Persistent and at times heavy rain may lead to some travel disruption and brief flooding of a few places. What to expect: Spray and flooding on roads probably making journey times longer Bus and train services probably affected with journey times taking longer Some interruption to power supplies and other services likely Temporary flooding of a few homes and businesses is possible Further details: A spell of persistent rain is expected to arrive across Northern Ireland early on Tuesday morning, with some heavy bursts developing at times especially during Tuesday afternoon and evening, before the rain clears late on. Widely 20-30 mm is probable over the course of around 18 hours, with some high ground perhaps receiving 40mm or more, eg Mourne Mountains. However, within the broad area of rain there are likely to be periods with heavier bursts containing 10-20 mm over a 1-3 hour period which could cause a few issues such as temporary surface water flooding and difficult travelling conditions. In addition stronger winds are likely to develop along some eastern coasts, adding to the potential for disruption in a few places. 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.
