From the Hawaii Tribune-Herald: It’s weather Santa would approve.The Big Island’s two summits are braced for Hawaii’s answer to that proverbial howling nor’easter — with wind gusts of more than 90 mph expected to drive up to a foot of snow hard into the mountain faces by today. Temperatures on the peaks were forecast to dip to a frosty 23 degrees Tuesday night, according to the Mauna Kea Weather Center.Mauna Loa and Mauna Kea were under blizzard warnings Tuesday and today and summit roads were closed as a potent upper atmosphere disturbance geared up to slam the peaks. Bitterly cold wind chills, lightning and blowing and drifting snow were combining to create life-threatening conditions for anyone trying to drive or hike the summit of Mauna Kea, forecasters warned. - See more at: http://hawaiitribune-herald.com/news/local-news/winter-arrives#sthash.9V0pKRdQ.dpuf
Of all the places you have in the United States, I think Hawaii would be about the last place you would expect a blizzard warning.
(and since this is not April Fools Day, I am sure this is a legit warning)
