As reported by Evening Standard, a yellow rain warning covering southern England will be in force until 9am as wet weather comes from the North Sea. The southeast is likely to be hit with a particularly wet start though things will be brighter elsewhere. There is expected to be showers in the west.
Met Office spokesman Craig Snell says the rain will clear in time for a sunny Christmas Day on Wednesday.
Mr Snell said: “We still have some rain to clear the east during Sunday morning.
“The worst of the rain will ease during the early hours.”
“It should have cleared into the North Sea by Sunday afternoon.”
Monday will be relatively dry but Tuesday will see more rain again.
Mr Snell explained: “By the end of Monday we will start to see more rain moving into Devon and Cornwall and this will move eastwards into Christmas Eve.
“But it starts clearing up for a dry Christmas Day.
"For many parts of the UK we are not going to see a white Christmas but there will be great spells of sunshine throughout the day."
There is a chance of a white Christmas in Scotland with lower temperatures expected.
Boxing day is likely to set a bit more rain and wind.
