Description:
ESFBOI
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, and high terrain in southwest
Idaho.
Burn scars have the highest risk for flash flooding. Several burn
scars across the area including the Wapiti burn scar near Grandjean,
ID, the Fox 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 are of particular
concern for flash flooding and debris flows. Please monitor the
latest weather conditions if traveling near these areas.
