Severe weather warnings have been issued by the Met Office in Wales, the south-west, the Midlands, London, the south-east and east of the country.
The horrendous weather is the result of a deep area of low pressure from the Atlantic moving slowly north-east, bringing heavy rain and wind with it.
'What we are seeing is tight pressure gradients across the UK, meaning it is really windy,' Aisling Creevey, forecaster with MeteoGroup, said.
'Winds could reach up to 65mph across exposed coastal areas of Wales and south west and southern England.
'Across northern England, where the low pressure is moving over, winds are a bit more slack, and they are moderate across southern and central Scotland.
'But we could see winds of up to 50mph across northernmost Scotland and about 40mph to 45mph across the Northern Isles.'
The extreme weather could also see waves of up to 5.5m in the English Channel, while the heaviest rain is forecast for Wales, the Midlands and across western and northern England.
The south-west meanwhile will receive between 15mm and 25mm of rainfall.
The strong winds have already brought down trees, with a car crushed near Tavistock in Devon, although no one was injured.
The Environment Agency yesterday issued seven flood alerts, including one for all of Cornwall's coast and parts of south Devon, which warned of waves crashing over harbour walls, piers and seaside car parks.
Half-term holidaymakers were warned to take care on beaches and seafronts while ferries were also cancelled.
The first day of the England Test match at Edgbaston, Birmingham, was also a washout.
