In London, the weather is expected to remain unsettled this week, with isolated showers developing into heavy downpours, bringing a risk of thunder.

Frequent heavy showers are expected on Friday morning, gradually giving way to a mixture of sunshine and isolated showers by the afternoon.
Met Office Chief Meteorologist Steve Willington said: “A westerly regime is now in charge of the UK’s weather and will help fuel periods of wet and windy weather over the next few days, with showers and some longer spells of rain likely for much of the UK on Thursday and Friday.
“While many areas may welcome some rain after fairly prolonged dry weather, there’s a potential that over the next few days some parts of Wales, northwest England and western Scotland could see some impacts at times, which we’ll be keeping an eye on.”
Around 10-20mm of rainfall is expected, with some areas nearer the coast seeing up to 50-70mm over a few hours.
It follows a scorching Bank Holiday weekend, as temperatures reached upwards of 28C in the capital on Monday for Notting Hill Carnival.
Strong winds and heavy rain is forecast on Saturday as an area of low pressure moves in from the southwest.
David Oliver, Deputy Chief Meteorologist at the Met Office, said: “A deep area of low pressure will develop close to the UK on Saturday and track northeast over the weekend, bringing wet and windy weather for many.
“While the exact track and depth of the system is still a little uncertain, at present it looks likely that we’ll see gusts in excess of 50mph in some areas during Saturday and Sunday, especially across coasts, headlands and high ground.
“In addition to these gusty winds, 10-20mm of rain is likely across many regions, with higher totals over hills in western areas.”
