Michigan Skywarn is an online community discussion forum created and operated by certified Skywarn® Storm Spotter Tony Gatlin, made for Michigan Skywarn Storm Spotters, National Skywarn® Spotters and local citizens alike. Visit and join this forum for free to discuss Michigan Skywarn, local severe weather, local storm chasing and more. Skywarn® is a national volunteer program of the National Weather Service intended for people of all ages who are interested in helping to save lives and warn their communities of active severe weather in their area. Although this site was created for Michigan Skywarn Storm Spotters to associate, Skywarn Storm spotting experience is not a requirement to join and take part in our community, nor does one have to be a Michigan resident. All are welcome here. For more information on the Skywarn® program and how you can get involved please visit the National Weather Service Skywarn® Spotters web page by clicking here Skywarn websites are vastly based on localized severe weather and since severe weather is not always in occurrence things can sometimes become slow and boring. For this reason, as opposed to most Skywarn websites we also offer information and discussions in other venues as well such as astronomy, outdoor hobbies and offer an "off weather" topic section to discuss any topics of interest. Feel free to join our community discuss your interests, meet new friends and/or just read up on the latest news and local events.
White Hurricane – November 1913 This powerful November storm is considered to be the worst to strike the Great Lakes region in recorded history. While there were other notable winter storms comparable to this one, this is considered the worst because the lakes were still ice-free and shipping was still going strong, causing much more damage and loss of life on the lakes, especially Lake Huron. Sustained winds across eastern lower Michigan, from Detroit up through the Thumb, reached as high as 60 mph, with recorded gusts over 70 mph. While Detroit only received 4.3 inches of snow, many areas along the Lake Huron shoreline received very heavy snow, with snow drifts of several feet reported. But the most memorable thing about this storm is the extreme loss of life that occurred at sea. At least 235 sailors lost their lives on Lake Huron, due to the sinking of dozens of ships, including 8 large freighters.
