Weather warning for fog across Devon

The Met Office has issued a severe weather warning for fog across Devon.

The Exeter-based agency says patchy fog is likely to form during this evening and the first part of the night, with smoke from bonfires potentially increasing the risk of visibility falling below 100 metres in some places for a time.

Road users are urged to be aware of the risk of localised and sudden deteriorations in visibility.

Increasing cloud and wind will help to clear any dense fog later in the night.

The Met Office's chief forecaster said: “A ridge of high pressure will affect much of the UK during Wednesday evening and first part of the night, with clearing skies allowing a sharp fall in temperature and the development of patchy fog and even some freezing fog.

“Smoke from bonfires will also become trapped near the ground increasing the risk of localised poor visibility and increasing the risk of fog development particularly on low lying ground.

“The fog risk will increase further east across England later in the night and the requirement for further warnings will be kept under review.”
