Quite the video/article is posted up on the Weather dot com website, recalling Alaska’s coldest temp of -79.8 F at Prospect Creek in the Yukon Flats region during the winter of 1977 (Take a look at https://weather.com/storms/winter/news/cold-outbreak-valentines-northeast-midwest-south-feb2016). It is highlighting the frigid weekend temperatures that will blast through much of the continental U.S. over the weekend- yet with relief on the way as Arctic oscillation kicks in to make the North Pole winds stronger and stifling the Arctic air cold.
Nevertheless, having a 72 hour kit (one week in Alaska) is important in case of a furnace breakdown, frozen pipes, or any other reason causing a home evacuation. Sadly, fatalities mount up during cold snaps due to carbon monoxide poisoning. This can be caused by people heating their homes with propane/ natural gas stoves without venting when the furnace or boiler malfunctions. Or when flue pipes frost up and impede burnt gasses from leaving the home. In rural Alaska it can happen when for reasons of power outage or just an electric appliance dying, people use camping stoves powered by petrol products without providing proper air exchanges.
