Core Event – Met Office Issues Yellow Thunderstorm Warning Across Large Parts of the UK
The UK Met Office has placed a yellow weather warning for thunderstorms over extensive areas of England, Wales and the Midlands. The warning began at midday on Friday and runs until 9 p.m., covering 18 Welsh counties and a swath of English regions from the North East to the South West. It follows earlier alerts responding to a wet, storm-laden bank-holiday weekend.
Background & Context
The warning arrives after an unusually hot and dry summer that left soils hard and susceptible to rapid runoff. The Met Office has warned that lingering heat and recent drought increase the likelihood that heavy rain will generate flash flooding. Earlier in the week the Environment Agency issued one flood warning and 39 flood alerts across England.
Data & Statistics
- Expected rainfall: 10–20 mm in a short period, with 30–40 mm possible where downpours repeat; up to 50 mm in 12 hours and isolated peaks of 75 mm.
- Wind gusts: 35–45 mph in southern England and Wales.
- Additional hazards: hail, frequent lightning, and short-term power outages.
- Observation: Met Office spokesman Stephen Dixon reported 52.8 mm recorded in Lichfield between 5 a.m. and 9 a.m.
Official Statements & Responses
The Met Office advises motorists that “there is a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times.” It also warns of possible train delays, power losses and limited flooding of homes and businesses. Safety guidance includes seeking shelter in an enclosed vehicle or building if thunder is heard, avoiding tall objects, and moving to lower ground on elevated terrain. Residents in flood-prone areas are urged to prepare a flood plan and an emergency kit.
The Environment Agency’s alerts reinforce the warning, indicating that flooding is possible in numerous locations and urging the public to stay informed of local updates.
