You may have seen parts of the UK are being told to prepare for a battering from Storm Floris.

The real weather enthusiasts among you might have noticed something odd about this name: aren’t storms named alphabetically? And wasn’t the last one Storm Herminia?

That’s a very astute observation,but there’s a very sensible reason for the discrepancy – and it’s not because H comes before F in the meteorological alphabet.

Storm Floris was always going to be the next storm due after the Met Office officially named Storm Eowyn.

But Herminia was named by Spain’s meteorological office,and so we adopted the moniker as the wind and rain made its way to us,even though the conditions were not strong enough to be classed as a storm in the UK.

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.
