Changing towards drier weather with bright periods.
Your device uses its "intelligent" software to determine by itself
if the trends of the various atmospheric data collected enable a
reliable forecast to be made or not. It informs you on a
continuous basis of the confidence index of the device's own
forecast ranging from 1 to 5.
Index 1: low confidence level
Index 4: highly reliable
When the various data and their trends are inconsistent,
forecasting becomes impossible. Only the last forecast that
is no longer valid will remain on display for your
information. The arrows are lighted on a permanent basis
and of course the confidence index will be set to 0.
Speed of change: the forecasts made by the device are generally
valid for the next 6 to 12h period.
STRONG WIND ALARM
Your EASY METEO is equipped with the WORLD exclusive
system of strong wind alarm.
The windsock flickers when the device detects a risk of gusty
winds within the next few hours.
When this forecast becomes no longer valid, the windsock
remains lit for your information for 6 hours.
FROST RISK
Your EASY METEO is equipped with a new world exclusive
system of frost forecasting.
The snow crystal flickers when the device has detected
conditions likely to result in frost. This forecast is valid for the
next 6 to 8 hours.
In the event of lasting frost, the crystal remains on permanently.
