Adverse weather and road conditions are today continuing to disrupt bus services, particularly in Limerick and Kerry.
These problems have lessened during the day however, according to Bus Éireann.
Most Limerick city services are now operating with the exception of 301 Shannon Banks, 306 O’Malley Park and 309 (St. Mary’s Park/Pineview).
The Killarney-Killorglin-Caherciveen and Waterville-Caherciveen services in Kerry are cancelled at the moment, although Dingle-Tralee is now back operating.
"Bus Éireann will continue to monitor this situation closely and we would advise customers travelling in the south west to contact their local travel office for information on individual services," said a company statement.
"Bus Éireann would like to apologise to customers for any inconvenience caused."
