The Met Office has issued yellow weather warnings because this weekend’s weather will be disrupted by ‘unseasonal’ strong gusts and heavy rain.
‘Disruption’ is anticipated to occur throughout Friday in South Wales and southwest England due to winds that could reach 50 mph.
The other alert has been issued for the eastern region of England, where Saturday is expected to be a “unseasonably windy day.”
Driving conditions and public transport could be affected.
The Met Office said: ‘Two yellow National Severe Weather Warnings or wind have been issued highlighting the potential for impacts such as travel disruption to South Wales and southwest England on Friday and the south and east of England on Saturday.’
Heavy rain will also sweep northeastwards on Friday morning.
Thunder is also possible, particularly in the west of the UK.
Paul Gunderson, chief meteorologist at the Met Office, said: ‘Strong winds will develop across the South West early on Friday, pushing further north across parts of Wales through the day.
‘Gusts of 35 to 45mph are likely quite widely for a time, with gusts over 50mph affecting some coasts and hills, mainly across Cornwall and west Wales.’
Temperatures will remain on the cooler side, with highs of 20C on Friday and 21 on Saturday.
Mr Gunderson said: ‘This is an unusual time of year for such strong winds and, with many people on holiday or planning outdoor activities, they are likely to cause some disruption.
‘In addition, heavy rain could lead to standing water and spray on roads and consequently difficult driving conditions. Winds are expected to ease through the evening.’
