...HYDROLOGIC OUTLOOK IN EFFECT THROUGH WEDNESDAY AFTERNOON FOR THE
YUKON RIVER...

...Locations Impacted...
Yukon Flats

The Yukon River at Eagle broke up Tuesday morning.  As of 10am the
local breakup front had not yet reached Calico Bluffs.

Aerial observations yesterday found all Yukon tributaries from the
Canadian border to Coal Creek open and creating small areas of open
water where they entered the Yukon. The ice in the same region was
showing signs of weakening.

A flood watch was issued for the Upper Yukon region (Canadian border
to Coal Creek). Ice jams may form as the breakup front progresses
downriver and cause localized flooding.

Downstream of Coal Creek the ice appeared to be stronger (more
white/blue ice) and more remnant snow remained in the low lands.

RiverWatch flights will begin on Wednesday (weather permitting) and
updates on breakup progression will be provided as information is
available.
