The weather warning is valid until 6:00pm on Thursday.
The storm is currently moving over northern isles off the coast of Scotland.
Grahame Madge, Met Office spokesperson said: "It's developing as we speak, meteorologically its development is quite complicated as it involves a number of low pressure systems.
"It's because of cold air coming out of the arctic which energises the system and deepens the system.
