XM WX Satellite Weather
A Garmin XM satellite weather receiver and antenna receives XM WX Satellite Weather data and shows it
on the chartplotter. The weather data for each feature comes from reputable weather data centers such as the
National Weather Service and the Hydrometerological Prediction Center. For more information, see the XM
WX Satellite Weather Web site at www.xmwxweather.com.
Weather Data Broadcasts
Satellite Weather data is broadcast at set intervals. For example, XM weather radar data is broadcast at ve-
minute intervals. When the Garmin receiver is turned on, or when a new feature is selected, the receiver has to
receive new data before it can be shown. You might experience a delay before weather data or a new feature
appears on the chart.
: Any weather feature can change in appearance or interpretation if the source that provides the
information changes.

Precipitation is indicated ranging from very light rain and snow, up to strong thunderstorms, in varying shades
and colors. The time stamp in the upper-left corner of the screen indicates the elapsed time since the weather
data provider last updated the information. Precipitation is shown either independently or with a variety of
other weather information.
