Update at 8.20am, January 4: Delays of more than 40 minutes are being reported by BBC Sussex on the A26 southbound from Uckfield to Lewes due to roadworks.
And the BBC Travel website is reporting disruption at Barcombe where Barcombe Mills Road is blocked in both directions near the High Street junction because of flooding.
Our original story: A flood alert remains in place for the River Uck this morning after being posted by the environment agency at 3.56pm yesterday. An update is expected by noon today.
The level of the Uck peaked last night at about 10pm. At 4.30am today at Uckfield Mill it was recorded at 0.77m. The water is expected to rise again today as more heavy rain is forecast, writes Cathy Watson.
The highest level recorded Uckfield Mill is 1.49 metres, this was in February 2009. The typical range is between 0.30 metres and 1.30 metres.
The flood alert relates to the River Uck and the Framfield, Ridgewood and Tickerage Streams. It was issued after heaving rain over the New Year period caused the river to respond with the possibility of ditches and culverts becoming inundated adjacent to the river.
The Environment Agency is expected to update the flood status by midday today with warnings issued if the situation escalates.
The alert is the first stage in a system of codes. It means flooding is possible, be prepared. It is given two hours to two days in advance of flooding.
The advice is to be prepared to act on your flood plan, prepare a flood kit of essential items, monitor local water levels and the flood forecast.
There are two further stages, flood warning, where flooding is expected and immediate action required. This is given half an hour to one day in advance of flooding.
Then there is severe flood warning when there is severe flooding and danger to life. It is used when flooding poses a significant threat to life.
