Thunderstorms can quickly spoil an outing in many ways—strong winds, large waves, dangerous lightning, hail, or visibility-limiting rain. This 3-part live webinar series will examine the various types of thunderstorms and the ingredients that lead to their formation. The webinar will cover why thunderstorms often ‘pop-up’ late on summer afternoons and why some storms have short life-spans while others persist for several hours. The webinar will also introduce the many readily-available resources for forecasting and monitoring thunderstorms.

The webinar is designed for all boaters who would like to reduce their chances of a hair-raising or windswept encounter with a thunderstorm.


The live webinar combines classroom instruction, case studies, and pop quizzes to create an engaging learning experience.
