Elsewhere large sheets of timber have been reported on the M8 in the overtaking lane between Rathcormac and the Toll Bridge, an ESB pole is down in Dungourney at Ballyspillane Cross Roads, another tree is down at Kennys Cross on the Fermoy to Castlelyons Road and on the Mogeely Road in Castlemartyr
