Raining on a reign: Forecasters warn of potential Platinum Jubilee thunderstorm weather alert

Thunderstorms could hit Jubilee celebrations from Wales to London on Saturday, weather forecasters have warned.

The Met Office is considering issuing a weather warning as it predicts heavy, possibly thundery, showers for parts of England and London on Saturday evening, during the Jubilee concert.

Wales will see a mostly dry Saturday morning but showers will inch their way into the southern parts of the country by the afternoon followed by a possibility of heavier, thundery showers into the evening.

The heavy rain forecast for London could dampen performances from the likes of Craig David and Alicia Keys at the BBC’s Platinum Party at the Palace on Saturday.

The forecaster is expected to review the situation on Friday morning.

Met Office meteorologist Simon Partridge said: “It’s being monitored but at the moment there’s not enough confidence to issue any warnings.

“But it’s one that’s going to be reviewed tomorrow morning as to whether or not we do require a thunderstorm warning, simply because of the number of people we’re expecting in the capital on Saturday night, so that’s one area of slight concern in terms of weather causing some issues for festivities.”

Mr Partridge said one of the main risks highlighted in a potential weather warning would be visibility on the roads and the impact on travel times for drivers.

He said: “I suppose it would be advice to take care or, at the very least, to leave extra time for journeys, because in those areas of rain, the visibility – because of the surface spray as well as just the rain on the road – will really mean you will have to reduce speeds.

“Certainly heavy rain with a risk of lightning and the usual associated risks there of some surface water issues, spray, poor visibility on the roads, and of course, if you are out, you are going to get wet.”

‘Wet’

Thursday brought highs of around 21C and 22C to Wales, with rain in places into the evening and Friday morning, before clearing up for sunny spells and patchy rain throughout the day with temperatures of 20C to 21C.

Mr Partridge said: “Sunday, Scotland will probably be the warmest place in the whole of the UK. We could very well see 23C to 24C down the west coast, which then would make that the warmest day of the year in Scotland so far.

“So if it does get too wet down in London then perhaps the Queen could go to Balmoral. It will be very nice, a fine end to the weekend there,” he added.

A total of 22,000 spectators are expected to attend the event outside Buckingham Palace, which is set to be broadcast live on BBC One, BBC iPlayer and BBC Radio 2.

The show will see appearances from stars including Sir David Attenborough, Emma Raducanu, David Beckham and Stephen Fry, as well as a specially recorded performance from Sir Elton John.

Diana Ross is also scheduled to close the two-and-a-half-hour show with her first UK live performance in 15 years.
