* 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 continuing to rise and will likely crest
early to middle of this week. On the Sag, there has been an
emergency closure o f 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 topping the road at several
other spots. On the Colville, flooding is occurring at Umiat
with ice jams present further downstream. Flooding could
occur downstream over the next couple of days as these ice
jams release.
