AIR pollution in South London has risen to high levels due to the UK heatwave.

The London Air Quality Network is reporting that the high levels of air pollution could continue across today with thunder showers predicted for tomorrow.

The network is encouraging those with conditions such as lung and heart problems, along with asthma, to reduce the amount of physical exertion they go through.

It has been advised that anyone experiencing discomfort such as sore eyes, cough or sore throat should consider reducing activity, particularly outdoors.

A spokesman said: "The weather is set for another fine day turning hot to very hot by late morning and continuing into the evening with sunshine and light winds.

"Ground level ozone production is also expected to continue in these conditions.

"Cloud is forecast for mid afternoon, with some thundery showers possible.

"Light winds from the continent are expected along with ozone and particulate import from this region.

"High levels of ozone are possible along with possible Moderate particulate levels.

"Thursday is still set to be very warm, but with a slight reduction in temperatures reaching the high twenties.

"There is a stronger possibility of thundery showers later in the afternoon.

"Easterly light winds are forecast along with pollution import from the continent as seen of late. This together with the production of ground level ozone is likely to result in 'moderate' levels of ozone and particulates.

"This forecast is intended to provide information on expected pollution levels in areas of significant public exposure. It may not apply in very specific locations close to unusually strong or short-lived local sources of pollution."
