An early winter storm swept across Montana on October 11, bringing heavy snowfall, damaging trees, and causing widespread travel disruptions. The system, fueled by cold air and storm remnants, impacted several communities, including Great Falls, Lewistown, and Billings.
Record-Breaking October Snowfall
The National Weather Service recorded 11.1 inches of snow in Great Falls by noon on October 11. This is the city’s snowiest October since 2020. The storm was particularly intense; this single day of snowfall accounted for more than 25% of the 41.7 inches of snow Great Falls received during the entire previous winter season.
Travel Disruptions and Road Safety
The storm created hazardous conditions for motorists across the state. In Butte, westbound lanes on Homestake Pass were closed for several hours on October 11 after a semi-truck overturned, resulting in an injury. Emergency crews cleared the scene, but many travelers were stranded for hours.
Local authorities urge caution as the region adjusts to the early arrival of winter. Experts recommend the following safety practices for navigating icy mountain passes:
- Reduce speed significantly on slick roads.
- Increase the distance between your vehicle and the one ahead.
- Check official road condition reports before departing.
- Carry emergency supplies, such as blankets and food, in your vehicle.
Community Impact and Power Outages
The snow was wet and heavy, causing structural damage across the region. In Great Falls, residents reported fallen tree branches, including one instance where a tree collapsed onto a family vehicle. The weight of the snow also raised concerns about power outages, as heavy accumulation on power lines can cause service interruptions.
Staying Prepared for Early Winter Weather
While Montana residents are accustomed to winter, this early storm served as a reminder of the importance of preparedness. Residents should ensure home heating systems are functional and keep essential supplies on hand in case heavy snow leads to power failures.
As of October 12, road crews were clearing remaining icy patches. While primary routes like Homestake Pass have reopened, motorists should remain vigilant as temperatures fluctuate throughout the fall.
