Storm Nelson hit Britain today with 80mph winds, snow, heavy rain, hail and thunder as parks were closed, ferries cancelled and rail operators warned of delays.
The Met Office extended a 17-hour wind warning to cover the whole of England's south coast from Cornwall to Kent and up to Suffolk with strong gusts until midnight.
DFDS had to cancel some ferries from Dover to Calais and Dieppe to Newhaven, while Thameslink warned rail passengers that the winds could delay trains today.

Dartmoor Zoo in Devon shut because of the winds, while National Trust sites such as Needles Old Battery and Mottisfont Gardens in Hampshire also had to close.
Some snow even fell in parts of Devon and Wales overnight - after accumulations also built up at the other end of the UK in the Scottish Highlands earlier this week.
Nearly 3in (8cm) was recorded this morning at Sennybridge in Powys, while 2in (5cm) settled on the ground overnight at North Wyke, just north of Dartmoor.

The weather system has been named Storm Nelson by Spanish meteorologists in what could be seen as an ironic gesture about Britain's victorious vice admiral as it heads for our shores.
It is the UK's first named storm since January but the 11th of the current season, which began in September.
Today's weather warning, issued by the UK Met Office, predicts road, rail, air and ferry disruption, as well as cuts to electricity and mobile phone networks.
Forecasters added: 'There is a small chance that injuries and danger to life could occur from large waves and beach material being thrown onto sea fronts, coastal roads and properties.'

Describing the weather, the Met Office said: 'A deep area of low pressure will bring a spell of very windy weather to parts of southwest and then southern England on Thursday.
'Gusts of 50 mph are expected quite widely, while some exposed coastal spots may experience gusts of 60 to 70 mph, with large waves also likely.
'The strong winds will be accompanied by heavy, squally showers with the possibility of hail and thunder in some locations.
'Hail won't fall everywhere but where it does it can quickly make road surfaces slippery, while surface water and spray are likely to worsen travel conditions rather more widely.'

Further north, a separate band of cloud and showery rain will bring damp conditions before clearing this afternoon - followed by more rain later as Nelson moves north-eastwards.
The Met Office added that showers are due to continue into Good Friday, when it is due to be bright and breezy.

Temperatures in southern England on Easter Sunday could reach highs of 15C (59F) - warmer than the Spanish capital Madrid, which is due to be cool and showery with temperatures of just 10C (50F) on Easter Sunday.
