The UK Met Office is considering issuing a rare extreme heat warning after forecasting temperatures of around 36°C. Multiple outlets report that an update is being circulated ahead of a possible heatwave, with the aim of alerting the public if conditions meet the threshold for the most severe warning level.

The reports describe the “red heat warning” as an uncommon measure, suggesting it would be used only if forecasts strengthen. Coverage varies in emphasis: some focus on the rarity of such warnings and the potential need to formalise one, while others foreground the forecast temperature and the likelihood of further guidance being issued as the event approaches. All accounts point to the same core expectation—very hot weather and the potential for official escalation by the Met Office.

Overall, the story centers on whether the Met Office will move from advisory-level messaging to a “red” extreme heat warning, depending on how forecasts and conditions develop in the lead-up to the hottest period.
