Heavy showers and thunderstorms are likely to break out on Friday afternoon and evening.
Many places will miss the storms, but where they do occur, torrential downpours could bring 30-50mm rain in a hour, with hail and lightning.
The storms will slowly clear northeastwards on Friday night, perhaps not clearing northeast Scotland until Saturday morning.
What to expect
- There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- There is a small chance that some communities become cut off by flooded roads
- There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost
