Europe heatwave live: UK issues rare red temperature warnings; French PM to hold crisis meeting after heat deaths

Britain is facing an unprecedented heatwave, with the Met Office issuing a rare red weather warning for extreme heat across large parts of England and Wales. Temperatures are forecast to soar, potentially reaching 38-40C (100-104F), marking a historic high for the UK.

It’s drawing warm air up from North Africa, from the Sahara, and that’s why we have this really intense heat.

The intense heat is attributed to an "Omega block" weather pattern, which is drawing scorching air from North Africa. Climate scientist Clair Barnes of Imperial College London explained that this pattern is "very slow moving," offering little respite from the heat due to a lack of wind. Experts warn that this extreme heat poses a "risk to life" not only for vulnerable populations but also for the healthy.

It’s very slow moving and it means there’s kind of no wind, ‌no breeze for respite.

The red alert, in effect from Wednesday to Thursday, signifies severe and significant impacts are expected. Beyond health risks, authorities anticipate substantial disruptions to transport systems, energy supplies, water, and businesses. The situation necessitates significant adjustments to working practices and daily routines. This marks the second red heat health warning issued in the UK, following a similar event in July 2022 when temperatures first exceeded 40C.

It is vitally important that people understand the risk posed by high temperatures like these, and take steps to keep themselves and their friends, families and neighbours safe.
