These spiral-bound cards contain all the weather information people find hard to remember such as Sea Areas, Coastal Stations, cloud systems, how to predict the weather around lows and highs, times of broadcasts and the terms used in broadcasts. With a chinagraph pencil you can fill in details and make predictions, because the companion is laminated to stand up to frequent use. It serves as a great aide-memoire that will fit into your pocket.
