Wildfires raging across California are now threatening critical transport infrastructure, including major highways and rail lines, prompting a coordinated response from federal and state agencies. In an unprecedented move, British emergency services have been deployed to share specialist tactics developed from their own experience with wildfires and urban interface incidents.
The fires, which have spread across multiple counties, have forced the evacuation of thousands of residents and the closure of sections of Interstate 5, a vital north-south corridor. The California Department of Transportation has warned of significant delays and advised motorists to avoid affected areas.
A team of experts from the London Fire Brigade and Scottish Fire and Rescue Service, alongside senior operational planners from the UK’s National Fire Chiefs Council, arrived in Sacramento on Tuesday. They are embedding with local incident command structures to advise on strategic resource management and community shielding techniques refined during the 2022 heatwave and subsequent wildfires in the UK.
“We are seeing fire behaviour in the urban fringe that is increasingly familiar to British crews,” said Deputy Chief Officer Anne-Marie Walker of the London Fire Brigade. “The integration of real-time drone mapping and predictive weather modelling here is something we can both offer and learn from.”
The tactical exchange is part of a broader bilateral agreement between the UK Home Office and the Federal Emergency Management Agency (FEMA) to enhance interoperability during extreme events. British specialists are also advising on retrofitting water supply points for defence against approaching flames, a tactic employed in parts of Surrey and Kent during recent scorching summers.
California Governor Gavin Newsom has declared a state of emergency for the affected counties, including Los Angeles, Ventura, and San Bernardino. In a statement, the governor thanked the UK for its “rapid and generous support” and noted that the collaboration was “a model for future international crisis response.”
The wildfires have already consumed over 120,000 acres, with containment at less than 15 per cent. Federal resources, including military aircraft and firefighting teams from the US Forest Service, are operating alongside state and local crews.
The British deployment, while small in numbers, is significant in symbolic terms. It marks the first time UK operational fire personnel have been embedded with US incident management teams for a wildfire event. The sharing of specialist tactics is expected to continue over the coming weeks, with potential implications for future transatlantic agreements on disaster resilience.
