Heavy rain across the country caused traffic chaos for this morning’s commuters.
Met Eireann issued a gale warning and have predicted rainfall of up to 30mm today.
In Dublin, traffic was very heavy on the M50 southbound.
There was a crash at the Blanchardstown Junction 6 exit and one lane was blocked at the Lucan Junction 7 exit, AA Roadwatch reports.
In Cork, surface water and heavy rain resulted in two collisions on the South Ring Road westbound before the Kinsale Road roundabout.
The two collisions were cleared quickly.
Traffic was also heavy from the Mahon direction towards the Jack Lynch tunnel.
In Tipperary, there was a crash on the M7 southbound after Junction 22 at Roscrea.
Galway and Limerick were both very busy on the roads as heavy rain created extra traffic.
Rain will be heaviest up until midday with the possibility of some localised flooding.
"The weather is set to improve today" a Met Eireann spokesperson told the Irish Independent.
"It will brighten up this afternoon. It’s not the start of anything bad, just a very wet morning."
"Tomorrow is set to be fine again, but it won’t be as nice as it was yesterday or the day before," he added.
"There will be more rain on Friday morning but it will be a reasonable amount of rainfall."
Motorists are being advised to drive with care as surface water is present on the M8 Cork/Dublin Road around the Fermoy exits, on the N72/Tallow Road out of Fermoy.
It is also reported in the Ballinasloe and Loughrea areas of Galway and on the Clones/Cavan Road in Monaghan.
Amd those who skipped the roads were at no advantage as Irish Rail's new policy meant DART trains ran with four carriages each again this morning.
Fine Gael TD Simon Harris has described the second disruption in three days to rush hour commuters as unacceptable.
He called on Irish Rail to review how it deals with a crisis and to put a halt to its new policy of using four carriage trains during rush hour.
“For the second time in just three days, commuters woke up to disruption on the DART line this morning with trains running up to 20 minutes late, leaving passengers waiting in the pouring rain,” the Wicklow TD said.
Later this morning, the showers will clear in the southwest and should be cleared nationwide by this evening.
The sun should make an appearance later in the day with high temperatures of 12 to 16 degrees and windy conditions.
