The Met Office has issued a rare red weather warning for extreme heat, with temperatures forecast to reach 40°C in parts of the UK. The warning, the highest level, indicates a danger to life and covers large swathes of England from London to Manchester.
Record-Breaking Temperatures Expected
Forecasters predict temperatures could soar above 38°C, potentially breaking the UK record of 38.7°C set in Cambridge in 2019. The Met Office warned that the extreme heat could lead to serious illness or danger to life, not just for vulnerable people but for the wider population.
Health alerts have been issued across the country, with the UK Health Security Agency (UKHSA) raising its heat health warning to the highest level. The public is advised to avoid travelling, stay indoors during the hottest part of the day, and check on vulnerable neighbours.
What the Red Warning Means
The red warning is the most severe weather alert issued by the Met Office. It is only used when extreme weather is expected to cause widespread disruption, damage, and risk to life. The last red warning for heat was issued in July 2022, when temperatures hit 40.3°C in Coningsby, Lincolnshire.
According to the Met Office, the warning is in place from Monday to Tuesday, with the highest temperatures expected on Tuesday afternoon. The public is urged to take immediate action to protect themselves and others.
Impact on Transport and Infrastructure
Network Rail has warned of potential speed restrictions and delays on train services due to the heat. The RAC has advised drivers to check their vehicles before setting off, as extreme heat can cause breakdowns. Airports have also warned of possible delays as tarmac softens and aircraft performance is affected.
Schools in affected areas are considering early closures, and outdoor events have been cancelled or postponed. The government has activated its emergency response plan, with COBRA meetings scheduled to coordinate the response.
Advice for the Public
The UKHSA recommends staying out of the sun between 11am and 3pm, drinking plenty of water, and wearing light, loose-fitting clothing. People should also avoid alcohol and strenuous exercise. The public is advised to close curtains and blinds in rooms that face the sun and to keep windows shut during the day to keep rooms cool.
NHS England has warned that emergency services will be under significant pressure and urged people to use 111 for non-life-threatening conditions. The red warning is expected to remain in effect until Wednesday, with a gradual cooldown later in the week.
