Meteoalarm.eu - to everyone interested in European weather
Meteoalarm is a website that informs public and authorities about severe weather conditions in 33 European countries.
On meteoalarm weather symbols and colour-coded maps of Europe show at a glance where the weather might be, or soon become, dangerous.
Meteoalarm an initiative by EUMETNET, the public European weather services network within the World Meteorological Organization.
Finnish Meteorological Institute provides information to Meteoalarm for Finland.
The danger of a weather phenomenon and its impacts to society are described by four colour-coded awareness levels.
The awareness level is green when no particular weather awareness is needed over land.
The awareness level is yellow when the weather is potentially dangerous. The weather phenomena that have been forecasted are not unusual, but be attentive if you intend to perform activities that may expose you to meteorological risks. Keep informed about the expected meteorological conditions and do not take any avoidable risk.
The orange awareness level means that the weather is dangerous. Unusual meteorological phenomena have been forecast. Damage and casualties are likely to happen. Be very vigilant and keep regularly informed about the detailed expected meteorological conditions. Be aware of the risks that might be unavoidable. Follow any advice given by your authorities.
The red awareness level means that the weather is very dangerous. Exceptionally intense meteorological phenomena have been forecast. Major damage and accidents are likely, in many cases with threat to life and limb, over a wide area. Keep frequently informed about expected meteorological conditions and risks. Follow orders and any advice given by your authorities under all circumstances. Be prepared for extraordinary measures.
Weather symbols illustrate the type of severe weather.
