Temperature & Precipitation, Dec. 2016 - Feb. 2017
Several areas saw above normal precipitation during winter 2016-17 including the northern half of Alaska, the majority of the Yukon and the northern region of the Northwest Territories. Areas further south including south-central Alaska experienced a drier than normal winter. In terms of temperatures, the North Slope, northeastern British Columbia and the entirety of the Mackenzie Delta experienced significantly higher than normal temperatures this winter. These milder than normal conditions are explained by a rather persistent southerly circulation of air along the eastern side of the Rockies throughout most of the winter. Temperatures over the majority of Alaska and the Yukon were close to normal except for the area between King Salmon and Gulkana, AK which experienced colder than normal conditions. Despite near normal temperatures in Dawson, YK this winter, warm conditions in November reduced ice buildup preventing the unofficial ice road crossing the Yukon River from remaining open.
