A glitch in the BBC Weather website and app is leading to incorrect hurricane force forecasts in Britain and the rest of the world.

Charts show estimated wind speeds of 13,508 mph in London and 5,293 mph in Rome – far above any real hurricane like Milton that hit Florida overnight.

And temperatures of 404 degrees Celsius in Nottingham, 384 degrees Celsius in New York and 378 degrees Celsius in Sydney were among those incorrectly displayed.

BBC Weather said it was aware of a data issue with a third party supplier and was working hard to resolve the issue.

BBC News understands the disruption is mainly affecting wind speed forecasts.

Presenter Matt Taylor said in a post on There has been a data problem between our suppliers and the app/online. People are working to solve the problem.”

In another post, main presenter Simon King said: “Oops, don’t be alarmed by some data from our BBC Weather app this morning.

“Rest assured there will be no 15,000 mile per hour winds, hurricane force winds or nighttime temperatures of 1,000 degrees Fahrenheit.”

Forecasters have also acknowledged the problem in TV bulletins, which have not been affected by the outage.

In a statement, BBC Weather said: “We are having an issue with some weather data from our weather forecast provider, which is generating incorrect numbers and text on our BBC Weather app and website.

“It mainly affects the wind measurements, but some temperatures are also displayed incorrectly.

“We recognize that there is huge interest in weather these days and this is incredibly frustrating.

“We are truly sorry and we are working hard to resolve the issue.”

A BBC spokesperson also apologized and said it was working with its supplier to resolve the issue as quickly as possible.

Meteorological forecasting company DTN, which provides data to BBC Weather, said it was aware of the problem but did not know when it would be resolved.

A spokesperson for the US-based company said: “There has been an issue, but at this time we do not have an exact time when it will work again.”

In Edinburgh, the disturbance suggested wind speeds of 17,000 miles per hour. In Belfast it was suggested that wind speeds would reach 23,398 km/h, and in Cardiff it was said that winds would reach 20,585 km/h.

Meanwhile, Truro in Cornwall showed winds of 16,309mph and in Liverpool they were reported to be 15,227mph.

Forecasts currently also say that Paris will see hurricane winds of 21,322 km/h and Bangkok 21,491 km/h.

In reality, colder air will move in on Thursday, bringing rain and drizzle to southern Britain and heavy showers to the east coast.

According to the Met Office, gusts in Aberdeen will reach a maximum of 53 km per hour.

Next week, Hurricane Milton in Florida could bring uncertainty to Britain’s weather if its remnants enter the Atlantic Ocean, but the Met Office said it was “very unlikely” to reach the UK.

Hurricanes are powerful storms that develop over tropical waters.

These are sustained winds near the surface of at least 120 km per hour. In a Category 5 hurricane, the strongest on the Saffir-Simpson hurricane scale, wind speeds can exceed 155 miles per hour.

Hurricane Milton, which made landfall as a Category 3 storm, has ravaged Floridawith tornadoes, flooding and the risk of storm surges.

More than three million homes and businesses are without power, and “a number of deaths” have been reported on the Atlantic coast.
