San Diego Wildfire Evacuation Routes & Alerts

Which alerts matter, what the terms mean, and the routes out of each high-risk corridor.

Last updated August 29, 2026

Quick answer

San Diego County issues wildfire evacuations through AlertSanDiego (register your cell and VoIP numbers — landlines are enrolled automatically), Wireless Emergency Alerts to any phone in the affected area, and the SD Emergency app, with live maps at sdcountyemergency.com. An evacuation warning means leave now if you need extra time; an evacuation order means leave immediately. In practice, the main routes out of San Diego's fire-prone corridors are I-15 and SR-78 from inland North County, SR-67 and I-8 from Ramona, Lakeside, and Alpine, SR-94 from the southeastern backcountry, and SR-76 from Fallbrook, Pala, and Valley Center — but any of them can close, so plan two routes in different directions from your home. Santa Ana wind events, typically September through December, are when fires move fastest; on red-flag days, keep your car above half a tank, park facing out, and have your go-bag loaded. Evacuation shelters open through the county and Red Cross, large-animal evacuation goes to sites like the Del Mar Fairgrounds, and most shelters accept pets in carriers or on leash.

Main evacuation corridors by region

Learn two routes out of your neighborhood — one toward the coast, one along a different highway. Fires close roads unpredictably.

Ramona, Poway, Lakeside

SR-67 south to I-8 is the primary route; SR-78 west toward Escondido is the alternate. Both jam quickly, so leave on warning, not order.

Alpine, Descanso, Pine Valley

I-8 west toward El Cajon is the main artery. When I-8 closes, options are limited — this is a corridor where leaving early matters most.

Fallbrook, Bonsall, Pala, Valley Center

SR-76 west to I-5 or east to I-15, plus Mission Road. Rural roads narrow fast; know which of your driveways connects through.

Escondido, San Marcos, Rancho Bernardo

I-15 and SR-78 are the backbone. The 2007 Witch Creek fire showed how quickly westbound lanes fill — stagger your departure early.

Jamul, Dulzura, Potrero

SR-94 west toward Spring Valley is essentially the only paved corridor. Backcountry residents should plan overnight bags kept in the car during Santa Ana events.

Julian and the mountains

SR-78 and SR-79 in multiple directions. Mountain fires can cut both; monitor which pass is open before choosing a direction.

Before fire season starts

Register for AlertSanDiego

Landlines are auto-enrolled; cell phones and VoIP are not. Add every family member's number and your work address.

Create defensible space

CAL FIRE requires 100 feet of defensible space where applicable — zone 1 within 30 feet cleared of dead fuel, zone 2 thinned and mowed.

Harden the house

Ember-resistant vents, gutter guards, and clearing leaves off the roof and out of gutters prevent the ember ignition that destroys most homes.

Photograph your belongings

A ten-minute video walkthrough of every room and open drawer makes an insurance claim dramatically easier.

Confirm your insurance

Many San Diego backcountry homeowners have been non-renewed. Know whether you're on the California FAIR Plan and what your extended replacement cost is.

Plan for animals

Horse owners should pre-arrange trailering. Del Mar Fairgrounds and other sites open for large animals during major fires.

Your go-bag and the five-minute list

Documents

Passports, birth certificates, insurance policies, deed or lease, and a USB or cloud copy of everything.

Medication and medical

A week of prescriptions, glasses, chargers for medical devices, and a written list of dosages.

N95 masks

Smoke exposure is the most common health impact for people far from the flames. Keep a box of N95s, not cloth masks.

Cash and chargers

Card readers fail during outages. Keep small bills, a power bank, and a car charger in the bag.

Pet kit

Carrier, leash, food, vaccination records, and a photo of you with your pet in case you're separated.

Comfort items for kids

One familiar toy or blanket per child. Evacuations are long and shelters are loud.

During and after an evacuation

Leave on the warning

The people who get trapped are almost always the ones who waited for the order. Traffic is the real danger, not the flame front.

Don't rely on one app

Cross-check the county map, CAL FIRE incident page, and your local scanner or news feed. Social media rumors move faster than facts.

Air quality after the fire

Smoke persists for days. Check AQI, run HVAC on recirculate with a MERV 13 filter, and keep a box-fan filter in a bedroom.

Don't return until it's lifted

Downed lines, hot spots, and blocked roads make early returns dangerous and slow the crews still working.

Document damage before cleanup

Photograph everything before moving debris. Contact your insurer the same day and start a claim log with names and times.

How to use this page

• This is a planning reference, not a live emergency feed. During an active incident, follow instructions from CAL FIRE, San Diego County Emergency Services, and your local fire department.
• Register for AlertSanDiego and add SD Emergency to your phone before you need them — signing up mid-evacuation is too late.
• Conditions, schedules, and closures change every year. Confirm event times and beach status with official sources the week of.
• Nothing here is legal, medical, or insurance advice. When in doubt about water quality or air quality, stay out and stay in.

Frequently asked

How do I get wildfire evacuation alerts in San Diego?

Register at AlertSanDiego for county phone, text, and email notifications, install the SD Emergency app, and keep Wireless Emergency Alerts enabled on your phone. Live maps are posted at sdcountyemergency.com.

What's the difference between an evacuation warning and an order?

A warning means the threat is possible and you should leave now if you need extra time or have animals. An order means leave immediately — do not stop to pack more.

Which highways are the main evacuation routes?

I-15 and SR-78 for inland North County, SR-67 and I-8 for Ramona, Lakeside, and Alpine, SR-76 for Fallbrook and Valley Center, and SR-94 for the southeastern backcountry. Always plan a second route.

When is San Diego's wildfire season?

Risk is year-round, but the most dangerous window is September through December, when Santa Ana winds combine with the driest fuel of the year.

Where do evacuation shelters open?

The county and Red Cross open shelters at schools, community centers, and recreation centers depending on the fire. Locations are posted on the SD Emergency app and county emergency site.

Can I bring pets to a shelter?

Most county shelters accept pets in carriers or on leash, and county animal services opens co-located animal shelters. Large animals go to designated sites such as the Del Mar Fairgrounds.

What should I do on a red flag day?

Keep your gas tank above half, park facing out, load the go-bag, charge devices, and avoid any activity that throws sparks — mowing dry grass or dragging trailer chains starts fires.
