More than 1,000 tonnes of wood are ablaze in Tangmere.
Firefighters have been working throughout the night after a call was received at 8.59pm yesterday evening (August 1).
The fire is on agricultural land at Tangmere Airfield Nurseries, City Fields Way, and the wood was for scrap.
Firecrews are still currently attending the blaze.
They are ensuring that adjacent buildings are protected by using a mechanical digger and four hose reels to create a fire break.
The wood is being allowed to burn out, and the fire is currently estimated to have reduced by 40 per cent from its peak, but is still ongoing.
