Overview
- The Met Office issued urgent thunderstorm warnings on Wednesday as a wet front moved south from Northern Ireland and Scotland bringing heavy, thundery showers across large parts of the UK.
- Forecasters say the rain will be very variable and not enough to end the drought overnight, with meteorologist Aidan McGivern warning showers will be ‘hit and miss’ and spatially patchy.
- Experts caution that baked ground cannot absorb intense downpours, so surface‑water and flash flooding are possible where storms produce 15–20 mm in an hour or up to 30–50 mm in six hours.
- Water and emergency services remain under pressure: more than 27 million people in England face hosepipe restrictions, Wessex Water has imposed a ban for 1.4 million customers, and this summer’s record wildfire toll has stretched fire crews and prompted military help.
- The weather shift offers short relief but not a long‑term fix, and Met Office long‑range guidance keeps open the chance of late‑season warm spells or a September heatwave that could prolong water and fire stresses.
