Region: Northern Ireland

A spell of very heavy rain is expected to affect parts of east and southeast Northern Ireland during Sunday night and at first on Monday morning. There remains some uncertainty in the northern extent of the heaviest rain, but some places are likely to have 50-75 mm of rain in a short space of time with a risk of flash flooding. 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, consult NI:DIRECT. Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities.

Region: Northern Ireland

A band of rain will become heavy and persistent during Sunday night and Monday, most likely across more eastern and southeastern parts of Northern Ireland. There remains a good deal of uncertainty as to the east-west position of this rain band, but where it does occur some places could see 50-75 mm in 12-18 hours. 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 may cause some flooding and disruption during Sunday night and Monday.
