Grand Junction, Colo. – Storms will keep western Colorado on alert this week as October begins with a mix of sunshine, rain, and gusty winds. Travelers along I-70 should prepare for delays from scattered thunderstorms and pockets of heavy rainfall expected through Wednesday. Lightning and strong wind gusts could complicate morning commutes and outdoor plans.
According to the National Weather Service in Grand Junction, thunderstorms remain likely across western and central Colorado through Tuesday night, with additional development possible Wednesday. The heaviest rain may fall over higher elevations, but localized flooding and minor travel disruptions could reach valleys and highways.
Grand Junction and the Grand Valley may see sunshine early this week, but by Wednesday afternoon, winds shifting northwest could spread instability. The San Juan and Gore ranges face the highest risk of rain and mountain snow accumulation, which could impact backcountry routes. Drivers should monitor updates before heading into passes.
After midweek storms, western Colorado turns warmer and drier, with highs in the low 80s expected by Thursday. Another round of showers may push back into the region Friday evening, creating another challenge for weekend travelers. Residents are encouraged to secure outdoor items, prepare for wet road conditions, and avoid unnecessary travel during lightning periods.
Weather threats ease heading into Saturday, with cooler, clearer skies expected to close the week. Advisories remain in place, and additional updates are likely if storms intensify.
