Some may be but not the majority, according to this article it's the public.
How are storms named?
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.
However, for the 2023-24 season, the Met Office has altered this, naming a number of storms after prominent scientists, meteorologists and others "who work to keep people safe in times of severe weather".
What names are on this year's list?
When the criteria for naming a storm are met, either the Met Office, Met Éireann or Dutch weather agency KNMI can name a storm, taking the name from the latest list in alphabetical order.
Jocelyn was named by Met Éireann after Prof Jocelyn Bell Burnell, an astrophysicist who discovered the first pulsating radio stars, or pulsars, in 1967.
Isha, pronounced ee-sha, was suggested by a member of the public.
A total of seven names in the 2023-24 storm season were selected by KNMI - including Henk which was submitted by someone who visited an open day at the agency's headquarters in October 2022.
