Billings, Montana – Warm, dry, and windy conditions are creating elevated grass fire concerns across south-central Montana today, particularly along major transportation corridors west of Billings.
According to the National Weather Service in Billings, temperatures are expected to reach the 50s to lower 60s, while relative humidity drops to 20 to 30 percent. These conditions will combine with strong winds, including gusts between 30 and 50 miles per hour, highest along the western foothills and adjacent plains.
Forecasters warn that the combination of dry grasses, low humidity, and gusty winds can allow fires to ignite easily and spread rapidly, even from small sparks. As a result, residents and travelers are urged to avoid activities that could start a fire.
Areas of greatest concern include lower elevations from Billings westward, affecting travel along Interstate 90, U.S. Highway 212, and U.S. Highway 310, where vehicles, roadside debris, and equipment can inadvertently create ignition sources. Wind-driven fires near highways can spread quickly and may reduce visibility for motorists.
The National Weather Service advises against outdoor burning, and cautions drivers to ensure tow chains are not dragging, properly dispose of cigarettes, and avoid parking vehicles on dry grass. Even brief sparks can trigger fast-moving grass fires under today’s conditions.
Winds are expected to remain breezy through the afternoon before gradually easing later tonight. No precipitation is expected, and fuels will remain dry.
The elevated fire risk may be especially relevant for commuters, ranchers, construction crews, and travelers along I-90 during peak daytime hours. Officials encourage residents to remain vigilant and report any signs of smoke or fire immediately.
This outlook is based on conditions observed early Wednesday morning and may be updated if wind speeds or humidity levels change.
