Region: Wales

Wintry showers will feed southwards across southwest Wales and parts of Devon and Cornwall through Wednesday and Thursday, moving well inland on brisk northerly winds. Some snow accumulations will be possible in places, especially overnight and/or farther inland away from the immediate windward coast. Whilst some places will see little or no lying snow, where showers are most frequent accumulations of 2-5 cm are possible, and perhaps up to 10 cm in a few isolated spots, more especially on hills above 200 m elevation in Pembrokeshire and west Carmarthenshire. Gusty winds and hail may accompany some of the showers, and where showers persist and/or snow partially thaws and refreezes overnight, this will bring a risk of ice. What Should I Do? Snowy, wintry weather can cause delays and make driving conditions dangerous, so to keep yourself and others safe: plan your route, checking for delays and road closures, amending your travel plans if necessary; if driving, leave more time to prepare and check your car before setting off; make sure you have essentials packed in your car in the event of any delays (warm clothing, food, water, a blanket, a torch, ice scraper/de-icer, a warning triangle, high visibility vest and an in-car phone charger). Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal to reduce your risk of accidents, slips, and falls. If making a journey on foot, try to use pavements along main roads which are likely to be less slippery. Similarly, if cycling, try and stick to main roads which are more likely to have been treated. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
