DENVER – There is a “significant" risk of flash flooding on the Cameron Peak Fire burn scar Friday, and flash flood watches are in effect from 11 a.m. through the evening across much of the Colorado High Country.

The National Weather Service said rainfall rates could reach an inch to an inch and a half per hour Friday afternoon and that several rounds of rainfall are possible.

The flash flood watches are in effect until 9 p.m. Friday for the time being, with the highest risk of flash flooding over the Cameron Peak, East Troublesome, Williams Fork and Calwood burn scars.

The significant flash flood threat for the Cameron Peak burn scar will be in effect from roughly 2 p.m. through 5 p.m., according to the National Weather Service. The threat for the East Troublesome, Calwood and Williams Fork burn scars is “elevated” for most of the late morning into the evening.

The monsoon moisture will move from the west to the east as the day goes on, and showers and thunderstorms are expected to begin in the mountains and move into the foothills and metro area again to bring widespread precipitation to Colorado, according to the NWS.

The best chance for storms will be between 11 a.m. and 6 p.m., the NWS said.

Flooding risk at Colorado's burn scars Friday

In southwestern Colorado, a flash flood watch is in effect from noon through this evening for the San Juan Mountains, the Colorado River Basin, the Elk Mountains, Sawatch Mountains, Mosquito Range and Flat Tops, including the Grizzly Creek Fire burn scar.

Flash flooding has been seen all over Colorado this week. One person died and three others are still missing after a mudslide and flash flooding up Poudre Canyon on Tuesday evening.

Several mudslides in Grand County this week have closed Colorado Highway 125, which remains closed north of Granby to Rand Friday morning.

And I-70 through Glenwood Canyon remains closed because of mudslides from west of Gypsum all the way through Rifle.

And in Pitkin County, flooding closed Avalanche Creek Road Thursday, which remains closed.

The anticipated flash flooding in Larimer County could affect search operations for the three adults missing in Tuesday’s Black Hollow Drive mudslide, which were expected to continue Friday.
