Wildfire Season Just Got Worse. Here's How to Prepare Your Home

After two relatively mild fire seasons, 2024 looks poised to reverse that trend.

As of early July, Cal Fire has responded to more than 3,500 wildland fires that have burned more than 207,000 acres. That’s a similar number of fires but 197,000 more acres than at this time in 2023.

Punishingly hot and dry conditions around the state have dried out grasses and brush, laying the conditions for fast-moving intense wildfires.

“We are fully fuel loaded at this point,” said Brian Garcia, the National Weather Service’s warning coordination meteorologist, on KQED’s Forum recently. He’s most concerned about the fall, when the Bay Area typically has its largest fires.

That’s when “[the weather] turns into the low humidity offshore wind, the gusty offshore wind regime that brought us fires like the Nuns, the Tubbs, the Kincade, the Camp,” said Garcia, citing some of the most destructive fires in California history, and in the history of the nation. “We need to be prepared now.”

Cal Fire Battalion Chief of Communications Issac Sanchez said Californians shouldn’t wait. “Preparation steps need to be done now. That way, when a fire breaks out — not if a fire breaks out in your community, but when a fire breaks out in your community — you’re ready to react at a moment’s notice.”

“The public needs to maintain a constant state of readiness,” he said.

Cal Fire has launched some new tools to help residents get organized. Its firePLANNER application hosts to-do checklists tailored to the user’s circumstances to prioritize safety steps. It also offers text alerts and information to track wildfires.

In any disaster, there aren’t enough emergency personnel to help everyone. So first responders depend on the majority of people being ready and able to take care of themselves and help their neighbors.

One of the top things to do, said Sanchez, is a self-assessment of the trees, brush and other vegetation on and around your property. Learn the steps to protect your home from wildfire and start clearing brush and doing other key tasks now.

Cal Fire’s Ready for Wildfire website and app breaks down steps everyone can take to get prepared. Sanchez also advised people to register for emergency alerts and evacuation warnings from their county’s emergency services agencies.

Preparing for a wildfire or other disaster can feel daunting. So the Listos California Emergency Preparedness Campaign provides a five-step readiness plan that sends you reminders via text.

Here are some guidelines to help get you ready.

Prepare the outside of your home

If you live in a fire-prone area, sometimes called the “wildland-urban interface,” clearing brush and tree limbs close to your home is an important way to slow the spread of fires, increasing the chance of your home’s survival. This area of cleared and low vegetation is called “defensible space,” and you can think of it as a buffer zone, free of anything likely to catch fire.

Cal Fire asks homeowners to think about two zones of defensible space. The first extends 30 feet from homes, outbuildings and decks:

• Remove overhanging and dead branches. All branches should be a minimum of 10 feet away from your chimney and other trees.
• All dead vegetation should be removed.
• Clear dry leaves and pine needles from the yard, roof and rain gutters.
• Move wood piles to Zone 2.

Zone 2 extends from the end of Zone 1 to 100 feet out from your home, structures and deck:

• Here, mow annual grasses down to 4 inches or less, and create horizontal and vertical spaces between vegetation.
• Don’t let fallen leaves, needles, twigs, bark, cones and small branches accumulate more than 3 inches high.

One thing people don’t think about a lot is to make sure their home address is clearly visible. You should make sure it is. That way, if you call for emergency help, responders can find you.

‘Harden’ your home against wildfire

Many homes that burn in a wildfire are never in the path of flames, but ignite from flying embers and firebrands that can accumulate in eaves or drift into vents. Hardening homes against fire can be as inexpensive as installing screens over vents and as pricey as installing new windows, roofing or siding.

Have a go bag ready

There are three reasons people tend to put off preparing for a disaster, says Karen Baker, co-chair of Listos California. “They either find it scary, expensive, and/or time-consuming,” she said.

Listos tries to overcome those qualms with a simple readiness guide, available in English (PDF) and Spanish (PDF). Sign up for readiness text prompts here.

The organization recommends packing up some items in advance so you can get out of the house quickly if you need to. If cost is a concern, you can assemble the kits over time. Recommended items to pack beforehand:

• Documents: copies of insurance, identification, and other important papers and photos.
• Cash: $1 and $5 bills are best.
• Map: with different routes out of your neighborhood marked.
• Medications list: Include all prescriptions and other important medical information.
• Portable radio.
• Flashlight.

To grab on your way out the door:

• Wallet, purse, keys.
• Phone and charger.
• Medicine.
• Portable computer.
• First-aid supplies, N95 masks, hand sanitizer, wipes.
• Change of clothes.
• Anything else needed by people or animals in your household.

Create a plan for your household in the event of a wildfire emergency. (See Cal Fire’s wildfire action plan checklist.) And be sure you’re signed up to receive emergency alerts for your area. You can sign up here.

Cal Fire also recommends mapping out your household’s fire escape route and running your own fire drills (PDF).

Expect Smoky Days

With wildfire comes smoke.

You can get smoke advisories, forecasts and current fire conditions through the federal government’s AirNow website.

How to protect yourself from wildfire smoke:

• Keep windows and doors closed.
• Use fans, air conditioners, ice packs or a frozen bandana to stay cool.
• Know how the ventilation system in your home works and close the outdoor air damper, if there is one.
• Avoid making indoor air pollution any worse by smoking cigarettes, spraying aerosols, frying food or burning candles or incense.
• Buy an air cleaner (also called an air purifier) that doesn’t produce ozone and has a HEPA filter. Designate a “clean-air room” in your home for smoky days. (The Environmental Protection Agency has a guide (PDF) for air cleaners in the home).
• If air purifiers are too costly, here’s a less expensive DIY option.

Air purifiers can range from $100 on up and can be hard to obtain during bad fires, so think about buying one in advance of fire season. In California, few resources exist to help people with low income afford these devices; one asthma intervention program in Fresno does provide enrollees with air cleaners for a year. In years past, some counties have set up “clean air shelters” during smoky days.

People power

One theme running through the advice of fire and emergency officials: Your social network is one of your most important safety tools.

“Really, when it comes down to a ‘no-notice’ event, like a fast-running wildland fire through your neighborhood, it really is neighbor helping neighbor,“ said Santa Rosa Fire Chief Gossner.

That means it’s time to think about who in your neighborhood might need help getting ready for fire season. Maybe they’re elderly and could use some help trimming vegetation. During an evacuation order, who will you check on and who will check on you? Write down their names and contact information, pack the list in your go bag, and share it with others for backup. At least one person on your list should live outside your area to ensure you’re not relying on someone who also might be affected by the fire.

Even if this feels overwhelming or scary, the time to do it is now. Every step you can take toward preparedness makes you, your family, and your community a little bit safer.
