The Met Office has issued a yellow storm warning for most of the UK on Tuesday as the conditions could also cause transport disruption and power cuts in areas hit by heavy rain. Hail, frequent lightning and flooding are possible as the rain is likely to become more concentrated in southern parts of England later. Rain is expected across Scotland on Tuesday but will gradually clear as the day goes on, with Northern Ireland the driest. Tuesday’s forecast follows heavy rain and flooding in parts of Devon and Cornwall on Monday afternoon, while storms developed in east coast counties including Essex, Suffolk and Lincolnshire. The rainy weather comes after weeks of little rain and high temperatures that have caused droughts in several parts of the country as well as fires and blocked pipelines. Videos shared on social media showed a roundabout near a river in Truro, Cornwall, quickly flooding as showers rolled in. Despite the expected storms, the Met Office said Monday was the eighth consecutive day of 30C recorded in the UK. Met Office forecaster Greg Dewhurst said temperatures would be cooler on Tuesday, with a high of around 27C as a maximum. Flood warnings as water drains from surface Image: Localized flooding in Tullow, Co Carlow in Ireland on Monday As a result of the dry ground in recent weeks, experts have warned that the potential for flooding is greater as surfaces act “a bit like concrete” and water drains rather than seeps. “There’s damage to homes and businesses that these floods can cause and inconvenience with disruption to transport, but if it’s very heavy in one place it can also be very dangerous,” said Professor Hannah Cloke, a hydrology expert at the University of Reading . London Mayor Sadiq Khan warned people in the capital on Monday to prepare for flash flooding this week amid heavy rain and storms.

Experts warned that city drainage systems may not be able to cope with a sudden downpour, as water will likely run off land that has dried up after weeks of little rain and hot weather. Geographers and meteorologists say that the best type of rain to bring the earth out of its dry state would be a light drizzle. Possible travel interruptions Use Chrome browser for more accessible video player 0:32 Heavy rain and flooding hit Cornwall Mr Dewhurst warned that bad weather could cause difficulties for those hoping to travel and urged people to keep up to date with developments in their area. He said we would see some “very heavy rain develop over the next few days”. Yellow weather warnings are also in place for southern England on Wednesday, where communities could be cut off by flooded roads and the possibility of fast flowing or deep flooding could pose a risk to life. But as the week progresses, the weather is forecast to become windier with some rain particularly in the north of the UK. Mr Dewhurt said temperatures would generally be around average for many, but could potentially be a bit warmer for the far south, in the mid-20s. “It looks probably very likely late Wednesday into Thursday and then it gets fresher for everybody,” he added.
