Some places could see significant amounts of rain falling in a short period of time, bringing the potential for localised flooding, travel disruption and frequent lightning.“On Thursday, slow-moving heavy and thundery rain may bring prolonged rainfall to some areas, increasing the risk of localised impacts. There remains some uncertainty around where the heaviest rain will fall, so it is important to keep up to date with the latest forecast and warnings."The incoming downpour comes as England and Wales are expected to record one of the driest summers on record. Almost three-quarters of England is designated as under drought, as is the entirety of Wales.Scientists previously warned that a heavy downpour could cause more harm than good following the dry and hot summer, as it could lead to flash flooding in parts of the country.Areas under the Met Office warnings
