GRAND JUNCTION, Colo. – Drivers across western Colorado should prepare for dangerous travel conditions as thunderstorms target the I-70 corridor this week. Gusty winds, lightning, and heavy downpours could bring flash flooding, especially near recent burn scars and steep mountain roads.

According to the National Weather Service in Grand Junction, isolated storms will develop Tuesday afternoon before growing more widespread Wednesday through Friday. The most intense periods of rain are expected midweek when a disturbance sweeps through the Rockies. Officials urge drivers to avoid low-lying crossings, slow down on wet pavement, and remain alert to changing conditions.

Communities from Grand Junction to Glenwood Springs face the highest risk for flooding and road delays. Thunderstorms may produce dangerous cloud-to-ground lightning, posing additional hazards for hikers, rafters, and anyone outdoors. Scattered activity lingers into Saturday before tapering late in the weekend.

Residents should keep cell phones charged in case of power outages and check local alerts before traveling into the mountains. Spotters are encouraged to report any flooding to the National Weather Service office.

While today stays sunny and dry, conditions will deteriorate quickly starting Tuesday afternoon. Officials emphasize that even short bursts of heavy rain can trigger flooding along small creeks and canyons.

Warnings remain in effect through late week, with more updates expected as storms develop.
