Details: 
...FLOOD WATCH FOR SNOWMELT IN EFFECT FROM WEDNESDAY AFTERNOON THROUGH WEDNESDAY, MAY 29...

* WHAT...Flooding caused by snowmelt is possible.

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

* WHEN...From Wednesday afternoon through Wednesday, May 29.

* 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 in low lying areas on the east side
of Fort Yukon from the middle to the end of week, with possible
flooding developing over the weekend. This will be a slow-onset
flood, then slow to recede event.

* ADDITIONAL DETAILS...
- Breakup is underway on the Porcupine River east of the border
with high water levels due to snowmelt from a much wetter
than average winter. The Porcupine River below Old Crow
(Canada) crested at 53.56 ft on May 19, while the Porcupine
River gage closer to the US border had a record crest of
53.57 ft on May 19. This high water will likely reach Fort
Yukon by midweek, at which point the Porcupine may cause the
Sucker River to back up into low-lying areas on the east side
of town, then spread through the swales westward. Based on
historic norms, if flooding occurs, expect floodwaters to
slowly peak on the weekend, then slowly recede next week.
There is potential for this event to be very similar to
flooding last year; however water levels on the Yukon River
are not
nearly as high as last year which could mitigate the
situation.
