Storm Cells
The Storm Cells feature displays storms as well as the storm’s projected path in the immediate future.
Marine and Automotive units also show the size of the storm cell. The direction of the red cone indicates the projected path of the
storm cell. The red bars that appear in the cone indicate where the storm will be in the future. Each bar represents 15 minutes.
Aviation units show the direction of the storm with an arrow. The tip of the arrow indicates where the storm should be in
15 minutes. Critical information about the storm cell can be viewed by selecting the storm cell with the map pointer.
