Heavy rain is expected around Wiltshire for much of this weekend.
A yellow-level warning issued by the Met Office on Friday morning covers most of England and Wales and will be in place from 3pm on Saturday to 6pm on Sunday.
The spells of heavy rain are expected to cause disruption around the UK.
A spokesperson said: “Bus and train services will probably be affected with journey times taking longer.
“Spray and flooding on roads will probably make journey times longer.
“Flooding of a few homes and businesses is likely.
“Some interruption to power supplies and other services is likely.”
In Wiltshire specifically, the downpours are forecast to begin at around 5pm on February 17, with a 50 per cent chance of light rain.
This will increase to a 60 per cent chance by 7pm, then there is an 80 to 90 per cent chance of heavy rain from 8pm which lasts until 6am on February 18.
The showers are then expected to ease into light rain between 6am and 9am before the rest of the day sees dry conditions and cloudy skies, with the occasional bit of sunlight peeking through the cover.
Temperatures will range from 10 to 13 degrees Celsius on Saturday and seven to 12C on Sunday.
No flood warnings are currently in place, though 16 flood alerts indicate the possibility of rivers overflowing due to the hours of wet weather that are forecast.
This weekend's alerts cover the River Avon and the Semington Brook, the River Churn in Cerney Wick, the River Kennet and its tributaries from Berwick Bassett down to Newbury, the River Lambourn and its tributaries, the River Leach from Northleach to Mill Lane near Lechlade, and the River Thames and tributaries from Buscot Wick down to Kings Lock.
Flooding is possible at locations near the Bristol Avon, Tetbury Avon, Sherston Avon, Dauntsey Brook, with low lying land expected to be most affected, particularly around the road at Reybridge.
A government spokesperson said: "Please avoid using low-lying footpaths and any bridges near local watercourses and do not attempt to walk or drive through flood water.
"Plan driving routes to avoid low-lying roads near rivers, which may be flooded."
This comes after drivers ignored closure signs and drove through floodwater while alerts were in place for the area around Chippenham and Melksham last Monday.
