Storm tracking symbols
The weather application uses a range of symbols to
represent different types of storm tracks. The storm
tracking function enables you to monitor signicant
storms in the area.
Examples of signicant storms include tropical
disturbances, depressions, storms and cyclones,
hurricanes, typhoons, and super typhoons.
The weather map displays the track that the storm
has taken, its current and forecasted position, the
wind radii (current position only), direction, and
speed of travel.
Storm tracks are highlighted on the weather map in
the form of symbols, as shown below.
