North Wales Police are warning people ahead of the Easter weekend to ensure they 'take sensible precautions' and not to go on off-road trails 'in search of thrills.'
They say they are concerned that people travelling to the area for the break should be prepared for the weather conditions.
Chief Inspector David Roome from the North Wales Police says “We don’t expect conditions to improve for several days so we want to advise people to plan their route properly, allow plenty of time for journeys and to make sure they are well equipped.”
Most of the main routes are now clear, but minor roads including the Horseshoe Pass and the A543 over the Denbigh Moors remain closed.
