Forecasters say high winds could hit coastal areas along the English Channel later today.
The Met Office says an unseasonably windy spell is likely across many parts of the UK later on Monday, overnight and well into Tuesday, as active frontal systems sweep across the UK.
The Yellow Warning is valid from 2pm today until 6pm on Tuesday, 2 June.
Forecasters said an initial swathe of southerly gales accompanied by heavy rain will move east across many parts later on Monday, giving gusts of 40-50 mph widely but 60-70 mph across exposed Irish Sea and perhaps some English Channel coasts.
A Met Office spokesman said: ‘Winds will become west or southwesterly on Tuesday, with further gusts to 40-50 mph more locally, before gradually easing later.
‘Large waves will affect some coasts in the west and south at times.
‘Given the unseasonable nature of the winds, the public should be aware of the potential for disruption to transport and outdoor activities.
‘This is due to a powerful jet stream stretching across the Atlantic into the UK will steer a number of active weather systems across the UK during Monday and Tuesday.’
