The 49-year-old prefers to stay outside all the time than go in and out of shelters.

"So if I stay outdoors it's better."

The assistant manager of a pub in Cornwall has told of how it looked after an extra 150 people who had to stay overnight because of the weather.

Katie Smith, from the Jamaica Inn, told BBC Radio 5 Live: "A lot of people came quite far to just get into the warm."

The pub, which is just off the A30 in Bodmin Moor, welcomed many people who had abandoned their cars after the road ground to a halt - with some walking for miles to reach the Jamaica Inn.

As a result, staff had to set up extra beds throughout the restaurant, used bedding from their storeroom and lit fire places.

Ms Smith added that the staff worked incredibly hard to cater to as many people as possible, with one cook being at the premises for 16 hours.

Woburn Safari Park in Bedfordshire is closed today, while Bristol Zoo says it is opening late - at 10:00 GMT - to give staff time to clear snow.

Matt Argyle, from North Devon, was stranded in his car for nearly 12 hours on Thursday because of the weather - and finally got home in the early hours of Friday morning.

He had been travelling back to Devon from St Austell in Cornwall on Thursday afternoon when the snow started coming down heavily in Bodmin.

He said: "It just absolutely dumped, within about half an hour we were completely stuck, traffic queues for miles. Very pretty, but not very convenient.

"I was there from about three o'clock until about 11.30 at night, then a snow plough came through which we followed.

"Bit of an epic journey. Got back about 2.30 this morning."

He added: "I must have had a premonition yesterday because before I left home I put a sleeping bag, a shovel, a load of food and some water in my car."

"I didn't really think I'd need it but it was brilliant, I was wrapped up in my sleeping bag on Bodmin Moor in a big traffic queue."

If you're thinking of driving today, RAC urges you take "extreme care".

Kevin Andrews, from the company, says "drive with caution, take everything nice and gentle on the throttle, the brakes, the steering".

"The road is very, very treacherous indeed," he adds.

"My advice personally would be to stay at home, it's just not worth it."

He adds: "But if you have to go out, take two extra coats - one to wear and one to sit on if need be."

And take a good quality screen wash - "water just freezes, no good at all" - and make sure there's no snow on the car, especially on the windscreen or the wiper area.

"If you get stuck, there's not a lot anyone can do but be prepared," he said.

"Make sure your phone is charged up, extra warm clothes, put extra food in the car. Just think - what would you need?"

What would a day like today be without the odd snowball fight?

A company in Gloucester shared this clip of a snowball duel outside work on Friday morning.

Meanwhile, one father tweeted to his boss to say he was planning to go sledging with his children before coming into the office.

And in the south west of England, staff at one grain storage company shared this photo.

Are you needing to clear a pathway of snow this morning to get out and about?

The Home Office, external gives this handy advice:

• do it early in the day - it’s easier to move fresh, loose snow
• don’t use water - it might refreeze and turn to black ice
• use salt if possible - it will melt the ice or snow and stop it from refreezing overnight (but don’t use the salt from salting bins as this is used to keep roads clear)
• you can use ash and sand if you don’t have enough salt - it will provide grip underfoot
• pay extra attention when clearing steps and steep pathways - using more salt may help
