UPDATE 20 MARCH: The forecast is improving - levels are expected to fall with moderate or low levels predicted for most of the UK later today, and clearing tomorrow. For the latest forecasts and health advice please visit Defra’s UK Air website
High air pollution is currently (19 March 2015) being measured across a number of regions in England and Wales. This is due to pollution brought in via winds from the continent and particulate matter from a combination of local sources.
Levels are expected to fall later today with moderate or low levels predicted tomorrow as changes in weather conditions lead to the dispersal of pollutants. Levels in London and the South East are already down to moderate and are expected to be reporting lows by tomorrow.
