A yellow warning for wind in the south is in place between 10am and 5pm on Monday.
A separate yellow warning for heavy snow and strong winds is in place for Northern Ireland and most of Scotland and a yellow warning of snow and ice is in force for North West England throughout Monday and Tuesday.
Met Office meteorologist Alex Burkill said: "While Storm Ciara is clearing away, that doesn't mean we're entering a quieter period of weather.
"It's going to stay very unsettled.
"We have got colder air coming through the UK and will be feeling a real drop in temperatures, with an increased risk of snow in northern parts of the UK and likely in Scotland.
"There could be up to 20cm on Monday and Tuesday and with strong winds, blizzards aren't out of the question."
Train passengers are being advised to check with operators before travelling as there are likely to be some cancellations to early trains as Network Rail engineers work through the night to assess the damage.
There are already numerous reports of rail disruption, including trains on the TransPennine Express between Preston and Edinburgh being suspended due to flooding at Carlisle.
Motorists are also warned to take care with continued disruption to the road network and tricky driving conditions likely to continue into rush hour.
