Storm Ernesto formed in the North Atlantic near the east coast of America on Tuesday and has since been travelling across the ocean at around 40mph.
It is set to arrive on the UK in the early hours of Sunday morning, but will only hit certain areas.
Northern Ireland, Scotland and western England, including Lancashire are all expected to feel the effects of the severe weather.
According to the Met Office, Storm Ernesto will no longer be classified as a storm when it arrives in the UK, due to it losing some of its power as it heads across the body of water, but it will still impact on the UK with heavy rain and strong winds.
