Storm Floris expected to hit parts of UK after weekend
Matthew Lehnert, a Met Office Chief Meteorologist, said: “Across the warning area, many inland areas are likely to see gusts of 40-50mph, with 60-70mph more likely at higher elevations and around exposed coasts in Scotland.
“There is a small chance that some locations here could even record gusts of 85mph.”
How do storms get their names?
While the Met Office shared that this storm will be called Floris, it hasn’t revealed the reason behind it.
Storms in the UK are always named by the Met Office “when it has the potential to cause disruption or damage”, reports the BBC.
This is because the weather service thinks giving a storm a name makes it more recognisable when talked about on TV, radio and social media.
The BBC explained: “The UK Met Office and Irish service Met Éireann launched their first “Name our Storms” campaign in 2015.

“Most years, they draw the names from a shortlist of favourites submitted by the public. Since 2019, they have been joined by the national weather service of the Netherlands, which also chips in a few suggested names each year.
“In previous years, storms have alternated between male and female names.”
The 2023-24 season saw a change to this method though as some storms were named by scientists and meteorologists plus other people who help people stay safe during serious weather conditions.
