The four weather icons are Sunny, Partly Cloudy, Cloudy and Rainy. There are also two weather
tendency indicators to show the air pressure tendency between the weather icons.
4.5.3
Weather tendency indicator
The weather tendency arrow is located between the weather icons to show the air pressure tendency
and provide a forecast based on increasing or decreasing air pressure.
The arrow pointing to the right indicates that the air pressure is increasing and the weather is expected
to improve. The arrow pointing the left indicates that the air pressure is decreasing and the weather is
expected to deteriorate.
The weather tendency is based on the pressure change since last six hours. If the weather is changing,
the weather tendency indicator (animated arrows) will flash for three hours, indicating the weather is
expected to change. If the weather conditions become stable and no new weather change conditions
are met, then the arrows will be fixed.
Example 1:
Pressure is decreasing, weather is deteriorating.
Example 2:
Pressure is increasing, weather is improving.

When negative rate of change of pressure is exceeded for 3 hours, the storm warning indicator will be
