Heavy rain is expected to bring disruption to parts of the UK with some areas facing the risk of flooding.
A Met Office yellow weather warning for "persistent heavy rain" is in place for parts of Wales and South West England until 5pm on Thursday.
People are being warned of transport delays and disruption to power supplies, with the possibility of flooding to some properties.
Communities could become "cut off by flooded roads", the Met Office said.
It added that "some higher ground areas may see 70-90mm or more" of rain.
Across the UK, the Environment Agency (EA) had issued 52 flood warnings - meaning flooding is expected - and 154 flood alerts - where flooding is possible, shortly after 11am on Thursday.
Saturated ground caused by recent wet weather means that even areas which have avoided the worst of recent heavy rain could be at risk of flooding.
People are being urged to "stay away" from "swollen rivers" and not attempt to drive vehicles through floodwater.
The EA has been erecting flood barriers at several of the most at-risk sites.
This has included the Worcestershire town of Bewdley, which has previously experienced flooding from the River Severn.
Mark Garratt, flood duty manager at the Environment Agency, told Sky News the "continued heavy rainfall" in parts of the Midlands and South West England "means that minor localised surface water and river flooding is probable" with the impact "potentially continuing" throughout the week.
He added: "With the ground already saturated, communities in these areas should check their flood risk.
"The Environment Agency is monitoring flood levels, operating flood gates and barriers at locations across the country, and ensuring debris screens are clear from blockages to ensure communities are better protected.
"We advise people to stay away from swollen rivers and urge people not to drive through floodwater as just 30cm of flowing water is enough to move your car."
Forecasters have said Thursday should be mostly mild but windy, with the prolonged rain in the south in contrast to showers elsewhere.
