The system of storms moving through southwest and central Idaho Tuesday morning has led the National Weather Service to issue a flash flood warning for portions of Boise and Valley counties — with an special warning for motorists who plan on using Idaho 55 to go between Boise and McCall.

Those thunderstorms have raised the risk of erosion around the area burned by the Springs Fire earlier this summer. That means there is a high risk of mudslides and rocks and boulders falling on to Idaho 55, especially in the areas between Banks to Smith’s Ferry. The same risk exists along the Banks-to-Lowman highway between Banks and Crouch, as those were areas burned by the Springs Fire earlier this summer, according to National Weather Service reports.

The cold front moving through Southwest Idaho Tuesday morning has brought a significant amount of moisture to the mountain areas, with some thunderstorms, according to National Weather.

As of 10 a.m., Boise County Sheriff’s dispatchers said there were no reports of mudslides but there were reports of a few rocks falling on to both highways.

The rain is expected to stop by later Tuesday afternoon.
