Showers, potentially thundery, are expected in parts of western Scotland on Sunday afternoon. More heavy rain, with possible thunder in the south, will move from the south on Sunday evening. There may be intense downpours in some areas, leading to 20-30 mm of rain in less than an hour and possibly 30-50 mm over 2-3 hours, causing surface water flooding.
To prepare for possible flash flooding, it is recommended to create a flood plan and have an emergency flood kit ready. Check road conditions and transportation schedules to avoid delays. Be ready for power outages by having essential items like torches, batteries, and a mobile phone power pack on hand.
If caught outside during thunder, seek shelter in a safe enclosed space like a car, avoiding trees and tall structures. Stay informed as weather warnings may change rapidly. Keep updated with the local weather forecast when warnings are issued.
