Understanding Hurricane Information

The Hurricanes feature shows the current position of a hurricane, tropical storm, or tropical

depression, as well as its projected path (indicated by a red line). The darkened dots that appear

along the red line display the projected locations received from the National Hurricane Center. The

center provides four forecasts at 12-hour intervals (12 Hrs, 24 Hrs, 36 Hrs, and 48 Hrs), as well as

the current conditions (Now).

Understanding Marine Warnings

When a Marine Warning is issued, the area for the warning is highlighted in red. To view

information about the warning, select the warning area. The light blue lines on the chart indicate

marine weather warning zones.
