Temperature and Precipitation across Alaska and Northern Canada

Between September and November 2018, Alaska, the majority of the Yukon Territory, and a small portion of northwestern Northwest Territories (NT) experienced warmer than average conditions. Small pockets of below average temperatures were recorded in northern BC and southeastern NT. In contrast, below average temperatures were observed over the eastern NT over that same period (not shown on the map). Total precipitation between September and November 2018 was below average over a small area in northwestern Alaska, and across a band spanning southern Alaska, southern Yukon, and southern NT. On the other hand, above normal precipitation was observed along the coast of the Beaufort Sea extending inland along the Alaska/Yukon border, and over northern eastern British Columbia.

A persistent high pressure system brought warmer and drier than average conditions in Alaska. Unlike the majority of the Beaufort Sea area, the ocean edge in the Tuktoyaktuk area started freezing in October, and water stayed open until the end of November. This is much later than usual for the community, which typically sees freeze up by late September. This was partly due to warmer than average ocean temperatures.
