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

What should I expect?

  • Delays or cancellations to train and bus services are possible
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • Possible power cuts and loss of other services to some homes and businesses
  • Some communities may be cut off by flooded roads
  • Fast flowing or deep floodwater is possible, which could cause a danger to life

What should I do?

Further detail

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 may cause travel disruption and flooding this weekend

What should I expect?

  • A few homes and businesses flooded
  • Bus and train services affected with journey times taking longer
  • Spray and flooding on roads will make journey times longer
  • Some interruption to power supplies and other services

What should I do?

Further detail

Further spells of rain, heavy at times, are likely during Saturday afternoon and night before clearing into the North Sea by dawn Sunday. 20-30 mm may fall fairly widely with a chance of 50 to 60 mm over high ground in a few places. Strong winds may accompany this heavy rain, particularly during the evening.

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.

Icy stretches could cause some disruption on Saturday night and Sunday morning.

What should I expect?

  • Some injuries from slips and falls on icy surfaces
  • Probably some icy patches on some untreated roads, pavements and cycle paths

What should I do?

Further detail

Following rainfall earlier in the evening, surface temperatures are expected to fall widely below freezing. With surfaces left wet, ice is expected to form on untreated surfaces and may lead to hazardous travelling conditions.

What Should I Do?

Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal. Not needing to rush, reduces your risk of accidents, slips, and falls.

If you need to make 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.
