High winds and rain are set to lash the county this weekend.
The Met Office has given a yellow warning for rain tomorrow (November 24) and Sunday.
Forecasters are expecting as much as 100mm of rain in 24 hours while the shoreline will be battered by winds of up to 60mph.
A spokesman for the Met Office said: “There is potential for another spell of persistent and heavy rain to spread from the south to affect the southern half of the UK over the weekend.
“This will also be accompanied by strong to gale force winds which could exacerbate any possible disruption.
“The public should be aware of the potential for further localised flooding and disruption to transport.”
The average rainfall for England in November is about 90mm.
Preparations Southern Rail were preparing for the worst after other rail services were hit with flooding and fallen trees as the storm gradually moved south.
A spokesman for Southern Rail said: “We’re preparing for the wet and windy conditions that are likely to prevail tonight and tomorrow morning.
"All our station staff are busy battening down the hatches and ensuring that everything that isn’t bolted down is safely stored away. We know from previous bad weather incidents that preparation is vital and all Southern managers and staff are ready to tackle everything from flooding to trees on the line.”
The Environment Agency said recent downpours had led to the ground being saturated which could lead to surface water flooding if the rain falls as heavily as predicted.
But as of yesterday it had not put in place any flood warnings, which relate to river levels and not surface water flooding.
It follows wild weather earlier in the week which saw trees felled and surface water flooding on Wednesday, November 21.
East Sussex County Council reported fallen trees on Wednesday at Church Lane, Hellingly; Holteye Road, Hammerwood; New Road, Glynde; Cowbeech Road, Rushlake Green; Bodiam Road, Bodiam; Legsheath Lane, Forest Row; Downs Road, Hastings and Forewood Lane, Crowhurst.
Elsewhere in the country saw major flooding with vehicles abandoned and reports of entire villages being cut off as floodwater surged through lanes and streets and into homes.
In some cases, more than two inches of rain fell in one night.
