West Sussex is set to be hit with heavy showers and strong winds ahead of Christmas Day.

The Met Office has issued a yellow weather warning for the county, along with all of London, southern England and south Wales.

The 'be aware' alert runs from 6am on Wednesday until 6am on Thursday - Christmas Eve.

Forecasters are warning that most areas could see between 20-40 millimetres of rain in that time - potentially rising as high as 70 millimetres in the worst hit areas.

What can we expect?

  • There is a small chance that homes and businesses could be flooded, causing damage to some buildings
  • There is a small chance of fast flowing or deep floodwater causing hazardous conditions
  • Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • There is a small chance that some communities become cut off by flooded roads

What are the Met Office saying?

"Spells of heavy rain are expected across southern England and parts of south Wales during Wednesday and into early Thursday.

"The heaviest rain is likely to develop during Wednesday evening and continue overnight before clearing away to the southeast by Thursday morning.

"Much of the area is likely to see 20-40 mm through this period.

"There is still some uncertainty in exactly where the heaviest rain will fall but there is the potential for some places to see as much as 50-70 mm of rain.

"The heavy rain will be accompanied by strong north to northeasterly winds during Wednesday evening and overnight."
