The UK weather is set to turn unseasonably warm this weekend and is predicted to stay that way right into next week.
Forecasters predict temperatures could reach as high as 20 degrees on Sunday, welcome news for holidaymakers on their autumn half-term break.
However there are fears that as the sun shines, people will hit the outdoors in their droves, causing widespread traffic congestion on the motorways through the weekend.
Train delays and crowded airports are expected as well.
The first Friday of the autumn half-term is quite often the busiest day of the year on the motorways.
Families will no doubt use the warm weather to enjoy the last holiday before Christmas.
Dan Williams of the Met Office said while most of Britain would experience mainly clouds – mostly in Scotland and the west – there would still be occasional spells of sunshine, particularly in the south east.
“On Sunday it will be fine and dry with unseasonably mild temperatures for this time of year, with London and South East reaching 20C,” Williams said.
“However, there will a risk of gales in exposed locations, and the weather will continue to be unsettled throughout the week, with a mixture of sunshine and showers expected in most regions.
“The rain will be heaviest in the West and South West, with strong winds expected but above average temperatures.”
