The UK has entered its third heatwave in as many months, with temperatures expected to climb as high as 35C in some areas later this week, the Met Office has said.

According to the Met Office, on Monday (6 July), the highest temperature was recorded as 34C in Teddington.

Amber heat health alerts have been issued by the UK Health Security Agency (UKHSA) for the Midlands and southern England, from 9am on Wednesday until 9pm on Sunday.

This means significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those aged 65 and over or with health conditions.

The UKHSA said similar significant impacts are possible across these areas, and warned of a potential increase in water-related incidents across England, including risks from cold water shock and drowning.

The Met Office also warned England could experience "tropical nights" later this week, where temperatures will not fall below 20C.

National Rail Enquiries has urged train passengers to check for updates over the coming days because of the heatwave.

Vehicle breakdown rescue companies are also likely to be busier than usual because of the high temperatures.

Drivers are advised to carry plenty of water and conduct essential vehicle checks before setting off, particularly tyre pressures and their levels of coolant and oil.

Tony Rich, a spokesman for the AA on road safety, told The Independent: "With temperatures expected to climb into the low 30s across parts of England over the coming days, drivers should take the heat as seriously as they would ice or heavy rain.

"A few simple checks before setting off can make all the difference. Make sure your tyres are correctly inflated, check your coolant level and carry plenty of drinking water for everyone in the vehicle, including pets.

"If you're planning a longer journey, build in regular breaks and try to avoid the hottest part of the day where possible.

"Should you break down, get yourself and your passengers to a place of safety, ideally behind the safety barrier if there is one, and keep hydrated while waiting for assistance."

The Met Office said UV levels are expected to be high or very high across many parts of the UK throughout the week, and advised people to ensure they use sun protection.

The forecaster further warned pollen levels are also expected to be high or very high in some areas this week.

In Teddington, temperatures are expected to reach highs of 30C today (Tuesday, 7 July), 31C on Wednesday and Thursday and between 27C and 29C for the rest of the week.
