...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.

...FLOOD ADVISORY FOR SNOWMELT IN EFFECT UNTIL 4 PM AKDT FRIDAY...

* WHAT...Flooding caused by snowmelt is occurring.

* WHERE...Sagavanirktok River along the Dalton Highway.

* WHEN...Until 400 PM AKDT Friday.

* IMPACTS...Flooding of rivers, creeks, streams and other low-lying
  and flood-prone locations is imminent or occurring.

* ADDITIONAL DETAILS...
  - At 138 PM AKDT, high water from rapid snowmelt over the past
    five days continues to cause erosion and minor flooding along
    the Sagavanirktok (Sag) River, affecting travel conditions on
    the Dalton Highway.
    - Multiple sections of the highway have water near or over
    the roadway, with a significant washout reported at Milepost
    (MP) 15. The Dalton Highway remains closed between MP 305 and
    MP 356. The USGS river gauge at MP 325 has likely reached its
    peak and is now slowly receding. However, water levels are
    expected to remain above flood stage through Thursday.
    - High water will continue to move downstream over the coming
    days. Infrastructure near the river`s mouth, including roads
    and bridges near the Deadhorse/Prudhoe Bay area is already
    being impacted. Water levels in this area are expected to
    gradually rise, particularly around high tide.
    - Motorists and local authorities are advised to monitor
    conditions closely and avoid flooded areas.
