The warning is covering parts of East Midlands, East of England, London and South East England, North West England, South West England, Wales, West Midlands. All local areas affected are listed below.
A Yellow weather alert is in place during Monday, starting from around 1pm and running until 11pm. Forecasters say the affected regions can expect to see frequent lightning strikes and heavy rain.
The Yellow warning for thunderstorms was announced at 10:59am on Sunday, May 11.
A Met Office forecast said: “Scattered showers and thunderstorms are expected to develop on Monday afternoon. Whilst these will be fairly fast-moving, rain may be intense for short periods of time and produce 20-30 mm in less than an hour, with 40-50mm within 1-2 hours in one or two places where thunderstorms grow larger. Lightning, hail and gusty winds will be additional hazards. Showers and thunderstorms will ease through the evening.”
What to expect
Spray and sudden flooding could lead to difficult driving conditions and some road closures; 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; There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost; Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.
What should you do during intense thunderstorms?
Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit. Prepare to protect your property and people from injury. Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured. Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.

What is a yellow weather warning?
The Met Office has three categories of weather warning, depending on the likely impact of severe weather and also how likely it is to strike in a particular area.
A yellow warning is issued when weather conditions are expected to disrupt travel and traffic and may impact on daily routines but are not likely to pose a risk to life or property.
An amber warning is more severe and advises people to think about changing their plans to minimise the risk.
A red warning means weather conditions are expected to be dangerous with widespread damage to property and a risk to life, with the public usually advised to avoid travelling.
The Yellow weather alert for thunderstorms will remain in place until 11pm on Monday.
