Fall 2016 saw near normal temperatures in the central Yukon and northern Northwest Territories. Every other portion of the region was above — or significantly above — normal. This is largely a result of record low Arctic Ocean sea ice. Record warm Pacific Ocean waters contributed to the unrelenting warmth of the coastal regions. Precipitation in southeast Alaska was below normal for the season and at a record low for October. Nearly every station in southeast Alaska had their driest October on record. In northwest Canada, almost all of the Yukon Territory was drier than normal. This is likely due to warm, ice-free water, which provides atmospheric heat and moisture at a time of year when it is typically locked away under ice.

Ice melt in the southern Beaufort Sea is off to an early start in 2016. Historically (1981–2010), ice breakup in the southern Beaufort Sea begins in the first half of June. In 2016, breakup conditions began at the end of April. At the end of May 2016, ice extent in the Beaufort Sea was at a record low for this time of year. These conditions are not normally seen until the end of July or early August. As for the extended outlook, conditions generally point toward "warmer and wetter" for June-September 2016, with some caveats.

This was the second warmest winter of record for Alaska as a whole. Only the winter of 2000–01 was warmer. Download the publication for full details.
