Heavy persistent rain which affected most parts of the country caused flooding in several areas yesterday with Met Éireann warning of further heavy showers and strong winds nationwide this evening.
Storm conditions coming in from the Atlantic will affect coastal areas in the south and west with the risk of flooding later today.
Met Éireann has also advised that the weather will remain changeable and unsettled for the remainder of the week.
Two male motorists were killed when their vehicles collided at Ballinahaglish, Co Mayo on the main Ballina-Foxford road at around 4.50am yesterday.
Both drivers, who were travelling alone in their cars, were pronounced dead at the scene of the crash by a local doctor.
The victims were named locally as Gearóid Scully, 47, a hackney driver from Childers Heights, Ballina and Terence Beagan, 37, with an address at Ravensdale, Dundalk, Co Louth.
The bodies of the men, who are understood to be married with families, were removed to the mortuary at Mayo General Hospital in Castlebar for autopsies.
Fire brigade crew who attended the collision had to use cutting equipment to free the victims from a Mercedes and Skoda Octavia.
Mr Scully, a native of Dublin who came to live and work in Ballina some years ago, was “well-known and well-liked”, according to Terry Nolan, a member of Ballina Town Council.
“The entire Ballina community is shocked and saddened by this awful tragedy which occurred only hours into the New Year,” said Mr Nolan “Our thoughts are with the families at this terrible time.”
The location of the crash around a mile outside Ballina on the N26 remained closed for most of the day as Garda forensic collision investigators carried out an examination of the scene.
Meanwhile, a man is in a serious but stable condition in hospital after sustaining a serious head injury in a road crash in Co Tipperary on New Year’s Eve.
The 22-year-old motorist, who is understood to come from Patrickswell, Co Limerick, is believed to have lost control of his vehicle before crashing into a ditch at Cappawhite at around 4pm on Tuesday.
He was taken by ambulance to University Hospital Limerick but was later transferred to Cork University Hospital for treatment for a serious head and spine injury.
Another male passenger in the vehicle was uninjured in the crash but was reported as suffering from shock.
Heavy rain, combined with strong gales, caused flooding in localised areas yesterday, with a number of diversions in place around the country.
