The Yukon River at Ft. Yukon broke up Tuesday with minor flooding.
The breakup front remained stalled at 6 Mile Island below Ft. Yukon
as of Thursday afternoon. Water levels remain low upriver.
The ice between Fort Yukon and Beaver is slowly degrading, with
water levels rising Wednesday night into Thursday at Beaver. Beaver
is expected to slowly break up Friday through Sunday. The timing of
the breakup front reaching Stevens Village and the Dalton Highway
bridge could be anywhere from 1-5 days. This hydrologic outlook will
expire at noon on May 10 and not be continued unless there is a
change in breakup progression.
The Porcupine River has not started to break up in Canada.
Increasing flows are not expected for at least seven days at Fort
Yukon.
