Britain has been issued a power cut warning as the London and the south east is set to be hit by a barrage of torrential rain, gales, closed roads and flooding.

The Met Office warned temperatures will drop to 4C on Monday, but a wind chill in the air will leave it feeling as cold as -1C, and there is also the possibility of snow appearing in high areas.

Meteorologists are predicting gale-force winds and around two-and-a-half inches of rain starting Sunday night and could lead to major travel disruptions across the south and east of England.

Severe flooding and sudden power cuts could strike Monday, with a yellow weather warning in place from midnight through to Tuesday.

Several flood warnings and alerts have been issued Sunday, with heavy rain and strong winds expected in many southeastern areas of England, London and the South East on Monday.

The East Midlands, East Anglia and Yorkshire and Humber are also expected to be affected.

Flooding and spray on roads is likely to lead to hazardous driving conditions and even some road closures, as well as delays or cancellations to train and bus services, the Met Office say.

Homes and businesses also could be flooded, causing damage to buildings, along with power cuts and transport services hit.
