More than 3,000 properties are without power in Devon and Cornwall amid strong winds.
A Met Office yellow warning for wind was in force in Cornwall until 11:00 GMT, while a separate yellow warning for rain is in place in both counties until 06:00 on Monday.
National Grid said more than 2,000 properties in Cornwall and more than 1,000 in Devon were without power.
A gust of 79mph (127km/h) was recorded in St Mary’s in the Isles of Scilly.
A Ryanair flight that was expected to land at Cornwall Airport Newquay at 07:35 was diverted to London Gatwick, with other flights delayed, said the airport.
At Exeter Airport flights to and from Belfast and Jersey have been cancelled.
On the roads a fallen tree has blocked the A39 at Falmouth Melvill Road, between Holywell Road and Mill Lane and westbound at Camelford.
A tree has also fallen in the north-bound carriageway of the A380 Telegraph Hill, said Devon Highways.
National Rail said there would be no trains to and from Newquay until about 13:00 GMT.
The strongest gusts so far have been recorded in St Mary’s in the Isles of Scilly 79mph (127km/h) and at Berry Head in Devon 68mph (109km/h).
Much of Cornwall is gusting over 60 mph (96km/h).

Tamar Bridge was closed to high-sided vehicles but it has since reopened, Tamar Crossings said on X.
Maggie Howell from Falmouth Coastguard said people should stay away from coastal areas.
“Further out at sea it might have had worse conditions, but it’s looking really, really bad out here this morning,” she said.
“Don’t go trying to go wave watching or anything like that because not only are you risking yourself, you’re also risking the people that will come out and try to help if you get into trouble.”
Great Western Railway is advising passengers to check before they travel and take extra care while travelling to and from stations.
Devon Highways advised drivers to be alert for any fallen trees and potential flooding.
Andy Cole, from Devon Highways, said: “On our minor network there’s a bit of risk on those corners, those blind bends where you come across some debris, a tree branch or even a tree or flood water.
“We just ask the drivers to take extra time, to take extra care and just be aware of what could be around the corner.”
Paddy Cochran, also from the coastguard, added: “We’ve seen the destructive force over the last couple of days, with a number of caravan parks getting properly smashed and all these kind of mini tornadoes running through villages and stuff like that, so just exercise caution and no unnecessary risk please.”
On Monday, it is expected the winds will once again pick up, potentially gusting 60-70mph (96-112 km/h) for the duration of the day.
