Glenwood Canyon weather forecast calls for two days of showers and thunderstorms
The weather forecast for Glenwood Canyon calls for likely rounds of showers and thunderstorms on Wednesday and Thursday, up to an 80% chance of precipitation, and highway officials are bracing for a possible closure of Interstate 70 through the canyon.
There’s a chance for showers and thunderstorms starting at about noon Wednesday over the wildfire scarred-canyon, according to the National Weather Service. The 80% chance for precipitation Wednesday continues into Wednesday night.
More showers and thunderstorms are expected on Thursday, with a 70% chance for precipitation.
“Many storms will have the threat of heavy rainfall rates and gusty winds,” the weather service said. “Heavy rainfall rates or prolonged precipitation could impact burn scars and lead to other runoff issues during this time. The Grizzly Creek burn scar will be especially susceptible to flash flooding which will impact travel if this occurs.”
On Tuesday evening, the Colorado Department of Transportation issued a “Travel Alert” for I-70 and Glenwood Canyon, advising drivers to be in tune to the weather and to be prepared for the highway to close if flash flood warnings are posted.
“Plan ahead heavy rains expected,” CDOT said in a Twitter post.
On Friday, before the canyon reopened to traffic on Saturday morning, CDOT officials warned that the highway through the canyon will close again if conditions are deemed unsafe.
The canyon stretch of I-70 had been shut down since July 31 as crews worked to clear debris, rocks, timber and mud that slide onto the highway, causing substantial damage, after heavy rains. Repairs and construction continues on the road, including about a mile-long stretch in the Blue Gulch area, which is limited to one lane in each direction.
