The island was hit by widespread snowfall on Thursday night
Schools on the Isle of Man remain closed for a second day due to heavy snowfall overnight.
All schools and colleges on the island were closed on Thursday due to the deteriorating conditions.
Ronaldsway Met Office said while the snow would "soon turn slushy" in the morning's bright and sunny conditions, a widespread frost would create "hazardous conditions on the pavements and roads" later.
A government spokeswoman said "the safety of pupils and staff travelling to and from school across the island is of paramount importance".
Nick Weston in Ainley Top, West Yorkshire, is one of those people mentioned in Mairead's post below who've been busy clearing their driveways.
"It happens every year," he says. No doubt he's earned a hot cup of tea after all that effort.
As you'll see in the second pic, the snow has given locals some beautiful views of the countryside, even if the driving conditions have been very arduous.

Reporting from the M62
After a tough night and early morning for motorists on this section of the M62 in West Yorkshire, traffic is beginning to move more freely on the westbound side but problems still persist eastbound which is largely free of any vehicles.
Dog walkers have still braved the nearby pavements, and people living here have spent time clearing thick snow from their driveways.
Flights are also delayed at Leeds Bradford Airport this morning, with three departures cancelled so far.
"At present, LBA is open. However, adverse weather conditions have caused disruption to flight schedules. Please check our website and your airline's website for updates," the airport tweeted., external

Like his PA Media colleague from whom we heard a little earlier, McCarthy had been in Manchester to cover last night's Manchester United match.
"The worst bits are around Huddersfield," he said. "A couple of highway patrolmen gave me a push when I was stuck, but said they couldn't promise that the road ahead would be more clear. Thankfully, it was."
All types of vehicles were getting stuck in the challenging conditions, he added.
"I saw lots of abandoned sports cars: one Jaguar left on the road with a shovel stuck in the ground next to it and no driver.
"There were lots of lorries losing momentum and getting stuck [too]."

Any good news?: Yes! The worst of the weather is expected to abate mid-morning, according to BBC weather forecaster Simon King.
As we've been reporting, heavy snow overnight left the M62 motorway at a virtual standstill - and there are still severe delays on parts of the route this morning.
The worst disruption is between junction 20 (Rochdale) and junction 24 (Huddersfield) in both directions, with lane closures and three-hour delays.
There is currently 17 miles (27km) of congestion between these junctions, according to the latest update from National Highways., external

PA journalist Simon Peach earlier said he'd been stuck on the M62 for more than seven hours, and was at a standstill "for a really long time" as temperatures plummeted to -4C.
"I've moved about 25 miles over the course of the night," said PA's chief football writer, who was covering Manchester United's Europa League match at Old Trafford last night.
"A road sweeper came along once or twice, but they haven't been able to clear the roads properly."
He added: "I've never had to drive through anything like this before. My drive home would usually be about an hour and a half, the most it has ever taken me is two and a half hours.
"I could have flown to New York!"
Our correspondent Mairead Smyth earlier gave this update from a bridge over the snow-hit M62.
She spoke to people who got stranded overnight after attending events in Manchester.
Mairead said: "That amber weather warning is in place in this part of the country until midday."

Kim Ward was on her way home to Halifax from Manchester overnight, with various members of the family, when their car got stranded.
"We are still stranded at the moment," Kim told BBC's Radio 5 Live's Rachel Burden early this morning.
Kim, who went to a concert in Manchester with her sister-in-law, a niece and a friend, said they had considered not travelling last night, but had assumed their car - a 4x4 - would cope in the conditions.
But the return journey turned out to be considerably worse than expected.
"The M62 was shut, so we thought we would take the A road," she said.
"We thought we would be alright, but as we got higher and higher, it just got worse and worse.
"We spent a couple of hours completely stuck, freezing - we actually started nodding off in the car.
Quote MessageNext thing we knew mountain rescue were knocking on the window with their torches. They brought us here this morning."
She went on to say: "I have been on numerous ski holidays, but I have never seen anything like it, up on the top there.
"It's scary, thinking you are going to actually spend the night here in the car."
