The United Kingdom is preparing for a significant weather event this week, with the Met Office issuing warnings for widespread thunderstorms across England and Wales. This comes as forecasters predict temperatures could soar, potentially making it the hottest May day on record.
Temperatures are expected to reach as high as 28C in some areas, particularly parts of south-east England. If this prediction holds true, it would surpass the current May record of 27.8C, set in both 2012 and 1999. The warmth is attributed to a plume of hot air moving northwards from the continent.
However, the heat is also bringing instability, leading to yellow thunderstorm warnings. These warnings cover a broad swathe of England, from the South West up through the Midlands and into parts of the North West and North East. Wales is also included in the advisory, with the potential for heavy downpours, lightning, hail, and strong winds.
The Met Office has cautioned that these storms could lead to localised flooding, particularly in urban areas, and disruption to travel. Power cuts are also a possibility due to lightning strikes. Rainfall totals could be significant in short periods, with some areas potentially seeing 20-30mm of rain in an hour, and even up to 50mm over a few hours.
While England and Wales bear the brunt of the warnings, Scotland and Northern Ireland are expected to experience a somewhat more settled, though still warm, picture. Temperatures there are also forecast to be above average for the time of year, but without the same widespread risk of severe thunderstorms. Wind speeds during the storms could reach gusts of 30-40 mph.
Members of the public are advised to take precautions, including staying indoors during severe weather, avoiding unnecessary travel, and being aware of potential hazards such as flash flooding and slippery roads. It is also recommended to secure any loose outdoor items to prevent them from becoming projectiles in strong winds.
