The Met Office has extended its snow and ice weather warning covering Hertfordshire.

The forecaster has urged motorists to plan ahead for the yellow warning, which came into force on Monday evening and will now cover the region until 9am tomorrow (Thursday).

There has been a smattering of wet snow and sleet overnight in Hertfordshire and London, which will push further north as the day goes on, but travel has not been too severely affected.

It comes as temperatures plummet nationwide following warnings of a possible ‘Beast from the East 2’ in recent weeks.

Disruption is not expected to be anywhere near as severe as in 2018, but motorists have been warned of "ice and some snow leading to difficult travel conditions in places".

Some roads and railways will "likely" be affected, with longer journey times expected, and "probably" some icy patches on untreated roads, pavements and cycle paths.

The winter sting in the tail is scheduled to last for most of the week.

Met Office Deputy Chief Meteorologist Steven Keates said: “The impactful weather will continue through the second half of the week as mild air meets cold air with further snow, ice, wind and then rain likely later in the week and into the weekend.

“From Wednesday, the focus of further snow is across parts of southern England and south Wales, with snow likely to lower levels for a time, and many may wake up to a couple of centimetres of snow on Wednesday morning.

“Through Thursday and Friday the snow risk spreads to central and northern areas of the UK, though it’s not possible to pick out precise locations regarding who will see the heaviest snowfall. With a developing situation, it’s important to stay up to date with the latest forecast and further warnings are very likely.”
