Region: Wales

An area of heavy rain is expected to move over south Wales between late Sunday and late Monday. Whilst rainfall amounts will vary, some heavy and persistent rainfall is likely to fall, especially over high ground, for example Bannau Brycheiniog. Rain should clear to the east Monday night. 20-40 mm of rain is likely to fall quite widely across the wider region, but 60-80 mm is likely to accumulate over some windward-facing high ground in south Wales and perhaps nearer 100-120 mm in a few places. Strong south to southwesterly winds will accompany the heavy rain, particularly in coastal areas. What Should I Do? Keep yourself and others safe; prepare to avoid travelling by road during potentially dangerous road conditions. If you must travel, ensure you watch for possible danger and drive cautiously. It is not safe to drive, walk or swim through floodwater, avoid it where possible and if you are affected by fast flowing or deep-water call 999, and wait for help. Preparing a flood kit could save you from loss or damage due to flooding to your home or business. In your flood kit have: insurance and any other important documents; a torch & spare batteries; a first aid kit, prescription medicines and supplies for looking after your family members or pets; and, warm, waterproof clothes, blankets, food and water. Consider checking on vulnerable people that you know including older people, those with underlying conditions and those who live alone; they may need support with food and medical supplies. If you are worried about your health or that of somebody you know, ring NHS 111. Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities.

Heavy rain is likely to bring some disruption and probable flooding on Monday.

Region: Wales

An area of heavy rain will move in from the west late on Sunday evening, becoming widespread across the region early Monday, before clearing to the east Monday night. Rainfall accumulations will vary across the region, but 20-30 mm of rain may accumulate quite widely. As much as 60-80 mm of rain could build up across the high ground of Dartmoor, and perhaps 40-50 mm of rain could accumulate across the higher parts of Exmoor, Dorset, the Mendips and Cotswolds. Strong south to southwesterly winds will accompany the rainfall, particularly near English Channel coasts. What Should I Do? Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit. 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 quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.

Heavy rain could bring some disruption during Monday.
