Gales of up to 60mph and heavy downpours are due to hit parts of the UK as a yellow weather warning is in place from Tuesday.
The Met Office predicts wind will hit the west coast and Northern Ireland for 12 hours from 3pm.
A second identical warning is in place for south-west England and south Wales from 6am on Wednesday until the end of the day.
People have been warned to expect some delays to road, rail, air and ferry transport. It also states short term loss of power and other services is possible.
Meanwhile, much of the UK is forecast to be doused with sporadic showers throughout Tuesday and Wednesday.
Temperatures are predicted to range from around 11C (51.8F) in northern Scotland to 16C (60.8F) in the south of England during this period.
It comes as the Environment Agency has issued eight “flood alerts” for areas across England where flooding is “possible”.

Met Office deputy chief meteorologist Steven Keates said the worst of the wind and rain is expected on Tuesday afternoon and Wednesday.
He said: “There’s a distinct possibility of some disruptive wind for parts of the UK, especially in southern and western areas, as well as potential for heavy rainfall and even some snow, though the latter probably confined to high ground in the north.
“Although subject to a large degree of uncertainty, gusts of wind could be in excess of 60mph in some exposed upland or coastal regions, with around 35mm (1.4in) to 50mm (2in) of rain possible for some areas.”
This comes after temperatures dropped on Monday, following a balmy Easter Bank Holiday when the UK was hotter than Rome.
A high of 17.3C (63.14F) was recorded in Chertsey, Surrey – only slightly cooler than the hottest temperature of the year of 17.8C (64.04F), recorded in Santon Downham, Suffolk, on 30 March.
