Accumulating snow is most likely over higher ground above 200 metres where 2-5 cm is probable. There is a chance that similar accumulations occur at lower levels in places. Higher parts of Dartmoor could see 5-10 cm.

There is likely to be a risk of ice developing as skies clear into Thursday night.

A deep area of low pressure is expected to bring a spell of prolonged and, at times, heavy rainfall across a large part of the UK this weekend.

Across southwest England, rain is expected to develop during Saturday morning with heavier rain likely later in the day and overnight into early Sunday morning.

50-75 mm of rain is expected to fall fairly widely during this time with a chance that some places over Dartmoor could see 100-125 mm. Strong southerly winds will accompany the heavy rain and may locally exacerbate impacts.

What should I do?

Snowy, wintry weather can cause delays and make driving conditions dangerous. Keep yourself and others safe by planning your route, giving yourself extra time for your journey. Check for road closures or delays to public transport and amend plans if necessary.

If driving, make sure you have some essentials in your car in the event of any delays (e.g., warm clothing, food, water, a blanket, a torch, ice scraper/de icer, a warning triangle, high visibility vest and an in-car phone charger).

Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
