Heavy showers and thunderstorms are expected to develop in parts of Northern Ireland, particularly in the east, late in the morning and continuing into the afternoon before diminishing in the evening. Some areas may receive 20 to 30 mm of rain over a span of 2 to 3 hours in places where storms are more frequent. Additional hazards may include frequent lightning, hail, and gusty winds in certain areas.
To prepare for potential flash flooding, assess whether your location is at risk and consider creating a flood plan along with an emergency flood kit. Take steps to secure moveable objects and temporary structures, such as bins, garden furniture, trampolines, tents, gazebos, sheds, and fences, ahead of the arrival of gusty winds. Stay informed about road conditions and public transportation schedules to avoid delays and adjust travel plans accordingly.
In the event of a power cut, having essential items like torches, batteries, a mobile phone power pack, and other necessities on hand can help you cope better. If you are outside during a thunderstorm, seek shelter in a safe enclosed area, such as a car, and avoid being near trees or structures that may attract lightning strikes. Be prepared for weather warnings to change rapidly and stay updated on the weather forecast in your area as recommended by the Met Office.
