More heavy is now expected to hit Dorset later this evening, the Met Office has confirmed.
The Met Office has issued a new yellow weather warning for rain up to 40mm of rain expected to hit much of the county overnight.
The warning will be in place from 10pm on Tuesday, November, 26 and will be in place until 12pm on Wednesday, November 26.
It is likely to lead to further disruption to people travellinga nd could see more flooding across the county.
The Met Office has said that flooding to homes and businesses is 'likely' and that it will have an impact on bus and train services.
A spokesperson for the Met Office said: "An area of rain is expected to reach parts of southern England overnight Tuesday, becoming persistent and heavy in places for a time.
"Much of the warning area will see 15-20 mm of rain with 30-40 mm in some areas. There is a lower chance of 50 mm of rain in a few places, more likely for the Isle of Wight, Sussex and Kent, before rain eases and clears by early afternoon. Given recent wet weather, some disruption to travel and infrastructure is likely.
It comes after Storm Bert battered the county over the weekend leading to many roads being flooded across the region.
Fallen trees from strong winds also blocked the train tracks resulting in cancellations.
