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
• yellow
• orange and red — warmest
Surface observation stations (pink)
— Current or historical weather
data can be viewed at surface
observation stations. Not all data is
available for all stations.

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