LARIMER COUNTY, Colo. (CBS4)– Flash flooding and mudslides in Larimer County caused the closure of Highway 14 in the Poudre Canyon for several hours on Friday. It also put dozens of residents on a pre-evacuation alert.

A lot of debris and ash was flowing out of Hewlett Gulch into the Poudre River.

Highway 14 reopened at 7:30 p.m.

Roads in Rist Canyon were also affected for a time, particularly Davis Ranch Road. Traffic that was being diverted in this area has since been allowed to continue through.

This is in the High Park Fire burn area. The fire burned more than 87,000 acres after it was started by lightning June 9. Firefighters have the fire 100 percent contained.

Charred hillsides are vulnerable to erosion and flooding during downpours because they have less vegetation to soak up rain, and burned soils can repel water.

The flash flooding also affects the Hewlett Gulch Fire burn area.

There is no evacuation site open at this time but will be opened if an evacuation is necessary. A total of 227 emergency notifications were sent. T

Crews with the Colorado Department of Transportation cleaned up the debris.
