Join Our Two-Hour Chesapeake Thunderstorm Webinar July 26
Attention sailors, powerboaters, paddlers, and anglers! If you missed our three-part webinar on storms over the winter, here’s another chance! SpinSheet will host Mark Thornton of LakeErieWX in a two-hour webinar for all boaters July 26 from 7-9 p.m. called “Chesapeake Bay Thunderstorm Essential Skills.”

Chesapeake Bay boaters understand that thunderstorms can quickly spoil a day on the water. Strong winds, tall waves, lightning, and visibility-limiting rain pose a significant risk to mariners. Just in time for the summer thunderstorm season, this webinar will help reduce your chances of a hair-raising or windswept encounter with a thunderstorm.
The webinar for sailors, powerboaters, and anglers will cover:
- How to use Doppler Weather Radar to monitor the development, evolution, and movement of thunderstorms.
- The different types of thunderstorms and the dynamics that lead to their development.
- How to interpret key weather maps to recognize and predict the large and small-scale weather patterns that promote thunderstorm development.
Cost: $50. Click here for webinar details and to register.
