...FLOOD WARNING NOW IN EFFECT UNTIL NOON AKDT MONDAY...

* WHERE...Koyukuk River near Allakaket.

* WHEN...Until noon AKDT Monday.

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

* ADDITIONAL DETAILS...
  - Since Wednesday the Koyukuk River has been inundating roads
    in downtown Allakaket

  - River levels appear to have stabilized, but inundation of low
    lying roads is expected to continue.  The streamgage on the
    Koyukuk River below the John River has shown over a foot of
    water level drop in the last 12 hours. The Middle and South
    Forks of the Koyukuk are also showing decreasing water
    levels. Water levels at Allakaket should start showing a slow
    recession late this evening.  This is encouraging as over and
    inch of rain is forecast for the south slopes of the Brooks
    Range through Tuesday.  For context, the highest water levels
    from this event are about 7 ft lower in Allakaket than the
    1994 flood.
  - Low lying roads are currently flooded and airport access may
    be cut off.
