Road users around Waterford are being urged to take extra precautions today as a number of routes are affected by snow and ice.
The M9 was closed for a time this morning northbound between Mullinavat and Knocktopher following a two car collision.
The cars have been now removed and the road reopened at around 9am, but gardai say there are huge tailbacks heading onto the M9 as a result.
There are also reports of black ice approaching Five Crosses and Ballyvooney Hill in Stradbally, the Pike outside Dungarvan and the Ballyduff upper Road is reportedly dangerous.
A large amount of debris on the N25 Waterford/Cork Rd just before Youghal Bridge was cleared this morning.
Many pavements around the county are very slippy.
