Grand Junction, CO – Showers and thunderstorms are expected to develop again this afternoon across western Colorado, with the highest impacts along the Continental Divide.
According to the National Weather Service in Grand Junction, the San Juan Mountains will face the greatest risk of showers and thunderstorms Monday, September 29. Forecasters warn of heavy rain, lightning, gusty winds, and small hail as potential threats.
Lower elevations, including areas across the Grand Valley and western slope, are more likely to see increasing sunshine and near-normal temperatures. Conditions are expected to remain stable there, with only minimal shower chances.
Forecasters say today’s temperatures will remain close to seasonal averages, with a gradual warming trend setting in through the rest of the week. Chances for mountain showers will diminish steadily, allowing more consistent dry weather across Colorado by midweek.
Travelers along high mountain passes and outdoor recreation areas are urged to remain cautious, as storms may develop quickly in the afternoon hours. Lightning and brief downpours could impact visibility and hiking safety in exposed terrain.
The National Weather Service advises monitoring local forecasts for updates as conditions evolve.
