The UK is set for another spell of hot weather this week, with temperatures reaching up to 34C in some parts of the country.
A week-long warning over higher temperatures took effect on Saturday in parts of the UK, as the soaring heat poses a greater risk to life for vulnerable people.
A heatwave could be declared on Monday in parts of the south-east, after temperatures reached 29C on Saturday, while up to 31C has been forecast for Monday.
Temperatures will approach the low 30s this week before a peak of 34C on Thursday in the south east, the Met Office said.
But while a prolonged spell of hot weather is expected in parts of the UK, it will not be as hot and humid as last month's heatwave.
And a yellow rain warning came into force in parts of north-west Scotland at 5pm on Sunday, until 10am on Monday, where there could be 40mm of rainfall widely and up to 100mm over the highest ground, the Met Office said.
Yellow heat health alerts have been issued by the UK Health Security Agency (UKHSA), covering the East Midlands, east, south-east and south-west of England, including London, and the West Midlands, from midday on Saturday until 8pm on 11 July.
Met Office meteorologist Becky Mitchell said on Sunday: "This coming night should be quite warm across much of England, temperatures in the mid to high teens.
"At 1am in the South East of England temperatures will still be around 16 or 17C, further north, you're looking at 14 or 15C, so pretty warm for overnight."

Ms Mitchell added that temperatures reached 29C on Saturday.
She said: "We're already in heatwave threshold category in the South East so, by the end of tomorrow (Monday), the South East will officially be in a heatwave."
Last week the UK set a provisional June temperature record of 37.7C in Lingwood in Norfolk, according to the Met Office.
It beat the previous June record for the UK of 35.6C, which dates back to 1976.
