Ciara will be a familiar name for many people monitoring the storm in the UK, France, the Irish Republic and the Netherlands. But not so in other parts of Europe.
In Norway, the storm goes by the name of Elsa. In Germany and Switzerland, it's Sabine.
So why is this?
In recent years, several national forecasters have adopted the practice of naming large storms to help the public keep track of severe weather.
But while Irish, Dutch, French and British have agreed to adopt the same names, Germany and Switzerland have their own separate agreement, as does Norway.
