Wind speeds during the Great Storm
Date: 1913
Credits: Lake Carriers’ Association
No Lake Master can recall in all his experience a storm of such unprecedented violence with such rapid changes in the direction of the wind and its gusts of such fearful speed! Storms ordinarily of that velocity do not last over 4 or 5 hours, but this storm raged for 16 hours continuously at an average velocity of 60 miles per hour, with frequent spurts of 70 and over.
