Inhabitants of Norway could notice a haze in the air, heavily reducing visibility in some areas. In some areas the haze was so heavy that it blocked out the sunlight, appearing to be fog.
Several cities in Norway have given a red air quality warning (second highest), including Ålesund, Trondheim, Drammen and Bergen.
According to the Meteorological Institute in Norway the reason for the haze is because of particles from agricultural areas in Eastern Europe.
“The dust particles are blown up from dry agricultural areas and the powerful eastern wind takes it with it over the mountains, and then they fall down on the West country” says State meteorologist John Austerheim to NRK.
The high levels of particles in the air meant that people at risk, with for example Asthma should keep indoors if they notice any negative effects.
Norway is currently experiencing a strong south-eastern wind which has brought in unusual warm air for the season and is responsible for bringing the dust particles to the country.
Normally the wind blows in from the West and the Northern Sea, bringing colder air.
