WEATHER: Expected heavy rains may cause hillsides burned in the recent wildfires to fail

Clackamas County residents in areas burned by the recent wildfires should be careful to watch for landslides and flooding in the next few days. The National Weather Service predicts heavy rains in the areas where the fires burned protective cover off many hillsides.

"When heavy rains hit those hillsides, they could fail, causing mud and debris to enter creeks and rivers," said Jay Wilson, Clackamas County Resilience Coordinator. "That could increase chances of landslides or flooding downstream or at the bottom of barren hillsides."

Sodden hillsides can flow rapidly, striking with little or no warning at avalanche speeds -- faster than you can run. They also can travel many miles from their source, growing in size as they pick up trees, boulders, cars and other material.

"A heavy rainstorm is also a great reminder of the need for property owners to consider flood insurance," said Wilson. "There's a 30-day waiting period for protection to take effect. Please consider flood insurance immediately."
