People living in Sussex should not forget their umbrellas for the next couple of days as heavy rain is on the way.

The county is set to be battered by heavy showers with two yellow weather warnings issued for rain.

The first starts at 9pm today and lasts until 11.45pm on Thursday and the Met Office has now issued a second warning which includes the whole county and is in place from from 12am until 11.59pm on Friday. 

Forecasts show rain as heavy as 8mm per hour could hit Brighton tomorrow morning.

"Heavy rain may lead to some travel disruption and flooding in places across southern England and southern Wales during Friday," a spokesman for the national weather service said.

People living in the warning area are told to expect a slight chance of power cuts.

There is also a small chance that homes and businesses could be flooded, causing damage to some buildings.

"Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services," the spokesman added. 

"Spray and flooding could lead to difficult driving conditions and some road closures."

The Met Office has also warned of a small chance that some communities will become cut off by flooded roads and of fast flowing or deep floodwater causing danger to life.
