Heavy rain is set to continue in Colorado through the end of the week, likely to cause more travel-related issues around the state. As these storms continue, Coloradans should expect an elevated risk of flash flooding and debris flow in some parts of the state through Saturday.

If rains continue as expected, it could mean that I-70 through Glenwood Canyon has been closed for five consecutive days this week, starting with a closure that happened this Tuesday, extending into Wednesday, with more closures possible on Thursday, Friday, and Saturday. Other impacts around the state are also expected.

"Heavy rainfall and flash flooding will be possible this afternoon and evening, especially along the Continental Divide and across Lake and Chaffee counties," the National Weather Service (NWS) warned in a recent outlook addressing Thursday weather. "Farther east, storms will be more scattered to isolated in nature over the Sangre de Cristo Range, the Wet Mountains and Teller County, though if storms move across existing burn scars, flash flooding may be possible."

Interstate 70 in Glenwood Canyon was shut down due to the flash flooding and mudslides on Tuesday evening. Situated near the Grizzly Creek Fire burn scar, this particular area of the interstate is highly susceptible to post-wildfire flooding and mudslides due to lasting impacts of the blaze.

A report from 9News says the Tuesday night closure of Interstate 70 through the Glenwood Canyon area is the 8th time this stretch of road has been closed this summer.

Other roads have also recently faced closures, including Highway 125 – when mudslides trapped vehicles – and Highway 14, when a fatal flash flood occurred.

Scattered thunderstorms will continue to develop Friday and Saturday afternoon and into the early evening hours over the central mountains and the San Luis Valley, with impacts expected along the I-25 corridor and central plains, including the Palmer Divide in El Paso County and the Raton Mesa area.

In addition to the torrential rain, there is also a potential for hail up to the size of an inch, cloud to ground lightning, and erratic wind gusting up to 50 mph.

Additional burn scars at risk for post-fire flooding include Cameron Peak, East Troublesome, Calwood, and Williams Fork.
