West Somerset is shivering in the big freeze on Wednesday with the temperature forecast to stay below zero all day.
Clear skies overnight and into Thursday will see the temperature drop as low as minus 6C in Wellington, with a predicted minus 3C on Exmoor and in Wiveliscombe.
Minehead, benefiting from its coastal position, will fare slightly better, staying above freezing during the day but reaching freezing point overnight.
A Met Office Yellow warning for ice was scaled back to cover Devon and was due to end at 10am on Wednesday, as the worst of the wintry weather hit Scotland and the North East of England.
Somerset has seen snow flurries during the week after wintry showers arrived at the weekend, blocking some roads on high ground on Exmoor.
The Met Office is forecasting a dry Thursday for the region, with plenty of sunny spells after frost and fog clears.
Friday and Saturday are expected to stay dry, but will turn cloudier with showers arriving on Saturday, with snow turning to rain as the weather turns milder.
Somerset County Council’s public health team is encouraging people to check on those most at risk from the effects of the cold weather.
People are being advised to try to maintain indoor temperatures to at least 18C, particularly if you are not mobile, have long term illness or are 65 or over. If you can’t heat all the rooms you use, heat the living room during the day and your bedroom just before you go to sleep.
Wear a few layers of thin clothing rather than one thick layer; this will trap the heat better to keep you warm. Thin layers of clothes made from cotton, wool or fleecy fibres are particularly good for maintaining body heat.
