The heat is likely to impact health and daily lives of those within the warning area
Parts of the UK are under an extreme heat alert with forecasters predicting near 40C temperatures. The Met Office has expanded an Amber heat warning into next week, which will likely impact residents of affected areas.
The alert is in place for Monday, June 22, until Thursday, June 25, and covers South East England and parts of Wales. The incoming heat is a result of band of pressure that is currently migrating from France. While the alert is not in place for Scotland, high temperatures of up to 30C are to reach the country next week.
Met Office Deputy Chief Forecaster Tom Crabtree, said: “The forecast heatwave is developing into an impactful severe weather event, with record breaking June temperatures and very high humidity. The combination of heat and humidity will be oppressive and bring impacts across society from public health and infrastructure, to power and water supplies.”
Temperatures will quickly rise on Monday morning (June 22) and are forecast to reach 34C in southern parts of England. heat will rise further into Tuesday (June 23), with highs of 37C forecast for southern England and 35C southeast Wales.
Conditions are set to peak on Wednesday and Thursday (June 24 and 25) when temperatures are expected to climb to 38C. By Friday conditions will be less hot, with highs of 33C forecast across eastern areas.
It is now likely the current highest temperature on record for June will be broken, this being 35.6C recorded in Southampton in June 1976 and Camden Square in June 1957.
Forecasters say that the heat will not be specific to day time, as “Tropical Night” temperatures are set to remain in the low twenties. The warning highlights potential health impacts for the wider population, not just those vulnerable to extreme heat.
Crabtree added: “As well as very high daytime temperatures, there will be consecutive nights where temperatures do not drop below 20C, which is called a Tropical Night. This will make it very hard for people to recover from the daytime heat, exacerbating the heat stress impacts.”
This extreme heat alert is not in store for Scotland, but residual warm air is set to move upwards, bringing scorching temperatures next week. The latest figures from WX Charts show areas in the north of Scotland reaching 26C by next Tuesday in Edinburgh and the east coast.
By Wednesday, temperatures are to reach 25C predominantly below the Central Belt. However by Thursday, the UK’s extreme heat will finally arrive in Scotland, with areas furthest south set to reach a sweltering 30C.
The Amber alert highlights the potential rise in water safety incidents due to resident seeking respite in coastal areas. Those heading to the sea should be mindful that surface temperatures are not as high as those seen in mid-summer. Sudden impact with cold water can lead to shock, which in turn raises heart rate and could trigger panic.
Samantha Hughes is the National Water Safety Partner at the RNLI. She said: “If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and it’s ok if your legs sink—everyone floats differently.
“Where possible, always choose a lifeguarded beach, and swim between the red and yellow flags. In a coastal emergency remember to call 999 for the coastguard.”
