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.

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.
NOTE: This feature is not available on all devices and in
all subscriptions.
Hurricane Information
The weather Precipitation chart 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 weather data provider.

The Forecast chart shows city forecasts, marine forecasts,
