The Met Office has issued a yellow weather warning with rain set to buffet parts of the UK.
The national weather service has also named Storm Ciaran, which is set to bring further downpours.
Unsettled conditions are set to bring severe weather warnings in the early stages of the week before a further deep area of low pressure brings strong winds and heavy rain to southern parts of England and Wales.
Met office Deputy Chief Meteorologist, Chris Almond, said “Winds associated with Storm Ciarán are likely to gust to 80mph along the south coast of England, with a small risk of somewhere exposed seeing 90mph, and winds could even gust up to 50 or 60 mph further inland.
“This deep low-pressure system will also bring heavy rain to much of the UK, but the heaviest rain is expected in southern and western areas with 20 to 25mm quite widely across the region but up to 40 to 60mm potentially over higher ground.
“Heavy and persistent rain will fall onto already saturated ground bringing a risk of further impacts such as flooding in areas that are already struggling to clean up from the heavy rainfall we have seen over the last week or so.”
