UPDATE: The flash flood warning expired Thursday afternoon.

DENVER — A flash flood warning has created "a life-threatening situation" for people along the eastern section of the Cameron Peak Fire burn scar in Larimer County, according to the National Weather Service.

The NWS out of Boulder said rain is falling at a rate of 2 to 2.5 inches per hour, creating a flooding hazard for the Buckhorn Creek and Buckhorn Road area near the burn scar. The "short but intense" periods of rain will cause flooding and debris flows, the NWS said.

The flows — made of rock, mud, vegetation and other loose materials — will move through Buckhorn Creek and into nearby drainages.

The storm may cause flash flooding of streams and creeks, which can overflow into urban areas, highways, streets and underpasses, the NWS said.

This flash flood warning is in effect until 4:30 p.m.
