Weather Data Broadcasts
Weather data is broadcast at different intervals for each weather feature. For example, radar is broadcast at
five-minute intervals. When the Garmin receiver is turned on, or when a different weather feature is selected, the
receiver must receive new data before it can be shown. You might experience a delay before weather data or a
different feature appears on the chart.
NOTE: Any weather feature can change in appearance if the source that provides the information changes.
Weather Warnings and Weather Bulletins
When a marine weather warning, weather watch, weather advisory, weather bulletin, or other weather statement
is issued, shading indicates the area to which the information applies. The aqua lines on the chart indicate the
boundaries of marine forecasts, coastal forecasts, and offshore forecasts. Weather bulletins may consist of
either weather watches or weather advisories.
To view information about the warning or bulletin, select the shaded area.

and colors. Precipitation is shown either independently or with other weather information.
Select Charts > Precipitation.
The time stamp in the upper-left corner of the screen indicates the elapsed time since the weather data
provider last updated the information.
Storm Cell and Lightning Information
Storm cell are represented by the icon on the weather precipitation chart. They 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 lines in each cone indicate where the storm will most likely be in the
near future. Each line represents 15 minutes.
Lightning strikes are represented by the icon. Lightning appears on the weather precipitation chart if strikes
were detected within the last seven minutes. The ground-based lightning detection network detects cloud-to-
ground lightning only.
