Varningar, Nunamuit Mountain

Special Weather Statement issued June 10 at 4:47AM AKDT by NWS Fairbanks AK Sunshine and relatively warm temperatures continue over the N Slope and Brooks Range, with snowmelt continuing along with gradual rotting of river ice. Ice jams have progressed downstream past Horseshoe Bend, with water levels increasing around Horseshoe Bend. A small ice jam has formed at the Itkillik River confluence four miles upstream of Nuiqsut. Water levels on the Kuparuk River near Deadhorse have risen to within moderate flood stage at 37.8 feet due to a likely ice jam downstream of the gage near Deadhorse. Water levels in the Colville River at Umiat have increased by 1 foot since yesterday with the flood stage approaching action stage. The Sag River at Pump Station 3 is also experiencing higher water levels with it crossing action stage of 19 ft and heading toward minor flood stage of 20ft. These increased water levels are projected to continue to move downstream in the coming days. These water levels could potentially continue to rise into the workweek. With the relatively warm temperatures expected to continue, we could see gradual snowmelt leading to further increasing water levels on the Colville River, Kuparuk River, and the Sag River along with the ice jams.
