London: Temperatures plunged below freezing in many parts of the UK on Sunday with heavy snow and gale-force winds causing major disruption to travellers.
The lowest recorded temperature was almost -5 degree Celsius in Perthshire overnight with "widespread" frost hitting large areas of the UK, the BBC Weather centre said.
Widespread icy patches could form on untreated surfaces, especially where snow has fallen. Drivers could face treacherous conditions on icy roads, the Met Office said.
The Met Office has also issued "yellow warnings" meaning "be aware" for ice in all areas and snow in eastern England from Lincolnshire northwards.
Heavy snow and gale-force winds caused major disruption to travellers across the UK with flights delayed, cross-channel ferries suspended and motorists stranded.
The north of England was worst hit by the cold snap with blizzards closing Leeds Bradford International airport in Yorkshire and Liverpool's John Lennon airport for several hours while flights at Manchester airport were also delayed yesterday.
The freezing weather also brought treacherous conditions to roads with many motorists in Sheffield forced to abandon their cars overnight after snow left roads impassable.
