From CAIC and CDOT Use Swiss Model to Improve Avalanche Forecasting

How could improved avalanche forecasting affect Summit County's operational safety?

Possible What happens if… A possibility worth considering, not a forecast.

Better avalanche forecasting may improve safety on I-70 in Summit County The collaboration between the Colorado Avalanche Information Center and the Colorado Department of Transportation utilizes the Snowpacker model, developed by the SLF in Switzerland, to simulate snowpack instability. This tool helps forecasters determine how far avalanches might travel, allowing for more precise risk assessment on routes like I-70 and Highway 6 near Loveland Pass. By providing better predictive capability, the system aims to improve operational safety and reduce the risk of unnecessary road closures or late closures that could endanger vehicles in the area.

The facts so far

As reported. Each one links to where it comes from.

  • CAIC and CDOT are using a Swiss-developed Snowpacker model for driver safety.kktv.com
  • The model simulates what the snowpack layers look like and shows where instability can be.kktv.com
  • The current focus is on I-70 and Highway 6 near Loveland Pass.kktv.com
  • A pilot year showed success, with a simulated avalanche stopping well short of the highway.kktv.com

Why it matters

For Summit County, which relies heavily on mountain passes like I-70 for access and tourism, operational safety is critical. Improved avalanche forecasting means that CDOT can manage road closures and warnings with greater accuracy, reducing the risk to drivers and minimizing disruptive closures that impact local businesses and visitor access.

This initiative is part of a broader effort in Colorado to leverage advanced geospatial data and international research to manage severe weather risks. CAIC and CDOT are expanding the areas they survey with drones, aiming to gather more data to further test and improve the effectiveness of the Snowpacker tool across more high-risk zones.

What we don't know yet

  • How many additional areas are being surveyed this winter?
  • What is the expected timeline for the full implementation of the Snowpacker model?

What would change this answer

The expansion of surveyed areas includes more high-traffic routes in Summit CountyThe positive effect on local operational safety and tourism stability would become stronger and more immediate.
The model fails to accurately predict the path of a major avalanche eventConfidence in the tool would decrease, potentially leading to a return to older, more conservative forecasting methods.
