Met Office in 46-hour power cuts warning for 51 UK areas from Monday - full list

Met Office in 46-hour power cuts warning for 51 UK areas from Monday - full list The Met Office has issued an amber extreme heat warning across 51 areas, with temperatures set to reach the mid-30s and trigger possible power cuts to homes and businesses The Met Office has issued a severe amber weather warning for extreme heat starting from Monday across 51 areas of the UK - and has cautioned that the scorching conditions could trigger power cuts. The weather experts have warned that "extreme heat" will mainly affect the south of England and Wales from 1am on Monday, lasting 46 hours through to 11pm on Tuesday night. Temperatures will soar into the mid-30s in Celsius, with overnight lows remaining as high as 20C, the Met Office said. The forecaster warned that the sweltering conditions could cause "heat sensitive systems and equipment" to break down, resulting in "power cuts and the loss of other services to homes and businesses". It said: "A developing hot spell is expected to peak on Monday and Tuesday and lead to widespread impacts on people and infrastructure." "Following very warm weather on Sunday, very high temperatures are expected on Monday and Tuesday and will likely bring widespread impacts to people and infrastructure. In addition to high daytime maxima, temperatures overnight will remain very warm, especially in larger urban areas, and it will also feel humid. "Temperatures are likely to reach the mid-30s Celsius in places on Monday and Tuesday. Some places, particularly in urban areas, may see temperatures remain above 20 Celsius overnight. "The very high temperatures may continue across a smaller area into the middle of the week, but there remains some uncertainty regarding the extent of this." During the previous record-breaking heatwave , from May 24 to 31, the UK saw a horrifying death toll of 19 children and adults killed in water related incidents during one week. In response the Mirror launched our 'Save Lives for Sam' campaign to stop the "catastrophic" deaths of 33 children who drown in England every year - "the equivalent of a classroom of children lost". Bereaved families, Olympic legends and safety organisations have joined together to call on the Government to take five key steps to save young lives across the country. People heading to the coast in the coming days should be mindful that sea-surface temperatures are not as high as they would be in mid-summer, the Met Office warned. Samantha Hughes is the National Water Safety Partner at the RNLI. She said: "With warmer weather approaching, it's important to remember that the water is still cold. Entering it unexpectedly can lead to cold water shock, causing a sudden increase in breathing and heart rate, which may trigger panic. "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."
