As Rising Temperatures Reshape Fire Risk, Fire Departments Must Adapt
As rising temperatures reshape fire risk, fire departments must rethink what it means to be prepared. That work starts before an emergency call, with a clear picture of local hazards, and continues through fire detection and evacuation decisions. Together, those responsibilities put planning, timely information, and community readiness at the center of adapting to a changing climate.
Fire Season Is Longer, and Risk Zones Are Expanding
Higher temperatures can leave vegetation drier, creating conditions that favor the spread of fire. The National Aeronautics and Space Administration (NASA) reports that extreme wildfire activity has more than doubled worldwide across a 21-year satellite record. NASA also cites a 35-year weather-data analysis showing that fire seasons in parts of the western United States lengthened by more than a month.
Development is changing exposure, too. The wildland-urban interface (WUI) is where homes meet or mix with forests or other wild vegetation.
According to the U.S. Department of Agriculture Forest Service, this area grew by 179,000 km² between 1990 and 2020, roughly matching Washington state’s size. WUI housing increased 46%, from 30 million to 44 million homes, during that period.
Longer fire seasons and expanding development increase the overlap between communities and wildfire hazards. Departments assessing local exposure must consider how both the landscape and the conditions around it have changed.
Why Pre-Incident Planning Matters More in a Changing Fire Landscape
Preparation starts with knowing what crews may encounter before a call arrives. Pre-incident planning involves recording hazards, water supplies, and access routes for a property or area before an emergency. As conditions change, those records need to be reviewed rather than remain a fixed snapshot of the past.
For example, fire departments across the U.S. and Canada, from Fort Lauderdale Fire Department in Florida to Seattle Fire Department in Washington, use First Due, a cloud-based Fire and EMS software platform built to help agencies run more of their operation in one place.
The platform brings functions such as pre-incident planning, incident reporting, ePCR, scheduling, personnel management, assets, hydrants, training, community engagement and mobile response into a single application.
For departments evaluating pre-incident planning software, the practical question is how readily crews can access current operational information. A connected platform can help departments keep planning, response, and records management information more accessible as fire risk changes, while leaving incident-specific judgments to responders.
Catching Fires Earlier Before They Spread
Planning addresses known hazards, while detection focuses on recognizing a new fire. Earlier identification can let responders assess an ignition before it grows, though conditions still shape how quickly crews can act.
To support earlier detection in Ukiah, California, wildfire-monitoring company Pano AI deployed four mountaintop camera systems with 360-degree views and artificial intelligence. The Ukiah Valley Fire Authority serves approximately 90 square miles, including extensive WUI areas. The partnership announcement describes the cameras as tools for spotting and assessing new ignitions.
In the partnership announcement, Fire Chief Doug Hutchison linked early detection to potentially lower suppression costs and improved firefighter safety. For other departments, the example raises the question of where additional observation could help responders recognize emerging threats. Detection technology supports that work, while crews remain responsible for assessing the fire and determining the response.
Getting Evacuation Orders Out Faster
Once a fire threatens a community, officials also need a way to communicate who should leave. Zone-based evacuation divides an area into predefined sections so authorities can direct orders to affected neighborhoods.
Emergency response software provider Genasys describes the Franklin Fire in Malibu, California, where Santa Ana winds helped the nighttime blaze triple in size within an hour in December 2024.
According to the company, the Los Angeles County Fire Department issued evacuation orders through Genasys Protect within that first hour. Its zone-based software supported agency coordination and provided residents with up-to-date instructions via a public app and website.
The company’s case study reports over 4,000 acres burned and over 40 structures destroyed, with no deaths. Genasys credits early notifications as a major factor in that outcome. Its account illustrates the role of targeted communication during an evacuation, without establishing that the software alone prevented deaths.
The Departments That Adapt Now Will Be Ready for What’s Next
Adaptation gives departments a reason to review preparedness as an ongoing responsibility. Pre-plans establish a starting point, while detection systems can flag emerging threats and evacuation procedures guide public communication. Each approach addresses a different stage of an emergency.
Departments can build resilience by reviewing how these responsibilities connect locally and identifying gaps before the next incident tests their readiness. The priority is preparation that keeps pace with changing conditions.
