XM WX Weather Features
Following is a brief description of each weather feature. The weather features are divided into three subcategories: Precipitation, Atmosphere,
and Sea State.
Precipitation
The Precipitation category provides NEXRAD/Cloud Top, Storm
Cell, Lightning, and Hurricane data. Each feature can be turned on
or off, or set to display at a selected zoom range.
NEXRAD
NEXRAD is an acronym for NeXt Generation Weather RADar. The
NEXRAD feature displays precipitation, from very light rain and snow
up to strong thunderstorms, in varying shades and colors.
A legend
showing the colors for Rain, Mix, and Snow can be displayed by
pressing the ADJ key and selecting Weather Legend. NEXRAD
can be displayed independently or with Cloud Tops.
