'Localised' flooding has occurred overnight in Portarlington after parts of the river flowing from Mountmellick to Portarlington reached its highest ever recorded level yesterday.
Director of Services at Laois County Council, Kieran Kehoe, has said that localised flooding has occurred overnight in the town.
"Botley Lane, the Bog Road and Patrick Street have experienced localised flooding. We have been in discussion with Offaly County Council since last night. We are setting up diversions along these routes.
"There is a stop/go system on Patrick street at the moment and it is likely that this road could be closed off later today," he said.
AA Roadwatch have already reported that Patrick Street is closed and all motorists should avoid the town.
The Portarlington Rd (R423) is closed between Mountmellick and Portarlington due to flooding.
Traffic delays have been reported in the area.
Laois Civil Defence and Irish Defence Forces were deployed to Portarlington this morning to help people that have been hit by flooding.
