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 significant storms in the area.
Examples of significant 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.
Description
Lightning — a lightning symbol is
shown at each cloud-to-ground strike:
• Light (recorded in last 10–15
minutes.)
• Medium (recorded in last 5–10
minutes.)
• Dark (recorded in last 0–5 minutes.)
More recent strikes are overlaid over
older symbols.
Wind — Wind symbols show the
current wind direction and strength
and can be displayed as either an
arrow or a wind barb. Wind arrows
indicate speed — the larger the arrow,
the greater (stronger) the wind speed.
Wind barbs give a more precise
indication of wind speed as shown in
the wind speed symbols section.
Sea surface temperature (green,
yellow and orange)
• Blue — coldest
• green

Surface observation stations (pink)

can be viewed at surface observation
stations. Not all data is available for

you to access details of city weather
forecasts. Up to 3 forecasts are
displayed for each city.
