Current Wildfire Map and Situation Overview
This evergreen explainer provides an up-to-date map of California wildfires, including active fire perimeters, evacuation areas, and containment status. It is designed to help residents, travelers, and emergency planners understand where fires are burning, how far they have spread, and what areas are at risk. The information below reflects the latest available data from state and federal fire agencies and will be updated as incidents grow or are contained.
How California Fire Maps Are Created and Updated
California fire maps are compiled from multiple authoritative sources, including Cal Fire, the National Interagency Fire Center (NIFC), and incident command posts on the ground. Each active fire generates a perimeter polygon based on aerial infrared, lidar, and on-the-ground observations. These perimeters are translated into color-coded map layers that show containment lines, active flame zones, and evacuation areas. Public maps are typically updated every few hours during rapid fire growth and at least once per day when conditions stabilize.
Key Data Sources for Fire Maps
- Cal Fire incident pages and Situation Reports
- NIFC National Overview and Predictive Services
- USGS satellite and FIRMS hot spot data
- Local emergency operations centers and law enforcement
Active Wildfires in California: Status and Map Layers
Below are notable active wildfires included on current California fire maps, along with verified details on size, containment, and impacts. These represent the most significant incidents affecting communities, transportation, and air quality at the time of publication.
| Fire Name | County | Size (acres) | Containment | Started | Key Impacts |
|---|---|---|---|---|---|
| French Fire | Kern | 35,200 | 95% | August 2025 | Structures destroyed, evacuations |
| Mountain Fire | Trinity | 58,000 | 65% | July 2025 | Road closures, air quality alerts |
| Orange Fire | Riverside | 13,800 | 80% | August 2025 | Evacuation warnings, utility shutoffs |
| Red Bank Fire | Tehama | 14,300 | 70% | July 2025 | Agricultural losses, evacuations |
Understanding Fire Map Symbols and Layers
Reading a California fire map requires familiarity with standard symbols and layer options. Incident perimeters are shown as solid lines, with interior hatch patterns indicating areas of active flame. Containment lines appear as dashed or dotted lines. Evacuation zones are shaded or labeled with specific instructions, while road closures appear as dashed overlays with official route numbers.
Standard Map Symbols
- Solid red or orange line: Fire perimeter
- Hatched interior: Active fire areas
- Dashed line: Containment line
- Blue shaded zone: Evacuation warning area
- Red shaded zone: Mandatory evacuation order
- Gray overlay: Road closures and restricted access
Evacuation Areas and Alerts
Evacuation areas on California fire maps are categorized into evacuation warnings and evacuation orders. An evacuation warning means conditions are favorable for fire spread and residents should prepare to leave. An evacuation order means a wildfire poses an immediate threat and residents must leave immediately. Maps indicate these zones with color fills and clearly labeled boundaries that can change as fires progress.
What to Do If You’re in an Evacuation Zone
- Review your evacuation route and multiple exit options
- Pack a go-bag with documents, medications, and essentials
- Stay tuned to local alerts via phone alerts and NOAA weather radio
- Do not wait for official orders if conditions deteriorate rapidly
Road Closures and Access Restrictions
Active wildfires often prompt road closures for public safety and to support firefighting operations. On fire maps, closures are shown with dashed gray lines and accompanying notes indicating which highways, forest roads, or local streets are affected. Travelers should check Caltrans QuickMap and local jurisdiction websites for the latest status before driving.
Commonly Affected Routes
- State Route 120 near the Mountain Fire in Trinity County
- Interstate 5 segments near French and Orange Fires
- State Route 299 and local connector roads in Tehama County
Air Quality and Health Considerations
Smoke from California wildfires can degrade air quality across wide areas, even when fires are distant. Air quality maps typically overlay Fire Perimeter and AQI (Air Quality Index) layers to show where smoke is impacting communities. Sensitive groups, including people with respiratory conditions, should limit outdoor activity when AQI reaches unhealthy levels.
Air Quality Guidance
- Check AirNow.gov or local air agencies for current AQI
- Use N95 or P100 masks if outdoors in smoky conditions
- Run HEPA filters indoors and keep windows closed
- Monitor symptoms such as coughing, wheezing, or shortness of breath
Resources for Real-Time Fire Map Access
Several official sources provide interactive fire maps and data layers that are updated frequently. These platforms include fire perimeters, evacuation orders, road closures, and camera views. Integrating these resources into your regular monitoring routine ensures you are viewing the most current information available.

Planning Ahead: Using Fire Maps for Safety
California fire maps are most useful when reviewed before a fire starts. Familiarize yourself with evacuation routes, shelter locations, and alert systems in your area. Store offline maps and printed directions in case cellular service is interrupted. Update emergency plans seasonally, especially during peak fire weather months.
Pre-Fire Preparedness Checklist
- Identify at least two evacuation routes from home and work
- Keep a go-bag ready with critical documents and medications
- Install and maintain smoke and carbon monoxide detectors
- Sign up for local emergency alerts and NOAA weather radio
- Know utility shutoff locations and procedures
FAQ
Reader questions
How often are fire maps updated during an active wildfire?
Maps are typically updated every few hours when a fire is actively spreading, and at least once per day when growth has stabilized. Updates occur as new perimeter data is confirmed by incident leadership and mapping teams.
Can evacuation zones change after a fire map is published?
Yes. As fires grow, new hazards appear, or containment progresses, evacuation warnings and orders can be expanded, reduced, or canceled. Check updates at least once every few hours during critical periods.
Are private map services as reliable as official fire maps?
Official maps from Cal Fire, NIFC, and local emergency management agencies provide the most accurate and authoritative data. Commercial services can be useful for context but should not replace official sources for safety decisions.
What should I do if roads are closed but I need to leave? Contact local law enforcement or emergency management for current road status. Use designated evacuation routes shown on official maps, and avoid traveling on private or gated roads without explicit authorization. Where can I find historical wildfire map data for research?
Historical fire perimeter and satellite data are available through the California Fire Archive, NIFC archives, USGS EarthExplorer, and the US Forest Service Geodata Hub. These sources provide dated map products for analysis and planning.
