Gardai are warning of dangerous driving conditions this morning due to snow and ice in many parts of the region.
Gardai say conditions in the Ballina, Claremorris and Castlerea areas are especially slippery, while side roads in those areas are very dangerous.
There has been a fresh fall of snow in Castlebar this morning too.
There is frost in places around Bangor this morning also.
Gardai are dealing with a collision on the Tuam Rd southbound between Milltown and Tuam at Castletown. Take care along this route; conditions are slippery due to snow.
There are also icy conditions around Roscommon Town.
