Bank Holiday Monday is set to be a washout as weather forecasters have said heavy rain and strong winds of up to 40mph will spread across the UK.
The Met Office has warned that motorists should take caution as surface water and spray on roads could cause problems.
A yellow (be aware) warning has been issued and the Met Office says: "Heavy rain is expected to affect many southern areas of Britain at times during Bank Holiday Monday, with strong winds a possible additional factor close to southern coasts."
It adds that "rainfall amounts look like exceeding 20mm quite widely, while a few places might see around 40mm, so there will be a lot of surface water and spray on roads.
"The spray will probably be made worse by strong winds across some southern area; gusts to around 40mph may occur at some coastal locations although this will depend on the exact track of the low pressure."
According to The Guardian, temperatures will struggle to reach above 17C – well below average for August. Scotland, where is not a Bank Holiday, will see the best of the weather on Monday.
Sunday's weather is expected to be largely fine across Britain, with sunshine and highs of 18C.
Tourism agency VisitEngland told the BBC that more than five million people were planning an overnight stay over the holiday weekend.
