149 PM AKDT Fri Sep 4 2026

...HYDROLOGIC OUTLOOK IN EFFECT FROM 4 PM AKDT THIS AFTERNOON THROUGH
SUNDAY AFTERNOON FOR HEADWATER STREAMS OF THE KOYUKUK AND MIDDLEYUKON
RIVER BASINS AS WELL AS THE CHENA RIVER BASIN...


...Locations Impacted...
Goldstream Valley and Nenana Hills-Lower Koyukuk Valley-Central
Interior-Dalton Highway Summits-Eielson AFB and Salcha-Two
Rivers-Upper Chena River Valley-White Mountains and High Terrain

Valley-Nenana-Chatanika River Valley-Fairbanks Metro Area

24 Hour rainfall totals across portions of the Western and Central
Interior have generally been between 0.75 and 1.25 inches due to
widespread moderate rainfall. This is a direct result of an
atmospheric river which continues to focus higher than normal levels
of moisture across the region.

Additional rainfall of .50 to as much as 1.50" inches will be
possible Friday evening through Saturday afternoon as a disturbance
aloft moves through and further interacts with the available
atmospheric moisture. Should this occur, 48 hours rainfall will
coincide with 5 to 10 year return intervals with locations receiving
the heaviest rainfall closer to 25 year return intervals.

While main stem rivers will be able to handle this extra volume of
water, some of the smaller feeder streams and rivers could see near
bankfull to minor flooding conditions. In addition increased stream
flows are expected for the next few days, so anyone planning
recreation activities on or along these waterways should exercise
extreme caution and be on the lookout for rapidly rising water
levels.
