As a brief but intense heat settles over southern Britain, the UK Health Security Agency has issued yellow alerts warning of elevated risk to vulnerable lives through the weekend.

Rain is expected to follow, yet forecasters and hydrologists alike caution that a few millimetres of weekend showers cannot undo what weeks of absent rainfall have quietly taken away.
