Livermore Fire Protection District is leading operations, with support from the Larimer County Sheriff’s Office and regional partners. No injuries or structural losses have been confirmed at this time, but crews continue to assess conditions.
The wildfire is burning amid extreme fire danger. The National Weather Service has issued a Red Flag Warning from 2 p.m. to 10 p.m. Saturday, citing record March heat, humidity as low as 3 percent, and wind gusts up to 35 mph. These conditions significantly increase the potential for rapid and unpredictable fire growth.
Officials are urging residents across Northern Colorado to remain vigilant, avoid any activity that could spark a fire, and be prepared for changing conditions throughout the day.
Motorists near U.S. Highway 287 and surrounding areas should expect emergency activity and avoid the immediate vicinity as firefighters continue suppression efforts.
