WINTHROP — A flash flood watch is in effect for the Methow Valley until noon Saturday due to forecasted heavy rains.
One to three inches of rain is possible near the Cascade crest into the upper Methow Valley. The advisory includes burn scars from the Cedar Creek and Cub Creek 2 fires, according to the National Weather Service.
Burned areas are more vulnerable to debris flows.
A recently completed Burn Area Emergency Response report, which assesses damage following a fire, found several areas within the Cedar Creek Fire have a “high probability of experiencing a debris flow” if a storm produces about a third of an inch during a 15-minute period. This includes watersheds along Highway 20 roughly between Lone Fir Campground and the Cedar Creek Trailhead.
Similarly, burn scars within the Cub Creek 2 Fire near Eightmile Creek, Falls Creek, and the main stem of the Chewuch River have a high probability of experiencing debris flow, the report said.
