Authorities are warning a new storm, named Conall, is forecast to bring heavy rain to southern England and Wales, hitting communities still cleaning up from Storm Bert.
The Met Office has issued yellow weather warnings for rainfall in several southern areas of the UK from 22:00 GMT on Tuesday until midday on Wednesday.
The storm has been named by the Dutch Weather Service, which along with the Met Office and Met Eireann in Ireland, name storms for ease of communication.
BBC Weather's Tomasz Schafernaker said the rain from Storm Conall would be "initially quite heavy", before moving east throughout the night.
But he added: "Here's the good news, the worst of the storm is expected to miss us.
"As it tracks across southern parts of the country, it's only just going to be developing, which means the worst of the weather will track across the North Sea and unfortunately impact the low countries."
On Wednesday, the rain band is expected to curl back, with Lincolnshire, the Peak District and the Midlands likely to experience wet conditions, Schafernaker said.
Coastal areas of Norfolk, Suffolk, Essex and Kent could also feel “near gale force” winds, he added.
In the north, frost is expected in Scotland and the Lake District.
Heavy rainfall and strong winds brought by Storm Bert over the weekend led to at least five deaths, while homes, roads and rail networks faced major disruption.
Many communities are still cleaning up after homes and businesses were inundated by floodwater.
Conall is the third 'named' storm of the season, after Ashley and Bert.
The storms list - first launched in 2015 - for each year generally runs from early September until late August the following year, coinciding with the beginning of autumn.
