The Met Office has said that a testing error is to blame for severe weather alerts warning of “a significant threat to life” which appeared on phones across the UK on Thursday.
Users across the UK received notifications warning of high temperatures, snow, ice and rain.
The Met Office, which is responsible for weather warnings, has said that a third-party aggregator issued alerts that were not intended to be seen by the public.
It confirmed that the test warnings had now been removed.
A Met Office spokesperson told the BBC: “We are aware of an issue where some test weather warnings were displaying on some websites and apps, we’ve worked with partners to ensure these test warnings have now been removed.
“We’re sorry for any inconvenience, there are currently no Met Office severe weather warnings in force as of 2pm Thursday 28 November.”
Many users posted on upcoming social media platform Bluesky about the issue, comparing their local temperature with the alert.
One said: “It’s frosty and 2 degrees here in #Manchester and the Met Office has issued us with a Severe High Temperatures alert.”
Another user suggested: “The Met Office site isn’t working because of unusual atmospheric conditions. Maybe someone could try spraying antifreeze on it and tuning up the engine for a few minutes.”
In October, the BBC’s weather website and app accidentally forecast hurricane-force winds hitting the UK.
Graphics showed estimated wind speeds of 13,508mph in London and overnight temperatures of 404°C in Nottingham.
