The Met Office issued an amber weather warning over the city and surrounding area. Power cuts have already struck Hayling Island, with National Highways and rail companies issuing warnings about disruptions on the roads and the trains.

The forecaster said "dangerous" conditions are to be expected due to ferocious winds and intense showers - potentially being a "danger to life". They added: ""Storm Isha will bring a spell of very strong winds during Sunday evening and into Monday. Disruption to travel and utilities is likely. Very strong west or southwesterly winds will develop widely during Sunday evening, persisting overnight and into Monday morning.
