The Met Office's yellow weather warning for much of England and Scotland came into force at 6am and is expected to run until 6pm on Sunday.
"The wind warning itself for the mainland UK ends at 6pm, but we can expect to continue to see quite blustery conditions even into the evening as the mainland rain itself pushes through.".
She added: "By the time people get up on Monday, we'll still have some of the residual rain from that front in the far south-east of the country, and quite cloudy across England as well.
Zoe Hutin, a meteorologist at the forecaster, said Sunday is expected to be the "worst day" before conditions improve.
Rain and strong winds are expected on Sunday - ending in a washout for large parts of the country.
