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 five 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.
