Mr Barclay said: “The clear message to the public is to take the sensible steps around water, shade and cover, which many people are aware of. This is the best way to cool off from the heat. “We are asking people to look out for their neighbors and those who may be vulnerable. “We also offer additional emergency support.” He added: “We will put extra measures in terms of call handlers, fleet support [and] additional hours of capacity within the ambulances. “Every ambulance trust has well-developed emergency plans for extreme weather events. “We’re also working with hospitals to get ambulances into hospitals, but also to make sure that where people can be taken to wards themselves, we’re using the full capacity of the hospital instead of people waiting longer than they have to be ambulanced out ». An orange warning has been put in place before some areas of England are placed under an unprecedented ‘red’ warning.

Martin Berry, Chief Paramedic Officer, said: “Some of the things we end up seeing in this type of weather is people suffering from heat stroke, dehydration, the elderly and the vulnerable may not necessarily be drinking as much water as they need. you might be sitting at home not being able to open the windows and it getting very hot. “We also see young children suffering from dehydration as well as burns when they are dragged around in hot yards, so it is very important to keep these people safe and drink plenty of water.” Weather presenter Sally Williams explains what heat waves are and what you can do to stay cool Ministers held a virtual emergency Cobra meeting on Saturday after forecasters warned record high temperatures could put lives at risk. Cabinet minister Keith Malthouse, who chaired the meeting, said transport services would face “significant disruption” on Monday and Tuesday and urged people not to travel. He added that schools are being issued with instructions so they can remain open. Met Office climate performance scientist Dr Nikos Christidis said the 40C forecast is a result of climate change. “We were hoping we wouldn’t get to this situation, but for the first time we’re forecasting over 40C in the UK,” he said. “In a recent study we found that the likelihood of extremely hot days in the UK has increased and will continue to increase over the course of the century, with the most extreme temperatures expected to be seen in the south-east of England.” The weather forecast across the UK Meanwhile, the Met Office has forecast dry weather for Wales, the Midlands, the South East and South West England on Sunday as temperatures soar to 31C.
