The Environment Agency has issued 305 flood warnings across England and 50 people were evacuated from Hackney Wick in London last night after a canal burst its banks. South Western Railway services have been disrupted across the network, with significant problems occurring on lines in the West of England. The operator said: “Whilst we expect water levels to drop and most of the network to reopen today, South Western Railway will not be able to operate services between Yeovil Junction and Exeter because of a landslip near Crewkerne. “Disruption to the rest of the network is expected to last throughout today due to displaced trains and crews.” A London party boat which is a floating bar, restaurant and nightclub has sunk in the River Thames amid heavy rainfall. Elsewhere, a major incident was declared yesterday in Nottinghamshire as residents have been evacuated amid flash flooding from Storm Henk. A spokesperson for Nottinghamshire Fire and Rescue Service said the water levels will continue to rise over the next 12 hours.
