...FLOOD WARNING FOR SNOWMELT REMAINS IN EFFECT UNTIL 4 PM AKDT
FRIDAY...

* WHAT...Flooding caused by snowmelt continues.

* WHERE...Colville near Umiat To The Mouth Of The River.

* WHEN...Until 400 PM AKDT Friday.

* IMPACTS...High water from rapid snow melt and recent ice jams is
  leading to significant flooding along the Colville River.

* ADDITIONAL DETAILS...
  - At 158 PM AKDT, Monday morning, water levels at the USGS
    Colville River gage at Umiat were at 62.94 ft and still
    rising. This is the highest on record by over 3 ft since the
    gage was established in 2003.

    Water has now inundated portions of the Umiat airstrip and is
    encroaching on structures in the camp.

    High water extends downstream to the Colville River Delta
    where several ice jams have formed over the previous 24-hrs,
    leading to flooding of the eastern floodplain.

    Once these ice jams release, communities and infrastructure
    downstream should prepare for and expect high water and
    flooding over the next couple of days.

    Water levels are expected to continue to slowly rise and
    level off through the end of the week as additional high
    elevation snow melt is expected to make its way downstream.
