Temperatures are expected to climb to 30C (86F) on Friday, rising to 32C on Sunday and 34C on Monday. In May the UK’s temperature record for that month was broken with highs of 35C. Amber heat health warnings, which mean there is risk to the wider population not just vulnerable people, have been issued by the UK Health Security Agency for eastern England, London , the south-east and the south-west from Thursday morning until Tuesday evening. Yellow alerts are also in place for the East and West Midlands. The Met Office said some areas in southern England are likely to see heatwave criteria met by Saturday and more widely on Sunday. Hot weather is deemed a heatwave when a temperature threshold is met three days in a row, which ranges from 25C to 28C across different parts of England.
