UK Weather: A third UK heatwave is increasingly likely as temperatures of 30C are forecast.

Later in the week, however, southerly winds may raise temperatures slightly, but there is much uncertainty around this.

The UK’s Health Protection Agency has issued yellow heat health alerts for the East Midlands, East England, London, the South-East and the South-West, warning that there is a greater risk to the lives of vulnerable people due to the heat.

However, unlike the last heat wave, the air is expected to be less humid, at least initially. Therefore, despite the high temperature, it can feel a little uncomfortable.
