...FLOOD WATCH FOR SNOWMELT IN EFFECT THROUGH TUESDAY 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 322, the Central Arctic Plains, Central Beaufort
  Sea Coast, Eastern Beaufort Sea Coast, and Western Arctic Plains.

* WHEN...Through Tuesday 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...
  - Flooding is likely across portions of the North Slope due to
    an unusually deep and persistent late-season snowpack
    combined with a sharp and prolonged warming trend through
    next week. A rapid onset of snowmelt has begun as
    temperatures have warmed into the 50`s and 60`s over the past
    couple of days across the North Slope and are expected to
    remain well above average through the middle of next week.
    River levels have begun to rise and will likely crest early
    next week. Ice has begun to breakup on the upper part of the
    Sag River on Thursday with DOT reporting water over a portion
    of the Dalton Highway near MP 323. Reports also show that the
    Colville River is beginning to breakup, though no impacts
    have been reported yet. Intact ice remains on many of the
    larger rivers, and the sudden influx of snowmelt runoff could
    lead to ice jam formation. These jams can cause sudden and
    severe rises in water levels, posing a significant threat to
    roads or other infrastructure near the affected waterways.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

take action if a warning or advisory is issued, or flooding is
observed.

Stay tuned to further developments by listening to your local radio,
television, or NOAA Weather Radio for further information.
