...ATMOSPHERIC RIVER WILL BRING MODERATE RAINFALL LEADING TO RISES
ON STREAMS AND RIVERS...

Synopsis: An atmospheric river in the Pacific is bringing abundant
moisture to the region. Storm total rainfall amounts in the Outlook
area range from 1" in valleys to 2" on ridges. Rainfall amounts
underestimate flood potential as snowpack melt will add snow-water
equivalent contributions of around 2".

Where: Elkhorn and Wallowa Mountains in Oregon. Adams, Washington,
northern Gem, Valley, Boise, and northern Elmore counties in Idaho.

When: Rainfall beginning Sunday evening and ending Monday evening.
Rain will expand from NW to SE in the first few hours.

What: Moderate rainfall leading to rises in creeks, streams, rivers,
and lakes. Rainfall could be locally heavy Monday morning and Monday
afternoon/evening as terrain driven storms become more likely
leading to potential for minor flooding. Potential for mud or
rockslides.

The next update will be provided early Sunday morning.
