London is enjoying “summer’s last hurrah” before heavy rainfall is expected to drench the country over the weekend, the Met Office has said.

Warm and bright conditions are expected to continue into today after a cloudy morning – with highs of 25C in London, the weather service added.

Met Office meteorologist Dan Stroud said: “We are being spoiled by almost summer’s last hurrah, but there’s a bit of a change coming down the line as we move our way through towards Friday, and especially the weekend.”

“Successive bands of rain” and “normal conditions for autumn” are expected next week, he added.
