portable Generator?

A portable generator needs a test run plus a look at oil, air filter, spark plug and fuel. Do it well before a storm, not the night before.

Start the engine and run it under a modest load. Listen for surging or stalling. Check the oil level and color, and change it if it looks dark or gritty. Inspect the air filter for dirt and pull the spark plug to look for heavy deposits or wear.

Fuel is the usual culprit. Gasoline that sat all winter can gum up the carburetor. If the engine won’t turn over or dies right away, the causes behind a generator won’t start are worth working through before a storm, not during one.

Finish by checking cords and outlets for cracked insulation or bent prongs. Replace anything damaged.

How Often Should a Standby Generator Be Checked?

A standby generator should get a basic operational check about every two weeks (bi-weekly) where practical, plus a professional service visit before the season. That biweekly pace is the commercial standard, and homeowners can borrow the idea.

Most standby units run an automatic exercise cycle on a set schedule. Watch that it actually completes. Look for warning lights, fluid leaks and a clear area around the enclosure.

A service visit makes sense if the unit has gone a full year without one, if it threw a fault code, or if you recently changed your electrical load. A technician can test the transfer switch and the battery, which owners often can’t do themselves.

Where Should You Place a Generator During a Hurricane?

Placement comes down to distance from the house, shelter from rain and wind, and protection from flooding. A generator must sit outdoors, dry and clear of openings.

How Far Should a Generator Sit From Your Home?

Keep a generator at least 20 feet from your home, with the exhaust pointed away from windows, doors and vents. Carbon monoxide is odorless and can drift indoors faster than most people expect.

Local government guidance on distance varies from source to source. Go with the more cautious number. The U.S. Consumer Product Safety Commission also warns that a generator should never run in a garage, basement or crawlspace, even with a door open.

A battery-backed CO alarm indoors still matters. Distance lowers the risk but doesn’t remove it, especially when wind pushes exhaust toward the house. Put alarms near sleeping areas and test them before the season starts.

If your manual asks for more clearance than 20 feet, follow the manual.

How Do You Shelter a Generator From Rain and Wind?

Shelter a running generator with a purpose-built generator tent or open-sided canopy that keeps rain off while letting exhaust move freely. Never enclose the unit.

Water on a running generator creates shock risk and can damage the alternator. Wind-driven rain is the real threat in a hurricane, so the cover needs a solid anchor and a roof pitched to shed water.

Keep the sides open, or use a design with big vents, so heat and exhaust escape. A GenTent or a similar product is built for that job. A plastic tarp thrown over the unit is not.

Place the cover downwind of the house when possible, so exhaust travels away from living space.

How Do You Protect a Generator From Flooding?

Protect a generator from floods by raising it off the ground and choosing a spot that sheds water rather than collecting it. Floodwater ruins engines and electrical parts fast.

An elevated pad, such as a sturdy platform or concrete slab, keeps the unit above splashing and shallow standing water. Avoid low corners of the yard and spots below downspouts.

If surge or rising water is forecast, don’t run the unit at all in those conditions. Move a portable model to higher ground, and shut off a standby unit if water nears it. Water and electricity never mix, and a flooded generator needs inspection before it runs again.

How Should You Store Fuel for a Hurricane Generator?

Fuel planning comes down to which fuel to rely on, how much to keep and for how long, and where to store it safely. Fuel supply is the most common failure point in long outages.

Which Fuel Is Easiest to Get After a Storm?

Natural gas and propane are usually easiest to keep going, while gasoline and diesel depend on stations that may be closed or out of power. No fuel is always available after a hurricane.

Natural gas needs no refueling but depends on the utility line staying intact. Propane stores for a long time in tanks and doesn’t go stale. Gasoline is easy to find until demand spikes, then lines form and pumps stall without power. Diesel stores better than gasoline but still needs a supplier.

If you rely on diesel, line up a backup supplier 50 to 100 miles away, so one regional event doesn’t cut off both. Pick the fuel your unit actually burns, and plan around its weak spot.

How Much Fuel Should You Store, and for How Long?

Store enough fuel to cover your expected run time at your actual load, and keep it fresh with stabilizer and rotation. A bigger stockpile only helps if it still burns cleanly.

Run time depends on load. A generator carrying only a refrigerator and a few lights uses far less than one pushing an air conditioner. To estimate, see how much gas will your generator use at different loads, and check how long can a generator run on a full tank for your model.

Gasoline degrades over months and varnishes fuel systems. Diesel lasts longer but can still grow contaminated. Add stabilizer when you fill containers, and use older fuel in the lawn mower before refilling.

Rotate stock before the season so the fuel you’re counting on is fresh.

Where Is It Safe to Keep Stored Fuel?

Keep fuel in approved containers, away from living space and ignition sources, and never in the area where the generator runs. Fuel vapors catch fire easily.

Use containers made for fuel, with tight caps and proper labeling. A detached shed or a ventilated spot away from the house works better than an attached garage with a water heater pilot light.

Keep storage well apart from the generator, since a hot engine and spilled gasoline are a bad pairing. Don’t store fuel near furnaces, grills or anything that sparks.

Check containers for leaks before the season, and replace any that are cracked or swollen.

How Do You Connect a Generator to Your Home Safely?

The safe route is a transfer switch or interlock, while heavy-duty extension cords work for a few essentials. Improvised connections put your household and utility workers at risk.

What Does a Transfer Switch or Interlock Do?

A transfer switch or interlock isolates your house from the grid so generator power can’t flow back out onto utility lines. That reverse flow, called backfeeding, can kill line crews.

An automatic transfer switch handles the changeover on its own, which fits standby systems. An interlock kit lets you feed a panel from a portable unit while physically blocking the main breaker. Both prevent the dangerous setup of plugging a generator into a wall outlet.

Hire a licensed electrician for the install. A mistake can start fires or energize lines you think are dead. The process is covered in how to install a generator transfer switch, but it isn’t a casual weekend job.

When Are Heavy-Duty Extension Cords Enough?

Outdoor-rated, heavy-duty extension cords are enough when you only need to run a few essential appliances, like a refrigerator and a lamp. Beyond that, cords get clumsy.

Choose cords rated for outdoor use and thick enough for the load. Check them for cracks, exposed wire and bent prongs before use, and keep them out of standing water. Run them through a slightly open window, not under a closed door.

This approach stops working once you want lights, a furnace blower or a well pump across the house. At that point, how to power house with generator through a transfer switch or interlock is the better route.

Is It Safe to Run a Generator During a Storm?

Yes, a generator is safe in a storm if it runs outdoors, stays dry, and sits well away from openings. The hazards split into carbon monoxide poisoning and shock or fire.

How Do You Prevent Carbon Monoxide Poisoning?

Prevent carbon monoxide poisoning by never running a generator in a garage, basement or near any opening, and by keeping battery-backed CO alarms indoors. Carbon monoxide has no smell, and it builds up quietly.

Alarms with battery backup keep working when power fails, which protects sleeping households. Place one on each level and near bedrooms. Test them before the season.

Know the symptoms: headache, dizziness, nausea, confusion and weakness. If anyone feels them, get outside into fresh air right away, then call emergency services. Don’t stay to find the source.

Keep the generator outdoors even if it’s raining hard. Bring in the shelter, not the machine.

How Do You Avoid Shock and Fire Hazards?

Avoid shock and fire by keeping the unit and cords dry, grounding the generator as the manual directs, and letting the engine cool before refueling. Fuel poured on a hot engine can ignite.

Never touch a wet generator or cord with wet hands. Check that cords aren’t pinched or running through puddles. Follow the grounding instructions in your manual, since the right method varies by model.

Shut the engine off and wait before adding fuel. Handle fuel away from the running machine and from anyone smoking. For a step-by-step on safe operation, see how to use a generator.

How Do You Prepare for 72 Hours Without Power?

A 72-hour plan needs a stocked supply kit and a short list of final tasks before landfall. The generator supports the plan but doesn’t replace it.

What Goes in a Hurricane Supply Kit?

A hurricane kit should hold at least one gallon of water per person per day for 7 days, 7 days of easy-to-eat food, and a 7-day supply of all medications. Add lighting, spare batteries and important documents.

FEMA and Ready.gov both build their kits around these basics. Pick food that needs no cooking, since the stove may be out. Keep flashlights and extra batteries where you can find them in the dark.

Store documents like insurance papers and IDs in a waterproof bag. If you rely on a generator for refrigeration or medical devices, have a backup plan in case it fails.

What Should You Finish Before the Storm Arrives?

Finish by watching the forecast, filling fuel containers, setting up the generator spot, and confirming alarms and cords. The timing runs in stages.

Start watching weather updates about 72 hours out, and follow the National Hurricane Center for track changes. Around 48 hours before, bring in outdoor items the wind could throw. By 24 hours before, finish home prep if you’re staying.

Fill fuel containers early, since lines get long. Place the generator and its shelter, test CO alarms, and inspect cords once more.

A generator that ran flawlessly for the first two days can quietly start to fail on the fourth, and by then the storm is gone but the outage isn’t. Oil breaks down, filters clog and fuel residue builds up after days of nonstop running. What do you check first when the lights finally return?

What Should You Do With a Generator After the Storm?

After the storm, inspect the oil, air filter and fuel system before storing the unit, and have any generator that took on floodwater inspected before it runs again. Long continuous running wears an engine in ways light use doesn’t.

A healthy unit shows clean, amber oil, a lightly dusty filter and no fuel odor from leaks. A worn unit shows dark or sludgy oil, a clogged filter and varnish or residue where fuel has sat. Change the oil and filter, and drain leftover gasoline you don’t plan to use soon.

Flooding changes the picture. Water in the engine, alternator or outlets can cause shorts, corrosion and shock. Don’t start a flooded generator to see if it works. Have a qualified technician check it first.

Store it dry and ready, then plan the next refill before the next season.

Do Local Rules Affect How You Can Use a Generator?

Yes, local permits and ordinances can apply to generator installation, fuel storage and noise. Rules differ by city, county and homeowners association.

Standby installations commonly need permits, and fuel storage limits may apply to how much you can keep and where. Noise rules matter too, especially in dense neighborhoods. Building codes may also govern how a transfer switch is wired.

Call your local building office before the season starts, not during a storm. A quick check avoids fines, failed inspections and surprises at resale. Ask about your HOA as well, since some restrict visible equipment.

Do Inverter Generators Make Sense for Storm Outages?

Inverter generators make sense when you need clean power for electronics, quiet running near neighbors, and better fuel economy. A conventional portable unit is often more practical for heavy loads.

Inverter models produce stable power that protects laptops, phones and modern appliances. They run quieter and can adjust engine speed to the load, which stretches fuel. If you want to know how does an inverter generator work, the short version is that it converts and smooths its output electronically.

Conventional portables usually deliver more raw power for the money, which matters if you need to start a well pump or air conditioner. Choose an inverter for light, sensitive loads and a conventional unit for heavy motor-driven ones.

Generator Hurricane Preparation FAQs

What is the 80% rule for generators?
The 80% rule says to keep your total load at or below 80% of the generator’s rated running output. That headroom reduces strain and heat during long runs, and it leaves room for startup surges from motors. If your essentials push past it, trim the load or step up a size.

What is the 20/20 rule for generators?
It’s informal shorthand rather than a formal standard, and versions vary. The most common use is distance: keep the generator about 20 feet from the house with exhaust pointed away from windows, doors and vents. Follow your manual if it asks for more, and keep a battery-backed CO alarm indoors.

Can you run a generator in a garage or on a covered porch?
No. Garages, even with the door open, and covered porches trap carbon monoxide that drifts toward windows and doors. Run the unit outdoors, well away from the house, under a purpose-built canopy or open-sided cover that lets exhaust escape freely. Never fully enclose it.

How early should you start preparing a generator for a hurricane?
Start before the season opens on June 1, with test runs, fresh fuel and basic checks. Once a storm forms, begin watching forecasts about 72 hours out, bring loose outdoor items inside around 48 hours, and finish home preparations by 24 hours before landfall.
