California faces longer, hotter, and more complex fire seasons each year. For residents across the state, real-time wildfire maps have become essential—not for watching fires from afar, but for staying aware and knowing when to act. The right combination of tools can help families make informed, safe decisions. Here’s how to find, read, and use wildfire maps to stay ready.
In Short
California’s wildfire season demands real-time awareness. No single map gives the full picture. Use a combination of CAL FIRE, InciWeb, and your county GIS map for verified updates. Pair those with official alerts like Red Flag Warnings and the Wireless Emergency Alerts system. Always act on evacuation orders early. Maps are tools for readiness, not reassurance.

The Essential Map Stack Every Californian Should Bookmark
Because a single map rarely gives the full picture, California’s most effective fire monitoring setup relies on several trusted sources working together. Below are the key ones every resident should know and bookmark.
CAL FIRE Statewide Fire Map
The CAL FIRE map is California’s official, verified source for active wildfire incidents. Updated multiple times a day, it includes fire names, perimeters, containment levels, and response details. Each symbol represents a verified event, confirmed by firefighting agencies on the ground. This is the first place to check for reliable information during fire season.

InciWeb (Incident Information System)
InciWeb is the federal wildfire incident portal managed by the U.S. Forest Service. It covers large or multi-agency incidents across the West and provides detailed updates, closure notices, maps, and community meeting notes. InciWeb is especially helpful when fires cross county or state lines or when multiple agencies are coordinating response efforts.
NIFC & Fire Weather Intelligence
The National Interagency Fire Center (NIFC) provides national-level maps and forecasts, including seasonal fire potential and fire weather outlooks. While not as granular as CAL FIRE, NIFC data helps Californians anticipate periods of elevated fire risk.
How to Read Fire Map Layers and What They Mean
Understanding Perimeters and Hotspots
Perimeter lines show the current boundaries of a fire, while hotspots mark areas of detected heat. Hotspot icons are often from satellite detections and may not be ground-verified. Always check the map's "last updated" timestamp — a timestamp more than an hour old may no longer reflect current conditions.
Live Cameras and Thermal Layers
California’s AlertWildfire camera network allows anyone to view live feeds from mountaintop cameras across the state. Use cameras to confirm official data, not to predict fire behavior. Thermal and infrared layers can help visualize fire spread, but they should never replace official updates from incident commanders or local authorities.
Update Frequency and Data Sources
Each mapping source refreshes at different rates: satellite heat detections may update every 15–30 minutes, while verified perimeters (from ground crews/aircraft) can take several hours. CAL FIRE and InciWeb rely on ground reports for confirmation, which improves accuracy but can introduce delays. Combine multiple sources rather than relying on a single feed.
Pairing Maps with Alerts for Faster Action
Red Flag Warnings and Weather Alerts
A Red Flag Warning from the National Weather Service signals conditions ideal for rapid fire growth. When a Red Flag is in effect, immediately prepare—charge devices, fuel vehicles, and review evacuation plans. A Red Flag period raises the chance that small ignitions spread quickly.
Wireless & Emergency Alert Systems (WEA & EAS)
California’s Wireless Emergency Alerts (WEA) and Emergency Alert System (EAS) push official notifications to phones, radios, and TVs. Keep alerts enabled on your devices and sign up for county notifications when available.
Trusted Apps and Alert Sources
Combine your maps with apps like the official CAL FIRE Ready for Wildfire app, Watch Duty, and FEMA. CAL FIRE provides verified incident data and evacuation notices; Watch Duty can supply near-real-time reports from verified community responders. Use at least two alert sources for redundancy during outages.
County & Regional Fire Map Resources (Quick Links)
For faster access during fire season, keep these local links saved (replace with your county URLs):
- Los Angeles County: Emergency Operations GIS Map
- Sonoma County: Emergency Fire Map
- San Diego County: Wildfire Map
- Santa Barbara County: Live Emergency Zones Map
Pro tip: Save your county’s emergency page to your phone home screen (or bookmark) so you can open it quickly even during heavy network congestion.
Accuracy & Limits: When to Act, Not Just Watch
What “Estimated” and “Unverified” Mean
An estimated perimeter may not match the actual fire edge. Unverified hotspots can be caused by reflections, industrial heat sources, or sensor error. Use these indicators for early awareness — but do not treat them as definitive proof of danger or safety.
Evacuation-First Decision Making
If your area receives an evacuation warning or you see heavy smoke nearby, prepare to leave immediately. Fires can change direction quickly; waiting for map confirmation can cost valuable time. Maps should support decision-making, not delay it.
Why Watching Isn’t Enough
Frequent map refreshes can create false comfort. The most effective action is preparation: know your routes, pack essentials, and have a plan. Treat maps as tools for readiness, not entertainment.
Quick Prep Steps
- Keep a “go bag” with N95 masks, medications, chargers, important documents, and water.
- Ensure everyone knows two evacuation routes and a family meeting place.
- Sign up for local alerts (ReadyForWildfire.org and your county’s portal).
Household Coordination
Preparation only works if every member of your household understands the plan — and can act on it under stress. Start by assigning clear responsibilities before fire season begins. For example, one adult handles pets, another secures important documents, and older children know which bags or items to grab. Walk through the plan step by step so there’s no confusion during an emergency.
Run practice drills at least once a year — ideally at the start of each fire season — and test both primary and alternate evacuation routes. Keep vehicles fueled to at least half a tank, and store an extra set of car keys in your go bag. If you have elderly relatives, children, or individuals with limited mobility, pre-identify who will assist them and how. The goal is to eliminate hesitation.
Also make sure every household member knows how to open the garage manually in case of power failure and where the shut-off valves for gas and water are located. Keep fire extinguishers easily accessible and test smoke alarms monthly. If you own a FORT™, include it in your practice drills — everyone should know its location, how to access it, and what the sequence would be if evacuation routes were blocked.
Finally, post your emergency contacts and evacuation plan on the inside of a cabinet door or refrigerator where it’s visible even if cell service is down. Familiarity builds confidence, and confidence saves time when every second counts.
Digital Backup & Communication
When wildfires strike, communication networks can fail, so redundancy is key. Back up all essential documents — property deeds, insurance papers, medical information, and identification — to both a secure cloud folder and an external USB drive kept in your go bag. Take photos or videos of your home’s interior and exterior for insurance purposes and store copies safely offline.
Create a shared family contact sheet with at least one out-of-area relative designated as a check-in point. During emergencies, text messages often go through when calls do not; make texting your default. Save emergency numbers for your local fire department, sheriff, and county alert line in every phone, and keep a printed copy in your emergency kit.
Download offline maps from Google Maps or similar apps so you can navigate without cell service. Keep portable battery banks or a hand-crank radio charged for use during power outages.
If you own a FORT™, remember that it is equipped with a Wi-Fi and cellular repeater to assist with communication while inside, and it automatically notifies Wildfire Safety Systems when its doors are opened. This notification confirms the unit is in use and supports emergency awareness if evacuation is not possible.
By planning backups and using multiple communication methods, your family will stay connected and informed even when networks are strained.

- Preparation beats observation: Watching maps is helpful; readiness saves lives.
Final Note: Evacuate Early, Stay Informed
Wildfire maps are tools for awareness and safety, not reassurance. Keep them bookmarked, but act on alerts—not visuals. California’s agencies provide reliable systems to help you stay informed; your job is to be ready when it matters most.
In rare, last-resort situations when evacuation isn’t possible, purpose-built, tested refuges such as a FORT™ can provide temporary protection. Always evacuate if you can; a refuge is a backstop, not a replacement for evacuation.
