This level requires social and healthcare services to take specific actions to help high-risk groups. Conditions in other areas of England and Wales may come close to triggering a higher alert but it is less likely.
The very young, elderly and seriously ill are groups particularly at risk. Much of the UK has been basking in hot weather for more than a week.
While the warm weather has been welcomed by sunbathers, sport watchers and barbecue fans, the heat can be dangerous for the very young, elderly and seriously ill.
The "Level 3" amber warning is part of the Heat-health watch system, which is intended to put health, housing, social care and other public bodies on alert in case of a heatwave.
The trigger temperatures that will see local plans put into action to protect those susceptible to the heat vary depending on where you live.
In north-east England it is 28C, in Wales 30C and in London 32C. The night-time trigger temperatures vary from 15C to 18C.
