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.
