Description and History:
Winter storms are one of the most common natural hazards in Larimer County, bringing heavy snow, blizzards, ice, extreme cold, and high winds that can disrupt transportation, utilities, businesses, and emergency services. Between 1996 and 2025, the county experienced 622 winter storm events, making severe winter weather an annual occurrence. While injuries and fatalities have been relatively uncommon, major storms have caused significant impacts, including road closures, power outages, damaged infrastructure, and millions of dollars in property damage.
Winter storms pose risks to everyone in Larimer County, particularly travelers, older adults, people with disabilities, and those who rely on electricity for life-sustaining medical equipment. Heavy snow and ice can bring down trees and power lines, isolate communities, damage roofs, and interrupt essential services. Remote mountain communities and areas above 6,000 feet are especially vulnerable due to more frequent and severe snowfall, while closures of major transportation corridors such as I-25 and U.S. 36 can disrupt travel, commerce, and emergency response.
Climate change is expected to influence winter storms by producing warmer winters overall while increasing the likelihood of heavier snowfall over shorter periods. Earlier snowmelt, changing precipitation patterns, and more intense winter weather events could place additional stress on infrastructure, transportation systems, and public safety. As Larimer County continues to grow, ensuring that new development meets modern building standards and improving emergency preparedness for rural communities will be important for reducing future impacts from severe winter storms.
Personal Preparedness:
Residents can reduce the impacts of winter storms by preparing their homes, vehicles, and families before severe weather occurs.
- Stay informed by monitoring weather forecasts, Winter Storm Warnings, Blizzard Warnings, and Wind Chill Warnings, and sign up for local emergency alerts.
- Build an emergency kit with enough food, water, medications, flashlights, batteries, blankets, and pet supplies to be self-sufficient for at least 72 hours.
- Prepare for power outages by charging electronic devices, keeping backup batteries or generators (used safely outdoors), and having alternative heat sources if available.
- Winterize your home by insulating pipes, servicing heating systems, sealing drafts, and knowing how to safely shut off utilities if needed.
- Prepare your vehicle with an emergency kit that includes blankets, warm clothing, food, water, a shovel, ice scraper, jumper cables, sand or cat litter for traction, and a fully charged phone.
- Avoid unnecessary travel during severe winter weather. If travel is necessary, let someone know your route and expected arrival time.
- Dress for the weather by wearing multiple warm layers, waterproof outerwear, hats, gloves, and insulated boots to reduce the risk of frostbite and hypothermia.
- Check on vulnerable neighbors such as older adults, people with disabilities, and anyone who relies on electricity for medical equipment during extended power outages.
These simple preparedness steps can help keep you and your family safe while reducing the impacts of severe winter weather.
