Further strong winds and widespread rain are forecast by Met Éireann for many areas of the country today - with the possibility of further flooding.
Drivers were last night urged by gardaí to be cautious, as severe frost was predicted for many areas last night.
A period of heavy snowfall early yesterday morning - up to two inches on higher ground - made driving difficult in the west, the south, and in the midlands as what forecasters called a "mini-depression" crossed the country.
A 34-year-old man died in a road accident near Ballinasloe, Co Galway, early yesterday morning. Gardaí say there was severe rain at the time.
The man, named as Mr Sean Tully, Moylough, Ballinasloe, died in a head-on collision between two cars on the Moylough to Tuam Road at 3 a.m.
Several sporting events were cancelled at the weekend. Punchestown racing was called off on Saturday and Sunday. All but one National Football League Division One GAA games were cancelled.
Winds of between 60 and 75 m.p.h. are forecast for this morn- ing, but conditions will generally not be as stormy as in recent days, said Met Éireann. Thundery showers were expected in the west.
Weather conditions began to deteriorate at about 7 a.m. yesterday, with snow and sleet falling over a large area stretching from Kerry to the Cavan-Fermanagh Border.
Difficult driving conditions were also experienced in Co Longford, Co Galway, Co Cavan, and parts of Co Roscommon, said AA Roadwatch.
The snow had stopped by lunchtime, but roads remained wet as snow turned to slush. Parts of Co Galway and Co Clare also experienced snowfalls and localised flooding.
Some roads in Dublin remained wet, but were suitable for driving, said AA Roadwatch. The ESB says power was returned to customers on Saturday night, but it is monitoring the situation, as high winds have been predicted.
A spokesman for Dublin City Council said the city's major emergency plan, invoked on Friday, has been scaled down. Efforts are now concentrated on cleaning up and providing advice for people affected by the flood.
Advice centres have been set up on Thorncastle Street, Ringsend, and at St Mary's Community College, East Wall.
The city council urged people, especially residents of Stella Gardens, Ringsend, to return to their homes, as the ESB had to reconnect power.
Roads around Killarney were dangerous and the Conor Pass between Tralee and Dingle was impassable early yesterday.
The weekend flooding in Baltray, Co Louth, was the worst experienced in over 70 years, according to local residents.
Ten elderly people were evacuated from their homes adjacent to the Boyne River at Baltray because of the rising waters.
They were all accommodated at the Baltray Golf Club.
Drogheda River Rescue, working at the request of the Irish Coastguard, and Drogheda Fire Brigade carried out the bulk of the evacuations using boats and a cruiser to ferry people away from the Boyne and Irish Sea as the flooding reached five feet in places.
The Boyne is tidal and although the high winds and spring tide experienced on Friday were not repeated over the weekend, all the emergency services were on standby.
The combination of wind and high tide swelled the river, resulting in flooding along the banks and of the Obelisk Bridge near the Battle of the Boyne site.
In Drogheda, the major emergency action plan was activated on Friday because of the extent of the flooding, which came within inches of topping the main bridge in the town.
Met Éireann's three-day forecast predicts a cool and breezy Monday night, with clear spells and showers.
Tuesday will be cold and windy with bright spells and showers, some with hail or thunder.
Wednesday will be another windy, showery day.
It will be a lot colder though, with many of the showers turning wintry.
