The ITV Meridian region is enduring the worst series of winter storms in more than 20 years, weather experts have said, as the country prepares for even more flooding.
Coastal areas - particularly in southern England - are most at risk as they cope with a combination of unusually high tides and another Atlantic storm today. The PM was questioned about cuts at the Environment Agency on ITV Meridian earlier this week.
When questioned about the Environment Agency's ability to fund flood defences on the BBC's Andrew Marr Show, Mr Cameron replied: " We're spending £2.3 billion in this four-year period on flood defences which is more than the previous four-year period.
"We have also enabled them to access other sources of money - partnership funding - so I think we're going to see record levels of spending on flood defences and we have guaranteed that right out into 2020 so they can really plan for the future.
Mr Cameron went on: "Huge sympathy to anyone who has had their house flooded. Anyone who has had a house or an office flooded knows it is absolutely dreadful.
"I think the community response has been incredible. I saw for myself how people come together and help and the emergency services have done an absolutely great job.
Video. High winds and rain continue to batter the region, with flood warnings remaining in place in parts of the South. At Iford Bridge Home Park in Dorset, around 100 residents were evacuated from their homes, next to the River Stour.
They have now been told they won't be able to return home, until next week at the earliest.
Juliette Fletcher spoke to resident Martin Sadler, Councillor Lawrence Williams from Bournemouth Borough Council and Chris Bainger from the Environment Agency.
The Met Office has issued another severe weather warning for tomorrow after the region has just recovered from the turbulent conditions earlier this week.
They predict that gale-force winds up to 70mph will hit southern England and will disrupt transport across the region.
Heavy rain is expected in the morning, with further wind and rain arriving on Tuesday.
The Environment Agency have published a list of counties who are at risk of flooding, with Kent and Medway the only counties at medium risk across the UK today.
According to the list, tomorrow and Sunday only holds a low risk of flooding for counties around the UK.
Today there are low risks for: Brighton and Hove, East Sussex, Hampshire, Isle of Wight, West Sussex, Dorset and Wiltshire.
Tomorrow the only counties in our region at low risk of flooding are: Kent, Medway, Dorset and Wiltshire.
Dorset and Wiltshire also remain on the list for risk of flooding on Sunday.
Parts of Kent could be hit by the worst floods seen in the county for 60 years overnight. That's the warning tonight from the Environment Agency.
The most severe warning possible - danger to life - has been issued for Sandwich near Deal. Gravesend, Medway and Seasalter are also at high risk of serious flooding. In all, between 1,500 and 2,000 coastal and riverside homes are said to be in danger.
A number of factors are combining to cause concern. High winds are coinciding with high spring tides causing a prolonged surge down the east coast and into the Channel.
The high risk times are just before 1 o'cock in the morning - the area most at risk is The Quay at Sandwich, where the Environment Agency says flood defences are likely to be breached. Sarah Saunders reports.
There is more information about the flood warnings on the Environment Agency website.
The Environment Agency released this video which details the process involved in the £28m flood protection scheme in West Sussex.
Medmerry's 'managed realignment' scheme is part of an ongoing project to improve sea defences and will improve flood protection for more than 300 homes.
The Environment Agency is launching a new project to protect Salmon stocks in the Solent.
The Salmon Watch campaign is part of the Environment Agency's ongoing crackdown against fish theft and illegal angling.
Rivers in Hampshire are world famous for their salmon populations but surveys on the River Test and Itchen show that numbers are well below their conservation target.
Since a previous anti-poaching campaign in 2012, Environment Agency Fisheries Officers have arrested or cautioned five poachers who were caught fishing illegally as a direct result of reports received from the public.
The sunshine in parts of the region is good news - not just for sailors - but for those enjoying a day out on the beach or in the country. But it's also brought a note of caution from the Environment Agency
It's warning of the dangers of jumping into rivers to cool off and comes a year after a teenager died when he leapt from Donnington Bridge in Oxford. Officials say there could be unseen hazards.
Thames Water has been fined more than £27,000 for causing the pollution of a river in Surrey
