Yellow Weather Warning Issued Across UK Amid Heavy Showers and Thunderstorms

Strategic Insights -

A 15-hour yellow weather warning has been issued across the UK, with multiple rounds of 'heavy showers and thunderstorms' forecast by the Met Office. Despite swelteringly high temperatures across London this week, the Met Office's yellow weather warning remains in place, covering all of London and most of the UK down from around Newcastle-upon-Tyne. The warning is expected to remain in place until midnight.

Heavy showers and thunderstorms are expected to develop through Thursday afternoon and evening across parts of central, southern, and eastern England, and perhaps also south Wales. These have the potential to produce 50 mm or more in 1-2 hours, along with gusty winds, large hail, and the risk of surface water flooding. A yellow weather warning also means there is a chance of flooding.
