White stands for missing information from a particular region.

Anyone who wants to stay healthy would never think of driving through a red light and ignoring the dangers. Whether in summer, winter, spring or autumn; floods, drought, lightning, or forest fires: When red is displayed, it has to be taken very seriously; so, too, at www.meteorisk.info .

Concretely this means: Danger for man and animal due to extreme weather is not just a remote possibility in isolated cases. At red , civil protection services, firemen, Red Cross, Alpine rescue services and other task forces are ready for duty. Devastating damage is possible at any time. On average the red warning level is reached only once a year for one parameter in a mid-sized (5000 km 2 ) forecast area.

It is not without reason that orange has much in common with red. At orange high caution is necessary, but large-scale damage is not to be expected. However, local floods and uprooted trees as well as damage to cars and houses due to strong winds are possible. In some cases orange can mean life-threatening danger.
Therefore, the public is advised to follow any possible warnings announced in the media. Thunderstorms with hail at the orange level can cause serious damage. The level orange also warns of extremely cold or unusually hot weather. Considering recent dry weather that has led to forest fires, it is clear that orange is still a very dangerous level. Any instructions given by the civil protection authorities should certainly be followed.

At yellow the danger is relatively low that extreme weather events could overshadow the coming hours. Nevertheless, there are phenomena at yellow that could cause problems or damage; for example, wind gusts of up to 60 km/hr, relatively heavy rain (that does not, however, cause extensive flooding), high temperatures in summer or icy roads in winter.
If warning level yellow is issued due to large quantities of snow, then there is usually a danger of avalanches in the mountains. This could require changes in tactics and in equipment. More detailed information is provided by avalanche warning services. Also, appropriate clothing for each type of weather, season and excursion is recommended. During longer dry periods, there is a danger of forest fires at warning level yellow, but it is not extreme.

Extreme weather situations are not expected.Green does not mean there will be no strong winds, isolated thunderstorms, snowfalls,and cold or hot days. However, no damage is to be expected at this level. Nevertheless, during local thundershowers one should beware of lighting, even at green level.

During the warninglevel green there can be light snowfalls in cities or in lower-lying areas that could disrupt traffic, due to the fact that many drivers in these regions do not own winter tires.
