Bonfire night set to be ruined by gale force winds and rain But the whole weekend will be breezy and feeling cold in the wind. Parts of southern England, from Cornwall to Kent, could also see heavy rain on Sunday. The Met Office issued a wet weather warning in London and South East England from 9pm on Friday until 3am on Saturday and a second in London, South East and South West England from 6pm on Sunday until noon on Monday. It comes after a chief fire officer warned people should move any bonfire night plans to Saturday night ahead of a four-hour strike by firefighters on Friday night. Richard Smith, chief fire officer for Mid and West Wales, urged people to "plan around having a bonfire night on Saturday night instead' of Friday because of the strike action. A spokesman for the Evironment Agency said: "Parts of southern and south eastern England are at increased risk of flooding from today and into the weekend. Southern England could see minor disruption from surface water and river flooding, including flooding of low lying roads and land and localised disruption to travel. There is also a risk of large waves affecting south and south west coasts of England, particularly in Dorset during Saturday evening and into Sunday morning.
