For every sudden or significant change in the air pressure, the weather
icons will update accordingly to represent the change in weather. If the
icons do not change, then it means either the air pressure has not
changed or the change has been too slow for the intelligent weather
station to register. However, if the icon displayed is a sun or rainy, there
will be no change of icon if the weather gets any better (with sunny icon)
or worse (with rainy icon) since the icons are already at their extremes.
The icons displayed forecasts the weather in terms of getting better or
worse and not necessarily sunny or rainy as each icon indicates. For
example, if the current weather is cloudy and the rainy icon is displayed,
it does not mean that the product is faulty because it is not raining. It
simply means that the air pressure has dropped and the weather is
expected to get worse but not necessarily rainy.
The change of weather forecast icon is in agreement with the
relationship between current relative pressure and the pressure change
in the last three hours.
If the weather is changing, both old weather icon and new weather icon
will be shown with a weather tendency indicator (animated arrows). If
the weather has not changed within 6 hours, only the new weather icon
in the middle display will be shown.
