Garmin GDL30A User Manual

Following is a brief description of each weather feature. The weather features are divided into three subcategories: Precipitation, Atmosphere, 

and Sea State. 

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 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.
