The chart above is an easy reference for pilots to assess where conditions are VFR, Marginal VFR or IFR.
The station circle is colour coded as follows Red=IFR, BLUE=Marginal VFR, BLACK=VFR.
Remember, this is a report of actual weather conditions NOT a forecast. Each observation shows the amount of cloud observed, the wind direction (from which the wind is coming), wind speed (1 barb=10 knots, half a barb=5 knots), Temperature (top left), dew point (bottom left), weather, visibility in metres (central left) and ceiling in 10's of feet, i.e. L7-700ft.
