The Met Office issues a mix of amber and red warnings for extreme heat across parts of the UK as temperatures are forecast to rise sharply next week. Reports say a red warning for “extreme heat” is issued for some areas, with amber warnings also in place for a wider set of locations. Several outlets cite potential peak temperatures in the high 30s Celsius, including forecasts around 37C, 39C, and up to about 40C. The warnings come alongside assessments that there is a meaningful chance of temperatures exceeding record levels for the time of year, including references to the highest-ever June temperatures. Coverage also notes that the heatwave is expected to last several days, with red warning coverage extended to parts of the south coast in the middle of the week, while new amber warnings are issued for later days. One report adds that the UK’s marine conditions are experiencing a long-lasting marine heatwave, with risk of reaching rare “extreme” levels. Overall, the Met Office messaging focuses on the possibility of record-breaking heat, regional impacts across England and Wales, and changes to warning levels as the forecast evolves.
