The potential for heavier snowfall in the western U.S. could lead to hazardous road conditions, especially in mountain passes. Drivers in Colorado's I-70 corridor, for example, may face traction requirements due to wet snow, freezing temperatures, and overnight refreezing. While increased precipitation could benefit water supplies in drought-stricken areas, warmer temperatures in the northern U.S. may result in rain rather than snow, impacting winter sports and snowpack-dependent regions. Forecasters caution that the outlook is subject to change as the season progresses.
