Alaska's wild winter has been relentless, with yet another hurricane-strength blizzard smacking the state yesterday (Feb. 14).
The lower 48 states have had an unusually mild winter, but Alaska has been buried under snow and shivering in frigid temperatures.
Temperatures in some towns have dipped to a whopping 30 degrees below average for this time of year. So much snow had fallen in the town of Cordova in January that Alaska's National Guard had to help dig residents out. The tiny village of Nome needed an emergency shipment of fuel after its final shipment for the winter was blown off course by another fierce storm.
A climate pattern known as the Pacific Decadal Oscillation is influencing this wicked winter, as it tends to keep Alaska cooler than normal. La Niña, a cooling of the waters of the equatorial Pacific, has also been in play, and it also typically creates colder temperatures for Alaska.
