Region: Wales

An area of heavy rain is expected to move over central and 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.
