Britain will be hit by 75mph gusts and up to two inches of rain over a 21-hour period from tonight after Storm Benjamin was named.
The Met Office warned the wet and windy conditions may cause travel disruption, flooding, power cuts and damage to buildings within the alert areas.
A yellow weather warning for rain covers most of southern England, the east Midlands, parts of Wales and Yorkshire and is in place all of tomorrow until 9pm.
Those within the affected regions have been warned to expect heavy rainfall from this evening with up to 50mm (2in) in some areas by early tomorrow morning.
Some areas, particularly North Devon, Cornwall and in the East of England, could exceed this amount of rain, meteorologists added.
The downpours may cause disruption to public transport, difficult driving conditions because of spray and road flooding as well as the flooding of homes and businesses.
A separate warning for wind tomorrow is in place from 9am until 11.59pm, covering the east of England up to Scarborough where gusts of up to 75mph may develop.
For the majority of the yellow alert area, gusts of up to 55mph are expected with 65mph possible near coasts, the Met Office said.

Strong winds may lead to power cuts, transport disruption and damage to buildings with a small chance of injuries and danger to life caused by large waves and beach material being thrown onto seafronts and coastal roads, the forecaster warned.
Another yellow alert for wind tomorrow covers South West England and parts of Wales, including Somerset, Devon, Cornwall, Swansea and Pembrokeshire.
Gusts of up to 45mph are expected widely within this area, while winds of up to 60mph could be reached along exposed coasts and headlands.
Met Office meteorologist Aidan McGivern said some ‘very unsettled weather’ caused by low pressure was expected from tonight into tomorrow.
He said: ‘The low is deepening as it crosses the UK, it’s likely to bring a swathe of strong winds as well, gales around southern and eastern coasts, the risk of 60mph gusts in some exposed spots, perhaps even a touch more in places.’
Before today, conditions are expected to be a ‘mix of bright spells and showers’, he added.
RAC spokesman Rod Dennis said: ‘Thursday is set to be a challenging day for drivers, with the evening commute likely to be a very wet and windy affair for many.
The Met Office said a strengthening arm of the jet stream – a fast moving ribbon of air high up in the atmosphere – has the potential to develop a deep area of low pressure by Thursday
‘We urge drivers to slow down according to the conditions, leaving a much bigger gap between themselves and the vehicle in front, and be wary of the buffeting effect of the wind when they pass high-sided vehicles.
‘On more rural routes, flooding is a very real possibility so drivers must never be tempted to risk it by driving through standing water unless they’re confident it’s shallow enough to get through safely – it’s always better to turn around and find another route.
‘Those taking to the roads on Friday should also be extra vigilant, as branches and other debris may have been blown onto roads – another reason why driving more slowly in these sorts of weather conditions is so important.’
The impact of Storm Benjamin is set to be strongest in northern France and Belgium, and it was named today by Meteo France – rather than the UK’s Met Office.
The next storm on Britain’s list is Storm Bram, after Storm Amy – the first storm of the 2025/26 season – hit north-western parts of the country in early October.Â
