Latest Forecast Summary
Moderate air pollution forecast in Southern and Eastern England, Yorkshire and Humberside and Wales on Wednesday. All other regions Low.
Winds arriving in Southern Regions have originated from Central and Northern European. This could cause elevated background concentrations of PM10 and PM2.5. We currently expect concentrations to be Moderate but there is the potential for elevated concentrations due to poorly dispersed local emissions due to settled weather and low wind speeds. There is the potential to see elevated local emissions in many regions across the UK as they will experience a still, frosty and foggy start tomorrow. We will observe the situation closely and update our forecast as required.
The forecast for tomorrow will be available this afternoon.
We are currently observing winds arriving from Central and Northern Europe which is having an affect on PM10 and PM2.5 concentrations in Southern Regions. This is expected to continue through this week as a stable anticyclone lingers over the UK. This is forecast to cause recirculation of air masses over southern regions of the UK. This could lead to further elevated background concentrations of PM10 and PM2.5 when the elevated background is coupled with poorly dispersed local emissions. We will monitor this situation closely as the week progresses.
