Storm Austen made landfall in the south-west overnight and tracked eastwards through the day, bringing gusts of up to 84mph (135km/h) to Jersey. Guernsey recorded 76mph, which Paul Aked, head of Jersey Met, said was equivalent to a severe gale, force nine. Around 13,000 properties in the south-west were among those left without power.
Fallen trees blocked railway lines and roads, and National Rail advised that many routes were running at slower speeds. Ferry services between the UK and France were cancelled, Jersey Airport said flights would not operate until at least 17:00, and departure boards at Exeter airport showed multiple cancellations. Cornwall Airport Newquay advised passengers to check with their airline before travelling. In Horsham, a car was badly damaged by a fallen tree, although the driver was unharmed.
In Brighton, onlookers filmed a section of the West Pier falling into the sea as large waves pounded the structure. The pier, which opened in 1866 and closed to the public in 1975, had fallen into disrepair but remains a symbol of the city for some. Stephen Royle, who lives opposite the pier, said the waves were 'enormous' and that he was 'shocked' by how much of the structure ended up in the sea.
All schools on Jersey and Guernsey closed for the day, and some schools in Cornwall either closed or opened late. Families were evacuated from a holiday park in Perranporth, Cornwall, ahead of the worst of the storm on Thursday afternoon. Hannah Dawson-Turk, who was moved to a nearby hotel, told the BBC: 'The night before last, it sounded like our caravan was going to be ripped apart. The storm is very loud outside now, and the waves look huge from our windows.'
Mark Cox, boss of the Co-op on the Channel Islands, said fresh food shortages are expected in the coming days because ferry services have been suspended. 'It's rare we get this level of disruption to storms backing up so quickly and probably a little bit more heavier than what we've had to deal with in the past,' he said.
The UK should brace for more severe weather, with Storm Boelo forecast to bring strong winds and heavy rain on Saturday. The Met Office has issued an amber wind warning for much of Scotland, excluding the Northern Isles, as well as the far north of Northern Ireland and England, with gusts of 60 to 70mph expected and up to 80mph possible on exposed coasts. Yellow warnings cover Orkney, the rest of Northern Ireland and northern England, and heavy rain poses a risk of localised flooding. The Met Office advised people to drive cautiously, secure loose items such as bins and trampolines, and stay indoors where possible in coastal areas.
The storm arrived as the government released guidance recommending that households keep three days' worth of bottled water and tinned food to prepare for emergencies such as war, cyber-attack or natural disaster. Prime Minister Andy Burnham said: 'It's not about panic buying... It's about just taking sensible measures to have enough in the house to tide you over should there be a difficult situation.'
