GRAND JUNCTION, Colo. – Heavy rain and embedded thunderstorms are targeting western Colorado this Friday morning, prompting Flash Flood Watches across the region and travel concerns along I-70 through Sunday. Widespread downpours could trigger flooding near recent burn scars, slot canyons, and low-lying urban zones, particularly through Mesa, Delta, and Montrose counties.
According to the National Weather Service in Grand Junction, the heaviest rainfall will arrive Saturday morning as a surge of moisture pushes into the Four Corners. Showers will remain scattered but steady through Sunday before cooler, drier air returns early next week. Motorists along I-70, U.S. 50, and Highway 550 should watch for ponding and rockfall risks in mountain passes.
Residents are urged to avoid driving through flooded areas and to secure outdoor decorations or pumpkin patch displays ahead of gusty afternoon storms. Flash flooding remains possible through late Saturday night, especially across the San Juan Mountains and Uncompahgre Plateau.
By Sunday, a clearing trend begins, though breezy conditions and lingering showers could still dampen early morning plans. The pattern shifts toward cooler, more stable weather next week — a welcome break after this wet Fall weekend.
Cooler highs in the 60s and 70s are expected early in the week, with lows dipping into the 40s across the valleys. Leaf-peepers and outdoor event planners should anticipate improved conditions by Tuesday and Wednesday, perfect for fall hikes and late-October decorating.
