Brits will be drenched in severe downpours today, with millions likely affected by the rainstorms.
The Met Office has issued yellow weather warnings that cover large parts of England. This includes an extensive section from the north to the south.
The only areas that will not be affected are the southwest, Wales and the extreme west and east of England.
Heavy showers will hit Brits from midday until midnight. This alert could lead to flooding.
The forecast for heavy rains in the next few hours means that roads and public transport may be affected.
The weather agency also warns there is a slight chance of power cuts and damages to homes and businesses affected by flooding.

Where will the rain arrive?
Newcastle and Sunderland, fully covered in the yellow warning, will start the day with overcast skies. Rain will start as early as 9am, with heavy rains from 10 am to 1pm.
Although the sun will try to break the cover, there is still a 30% chance for rain to fall. This can increase to 40% in the evening. Around 6pm, the rain is expected to stop.
Areas such as York, Leeds, Sheffield, and Lincoln will wake up to clouds that will remain for most of the morning. From around 11am to after noon, heavy rain is expected for the next two hours.
Light showers with occasional sunshine will be possible, but there are less downpours in the north. At 6pm, dry skies and more clouds are expected.
The very western parts are likely to escape the storms but Greater Manchester, the Peak District, and areas further away from the coast are at risk of rainfall today.
Greater Manchester will experience a poor start to the day, with heavy rains in the morning and heavy downpours at 7:08am. A break will be in place for lunchtime, with dry conditions between 10am to 3pm. Then light showers will return.
Those living in Birmingham, Nottingham, Northampton, Leicester, and Peterborough will follow a similar pattern as the northwest. Showers will begin earlier with 50% chance of rain between 6am and 9am.
The sun will shine through the clouds between lunchtime and afternoon, which is a good thing as it gives us a break from the cloudy skies. It will be a dry day, with no rain forecast for the later part of the day.
London on the other hand will have a wet and dreary Sunday to end the weekend, with the first spots of rain appearing at 10am and returning at lunchtime. There is a 50% chance that rain will fall for several hours in the afternoon.
The weather alert will end at midnight. It is expected that Greater London will experience some rain through the day, and then there will be light showers later in the evening.

Only the furthest parts of the east of England are set to escape the downpours, such as Norwich.
The rain will begin at 3pm in Essex and lasts for several hours, most likely until 9 pm.
There may be some sun in other parts of the east, but it will be raining all day.
