UK heat warning extended to four days as 38C forecast

An amber weather warning for extreme heat has been extended across the UK, with the Met Office predicting temperatures could soar to 38C (100F) in some English regions next week.

The updated warning is now active from Monday morning through Thursday night. This extension reflects growing confidence in forecasts of exceptionally hot and humid conditions expected to persist mid-week. The warning covers significant portions of England and Wales, with some northern areas included on Wednesday and Thursday.

Forecasters anticipate widespread daytime temperatures exceeding 30C (86F), with the potential for localized highs around 38C. Overnight temperatures are also expected to remain unusually warm, particularly in urban areas, where they may not drop below 20-21C, leading to "tropical nights."

The extreme heat is spreading from continental Europe, where an intense heatwave has already developed. Parts of western France could experience temperatures between 43-44C (109-111F) in the coming days, while Paris might reach an unprecedented 40C (104F) for June.

The Met Office warns that these conditions are likely to lead to population-wide impacts. These include serious health risks for vulnerable individuals, disruption to daily routines, and increased pressure on essential infrastructure like transport and energy services.
