Intense flooding and mudslides occur close to the Lee Fire in the western region of Colorado

As cooler weather moves into Colorado, residents are bracing for potential storms. According to the National Weather Service (NWS) Boulder, storms are expected to move east through the late afternoon, with these systems passing over the plains in the evening.

The weather conditions have raised concerns, particularly in Rio Blanco County, where the Lee Fire has been burning for over 20 days. The fire, which has been mostly contained, has left the soil vulnerable to mudslides and flash flooding, especially after heavy rains.

Digital Media Producer at CBS Colorado in Denver, Christa Swanson, has been reporting on the aftermath of the mudslides and flash flood warnings in Rio Blanco County. In August 2025, heavy rains caused mudslides and flash flooding in the area following wildfires.

The NWS Boulder issued a flash flood warning for part of Rio Blanco County on Sunday afternoon. The warning was issued in an area including the Lee Fire, where the soil can become hydrophobic due to the burnt vegetation. This hydrophobic soil can lead to possible flash flooding or mudslides during a rainstorm.

The Rio Blanco County Sheriff's Office reported two mudslides: one on County Road 5 near mile marker 15 and another at County Road 8 and County Road 57 (Miller Creek). The Elk and Lee Fire Incident Command issued a warning of heavy rains causing flash flooding and blocking County Road 5.

Despite the risks, the flash flood warning for the Lee Fire area was lifted at 2:15 p.m. However, County Road 5 at mile marker 15 reopened with alternating one-lane traffic, advising travelers to allow for extra time. County Road 8 remains passable but is still muddy, and County Road 33 is also muddy, according to the Rio Blanco County Sheriff's Office.

Travelers near the burn scar areas are advised to use caution, as the Lee and Elk Fires remain active. Those nearby the burn scar area were also advised to stay clear. Christa Swanson continues to report on the situation, keeping the public informed about the potential risks and the ongoing efforts to ensure safety in the affected areas.
