BRITS were battered by rain overnight after the Met Office issued a yellow weather warning for thunderstorms.
The storms could bring flooding to homes and businesses as well as power cuts, travel disruption and damage to buildings, the forecaster warns.
The Met Office warning had run from 8pm on Sunday to 4am today.
It covers London and South East England, South West England, most of Northern Ireland, large parts of Wales, east of England, Northamptonshire and Warwickshire.
And according to flooding maps for across the UK, there are four areas at risk of floods – from Nottinghamshire to Swindon.
The Met Office said heavy showers and thunderstorms were expected across South West England on Sunday.
A few places may see 20mm to 30mm of rainfall in less than an hour, while other places may not see much rain at all.
Forecasters said frequent lightning, hail and local gusty winds may accompany stronger thunderstorms, particularly across south-western parts of England and Wales.
The Met Office warned: “Some flooding of a few homes and businesses is possible, leading to some damage to buildings or structures.”
Brits have also been warned of possible delays to train services.
They added: “Towards the end of the period, the rainfall is likely to die out, leading to many areas becoming a little drier, although there may still be a chance of showers for many places.”
