The Met Office is warning that heavy rain could bring a build-up of up to 80 to 100mm of water as it issues a thunderstorm warning.
The yellow warning – the least severe of three possible warnings issued by the forecaster – will come into force at 10am on Friday and will remain in place until midnight.
What to expect:
- There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater.
- Spray and sudden flooding could lead to difficult driving conditions and some road closures.
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.
Heavy showers are expected across much of the UK and the showers and thunderstorms will be slow-moving and may cause localised surface water impacts.
Rainfall totals will vary considerably and not all locations will be affected by the heaviest showers.
Where there are showers there is potential for 20-30mm of rain in a short space of time and during the course of the day, there is a chance that some places could see as much as 80-100mm build up.
