ESFAFG The Yukon River continues to hold sections of thermally degraded in-place ice between Ft. Yukon and Tanana. These sections are slowly breaking up and will continue to create ice runs.

ESFAFG The Koyukuk River is mostly open between Hughes and its confluence with the Yukon River. Upstream of Hughes, in-place ice remains and will continue sending runs of ice downstream as breakup progresses.

ESFAFG The Yukon River is open from Tanana to Anvik. Ice runs from upstream of Tanana continue as ice degrades between Ft. Yukon and Rampart. Intermittent in-place ice remains from Holy Cross down to the breakup front which is currently near St. Mary's. Updates from today's River Watch flights will be available this eve.

A frontal system from the Bering Sea is bringing rain and much cooler air to the area this afternoon. Snow levels will fall to around 1500 feet through the evening with snow expected down to highway level Monday night into Tuesday morning. There is considerable uncertainty as to how much snow will fall. It is likely that areas from Healy to Cantwell on the Parks Highway and from Donnelly to Isabel Pass on the Richardson Highway will see 1-3 inches. Elevated areas will likely see the highest amounts. Precipitation will taper off Tuesday afternoon with significant melting expected Wednesday.

ESFAFG Breakup along the Upper Yukon remains stalled below Ft. Yukon since last Tuesday (May 6). The ice is degrading and breaking up locally but in-place ice remains intermittently below the mouth of the Porcupine River down to the confluence with the Tanana River. With water levels remaining low there isn't much force to push the remaining ice out and it is expected to continue degrading over the next few days.

ESFAFG The Yukon River is open from Tanana to beyond Kaltag. With water levels remaining low, stranded ice remains on banks and in side channels. Above Tanana, from Ft. Yukon to the Tanana River confluence, the river ice remains intermittently intact and very degraded. As this ice begins to move out and water levels eventually rise, ice runs can be expected to continue through the end of the week.

ESFAFG The river ice at Hughes lifted on Friday and is thermally degraded but in-place down to Winthrop Point. Below Winthrop Point the river is a mix of degraded in-place ice on bends alternating with open stretches of water to near the mouth which is open for several miles upstream of the community of Koyukuk.
