The initial weather forecast for the Great Lakes on November 6, 1913 was moderate to brisk winds. On Friday a moderately severe storm was predicted. Soon the warnings became more dire hour-by-hour. Weather forecasting was in its infancy then, and radio communication was not much better. By the time it became clear that a freshwater hurricane of epic proportions was developing, the storm was well on its way to becoming the deadliest in Great Lakes maritime history. Over four days the storm claimed the lives of over 250 sailors.
