Met Office, UK weather and danger to life

A white Christmas is when a single snowflake is observed falling during the 24 hours of 25 December by either an official Met Office observer or one of the Met Office's 300 or so automated weather stations. So just a snowflake - rather than a blanket of snow covering a street - is needed for it to be defined as a white Christmas.
The Met Office will likely extend its long-range forecast up to December 25 in the next few days, but given its prediction so far, a white Christmas seems unlikely.
Weather forecasters have predicted snowfall across vast swathes of the country this month with as much as five inches of snowfall expected in some areas across the UK
