Special Weather Statement issued May 12 at 9:49PM AKDT by NWS Fairbanks AK
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.
