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.

Scattered heavy showers and a few thunderstorms are expected during Sunday. Rainfall amounts will vary from place to place but in some locations 20-40 mm is possible within a couple of hours. Heavy downpours of rain will be the primary hazard, but lightning strikes and hail are also possible. What Should I Do? 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. If you find yourself outside during a lightning event, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. 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.
