Frederick County Wildfire and Snowmass Fire Risk Modeling — November 10, 2026

Today's news starts in western Virginia, where crews contained most of a wildfire that forced evacuations. In Colorado, two mountain towns are working out how to use new wildfire risk data. We also have a California fire chief's case for federal forest policy and a guide to indoor air monitors.

Frederick County, Va. wildfire reaches 90% containment

A wildfire in western Frederick County, Virginia, was 90% contained Monday evening, WJLA reports. It burned between Cove Campground and Shawneeland, west of Winchester. Evacuations started on a few streets and later grew to more than 20 as the fire moved uphill. Some Shawneeland residents were allowed to return home.

County officials expected the fire to keep burning inside containment lines, and crews planned to stay through Tuesday to watch conditions. Officials asked drivers to use caution because smoke could linger. If you live nearby, lingering smoke is a good reason to keep windows closed.

Snowmass Village and Marble test new wildfire risk modeling

Snowmass Village and Marble, Colorado, are two of the first communities in the world to complete advanced modeling that shows where wildfire mitigation can have the biggest impact, according to Aspen Journalism in the Aspen Daily News. The model, called AGNI-NAR, was developed by Hussam Mahmoud of Vanderbilt University. It uses topography, vegetation and wind data, plus surveys asking homeowners about features like roof type, siding and nearby vegetation.

The towns are still working out how to use the data while protecting homeowners' privacy. Snowmass Village's survey had a 20% response rate. The Wildfire Collaborative Roaring Fork expects to present modeling results this month for Carbondale and areas served by the Aspen Fire Protection District.

A Ventura County fire chief makes the case for the Fix Our Forests Act

In an opinion piece in the Ventura County Star, a fire chief who led the Ventura County Fire Department for 15 years urges Congress to pass the bipartisan Fix Our Forests Act. The writer argues that decades of putting out every fire, along with resistance to prescribed burning, let fuels build up to unsafe levels.

The piece calls for treating fire as a natural part of wildland ecology and managing land so that low-intensity fire can clear dead and diseased growth.

What home air quality monitors measure

SlashGear looks at five indoor air quality monitors, including the Qingping Air Monitor 2, Airthings Wave Plus, AirGradient One, Aranet4 Home and GoveeLife H5140. These devices generally track some mix of fine particles (PM2.5 and PM10), carbon dioxide, nitrogen oxides and volatile organic compounds, along with temperature and humidity.

The article notes that a monitor makes it easier to know when to run an air filter or open a window. During smoke events, a reading inside the house can show whether closed windows and filters are working.
