About 60 homes have been flooded in Hampshire and the Isle of Wight after heavy rainfall.
About 40 homes in Emsworth were flooded, with half having to be evacuated.
Residents were moved from their homes in inflatable boats, with reports of 5ft (1.5m) of floodwater in some homes, and cars submerged.
Another 10 homes were flooded on the Isle of Wight, roads were closed and two schools were shut.
Bridge Road and St James Road were the worst-affected areas in Emsworth.
One woman had to be rescued from her home in a boat along with her one-week-old baby, who was taken to a waiting ambulance for a check-up.
Emsworth Community Centre was opened for householders forced from their homes by the floodwater.
Car roof level
About 40 people were evacuated from the properties but another 38 people chose to stay despite the flooding, Dave Smith, station manager from Cosham fire station said.
He said many of the homes were under "quite a lot of water".
"The sort of water levels we're talking about is up to car roof level," he said.
"Fortunately we've got no bungalows affected, they're all two-storey premises. If there were bungalows they would be the first priority to be evacuated.
"For those who are [staying] in affected properties, it's a case of reassuring them that everything is being done possible to ensure their welfare and safety.
"In conjunction with the police water rescue unit we are going out and checking back gardens and sheds to make sure all the pets are OK."
Fire and rescue crews from across the county were drafted in to help.
Several other flooding incidents were reported in Denmead and Hayling Island in Hampshire.
Meanwhile, in Ryde on the Isle of Wight, Monktonmead Brook burst its banks.
