Hydrologic Outlook
National Weather Service Boise ID
223 PM MDT Fri Aug 14 2026
Monsoon moisture will bring a threat of thunderstorms to the region
through Saturday evening for much of the area. High atmospheric
moisture will allow for isolated thunderstorms producing heavy rain
accumulations, leading to an increased threat of flash flooding
especially for the recent wildfire burn scars.
Friday and Saturday have the highest chance for locally heavy rains,
especially near the ID-NV border, Baker County, and high terrain in
southwest Idaho.
Burn scars have the highest risk for flash flooding. Several burn
scars across the area are of particular concern for flash flooding
and debris flows, including: the Wapiti burn scar near Grandjean, ID,
the Fox burn scar near Richland, OR, the Powder River burn scar near
Richland, OR, the Tartar burn scar near Weiser, ID, the Coleman Creek
burn scar near Juntura, OR and the Big Grass Fire burn scar near
Jordan Valley, OR. Please monitor the latest weather conditions if
traveling near these areas.
