Britain is bound to be hit by 80-mile storms and floods on Friday, when meteorologists warn of "life-threatening".
The Met Office warned of "very strong winds" that could cause flying debris as well as large waves and beach material thrown on sea fronts, coastal roads and homes.
Extreme weather conditions could cause interruptions to road, rail, air and ferry services, with longer journey times and cancellations.
The worst conditions are expected to affect Scotland and parts of Northern Ireland, Wales and Southwest England.
A yellow weather warning was issued by the Met Office until midnight on Friday, with temperatures set to drop to -7 ° C.
Between two and five centimeters of rain are expected in the next 24 hours in some parts of the country.
A spokesperson for Met Office said: "Thursdays will be cloudy with rain and rain showers, which will then become drier and brighter in the north-western parts of the country this afternoon with some rains.
"On Friday, a deep low pressure system will bring strong winds and torrential rains to much of the country.
"It will be very windy with storms between the northern parts, stormy with heavy rains in the north-west of Scotland.
"On weekends, there will be showers or longer periods of rain for some Saturdays, remaining windy through the south.
"The winds settle down on Sundays and will be predominantly dry with isolated showers, bright periods for many and colder".
Despite its strength, the storm has not been named and is unlikely to be, according to the meteorologist.
The Met Office rained Saturday, windy south, before the weather cooled on Sunday.
