Class description:

Thunderstorms can quickly spoil an outing in many ways—strong winds, large waves, dangerous lightning, waterspouts, or visibility-limiting rain. This four-hour seminar presented by Mark Thornton of LakeErieWX Marine Weather will examine the various types of Great Lakes thunderstorms and the ingredients that lead to their formation. You’ll learn why thunderstorms often ‘pop-up’ late on summer afternoons and why some storms have short lifespans while others persist for several hours. Mark will also introduce the many readily available resources for forecasting and monitoring thunderstorms.

Designed for all Great Lakes boaters (power and sail) who would like to reduce their chances of a hair-raising or windswept encounter with a thunderstorm, this session combines classroom instruction, case studies, and exercises to create an engaging learning experience.
