Storm Henk has hit large parts of England and Wales, bringing gusts of up to 81mph.
While the worst of the winds is said to have passed, a Met Office amber wind remains in place until 20:00 GMT.
The biggest gust of 81mph was recorded at Exeter Airport in Devon.
The winds also caused travel chaos, with several rail companies warning people not to travel as blocked trees were affecting much of the network.
In Orpington, in south-east London, a woman was taken to hospital after being struck by a falling tree.
A Met Office spokesperson said her injuries were not believed to be life-threatening.
According to UK Power Networks, more than 2,000 properties were affected by power cuts as of 19:00 GMT, although it is unclear how many of these were a direct result of Storm Henk.
There are widespread reports of flooding affecting roads and rail networks. As of 19:00 GMT there were 234 flood warnings in place, mostly in the Midlands.
Firefighters said they used an inflatable to rescue people from a car stuck in floodwater in Kenilworth, Warwickshire, in the early hours of Tuesday.
In Worcester, a woman in her 40s was rescued by passers-by from the River Severn on Monday and police in Leicestershire are receiving "a lot of reports" of crashes and breakdowns due to surface water.
Train services between London Paddington and south Wales are being diverted because of flooding between Swindon and Bristol Parkway, while the railway between Coventry and Birmingham International has been hit by flooding.
National Rail also said an electricity failure between London Paddington and Maidenhead had hit services between Paddington and Reading.
Thameslink has urged passengers not to travel unless absolutely necessary due to "multiple weather-related incidents across the entire network", while South Western Railway is urging people not to travel on its services because of "extreme disruption".
Train operator Avanti West Coast said in a post on X that overhead lines between Watford Junction and London Euston had been damaged - and warned of delays.
Southern Rail said it was enforcing speed restrictions of 40mph (64km/h) to multiple routes south of London.
And GWR has closed all services between Okehampton and Crediton in Devon after Okehampton station was damaged by the weather.
A yellow warning for rain is in place until 21:00, reaching as far north as Manchester and Hull. Another yellow warning for wind runs until the same time, stretching to just north of Birmingham and across the breadth of the country.
The Environment Agency has issued more than 150 flood warnings and more than 320 flood alerts in England.
In its warning, the Met Office said there was also a risk of flying debris causing "injuries or danger to life".
It added there was a good chance of power cuts which could impact mobile phone coverage.
It advises people living near the coast to avoid walking near large crashing waves as they may drag people out to sea.
Motorists should drive slowly and homeowners should secure garden furniture and other loose objects, the Met Office said.
BBC Weather's Matt Taylor said Storm Henk would move into northern mainland Europe by Wednesday but some showers and blustery conditions could still be around.
Henk is now the eighth named storm in only three months but this spell of wet and windy weather looks like it might come to an end later this week as more settled - but chillier - weather moves in.
The storm was named much later than usual - only hours before the impact was due to be felt.
This was down to its small size and because it was still developing early on Tuesday morning.
Early forecasts were for gusts of around 70mph but some computer models were suggesting a stronger swathe of winds, while others weren't - leading to uncertainty.
But as higher resolution models confirmed the potential for stronger wind gusts, there was greater certainty in the forecast and its potential impact.
An amber warning was subsequently issued, and the Met Office, along with the Irish and Dutch weather services, gave the small storm system a name - Henk.
Meanwhile, 2023 was provisionally the second warmest year in the UK since records began, the Met Office said. The warmest year on record was 2022. Global temperatures are rising mainly because of human activity, leading to more intense heatwaves and rising sea-levels.
