Birmingham weather: Met Office issues advice to drivers as yellow warning for fog in force

A two-day yellow weather warning for fog has been issued in Birmingham and travellers have been warned to expect delays on the roads, trains and planes. The warning is in place from 9pm on Thursday (December 1) until 10am on Friday (December 2).

The Met Office warned fog could cause severe disruption to road transport when the visibility falls below 50m, with delays to bus and train services possible and the chance of delays or cancellations to flights. The Met Office also advised people  to avoid driving until the fog clears if possible.

Those who must drive should do so carefully and with dipped headlights, as full-beam lights reflect off the fog, creating a ‘white wall’ effect. When visibility improves, turn off the fog lights.

It  said: “Fog usually occurs in the late autumn and winter months, when conditions tend to be colder, and nights are longer. This type of fog forms as a result of clear skies and light winds. The land cools overnight and this reduces the ability of the air to hold moisture, allowing condensation and fog to occur.

“The fog will often disperse after sunrise, but in some circumstances can last well into the afternoon, and even persist for days on end. This is most likely during January and February, and can cause severe disruption at airports, as well as on roads and for other types of transport.”

When will the fog clear in Birmingham?

The Met Office said in Birmingham, the mist and fog will gradually clear during the day, but will still leave a largely grey and cloudy day through evening, with a maximum temperature of 8C. Tonight (December 1), dense fog remains in places as temperatures drop to 0C.

On Friday (December 2), fog will be slow to clear again as it will stay largely cloudy despite a possibility of a few bright spells and the city will experience a maximum temperature of 7C as the fog is expected to clear at 10am.
