Meteoalarm.eu - to everyone interested in European weather

Meteoalarm is a website that informs public and authorities about severe weather conditions in 36 European countries.

www.meteoalarm.eu is a website where you are able to see in one glance where in Europe weather is or might become dangerous. The danger of a weather phenomenon and its impacts to society are described by colour-coded awareness levels. Colour coding is harmonized among the Meteoalarm member countries so that e.g. orange colour indicates same level disruption and potential danger caused by severe weather, both to the society and to you, no matter in which of the 36 Meteoalarm countries you happen to be in.

When more than one warning is in force in the same region, colour of that region indicates awareness level of the most severe weather event in that region. Pictograms show you what types of weather are expected to cause disruption and potential danger. By clicking on a region you will find more detailed information about expected time period and intensity of the event, and in some cases also recommendations for actions.

Meteoalarm is an initiative by EUMETNET, the public European weather services network within the World Meteorological Organization (WMO)

Information in www.meteoalarm.eu is provided by each country's National Public Weather Service. Severe weather information for Finland is produced by Finnish Meteorological Institute (FMI)

Colour-coding of the 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.

Meteoalarm forecast period for Finland

Weather warnings in Finland are valid 24 hours. For example, a forecast issued today at 1 pm is valid until tomorrow 1 pm. On Meteoalarm the awareness level information is presented separately for two days, i.e. for today and for tomorrow. The awareness level information for the first day (Today) always originates from FMI's 24 hour warnings. The second day (Tomorrow) information is combination of the 24 hour warning and Early warnings. The colour code visible in the map is determined by the event with highest awareness level that day.
