Hurricane Lorenzo to bring travel disruption, icy temperatures and 60mph winds
Freezing temperatures followed by 60mph winds are forecast as the remnants of Hurricane Lorenzo passes over the UK.
The Met Office is warning of transport disruption and power cuts in Northern Ireland, South West England and Wales on Thursday and Friday.
It said the storm, which is due to hit Northern Ireland on Thursday, is expected to bring heavy rain and wind speeds of up to 60mph in coastal areas.
It comes as the latest Met Office figures show that UK rainfall was 27% above average for September, with 122.4mm falling during the month, compared to the 96.4mm average.
Despite the downpour, the Environment Agency declared a drought in Hertfordshire and north London on Tuesday – when much of the country was experiencing flash flooding.
The Met Office said Wednesday is forecast to be dry for most of the UK, with some showers in northern and eastern coastal areas.
But temperatures are due to drop to freezing in some parts of England overnight due to the arrival of "cool air" from the north, Met Office spokeswoman Nicola Maxey said.
"Overnight on Wednesday, because we will have had this long clear spell, we might see some rural frost and temperatures drop to freezing in central and eastern areas," Ms Maxey said.
"However, this will be localised, it is not widespread."
Ms Maxey said Thursday is forecast to get off to a "bright start" for much of the UK, but added that cloud will begin to build up from the west as the storm arrives.
A yellow weather warning is in place from 3pm to 10pm on Thursday for Northern Ireland's coastline.
Wind speeds are forecast to reach 50mph and up to 60mph in the more "exposed areas" of the coast, Ms Maxey said.
She said the "relatively slow moving" storm – the most powerful ever recorded in the far east Atlantic – is due to hit Wales on Friday morning.
A yellow weather warning for strong winds is in place for South West Wales and South West England between 4am and 4pm.
The Met Office warns of "likely" delays to road, rail, air and ferry transport during that period.
Ms Maxey said: "We could see gusts of 60mph on the coast of South West England and South Wales."
She added that heavy rain is also forecast in those areas, with up to 20mm falling as the storm moves eastwards throughout Friday, eventually leaving the UK in the evening.
"As it (the storm) moves across the Atlantic it is weakening, and as it moves across England it will weaken," Ms Maxey said.
"That cloud and rain will push into the east, and then we will see brighter conditions begin."
Temperatures are forecast to reach 15C on Thursday and up to 18C on Friday.
The Met Office said rain is forecast for much of England and Wales on Friday, while Saturday is likely to be brighter with some scattered showers.
