I know we had heavy rain yesterday but I'm surprised by the flooding .Perhaps the rain was significantly heavier in Eg Camberwell and Battersea than we had in ED ? I'm wondering if drains were blocked ,possibly the recent dry spell meant a build up of debris that regular rain would flush down ,and if this was a factor . I feel sure ( often wrong when I feel like that ! ) we've had similar downpours in the past which haven't resulted in this degree of flooding . What do others think ? Oh ,and I understand about the heat meeting the cooler air and climate change .
