The Met Office has issued yellow weather warnings for gusts of up to 80mph in parts of the UK ahead of Storm Gareth, with travel disruption likely throughout Tuesday and Wednesday.
The Severn Bridge connecting Monmouthshire to south west England was closed this morning, while train companies have warned speed restrictions may have to be used due to the strong winds expected over the next two days.
Falling trees and debris pose a threat to train tracks and roads, while some flights may be affected.
Storm Gareth is expected to cause the most disruption in Northern Ireland and Scotland first before spreading to the majority of England and Wales through Wednesday.
Heavy rain is also expected in the north-west of England and parts of Yorkshire, according to the Met Office.
South Western Railway said it may have to impose speed restrictions in coastal areas.
