“The winds will be particularly strong in the northwest, especially for western Scotland where we could see gusts of 70 to 75 mph.”
The rain on Sunday will be heavy and persistent throughout the day and into the evening.
The meteorologist added: “That rain again turning heavier through the evening time particularly over the hills across Wales and Southwest England and into Northern England as well.”
The Met Office Deputy Chief Meteorologist, Martin Young, said the second weather system set to come on Sunday will contain the “remnants of ex-Hurricane Zeta” which will bring the further heavy rain and strong winds.
But as Britain heads into next week, the weather looks to be more promising.
Monday is expected to bring drier conditions but cooler temperatures are also set to sweep over the UK.
The Met Office meteorologist said: “There’s still some more wet and windy weather to come this weekend but looking ahead to next week it could be a bit drier and a bit colder too.”
They added: “Looking ahead to the end of the week and into the start of next week, rain will clear away on Monday.
“We’re left with breezy conditions and scattered blustery showers Monday and Tuesday before Wednesday high pressure starts to building and that could mean a spell of drier and colder weather with more widespread frosts.”
