About 130 schools have shut and several roads are closed after snow fell across parts of Wales.
There are three yellow warnings in place for snow and ice across the UK, including Wales.
Snow left one road impassable and collisions on two others roads, with schools across mid and north-east Wales shut on Tuesday morning.
Snow started falling across parts of the UK on Monday night in what the Met Office called the country’s “first taste of winter”.
Schools have already closed for the day in Wrexham, Powys, Denbighshire and Flintshire.
On the roads the A44 in Powys was impassable and was shut in both directions from the A470 at Llangurig to the B4343 at Dryffryn Catell.
Traffic Wales also reported crashes on snowy roads causing a closure on the A55 eastbound at Caerwys in Flintshire.
The A483 southbound between Rossett and Gresford in Wrexham county was also shut after a collision in the snow.

BBC Wales Weather presenter Sue Charles said about 2-5cm of snow had fallen across parts of north, east and mid Wales, with up to 10-15cm on the hills.
She added: “Snow is becoming less of a risk later with a band of rain, sleet and snow moving south-eastwards – but it’s a weakening feature – with snow becoming more confined to higher ground and the hills.
“Widespread frost inland overnight with frost and ice risk early tomorrow [Wednesday] then a day of sunshine and wintry showers.”
