Areas of concern are between Nome and Council, particularity streams
and rivers draining the south aspects of the high elevation terrain
of the Seward Peninsula.
Rivers and streams in the Nome and Council area are already high
following rainfall over the weekend and early this week. Around 0.25
to 0.50" of additional rain is expected by the end of the week which
will keep water levels high. No flooding is expected but those along
the rivers and streams should be vigilant of the high water that is
expected through the end of the week.

Low pressure begins to dig southward from the PACNW on Friday,
tapping into a fetch of Pacific moisture that will evolve into an
atmospheric river streaming into the Desert Southwest this weekend.
Showers and thunderstorms develop on Friday and Saturday across the
region. Lighter rainfall totals Friday and Saturday will reflect,
initially lower, moisture. However, a few thunderstorms could produce
impactful downpours on saturated soils left over from last weekend's
historic rainfall.
Deeper moisture develops Saturday night and early Sunday. This is
expected to produce heavier and more widespread rainfall across
southeast UT and southwest CO Sunday and Monday, mostly below 10000
feet. While rivers are forecast to remain below action stage, a
growing concern lies in the potential for runoff around saturated
hillsides in the region. This could produce rock, mud, and debris
flows onto roadways, as well as flash flood prone burn scars, washes,
slot canyons, and arroyos. Early estimates predict an area of 1 to 2
inches of new rainfall for portions of southeast UT and southwest CO.
This is a preliminary forecast that hinges on slight shifts in a
strong moisture plume impacting the region. It also attempts to
capture the most statistically likely outcome, despite stronger and
weaker outlier predictions. Outdoor enthusiasts, motorists, and
residents of recent flood impacted areas are encouraged to remain
abreast of the developing forecast in the coming days.
