The UK will bask in the hottest temperatures in nine years this week, with parts of the country set to reach a sizzling 36C.
But, while this is great for sun worshipers, the sudden increase in heat could cause serious travel problems.
Britain is on course to be hotter than California and experts have warned train tracks could BUCKLE and roads could MELT.
And who says the UK is never prepared for extreme weather?
The Weather Network told the Mirror: “Tomorrow [1 July] will be the hottest day of the year so far – with temperatures likely to peak at around 35C in the London area.
“This will make it the hottest day the UK has seen for nine years, when 36.5C was recorded at Wisley, Surrey in July 2006.”
While tomorrow is going to be hottest day, temperatures will remain in the high 20s for the rest of the week.
As well as travel problems, people are being warned to take care in the warmer weather to avoid health problems.
It’s important to regularly apply sun cream, keep hydrated and, where possible, stay out of the sun between 11am-2pm.
