The Met Office has upgraded the weather warning for Bath as intense, heavy snow and potentially dangerous ice are expected to cause havoc.
The severe weather warning has been upgraded from yellow to amber for snow and ice.
It's set to be in place from 2pm on Thursday (March 1) until 8am on Friday (March 2) - with forecasters predicting snow to fall continuously from Thursday morning until Friday night.
Temperatures will also plummet to around -5C and stay below freezing point until rising to 1C, but the bitter cold could 'feel like' -12C.
The chief forecaster for the Met Office said: "A weather system is expected to move slowly north through Thursday, intensifying and pushing north across the warning area from Thursday afternoon.
"As it comes into contact with the very cold air resident over the UK, it has potential to produce widespread snow, accompanied by strong to gale force winds.
"As less cold air follows from the south, there is a chance of snow turning to freezing rain bringing an additional significant ice risk.
Some forecasters are predicting these will be the most extreme weather conditions in years as the Beast from the East tightens its grip on Britain.
During the weekend, snow across the UK should slowly clear from the south.
Dr Thomas Waite, of public health England's extreme events team, said: "When the wind drives temperatures even lower, the risks to health can increase as even people not normally at risk from cold-related illness can feel the effects more.
"This is why it's so critical to keep warm; a good way is to keep homes heated to at least 18C.
"In weather like this our bodies have to work harder, older people, young children and those with long term conditions like heart and lung diseases, can really struggle to cope in such low temperatures.
Highways England's Head of Road Safety, Richard Leonard, added: "Gritters are out treating our routes around the clock but it is still important to drive to the conditions when snow is forecast.
