High pollution episode warning: First summer-smog of 2011

News published: 21/04/2011

The high pressure system persisting over the UK is forecast to bring warm and still conditions to the UK over the Easter weekend. These conditions mean it is likely that the UK will experience a high pollution episode this weekend.

Elevated levels of PM10 and ozone reaching high or moderate are expected from now until at least Sunday. The forecast is therefore for high pollution for PM10 and ozone across England and Wales, and low for other pollutants over the weekend.
