XM WX Satellite Weather and XM Satellite Radio

XM WX Satellite Weather and XM Satellite Radio

XM WX Satellite Weather

A Garmin XM satellite weather receiver and antenna receives XM WX Satellite Weather data and
shows it on various Garmin devices, including the Navigation chart on a 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.

NOTE: To view XM WX Satellite Weather information, you must have a subscription to XM
WX Satellite Weather, and you must have a Garmin XM satellite weather receiver connected to a
chartplotter.

XM WX Satellite Weather Data Broadcasts

XM WX Satellite Weather data is broadcast at set rates. For example, NEXRAD (NEXt Generation
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 map.

NOTE: Any weather feature can change in appearance or interpretation if the source that provides
the information changes.

Viewing NEXRAD Precipitation Information

The precipitation screen shows NEXRAD radar, storm cells, lighting strikes, and hurricane
warnings. NEXRAD shows precipitation 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 National Weather Service last updated the information.
NEXRAD is shown either independently or with a variety of other weather information.

From the Home screen, select Weather > Precipitation.

Showing an Animated NEXRAD Loop

You can view NEXRAD information as an image of the latest update or as an animated loop of the
latest updates.

From the Home screen, select Weather > Precipitation > Menu > NEXRAD Loop > On.

Showing Cloud Cover

From the Home screen, select Weather > Precipitation > Menu > Cloud Cover > Show.

Storm Cell Information

Storm cell icons on the precipitation screen indicate both the present position of a storm and the
projected path of that storm in the immediate future.

Red cones appear with a storm cell icon, and the widest part of each cone points in the direction of
the projected path of the storm cell. The red bars in each cone indicate where the storm will most
likely be in the near future. Each bar represents 15 minutes.

Lightning Information

Lightning strikes are represented by lightning bolt icons. Lightning appears on the precipitation
screen if strikes were detected within the last seven minutes. The ground-based lightning detection
network detects cloud-to-ground lightning only.

Hurricane Information

The precipitation screen can show the present position of a hurricane, a tropical storm, or a tropical
depression. A red line stemming from a hurricane icon indicates the projected path of the hurricane.
Darkened dots on the red line indicate the projected locations through which the hurricane will
pass, as received from the National Hurricane Center. The center provides four forecasts at 12-hour
intervals (12 hours, 24 hours, 36 hours, and 48 hours), as well as the present conditions (Now).

Indicates a low-pressure center. A low-pressure center is an area where the measured pressure is
lowest relative to the surrounding area. Moving away from a low-pressure center in any horizontal

direction results in increased pressure. Winds ow counterclockwise around low-pressure centers

in North America.
Indicates a high-pressure center. A high-pressure center is an area where the measured pressure

is highest relative to the surrounding area. Moving away from a high-pressure center in any
