Large parts of England have been placed on heatwave alert, the first time Public Health England has ever issued a warning in September.

Hot and humid weather is forecast for the next few days in the East of England, the South East, London and the East Midlands, and all were put on Level 2 alert.

A heatwave alert is triggered when the daily maximum is expected to exceed the average by 9°F (5°C) for more than two consecutive days.

Temperatures are expected to reach around (82°F) 28°C in the south east on Tuesday, and London could see temperatures over 86°F (30°C). Even in the South East, the average September maximum is only 66°F (18.9°C) so the soaring temperatures are well beyond what is needed to trigger a heatwave.

The current heatwave warnings have only been in place since 2012, but this is the first September warning so far.
