MOTORISTS have been warned over an "increased likelihood" of car crashes as Britain continues to be pelted with icy conditions.
Temperatures plummeted last night and areas continued to be smothered in snow.
A forecaster at The Met Office said: "Outbreaks of rain, sleet, and snow may still cause tricky driving conditions.
"Some roads and railways likely to be affected with longer journey times by road, bus and train services.
"Increased likelihood of traffic collisions due to tricky driving conditions."
It adds: "The area of wet weather currently across this region, with snow falling across higher routes (above 300 m), and potential for heavier bursts to bring temporary lying snow down to around 100 m above sea level.
Yesterday, two "extraordinarily loud" blasts were heard in Edinburgh just after 5am, with numerous residents phoning police to report the sound of a bomb exploding or a building collapsing.
But cops took to Twitter to tell them not to be alarmed and confirmed that the sound was thundersnow - a rare phenomenon when snowfall combines with an electrical storm sparking thunder and lightning.

“With temperatures plummeting fast and snow already falling in some parts of the UK, this month is now odds-on to be the coldest December on record,” said Coral’s John Hill.
“It looks as though this year is our best chance for a long time to have a White Christmas.
“We expect to see the white stuff fall somewhere in the UK on Christmas Day, with Aberdeen and Glasgow the most likely cities,” he said.

HOW COLD DOES IT HAVE TO BE TO SNOW?
Snowfall generally occurs when the temperatures is between 0C and 2C.
It doesn’t have to be below zero to snow as some of the heaviest snowfall seen in Britain is when temperatures are between 0-2C.
Falling snow starts to melt as soon as the temperature rises above freezing but the air around the snowflake is cooled.
If the temperature is warmer than 2C, then the snowflake will melt and fall as sleet rather than snow.
If it’s warmer still, it will fall as rain.

Travelling during snowy and icy conditions is strongly discouraged, but here’s a couple of steps that will help you keep safe if you have to drive in adverse weather.
