Warnings come into force as snowfall is seen across country

Met Office warnings for snow have been raised for the majority of the country, as snow settles in many regions including Essex, Surrey, Leeds, and parts of Scotland.  
Amber warnings for snow have been put in place for Cambridge, Essex, Hertfordshire, Norfolk and Suffolk as a band of heavy snow is forecasted to bring disruption. The Met Office warns of travel disruption, power cuts, and the isolation of rural communities.

The Met Office has also issued a yellow warning for snow and ice until 8pm on Saturday for Scotland, the East Midlands, North East and North West England, and Yorkshire and the Humber.  
This warning comes as snow settles across the majority of the regions, causing traffic disruption and the possibility of power cuts, whilst heavy snow has forced the closure of a Covid-19 testing centre in Kirklees Council, Huddersfield.
The Met Office predicts that new snowfall in this area could range from 1-3 cm is possible at low levels, but reaching 20cm at the highest elevations.  
As snow is settling in many regions in the South East including Surrey, the Met Office has placed an additional weather warning for snow covering parts of the East Midlands, the East of England, and London and the South East.

Currently, the only areas without a warning for snow or ice are the South West of England and Wales.  
Met Office Chief Meteorologist Steven Ramsdale spoke on the wintery flurries:  A milder air mass will move eastwards across the UK early 16 January. But when this warmer, more moist air encounters the cold air situated over eastern parts of the UK snow is likely to fall. 
“Whilst the high ground in the north is likely to see the largest accumulations some snow is likely to fall low levels at times. In fact, parts of east England and East Anglia look most at risk of seeing 1-3 cm with 5-10 cm possible in places.
The milder air will eventually win out with the initial snow gradually turning to rain. This may also bring some flooding issues following recent wet weather and with snow then melting though the snow looks to be the greater hazard.
