The stations are indicated by diamonds on the map. Yellow diamonds indicate stations that we have tested and at that time were producing the data YachtWinds uses and in a format YachtWinds understands. Gray diamonds indicate stations that NOAA said were not producing data when we checked. They may be producing data now (sometimes stations break down and then get fixed). Blue diamonds represent stations that NOAA indicated were good but we could not use for some reason. For example BHBM3 in Boston harbor is producing data but not wind data. When a station is not marked as good (yellow) the reason is shown in the lower left of the screen. Even when a station is not yellow you can usually get the station page and weather forecast.
