What is a Met Office red warning as rare heat alert issued for UK There is an increased risk of serious injury, ill health and even death The Met Office has issued a rare red weather warning for extreme heat in central and southern England and Wales on Wednesday and Thursday. The UK is set to bake in record-breaking temperatures which could soar to more than 38C as extreme heat warnings and health alerts have been issued. According to the Met Office, the sweltering heat could last until at least Thursday, sparking weather warnings and concerns for vulnerable people. Forecasters have said there is “growing confidence” this week could break the record for the hottest June temperature of 35.6C, which was set in 1976 in Southampton. The UK Health Security Agency (UKHSA) warned people to expect significant impacts across health and social care services along with a rise in deaths, particularly among those aged 65 and over or with health conditions. The extreme heat could also bring disruptions to rail, road and air travel, with the possibility of some tarmac melting, according to the Met Office. The Red Warning will be in place from 9am Wednesday to 9pm Thursday. The Met Office says you should: drink plenty of fluids, keep out of the sun and avoid any exercise between 11am-3pm when the sun is strongest and close curtains in rooms that face the sun. If you are going out take water with you, stay in the shade, wear sunscreen and a wide brimmed hat. A Met Office Red Weather Warning for Extreme Heat is the highest level of alert issued in the UK. It signals that a severe, potentially historic heatwave is occurring or imminent, posing a widespread threat to health, daily life, and infrastructure. What Does A Red WarningMean? The core message of a Red Warning is "Take Action." It is completely different from a standard "nice summer day" or even a standard amber warning. - Risk to Life for Everyone: Unlike lower-level alerts that primarily focus on vulnerable groups (like the elderly or infants), a Red Warning means even fit, healthy people are at risk of severe heat-related illnesses like heatstroke. - Widespread Infrastructure Failure: The heat is intense enough to cause Tarmac to soften, rail tracks to buckle, and power grids to fail. - Severe Travel Disruption: Significant delays, cancellations, and road closures are highly likely. - Tropical Nights: Temperatures overnight often remain incredibly high (above 20°C), meaning the body gets no chance to cool down and recover from the daytime heat. What Should You Do? When a Red Warning is issued, you need to change your daily routine to prioritise safety. Personal Safety & Health - Stay Out of the Sun: Avoid direct sunlight entirely between 11:00 AM and 3:00 PM, when the sun's rays and UV levels are at their absolute strongest. - Hydrate Constantly: Drink plenty of water even if you don't feel thirsty. Avoid alcohol, caffeine, or drinks high in sugar, as they can worsen dehydration. - Stop Strenuous Exercise: Postpone heavy physical activity, runs, or outdoor workouts until the warning is lifted. - Know the Signs of Heat Exhaustion: Watch out for heavy sweating, dizziness, rapid pulse, headache, and nausea. If someone shows these signs, move them to a cool place, get them to drink water, and cool their skin. If they don't improve within 30 minutes, or become confused or lose consciousness, call 999 immediately—this is heatstroke, a medical emergency. Around the Home - Keep the House Cool: Close blinds, curtains, and windows that face the sun during the day to block out the heat. Open windows at night once the air outside is cooler than the air inside. - Check on Others: Keep a close eye on isolated neighbours, family members, the elderly, infants, and pets who may struggle to regulate their temperature. Travel & Water Safety - Avoid Travelling: Do not travel unless it is completely essential. If you must drive, ensure your car has plenty of water, coolant, and a fully charged phone. Expect severe delays on trains and roads. - Take Care Near Water: If you go to a river, lake, or the coast to cool down, be extremely wary of cold-water shock. Open water in the UK remains deceptively cold year-round; jumping in suddenly can cause uncontrollable gasping and lead to drowning. Enter the water slowly, and if you get into trouble, remember to "Float to Live" (lean back, spread your arms and legs, and gently float on your back).
