“The Forest Service is working on rehabilitation of the fire area on Mt. Adams, however, the big concern with the predicted rains is for public safety,” said District Ranger, Nancy Ryke. “We want to let people know debris flows are a real possibility.”
Rehabilitation Team Hydrologist, Tom DeRoo said from his experience the predicted rains may be enough in a short enough time to create landslides. “This is the kind of storm that can trigger debris flows down channels anywhere around the mountain depending on where the rain goes.” DeRoo said. “This can happen whenever it rains like this, unrelated to the fire.”
He said the most affected drainages will be Cascade, Morrison, Salt and Crofton creeks, along with any of the major drainages around the forest. “Downstream, there is the possibility of a muddy flood in the White Salmon and other rivers,” he continued.
Weather forecasts call for 2.4 inches of rain in a 24 hour period from Sunday night through Monday, Oct. 15, 2012. Though the fire area closure order for the entire Mt. Adams Wilderness is still in place, people using areas around Mt. Adams or any other steep drainage on the Gifford Pinchot National Forest and Mount St. Helens National Volcanic Monument should be aware of potential landslides and flooding.
