Parts of the UK will have another day of sizzling temperatures ahead of three days of yellow weather warnings for thunderstorms.
A yellow weather warning for extreme heat is in place until 11.59pm on Sunday for large parts of the south, east, west, Midlands and north of England, when temperatures are forecast to rise to 32C.
The Met Office has put the warning in place, saying people could experience “adverse health effects”, such as sunburn or heat exhaustion, and transport delays in the hot weather.
In Scotland and Northern Ireland, a yellow warning for thunderstorms is in place from 09.00 Sunday to 23.59 Monday, as the north experiences heavy rain for the next two days.
The forecaster has warned of flooding and power outages as the downpours lashed the two regions.
The warning then spreads to England and Wales on Monday and Tuesday, with only the south-west and south-east of England facing a third day of yellow warnings on Wednesday until 11.59pm, as the rain eases elsewhere.
The warm weather has already led to several bushfires across England, with the latest blaze breaking out in the North York Moors National Park.
North Yorkshire Fire and Rescue Service said it was called to the blaze in Sutton Bank shortly after 6pm on Saturday and firefighters worked through the night to contain the grass to prevent it spreading further.
Met Office forecasters have said there is a significant risk of further bushfires on Sunday as the ground has been extremely dry for an extended period.
An official drought was declared in eight areas of England on Friday by the National Drought Group, which consists of representatives from the government, water companies, the Environment Agency and others.
Three water companies – Welsh Water, Southern Water and South East Water – have introduced hose bans, while Yorkshire Water has announced a ban will start on August 26 and Thames Water is planning one in the coming weeks.
Surrey residents were without water on Saturday after problems hit the Netley Mills water treatment plant.
Thames Water apologized and distributed bottled water to residents in Guilford, Surrey Hills, Dorking and Horsham while engineers worked to restore supplies.
By Sunday morning, the problem had been resolved and residents were told that the water was “gradually returning to the area”.
A statement from Thames Water said: “The issues at Netley Mills water treatment works have been fixed and supplies are gradually returning to the area. We are identifying and unblocking air pockets in the system to allow taps to flow normally. When supplies are restored you may notice splashing , cloudy or low pressure, but this will get better.”
Liz Townsend, from Surrey County Council, criticized Thames Water for supply issues during one of the hottest weekends of the year.
She told BBC Breakfast: “This is happening more and more now with warm weather. We had this problem last year here too. And to be honest, the service is not fit for purpose now and residents are rightly very, very annoyed at what they have to put up with.”
She said Thames Water “failed this time to meet the needs of the vulnerable in and around Cranleigh and Ewhurst”, after she received messages from elderly people saying they had not received any water.
