The Met Office has issued an amber 'extreme heat' alert affecting 51 locations across four UK regions, as the country braces for a significant heatwave.
UK Regions Under Amber Alert
The alert covers the East of England, London and South East England, South West England, and Wales. It comes into effect at 1am on Monday, June 22, and remains in place until 11:59pm on Wednesday, June 23.
This follows an amber heat-health alert from the UK Health Security Agency (UKHSA) for the East of England, London, South East, and South West, along with a yellow alert for the East Midlands and West Midlands.
Expected Impacts
The Met Office warns of several potential impacts:
- Increased visits to coastal areas, lakes, and rivers, raising water safety risks.
- Adverse health effects for vulnerable individuals.
- Possible sunburn, heat exhaustion, and other heat-related illnesses for the wider population.
- Some delays to road, rail, and air travel, with welfare concerns for prolonged delays.
- Changes in working practices and daily routines likely required.
- Potential failure of heat-sensitive systems, leading to power cuts and loss of services.
Temperature Forecast
Met Office Deputy Chief Forecaster Greg Wolverson stated: "While heatwave criteria will be met for some in the south and southeast of England over the weekend, with temperatures into the low 30s Celsius possible, the warmth will expand and intensify at the start of next week. Temperatures will peak around the mid-30s Celsius on Monday and Tuesday. The humidity will also mean this feels close, warmer and more uncomfortable for many. Tropical nights – where the temperature doesn’t drop below 20°C – are also likely for some."
