...FLOOD WATCH FOR AN ICE JAM NOW IN EFFECT THROUGH MONDAY MORNING...

* WHAT...Flooding caused by an ice jam is possible.

* WHERE...The Yukon River near Circle

* WHEN...Through Monday morning.

* IMPACTS...Residents of Circle should be aware that the breakup
  front on the Yukon river is approaching and expected to reach
  Circle in the near future.  No overbank flooding has been reported
  yet. However, as the breakup front moves downstream towards Circle
  it is likely that small jams will form and release, leading to
  rapidly changing water levels with the potential for minor or
  moderate flooding at Circle.

* ADDITIONAL DETAILS...
  - The ice jam that formed 12 miles up stream from Circle
    remains in place. This ice jam remains firmly entrenched,
    however the ice is showing signs of rot and weakening. While
    this is delaying the arrival of the break up front, it is
    also allowing the flood threat to diminish as some of the
    built up water is passing the jam location. This jam is
    expected to stay in place for the next few days.

    Also, downstream of Circle small sloughs and streams are
    clearing of ice, and the main channel of the Yukon is
    beginning to break up in place. This further reduces the
    flood threat for areas downstream of Circle at least as far
    as Beaver.

    As of 2pm today, 5/10, the Yukon River at Fort Yukon was
    running swiftly against the bank immediately beside the
    community of Fort Yukon. There may be some concern for bank
    erosion and minor damage. Be cautious when walking near the
    river bank in this area.

    Even with a reduced flood threat, people living along the
    Yukon River should remain vigilant until the ice jam threat
    passes.

    As of today, 5/10, River Watch flights for the upper Yukon
    have been demobilized. The watch will remain active through
    Monday at noon. Please report any flooding or other ice jam
    related issues to WFO Fairbanks.
