What does the yellow health warning for heat in England mean?

The UKHSA has issued a yellow weather warning for heat for between 8am and 5pm from Monday until Thursday (June 24 - 27).

A yellow warning indicates heat that will mainly affect people who are vulnerable. People can still continue their daily routine but there may be impacts on travel.

Particularly, The agency warns the heat is likely to put stress on NHS services and there is a greater risk of ill health for the country’s “vulnerable population.”

These include an "observed increase in mortality across the population likely, particularly in the 65+ age group or those with health conditions, but impacts may also be seen in younger age groups", the UKHSA said.

The health warnings are rated from green (no warning) to yellow, amber and red, which would indicate a huge risk to life.
