California Wildfire Alerts: How to Sign Up for Emergency Notifications in Your County
Every second counts when a wildfire is moving fast. In California, where fires can spread at the speed of a running horse in dry, wind-driven conditions, getting an evacuation alert five minutes earlier can make the difference between a safe exit and a dangerous one. Yet millions of California homeowners still rely on a neighbor's phone call — or worse, the smell of smoke — as their first warning.
The good news: California has a layered system of wildfire alert and notification tools available to every resident, most of them free. The challenge is that no single statewide system covers everyone. Each county manages its own emergency notification platform, which means the steps to sign up vary depending on where you live.
This guide walks you through every layer of California's wildfire alert system — from automatic phone alerts to app-based notifications — and tells you exactly how to get signed up before fire season arrives.
Key Takeaways
- California has no single statewide alert system — you need to sign up with your specific county's platform to receive evacuation orders and warnings.
- Wireless Emergency Alerts (WEA) reach most phones automatically, but they are a last resort — county systems are faster and more targeted.
- Most county sign-ups are free and take less than five minutes at your county's Office of Emergency Services website.
- Register every address that matters to you — your home, your workplace, your children's school, and aging parents' homes.
- Download the Watch Duty app for statewide fire incident monitoring, even if you already have your county's alerts.
- Don't wait — sign up before fire season, not during it when systems may be overwhelmed.
Layer 1: Wireless Emergency Alerts — The Baseline You Already Have
Wireless Emergency Alerts are government-issued text-like messages sent directly to all WEA-capable mobile phones in a geographic area — no sign-up required. If you've ever had your phone buzz loudly with an amber alert or an extreme weather warning, you've experienced a WEA.
During major wildfire events, local authorities can issue WEAs for evacuation orders and warnings. These alerts are geographically targeted to the affected area, meaning only phones physically present in that zone receive the message.
Make sure WEA is enabled on your phone. On iPhones, go to Settings, then Notifications, then Government Alerts and ensure Emergency Alerts is toggled on. On Android, the path varies by manufacturer but look under Settings, Apps, and Emergency Alerts.
Important caveat: WEA is a safety net, not a primary notification system. It activates only when an official evacuation order or warning has already been issued. County-level systems deliver more precise, earlier notifications — sometimes before an evacuation order is formally declared.
Layer 2: Your County's Emergency Alert System
Each California county operates its own mass notification platform, typically through vendors like Everbridge, Rave Mobile Safety, or Genasys (formerly Zonehaven). These systems send targeted alerts by phone call, text message, and email to residents who have registered — and they can reach you faster and with more detail than WEA.
California's Office of Emergency Services maintains a county-by-county sign-up directory at calalerts.org. Visit the site, find your county in the list, click through to your county's registration page, enter your contact information, and select all notification methods (call, text, and email).
Los Angeles County — NotifyLA
LA County uses NotifyLA at ready.lacounty.gov. Landline phones registered at your address are automatically enrolled, but cell phones and email addresses require manual registration. This sign-up is essential for anyone in the hills, canyons, or foothill communities.
San Diego County — SDEmergency
San Diego County's system at sdemergency.com divides the county into hundreds of evacuation zones and lets you register multiple addresses — useful for families spread across different parts of the county.
Sonoma County — SoCoAlert
After the deadly 2017 Tubbs Fire, Sonoma County significantly upgraded its alert infrastructure. Sign up at socoemergency.org to receive alerts via landline, cell, text, and email.
San Bernardino County — TENS
San Bernardino County uses the Telephone Emergency Notification System (TENS), allowing registration of cell phones in addition to automatically enrolled landlines.
Marin County — Alert Marin
Marin County's Alert Marin system is accessible through the Marin County OES website. Fire Safe Marin recommends registering for both Alert Marin and Nixle for comprehensive coverage.
Layer 3: CAL FIRE and Statewide Resources
While CAL FIRE doesn't operate a direct push-notification system for individual homeowners, it provides several tools that complement your county's alerts. The CAL FIRE incidents page at fire.ca.gov/incidents provides real-time updates on active fires across the state — bookmark it and check during Red Flag conditions.
Watch Duty is a nonprofit app that has become one of the most widely used wildfire monitoring tools in California. It provides real-time fire perimeter mapping, evacuation zone status, and push notifications for active incidents near locations you specify. It's free with optional premium features. PulsePoint aggregates public safety incident data from fire and police dispatch systems and can surface early indicators of fire activity before official alerts are issued.
Layer 4: Red Flag Warnings and NWS Alerts
The National Weather Service issues Red Flag Warnings when conditions are ripe for fast-moving, dangerous wildfires: low humidity, high winds, and critically dry vegetation. Sign up for NWS weather alerts at weather.gov by entering your zip code and subscribing to email or text alerts. Red Flag Warnings are not evacuation notices — they're a signal to take preparedness steps: fill up your gas tank, charge your go-bag devices, and monitor conditions closely.
How to Register Multiple Addresses
One of the most underused features of county alert systems is the ability to register multiple addresses. Most platforms allow you to add several locations to a single account. Take advantage of this to monitor your primary home, a vacation property, your workplace, your children's school or daycare, and an elderly parent's home. Receiving an alert about an evacuation zone near your child's school gives you critical time to coordinate pickups before roads become congested.
What to Do After You Sign Up
Signing up is step one. Test your alerts when counties run periodic tests. Update your information annually if you change phone numbers or addresses. Register for calls, texts, and email — multiple channels increase the chance at least one gets through during network congestion. And know your evacuation zone designation before a fire starts, so you can act immediately when you receive an alert.
Frequently Asked Questions
Do I need to sign up, or will I automatically receive wildfire alerts?
Landline phones registered to a physical address are often automatically enrolled, but cell phones and email addresses almost always require manual registration. Since most households no longer have landlines, assume you are not automatically enrolled and register at your county's OES website.
What's the difference between an evacuation warning and an evacuation order?
An evacuation warning means a fire threat exists in your area and you should be ready to leave immediately. An evacuation order means you must leave now — remaining may be illegal and is life-threatening. Don't wait for an order to start moving. If you receive a warning, treat it with urgency.
Are these alert systems free to use?
Yes. County emergency alert systems are free public services. Some third-party apps like Watch Duty offer free tiers with optional paid upgrades, but the core notification functions are available at no cost.
Can I sign up if I'm a renter, not a homeowner?
Absolutely. Emergency alert systems are available to all residents, regardless of whether you own or rent. Your safety isn't contingent on property ownership.
What if I live near a county border?
Sign up in both counties. A fire that starts in the adjacent county could threaten your property before your own county issues an alert. The few extra minutes of advance notice can be invaluable.
Are there alerts for Public Safety Power Shutoff (PSPS) events?
Yes. PG&E, SCE, and SDG&E each have separate PSPS notification systems. Sign up at your utility's website in addition to your county's emergency alert system.
Sign Up Before Fire Season, Not During It
The best time to register for wildfire alerts is right now — not when you smell smoke, not when a Red Flag Warning is issued, and definitely not when an evacuation order has already been declared. During active emergencies, county websites slow down, cell networks jam, and the window for calm preparation closes fast.
Set aside five minutes today. Find your county's system, complete your registration, and download Watch Duty. Share the links with neighbors and family who may not be signed up yet. The alert that wakes you in the middle of the night — with enough time to grab your go-bag and get out safely — is the alert you're registering for now.
