28 GDL 30A Owner’s Manual
Appendix
Weather and Sea Surface Information
The GDL 30A receives XM Weather Radio data and shows it on your
chartplotter. The weather data for each feature comes from reputable
weather data centers such as the National Weather Service and the
Hydrometerological Prediction Center. (See the XM WX Satellite
Weather Web site at http://weather.xmradio.com/weather for more
information.) Any weather feature can change in appearance or
interpretation if the source that provides the information changes.
XM Weather Radio data is broadcast at set rates (see page 26 for
all weather-related broadcast rates). For example, NEXRAD Radar
data is broadcast at ve minute intervals. When the marine network
is turned on or when a new feature is selected, the GDL 30A has to
receive new data before it can be displayed. For this reason you may
experience a delay before weather data or a new feature appears on
the map.
WARNING: The XM Weather Radio data is merely supplemental and advisory
in nature and is not intended to be relied up on as safety-critical information. You
should always exercise caution and common sense when confronted with severe
weather conditions.
