A RED warning for extreme heat has been issued by the Met Office.

The warning, which means exceptional temperatures will lead to widespread impacts on people and infrastructure, is set to come into force just over the Herefordshire border in Worcestershire and other parts of the Midlands and southern England on Monday (July 18) and will remain in force into Tuesday.

Herefordshire is still in an amber warning zone at present, with temperatures of 31°C forecast on Sunday, 36°C on Monday, and 38°C on Tuesday.

The Met Office said exceptional, perhaps record-breaking, temperatures are likely on Monday, then again on Tuesday.


Nights are also likely to be exceptionally warm for the UK, especially in urban areas. This is likely to lead to widespread impacts on people and infrastructure.

Temperatures are expected to drop away from Wednesday onwards.

What to expect?

  • Population-wide adverse health effects experienced, not limited to those most vulnerable to extreme heat, leading to serious illness or danger to life. Government advice is that 999 services should be used in emergencies only; seek advice from 111 if you need non-emergency health advice.
  • Substantial changes in working practices and daily routines will be required
  • High risk of failure of heat-sensitive systems and equipment, potentially leading to localised loss of power and other essential services, such as water or mobile phone services
  • Significantly more people visiting coastal areas, lakes and rivers, leading to an increased risk of water safety incidents
  • Delays on roads and road closures, along with delays and cancellations to rail and air travel, with significant welfare issues for those who experience even moderate delays
