West Sussex sees 30 days of rainfall
According to the Met Office, the UK has already seen 89% of the average rainfall expected for the whole of winter.
West Sussex has recorded more than thirty consecutive days of rain.
That's according to the Met Office, which says England's already exceeded the average rainfall expected for this time of year by 11 per cent.
Almost 100 areas have been warned to expect flooding as downpours continue, with no sign of a prolonged dry spell for at least a week.
The Environment Agency (EA) warned flooding was expected in 99 areas, mostly across the south of England, around the southern Welsh border and in the East Midlands - and was possible in a further 170 areas.
At least 300 properties have been flooded so far, the EA estimates.
Andrew Hitchings, flood duty manager at the EA, said: "With another band of rain on its way, we need the public to remain vigilant to the risk of flooding.
"As well as significant groundwater remaining likely in parts of Dorset and Wiltshire, there are risks of significant river flooding impacts on the Somerset Levels, with minor river flooding impacts expected in parts of the East Midlands and probable in Worcestershire and Gloucestershire.
"So far more 16,000 homes and business have been protected but sadly 300 have suffered flooding and our thoughts are with those communities affected.
"Our teams will continue to do all they can to support local people, with pumps, temporary barriers and by clearing waterways to ensure flood water can drain away."
