Winds of up to 60mph are battering England and Wales while heavy rain threatens flooding.
The Met Office has issued weather warnings for wind across south-west England, the Midlands and the South East, and for wind and rain in Wales.
Flood warnings and alerts are in place for Wales and southern England as the weather system moves east.
In Cornwall, three people escaped unharmed after their car was crushed by a fallen tree.
Winds could reach 40 to 50mph inland, with the south Wales coast, the Bristol Channel and the south coast could see gusts of up to 60 mph.
More exposed areas could see gusts of up to 65mph with the threat of some disruption such as fallen trees.
BBC weather forecaster Laura Gilchrist said: “This weather would not be unusual in October or November, but as it’s coming in June the trees are more in leaf and people are carrying out more outdoor activities than then, so there’s more risk of disruption than at other times of the year.”
There is also the potential for high waves as the wind funnels through the Bristol Channel.
Met Office spokesman Charlie Powell said: “It is possible there could be up to three inches of rain in hilly and mountainous areas of Wales, with lower but still substantial rainfall in more low-lying areas.”
There is brighter news for the weekend, as the weather is set to improve for Saturday, feeling much warmer and with sunny spells.
The positioning of the jetstream is to blame for such wintry weather in June, Ms Gilchrist said.
“It should be further north, it’s taken a little bit of a dip south, which is allowing weather systems to develop across the UK, but it has the potential to move back again,” she said
