Storm Benjamin is causing travel chaos across the county this morning.
The A20 Ashford Road at Hothfield, Ashford, is currently closed following a three-vehicle accident likely to have been caused by the poor driving conditions.
The road is said to be flooded from the aptly named Watery Lane to the Sandyhurst Lane junction at Potters Corner. The emergency services have been contacted for further information.
On the Isle of Sheppey, both Halfway Road in Sheerness and Lower Road in Minster have been reported as flooded.
In other travel news, there is queueing traffic on the coastbound carriageway of the A2 near Gravesend, following an earlier lorry fire.
The incident happened near the Hever Court Road junction for Henhurst and the Cobham Services. Congestion is trailing back to Pepper Hill.
The A249 southbound is also partially blocked, with traffic queueing for three miles due to an accident after the A2 Key Street Roundabout. Journeys are said to be taking 25 minutes longer than usual.
There is also heavy congestion on the QE2 Bridge at Dartford for traffic coming from Essex in the clockwise direction on the M25, with queues snaking back to the J30 Lakeside turn-off.
Crossing the Channel, Irish Ferries has announced delays of up to 90 minutes on its services between Dover and Calais due to poor weather conditions.
A flood alert and two weather warnings for rain and wind are in place for Kent today.
The Met Office has put out yellow alerts for the whole of the county, and also for London and Essex.
Heavy rain is expected to continue all day until 9pm this evening, with up to 50mm falling in some places, while strong winds, gusting up to 65mph are also expected all day.
The bad weather is being caused by "a complex area of low pressure over the mid-Atlantic.
The weather watchdog says motorist should be prepared to encounter flooding on roads and difficulties with visibility because of spray.
A Met Office spokesman said: "In association with the rain, conditions are expected to be windy with a chance of gales, initially along southern and eastern coasts, but more widely across southern Britain during the day."
The watchdog suggests residents should ensure movable objects such as bins and garden furniture are secured and warned that there could be a chance of power outages.
The office suggested the pubic should ensure they keep torches, batteries and mobile phone power packs to hand, saying: "It is better to be prepared."
Residents near the coast are advised not to stand on the beach or harbour wall to admire the waves as there is a risk of being swept in.
Similarly, avoid walking close to the edge of cliff tops.
Meanwhile, the Environment Agency has issued an alert warning of flooding today in Hythe, Dymchurch, St Mary's Bay, Littlestone, Greatstone, New Romney and communities on the Romney Marsh up to the Royal Military Canal.
