June is often a fairly wet month in Idaho, which is mostly an arid or semi-arid state. The end of May and continuing into June has brought a lot of precipitation into southern, south central and southeast Idaho. Much of it is in slow moving thunderstorms. Thunderstorms are much more typical of July and August than May in Idaho.
In 2007 over a million acres of wildfire burned in Idaho’s mountains (and even more on its sagebrush steppe country — “rangelands”). The soil on the burns on these steep mountains are stable yet as this mudslide west of Ketchum indicates.
When travelling backcountry roads you should inqure about slides and washouts, and at least for the next week (according to the weather report) be prepared for flash floods.
