3 articles · Updated · BBC.com · Jun 21
Summary
The amber extreme-heat warning now runs from 01:00 BST Monday to 23:59 Thursday, with the Met Office saying confidence has grown that hot, humid conditions will persist through midweek.
38C is possible in the hottest parts of England, while temperatures above 30C are expected widely across England and Wales and some cities may stay above 20-21C overnight in tropical nights.
Large parts of England and Wales are covered, with more northern areas joining on Wednesday and Thursday as the warning expands to places including Manchester, north Wales and farther west toward Plymouth.
Population-wide impacts are likely, including health risks beyond vulnerable groups, disrupted work and daily routines, and extra strain on transport, energy and water-safety services; the UK Health Security Agency has also issued heat-health alerts.
The heat is spreading from continental Europe, where western France could hit 43-44C and Paris may reach an unprecedented-for-June 40C, underscoring scientists' warnings that climate change is intensifying UK heatwaves.
