ESFBOI
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 Sunday afternoon.
Continue to monitor the latest forecasts and river forecasts from
the National Weather Service.
* WHAT...Southwest winds 20 to 30 mph with gusts up to 50 mph

Monday morning.
ESFPDT
Synopsis: An atmospheric river will bring abundant moisture to the
region with an incoming system Sunday through Monday. Rainfall
amounts of 1 to 2 inches are expected along the Oregon and
Washington Cascade crest and in the higher mountains of northeast
Oregon and southeast Washington. These amounts may be increased
locally by 1 to 2 inches of snow melt from what remains of the high
mountain snowpack.
Where: The East Slopes of the Washington and Oregon Cascades, The
Northern and Southern Blue Mountains, The Blue Mountain Foothills of
Washington and Oregon, Wallowa County and the Grande Ronde Valley.
When: Rain will arrive along the Cascades early Sunday morning and
in the eastern mountains late Sunday morning and afternoon. Rain
will taper off Monday afternoon and evening.
What: The precipitation and possible snow melt will lead to rises on
area creeks, streams and rivers. Rivers are low enough that only the
Naches River at Cliffdell and the Naches River at Naches are
expected to reach bankfull Monday and only by a few inches at those
locations. However, with the heavier periods of rain rapid rises
will be possible on smaller streams and creeks, especially in
Wallowa County and this is the main concern for the next couple of
days.
An update will be provided Sunday morning.
