Expect heavy rain moving northwest across Scotland from Wednesday afternoon, with the most persistent rain over northern and eastern hills. Rain will become more showery in central and southern areas on Thursday. There is uncertainty regarding the duration and location of the heaviest rainfall, with a small chance of it becoming slow-moving over Moray and northern Aberdeenshire, possibly affecting Lothian and Borders to a lesser extent. In the event of this scenario, some areas could receive 60-80 mm of rain in 12 hours, with a very low chance of 100 mm.
To prepare for potential flooding, check if your property is at risk and consider creating a flood plan and emergency kit. Ensure you are aware of road conditions if driving, or bus and train timetables, and adjust your travel plans accordingly. Have essential items ready for power cuts, such as torches, batteries, a mobile phone power pack, and other necessities. Stay updated on weather warnings as they may change quickly, and keep informed by monitoring the forecast in your area.
