Region: Northern Ireland

An area of rain, falling as snow over some high ground, will move slowly east across much of Northern Ireland during Wednesday, before tending to ease later in the day. This will be accompanied by strong southeasterly winds which may gust 45-55 mph in places, particularly during the morning. Rainfall totals of 10-15 mm fairly widely, with 20-30 mm in some southern and western areas. Whilst many places will see little if any lying snow, there is potential for several cm to accumulate on higher ground, chiefly above 250 metres, with the main focus being over the Sperrins during the morning. 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. If driving, make sure you have some essentials in your car in the event of any delays (e.g., warm clothing, food, water, a blanket, a torch, ice scraper/de icer, a warning triangle, high visibility vest and an in-car phone charger). 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.

Outbreaks of rain, hill snow and strong winds may bring some disruption to travel during Wednesday.
