Bank holiday weather: 'thundery downpours' loom for southern England Notting Hill carnival: bank holiday rain threatens to dampen spirits
(about 4 hours later)
Wet and windy weather will blight parts of the UK on Sunday, continuing a disappointing Bank Holiday weekend. Revellers at the Notting Hill carnival will be packing umbrellas along with their whistles and horns, with heavy rain expected to soak London and much of the south of England later on Sunday and throughout Monday.

The Met Office has issued a yellow weather warning in London, the east, south-east, and south-west of England, alerting the public to “thundery downpours” ahead. Those partying at Manchester Pride and the Creamfields festival in Warrington should have more luck on Sunday afternoon, with north-west England expected to remain dry, despite some cloud coming in from the south as the day wears on.
Up to 25mm, or half a month of average rain, could fall in some areas, becoming increasingly heavy throughout the day before spreading to the North overnight. Temperatures are expected to reach about 20C in the south-east and no more than 17C or 18C in the north-west, as summer slowly slips away into autumn.
The Met Office said: “Although not all areas will be affected, thundery showers or areas of heavy rain are likely to affect some southern and eastern parts of England late on Saturday evening and on Sunday. Conditions are forecast to worsen across the country as the night wears on and into bank holiday Monday, with heavier rain expected in the south of England all day and spreading north.

The Met Office has issued a yellow weather warning for Sunday in London, the east, south-east and south-west of England, with 25mm of rain expected in some areas.
“Very awkward for Notting Hill. I think I’d veer more towards umbrellas than suncream,” the Met Office forecaster Steven Keates said.
“For the first half of the day there could be the odd bright spell, but I think on the whole a fair amount of cloud. From mid-afternoon onwards there is a risk of seeing heavier showers. Probably not a complete washout but certainly could be better.
“The temperature very much depends on what sort of cloud we get. If we get the sun then low 20s are possible, but if it’s cloudier I think probably around 20 degrees or so. It’s going to be very much dependent on whether the clouds break a bit.”
In Manchester, where Dannii Minogue, Atomic Kitten and Little Boots will feature on Pride’s main stage, the weather should remain fairly dry throughout the afternoon, but it is likely to turn cloudy later.
“I would expect it to remain dry probably through the daylight hours,” Keates said, but added that there would be only limited sunshine.

“The main focus for thundery downpours looks limited to the south-east corner of England overnight but then becomes rather more widespread during Sunday afternoon and evening. A second yellow warning is in place for Monday, with heavier rains and stronger winds making it an unpleasant day in the south and south-east, and promising a repeat of last year’s carnival washout.
“Lightning may be an additional hazard. “We have got a developing area of low pressure, meaning the rains will pick up and the winds will strengthen,” Keates said. “I’d definitely pack a brolly. It’s looking like a greater risk of seeing some heavier, more unpleasant rain ... probably 17 or 18 degrees at best.”
“The public should be aware of the risk of localised impacts from heavy rain and flooding, which may affect travel and some outdoor events.” Manchester and the north-west are likely see the same kind of uncertainty as the south did a day earlier, but it could improve with some more brightness later in the afternoon. “Not a great day to be out,” Keates said.
Kent will be among the areas which could see heavy localised rain, weather forecasters MeteoGroup added.
Senior forecaster Clare Austin warned the rain would move north on Bank Holiday Monday into northern and eastern parts of England.
“Next week looks like an improving picture with only one or two showers around but it will be cooler,” she added.
