Severe weather warnings remain in force for many parts of the British Isles, with further gales and heavy rain forecast overnight.
More rain is forecast to hit the country later in the week
Systems from the Atlantic are being blamed for two nights of storms.
Roads in south and west England have been closed, with winds up to 100mph recorded overnight in the West Country.
Areas in Northern Ireland and western Scotland are facing possible flooding, as the downpours feed water courses already swollen by recent rain.
Forecasters said conditions would improve slightly but southern Scotland, Northern Ireland and north-west England could still see severe winds overnight.
On Monday, the rain will sweep rapidly north-eastwards accompanied by strong south-westerly winds.
The Scottish Environment Protection Agency said areas most likely to suffer flooding were the western Highland region, west Perth and Kinross, Stirling, Argyll and Bute and Dumfries and Galloway.
In the south, however, the showers are expected to become less frequent overnight, with an expected sunny start to the day and above average highs of up to 13C.
Several roads were closed on Sunday including the Tamar bridge at Plymouth.
A coastguard from Cornwall was on his way to rescue a yacht crew whose vessel broke loose from its moorings when a tree fell on to his car. He cleared the road and completed his mission.
The Dover coastguard, meanwhile, reported ships reduced to walking speed at sea.
One of the main roads to the ferry port, the A20, was also closed, and Kent police advised cross-channel passengers to expect long delays.
"A deep Atlantic low brought the very stormy weather to the UK," said BBC weather presenter Daniel Corbett.
"The winds will ease across the northern UK on Monday.
"It should be a bright start in most areas before another area of rain spreads in from the west by afternoon but this next system will not be as nasty."
