Forecasters have said “wintry hazards” are set to come to the capital after a fortnight of weather which has been “exceptionally mild” in places compared to January averages.
Ice and frost are expected to hit the capital from Monday into Tuesday while temperatures are expected to plummet throughout the week.
The Met Office has said there is a chance of snow in parts of the South East – but not London – into Tuesday morning with the temperatures not predicted to be above 5C all of next week until January 20. However, strong winds, icy rain and sleet could make it feel like it is a sub-zero day for anyone out in the capital.
“It will turn colder with a northerly airflow bringing wintery hazards,” said Met Office spokesman Grahame Madge.
“It is nothing extreme for January…This is more of a reminder that it is winter but it is not a Beast from the East scenario,” he said about the 2018 storm which wreaked havoc in the UK.
“January has been mild and exceptionally mild for some areas.”
Mr Madge said the “strong northerly airflow” in the middle of next week will “make it feel cooler than it already is”.
The Met Office has not given a weather warning for London at any time this week but there are yellow ‘be alert’ cautions listed for other parts of the UK.
For Sunday, Scotland is set for snow and ice while much of the north will see ice. On Monday, these warnings will remain in place while there is also a chance of snow in the south and south west, but not in London – which is consistently warmer and flatter than surrounding southern areas. On Tuesday and Wednesday, only Scotland has a warning for snow and ice in place.
Residents are urged to take care as there may be some icy patches on some untreated roads, pavements and cycle paths and some roads and railways are likely to be affected with longer journey times by road, bus and train services.
Earlier, flood defences, including boarding, were deployed in York city centre.
City of York Council said it had taken the measure to keep the area “safe and open” as it urged visitors to plan their journeys in advance.
Rescue workers were seen using a boat to navigate the floodwater in the centre of York after the River Ouse burst its banks.
