Storm Ophelia brought fresh chaos to Great Britain as it lashed parts of the country with winds of up to 77 miles per hour today.
The deadly storm has killed three people as it made landfall on Ireland yesterday, ripping off roofs, tearing down trees and whipping up waves.
More than 200,000 people were still without power today across the Republic and Northern Ireland today.
Scotland, Wales and parts of England were braced for disruptions and damage as the weather front moved eastwards on to the British mainland.
In Glasgow, part of a derelict block of flats partially collapsed at about 4am, and a scout hall roof was blown off in Dumfries and Galloway as the region took the brunt of winds up to 77mph.
Commuters were hit by cancellations and delays caused by the weather, with several rail lines blocked by fallen trees and other debris.
In Cumbria the county council said that high winds had torn the roof from a house in Whitehaven and even torn traffic lights from their poles, as well as causing traffic disruption.
Flood warnings are also in place along Scotland's west coast, with winds of up to 70mph expected, along with Wales' Pembrokeshire coast, north-west England, Cornwall and Dorset.
However, it was Ireland that took the worst of the storm.
Schools closed early, trees fell in roads, and bridges were shut as remnants of the hurricane battered Ireland and the UK's west coast - exactly 30 years after the Great Storm of 1987.
Among those killed was new father Fintan Goss ,33, who died when a tree struck his vehicle in Ravensdale, Dundalk.
In Cahir, Co Tipperary, a 31-year-old named locally as Michael Pyke was killed in a chainsaw accident when he was trying to clear a tree downed by the wind.
A woman in her 50s, named locally as oncology nurse Clare O'Neill, also died from a tree falling on her car near Aglish village in Co Waterford.
Prime Minister Theresa May "expressed her sympathies for the loss of life" in a call to Irish counterpart Leo Varadkar on Monday, Downing Street said.
About 216,000 Irish customers were still without power on Tuesday afternoon, and 80,000 people were cut off from water supplies.
People in the worst affected areas from Wexford to Skibbereen in Co Cork, have been asked to conserve their water supply as far as possible while repair work continues as reservoirs are re-filled.
Irish Defence Force soldiers have been deployed with vehicles and helicopters to help assess damage as thousands of staff from ESB, the Republic of Ireland's electricity network, worked to fix fallen and broken cables.
The Met Office said the storm's power will lessen when it hits Scotland and northern parts of England on Tuesday though an amber warning remains.
A yellow warning for high winds is in place for much of Wales, Scotland, north-east England, north-west England, south-west England and the West Midlands.
Planes have been grounded in many of the affected areas and ferries have been cancelled.
All schools in the Republic of Ireland and Northern Ireland will remain closed on Tuesday.
Help to restore the Irish power outages is expected to arrive from the UK on Wednesday.
Although no longer classed as a hurricane, the Met Office issued a "potential risk to life and property" warning while the RNLI urged people to stay away from the sea during the extreme weather.
"Stormy conditions may be tempting to watch but big waves can easily knock you off your feet," lifesaving manager Matt Crofts said.
Storm Ophelia is also thought to have caused a number of flights to UK airports to be diverted after "smoke smells" were reported on board.
EasyJet said four of its flights were diverted due to "atmospheric circumstances" linked to Storm Ophelia.
A British Airways spokesperson said the carrier has had "some reports of smells on board" but the aircraft continued to their destinations.
Planes flew in an unusual-looking sky as a red sun was spotted over parts of England on Monday.
It was caused by the former hurricane Ophelia pulling air and dust up from southern Europe and Africa.
