Map layers can be combined to support dynamic weather data analysis. Layers are organized into groups for easier discovery and context. Only one layer group can be active on the map at a time, but the Severe Weather group can complement any selected group.
Managing map layers
On the map, select Map Layers.
The Map Layers pane opens.
Enable the group that you want to view.
The available groups are:Severe weather
General weather
Wind
Air quality
Climatology
In the group, enable or disable individual layers as needed.
Only one layer group can be active at a time. The exception is Severe weather, which you can use together with any other group.
The Severe Weather group can be switched on or off to add critical weather context to your analysis.
To close the Map layers pane, select X.
The pane closes, and the legends for the selected layers stay on the map.
