The Level 3 Heatwave Action Amber warning has been extended for a further two days throughout most of the country, with temperatures forecast to edge close to 35C over this weekend in some regions. The Met Office said there is now a “90 percent probability of Heat-Health Alert criteria being met” between 9am today (Friday) and 9am on Tuesday in parts of England. The Amber alert applies to London, Southeast England, East of England, Southwest England, East Midlands, West Midlands, North West England, Yorkshire and the Humber, and North East England.
An “Amber Heatwave Action” is “triggered when the Met Office confirms threshold temperatures for one of more regions have been reached for one day and the following night, and the forecast for the next day has a greater than 90 percent confidence level that the day threshold temperature will be met.
“This stage requires social and healthcare services to target specific actions at high-risk groups”.
The Met Office said that thanks to the influence of high pressure positioned over the UK, the heat will continue to build through the rest of week, peaking on Friday and Saturday.
Heatwave criteria is now being met, with temperatures peaking at 35C today and possibly at 36C on Saturday and Sunday.
Met Office Chief Meteorologist Frank Saunders said: “Persistent high pressure over the UK means temperatures have been rising day-on-day through this week and it is important people plan for the heat.
“Temperatures are expected to peak at 35C on Friday and possibly 36C on Saturday and Sunday.
“Even beyond this, hot conditions will persist in parts of the south of the UK as far as late Monday, and it will turn increasingly humid.
“We will also see some warm nights, with temperatures in some places staying in the low 20s Celsius.”

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency (UKHSA), said: “Temperatures will feel very warm again this week, particularly in southern and central parts of the country.
“We want everyone to enjoy the warm weather safely when it arrives, but remember that heat can have a fast impact on health.
“It’s important to ensure that people who are more vulnerable – elderly people who live alone and people with underlying health conditions – are prepared for coping during the hot weather.
“The most important advice is to ensure they stay hydrated, keep cool and take steps to prevent their homes from overheating.”
Today, the UK officially declared a drought for parts of England, with millions of Britons hit with hosepipe bans as a result of the sustained period of hot weather.
The drought is the first in the country since 2018 and will likely force more countries into imposing hosepipe bans on millions of other people.
This follows England’s driest July in nearly 90 years which saw temperatures surge to a record 40C for the first time.
Following a meeting of the National Drought Group, Water Minister Steve Double said: “All water companies have reassured us that essential supplies are still safe, and we have made it clear it is their duty to maintain those supplies.
“We are better prepared than ever before for periods of dry weather, but we will continue to closely monitor the situation, and take further action as needed.”
Earlier this morning, the Met Office also issued yellow thunderstorm warnings for much of the UK, beginning in Scotland and Northern Ireland from Sunday afternoon.
As the scorching weather subsides in the north, this could trigger “intense” thundery downpours and the threat of some surface water flooding.
The warnings come into effect from 12pm on Sunday in Scotland and Northern Ireland, with subsequent warnings issued further south, including much of England and Wales, from early on Monday.
