...FLOOD WATCH FOR AN ICE JAM REMAINS IN EFFECT THROUGH FRIDAY
MORNING...

* WHAT...Flooding caused by an ice jam continues to be possible.

* WHERE...The Yukon River downstream of Mountain Village to the
  Yukon Delta Coast.

* WHEN...Through Friday morning.

* IMPACTS...Ice jams may result in flooding along the Yukon River
  over the Yukon Delta. Low lying areas near Emmonak, Alakanuk,
  Nunam Iqua and Kotlik have potential to flood from today through
  Friday. If an ice jam forms, water could rise rapidly.

* ADDITIONAL DETAILS...
  - The Yukon River broke up to past Mountain Village on Sunday
    May 19. The breakup front will likely reach Emmonak and
    Alakanuk between today and Friday. There is potential for
    flooding in Emmonak, Alakanuk, Nunam Iqua and Kotlik as
    breakup progresses. An observer reported on Wednesday that
    water level has dropped at Mountain Village and ice has
    thinned significantly. An observer at Emmonak reported
    Wednesday morning that water level had come up about 3 ft
    since Tuesday, that ice had shifted, and that ice remains
    intact and strong downstream. The observer at Emmonak
    indicated that the ice level was still well below the bank
    Wednesday morning. With the river ice in the Yukon Delta
    thicker than normal this year, it is more likely that ice
    jams will form as high water comes down river. Satellite
    imagery indicates
    stronger than normal shorefast ice along the Yukon Delta
    Coast which could impede the push of break up ice and lead to
    increased risk of flooding in communities near the coast.

...FLOOD WATCH FOR SNOWMELT REMAINS IN EFFECT THROUGH WEDNESDAY
AFTERNOON...

* WHAT...Flooding caused by snowmelt continues to be possible.

* WHERE...The Porcupine River at Ft Yukon, including the city of
  Fort Yukon.

* WHEN...Through Wednesday afternoon.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  sloughs and other low-lying and flood-prone locations near Fort
  Yukon. High water will begin move into low lying areas on the east
  side of Fort Yukon from the middle to the end of week, with
  possible flooding in Fort Yukon developing over the weekend. This
  will be a slow-onset flood, with the water slow to recede as well.

* ADDITIONAL DETAILS...
  - The water levels along the Porcupine River at Old Crow rose
    dramatically last weekend due to heavy snowmelt and remain
    high. This high water is expected to reach Ft Yukon between
    Thursday and Friday, with water levels peaking at Ft Yukon
    over the weekend. This high water will gradually fill sloughs
    and swales east of Ft Yukon late this week and could bring
    flooding into Ft Yukon this weekend with high water
    continuing into next week.
