THICK fog is causing delays for many drivers across the South this morning.

The Met Office has issued a yellow warning for fog, with visibility as low as 100 metres in some places, causing tailbacks on many of Hampshire’s roads.

Chris Burton, from forecasters MeteoGroup, said: “The fog is quite extensive across much of England and Wales this morning, and quite a few places will be waking up to quite foggy conditions.

“But as we go through the morning the fog and cloud should break up, and by afternoon we should see some good spells of sunshine.”

Commuters are advised to take extra care when travelling.
