A weather warning for freezing fog patches has been issued by the Met Office.

A yellow warning of fog comes into affect at 5pm today and could last through Thursday morning.

Driving conditions will be difficult with journeys likely to take longer than usual whilst some delays to air travel are possible, a Met Office spokesman said.

The Met Office's chief forecaster said: "A few patches of fog will persist during Wednesday afternoon across East Wales, the Midlands and eastern England, then reforming or thickening up over these areas quickly during the evening and more widely across the rest of the warning area overnight and into Thursday morning.

"Whilst not all areas will have fog, where it does form the visibility could be less than 100 metres.

"Combined with temperatures below freezing, there is also the risk of ice forming on some untreated surfaces particularly later in the night and early on Thursday morning.

"The fog patches are expected to slowly thin during Thursday, although some patches may persist throughout the day - most likely in a zone from the West Country to Eastern England."
