How did Storm Herminia get its name and what comes next in 2025?

You may have heard (or noticed out the window) that the UK has been getting battered by Storm Herminia.

But it’s not actually an officially named storm – or at least, it’s not in the UK.

We haven’t skipped over Floris, which is the next storm due alphabetically after the Met Office officially named Storm Eowyn.

The current weather front was named by Spain’s meteorological office, andso we’ve adopted the moniker as the wind and rain made its way to us, even though the conditions are not strong enough to be classed as a stom in the UK.

Official storm names used in the UK are updated annually at the start of the autumn and winter storm season, generally running from early September until late August the following year.

We have used this system since 2015 to make communicating dangers from extreme weather simpler.

Storm Eowyn, which is thought to have been the strongest storm here for a decade, was the first named storm of 2025 but the fifth named storm of the 2024-25 storm season.

It brought record-breaking gusts of over 100mph in Scotland, while Ireland took an even bigger battering with 114mph recorded.

The UK Met Office works with the Irish Met Eireann in Ireland and Dutch weather service KNMI to pick the names, with a mix of popular names from each country.

Eowyn was Irish, and the next storm we get will be Dutch, taking the name Floris which means ‘flowering’, followed by a second Dutch name Gerben.

Soon after that will come Hugo and Izzy to fly the flag for England.

Met Office’s list of storm names

Other names that made this year’s list include James, Lewis, Mavis – allinspired by the Met Office’s 170-year history.

The forecaster said James is named after Group Captain James Stagg, who was the chief meteorologist responsible for advising General Dwight Eisenhower on the weather forecast for the D-Day landings.

Lewis comes from Lewis Fry Richardson, who devised a theory to use maths and physics to make weather forecasts using computers.

Mavis is named after Mavis Hinds, who worked on the earliest Met Office computers.

In the outgoing year, there were twelve named storms in alphabetical order.

It was the first time there were enough to get as far as the letter L, with Storm Lilian, so unless we have a particularly stormy year it’s unlikely we’ll get to see Storm Wren.

How do storms get their names?

Forecasters get to choose them, and the names often have some significance.

For example, Bert was put forward by KNMI (the Dutch national weather service) after they asked the public to come up with names at an event.

When the list was launched in August, Will Lang, who leads severe weather responses for the Met Office, said: ‘This year, as we celebrate our 170th birthday, it’s great to be able to honour those who have had an impact on our long history of pioneering weather and climate science services.’

Long before storms had official names, they were often identified formally by the places they hit, or by saints.

In the Atlantic, names rotate alphabetically, alternating between male and female. However, names beginning with Q, U, X, Y, and Z are skipped due to a lack of suitable names.

Some storm names become infamous for their death toll and huge impacts – such as Hurricane Katrina and Sandy in the US and Typhoon Haiyan in the Phillipines.

While it’s unlikely we’ll ever see storms causing that level of devastation in the UK, storm names linked to horrific events like the above are retired, to avoid confusion or emotional stress in future.

How do you pronounce Eowyn and what does the name mean?

The correct pronunciation for Eowyn is ‘ay-oh-win’ and you might be familiar with the name from a famous book and film series.

Eowyn is a character in J. R. R. Tolkien’s The Lord of the Rings and is a noblewoman of Rohan.

Tolkien is beleived to have invented the name by combining the words ‘eoh’ which means horse with ‘wyn’ meaning joy as in the series the people of Rohan are known as horse riders.
