Purpose and Benefits
The seminar will introduce participants to key concepts of mid-latitude depressions, offshore highs, and inflow and outflow winds, and their interactions with the geography of the Inside Passage.

This seminar is not intended to teach actual forecasting of large scale weather patterns.  Instead, it will show skippers how to apply the information in weather forecasts and local weather reports, to better understand actual conditions in specific locations on the water.

See below for a high level overview of the course.
