There are reports of a widespread diesel spill on the main Armagh to Portadown Road.
A large section of the main carriageway, between Armagh and Portadown, has been affected.
One local motorist contacted Armagh I and asked us to warn others to slow down and exercise care and caution.
She said: “It’s from the Mall right up Victoria Street towards Portadown. It only seems to be clear at the roundabout entering Portadown.”
The driving conditions are made worse due to the rain and with more forecast overnight people should drive appropriate to the conditions.
