Good morning and welcome to our extreme weather blog.
The UK is bracing itself for the hottest day on record on Tuesday, as forecasters said temperatures could reach 41C.
The mercury is set to rise higher than on Monday – already the hottest day of the year at 38.1C (in Santon Downham, Suffolk), though slightly short of the current all-time UK heat record of 38.7C. That record was set in Cambridge in July 2019 but could be broken today.
Rachel Ayers, from the Met Office, told PA Media Tuesday was going to be “unprecedented”. She said: “The temperature will be very hot throughout the day, before rising as high as 40C, maybe even 41C in isolated spots across England during the afternoon.
“This will make it the hottest day on record and the first time we have seen temperatures as high as 40C.”
Scotland and Wales could also see their hottest days on record. Holyrood minister Keith Brown urged people “to think about whether they need to travel and, if they do, make sure they’re properly equipped and plan their journey in advance”.
Travel routes will be affected by the heat and National Rail told customers only to travel if absolutely necessary. Network Rail said: “There will be delays, cancellations and last-minute changes to train services due to the unprecedented record heat on those days.”
There will be no Thameslink or Great Northern trains running anywhere north of London, from London Blackfriars via St Pancras, or from London King’s Cross or London Moorgate on Tuesday.
Merseyrail said the number of trains running and journey times will be “seriously affected”, with some routes closed completely. LNER will run no trains from south of York and south of Leeds to London King’s Cross.
Southern, South Eastern, South Western Railway and Great Western Railway are among the dozens of train companies running significantly reduced services across the country.
Transport for London (TfL) said London’s rail network would also be running a reduced service on Tuesday due to safety restrictions put into place to deal with the heat.
