Region: Northern Ireland

Rainfall is likely to develop during Saturday, and may become persistent and at times heavy. 20-40 mm of rain may fall widely, with some locations perhaps seeing 60-80 mm, with much of this falling in just a few hours. From late Saturday onwards, increasingly strong, gusty winds and perhaps some thunder will also accompany the rainfall. There is a chance that the heaviest rainfall could remain to the southeast of Northern Ireland, and any rain will clear to the northeast overnight Saturday into Sunday. 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.

There is a small chance that heavy rain may lead to flooding and travel disruption.
