...FLOOD WATCH FOR SNOWMELT REMAINS IN EFFECT THROUGH WEDNESDAY
AFTERNOON...

* WHAT...Flooding caused by snowmelt continues to be possible.

* WHERE...Rivers and creeks draining the Brooks Range including
  areas around Atigun Pass, Galbraith Lake, and The Dalton Highway
  from Mp 232 To Mp 356, the Central Arctic Plains, Central Beaufort
  Sea Coast, Eastern Beaufort Sea Coast, and Western Arctic Plains.

* WHEN...Through Wednesday afternoon.

* IMPACTS...Rapid snowmelt and ice jams could lead to flooding of
  rivers and streams across the North Slope. Access to roads,
  airstrips, and low-lying infrastructure may be affected. High
  flows could lead to bank erosion that could threaten nearby roads.

* ADDITIONAL DETAILS...
  - Rivers are continuing to breakup across the North Slope.
    River levels are beginning to crest and gradually dropping
    along the middle parts of the Sag, Kuparuk and Colville
    Rivers. On the Sag, there has been an emergency closure of
    the Dalton Highway between MP 305 and MP 356 due to a major
    washout at MP 315 caused by a failed culvert as well as water
    over-topped the road at several other spots. On the Colville,
    flooding is occurring at Umiat with ice jams present farther
    downstream. Flooding could occur downstream over the next
    couple of days as these ice jams release.
