Heavy downpours and thunderstorms have caused severe flash flooding in parts of London in the end of the weekend, last week. The Environment Agency issued two flood warnings for areas in London near Beverley Brook in Worcester Park and West Barnes. The storms were being caused by a “convergence” of air currents as warmth in the earth’s surface from the recent heatwave rose into cooler air in the atmosphere. Many roads in the capital were closed because of the flooding, including the Blackwall Tunnel, the A12 and parts of the North Circular. In Hampshire, the roofs of two semi-detached properties were severely damaged when they were struck by lightning. Officials have advised against traveling in the hazardous conditions. The streets turned into rivers. London buses, cars and taxies were seen crawling along waterlogged roads. Drivers were stranded for more than three hours on parts of the A3 near south west London on Sunday night.
Torrents of water gushed into Pudding Mill Lane tube station at Stratford. Chaos was caused at hospitals. Hundreds patients were evacuated and ambulances diverted. Barts Health, London’s largest health trust, declared a major incident after water flooded the basement at Whipps Cross Hospital, causing damage to the electrical system. Whipps Cross Hospital in east London has also cancelled all planned surgery. Newham Hospital was also affected. London Fire Brigade says it has taken more than 1,000 calls with crews rescuing stranded motorists and residents trapped in flooded basements. It’s the second time in a month that the capital’s streets have been underwater. The Met Office has issued further warnings over rain and thunderstorms in England and Scotland over the next four days.
