Extreme heat weather warning

The Met Office has issued its first UK extreme weather warning.


The amber warning covers much of Wales, all of south-west England, as well as parts of southern and central England.

It is likely to be in place until Thursday, when the high temperatures are expected to peak, before temperatures fall on Friday.

The warning advises that:

  • Adverse health effects are likely to be experienced by those vulnerable to extreme heat
  • The wider population are likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat related illnesses
  • More people are likely to visit coastal areas, lakes and rivers leading to an increased risk of water safety incidents
  • Some changes in working practices and daily routines likely to be required
  • An increased chance that some heat-sensitive systems and equipment may fail, leading to power cuts and the loss of other services to some homes and businesses
  • Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays
