This morning’s reading is one of the coldest recorded in recent weeks and is much lower than the typical weather for Watson Lake. While the average overnight low for February usually stays between minus 19 and minus 27 degrees, this latest drop is a significant change from the norm.

The freezing weather also affects travel at the Watson Lake Airport, which operates 24 hours a day. The extreme cold can make it difficult for small airplanes to fly and creates challenges for crews working to keep the runway and surrounding areas clear of snow.
