   Summary Author:  Timothy Wenzel

    Great Lakes gales are often referred to as the  Witches of
   November. They’re caused by intense  low pressure drawing very cold
   air down from Canada, over the relatively warm  Great Lakes,
   creating almost  hurricane-like conditions. A tragic example was the
   sinking of the  Edmund Fitzgerald on November 10, 1975.
   Approximately 6,000  shipwrecks lie at the bottom of the Great
   Lakes, many from unfortunate encounters with forceful, late autumn
   gales.
   The white caps in this photo on  Lake Michigan were generated by a
   classic northwest  gale that began building waves in the morning
   hours of November 1, 2020. By 3:00 p.m. significant  wave heights
   (crest to trough) approached 13 feet (4 m). Winds gusts exceeded 45 mph
   or about 40 kts.  Click here to see a 4x slow-motion video that
   nicely illustrates the sheer power of these waves.
