Weather warning issued for freezing fog

A series of weather warnings have been issued due to freezing fog, which can cause air pollution and harsh driving conditions.

The Met Office said the fog would be so dense that visibility in parts of the UK could drop to as low as 50 metres.

The yellow weather warning is in effect between midnight and 11:00 am on Sunday and the heaviest fog is expected from Yorkshire to East Anglia.

A “moderate” air pollution warning was also issued by the mayor of London, Sadiq Khan, where foggy conditions cause poor distribution of vehicle emissions.

“On Sunday, besides the extreme cold we are experiencing, we expect moderate to high levels of air pollution.

“We must all be careful in the coming days.

“I urge Londoners to look after each other by choosing to walk, cycle or use public transport, avoid unnecessary car journeys, stop the engine idling and not burn wood or garden waste, all of which contribute to high levels of pollution.

“This is particularly important to protect those who are more vulnerable to high pollution.”

But Met Office meteorologist Craig Snell said the worst of cold weather is over and temperatures are expected to rise across the whole of England next week.

Mr Snell said: “Next week, looking at the violent front, it looks pretty benign.

“We are starting to lose the risk of fog and temperatures are often where they should be.

“We will probably lose the really hard frosts. In terms of ice and snow, it looks like we’ve definitely gotten through the worst.

“Overall we have to be mindful of the risk of fog during this cold period, but the main dangers from it seem to be starting to wane.”

Nighttime temperatures across the country are predicted to still be below zero over the weekend and will climb to around 5C in the Southeast and 10C in the North.

Mr Snell explained that temperatures will be lower in the South, which is often warmer than in other parts of the country, due to a change in wind direction in the North West.

The shift will see an Arctic boom that has swept the UK over the past five days and is replaced by warmer air from the Atlantic, but it will take longer to reach the southern regions.

After freezing conditions on Saturday, many sporting events were canceled and travel was cancelled.

The Sky Bet Championship match between Blackpool and Huddersfield was postponed due to frozen pitch and a race meeting at Haydock was canceled due to icing.

The CalMac ferry, which serves the islands off the west coast from mainland Scotland, also canceled flights due to weather.

National Rail said trains between Three Bridges in Wessex and Brighton, Hove and Sussex were disrupted due to points error, but did not specify whether this was due to icing.

It came after temperatures dropped below minus 10C in parts of England this week due to snow and ice.

Drumnadrochit, near Inverness in the Highlands, hit minus 10.4C early Thursday, making it the coldest temperature ever recorded of the year.
