A band of heavy rain, accompanied by a few thunderstorms, is moving slowly northward from the Republic of Ireland. This system is expected to continue northward, bringing periods of heavy rain with a risk of thunder to the south and west of Northern Ireland.
In some areas, 10-15 mm of rain could fall in under an hour, with the potential for 25-35 mm in 2-3 hours in certain locations.
To prepare for potential flash flooding, assess if your area is at risk and consider creating a flood plan and assembling an emergency flood kit. Stay updated on road conditions if driving, or public transport schedules if using buses or trains.
Make sure to have a contingency plan in place for power cuts, such as collecting torches, batteries, a power pack for your mobile phone, and other necessities. If you are outdoors and hear thunder, seek shelter in a safe enclosed space like a car. Avoid seeking shelter under or near trees or other tall structures that could attract lightning strikes.
Weather warnings can change rapidly, so it's important to stay informed by following the latest weather forecast updates from the Met Office.
