TRAVEL

Irish Rail DART services are only operating between Lansdowne Rd and Malahide/Howth due to flooding.

For full details of all diversion on Dublin Bus Routes due to poor weather conditions click here.

MAIN TRAFFIC

Flooding has been reported in the Santry, Swords and Malahide areas. 

A section of theBallymun Rd(R108) between Collins Ave and St. Pappin Rd is closed due to flooding. 

Flooding also to contend with onSantry Laneand as a result Dublin Bus are unable to serve the Santry Village or Beaumont areas.  

Achill Rd near Drumcondra is impassable.

In Dalkey, Gardai are advising motorists to avoid Barnhill Rd. 

On the M1 Belfast/ Dublin Rd, a crash has been cleared before J2 Dublin Airport but excess surface water has been reported along the route between J4 Lissenhall and J2 so take care. 

No delays to report on the M50 in either direction.

No major problems for the city centre traffic at this stage.

Not a comment on the current weather system, and maybe it should be in the "infrastructure" forum...but I see a swale under construction in Finglas(North Dublin) to accommodate flood events, in an area which has flooded and caused property damage twice in the last 6 years.

Meteoalarm has Ireland in the mix for a change -

"25-40mm of rain has accumulated in places up to 6.00am today, Saturday 2nd August. A further 40-60mm of rain is likely to fall in many areas up to 6.00am Sunday 3rd August."

Doesn't appear to be causing any problems yet.

I wouldn't be painting anything outside today.

We haven't had a drop if rain here in Dublin Northside in the last hour or so!

Absolutely bucketing rain on coast road east of Gorey, only started around 11 this morning.

Will the rain down south now push north this evening

Have to drive from South Dublin to Cavan in a few hours.. anything to worry about?

The areas that have dried out past 2-3 hours just to northwest of Dublin are close to the upper-level low which is drifting northeast and will be over county Down by about midnight, taking this drier zone along in that direction. At the same time, the occlusion running into the secondary surface centre under the upper low (the primary is over the north Irish Sea) will plod north and resume at least moderate rainfall for areas that it covers from Dublin north. On the east coast you can expect to see winds going from east to south, then southwest and west but inland the sequence will be from east to north and northwest then westerly.

The intense looking return flow from west across portions of Laois, Carlow, south Kildare will be dragged northwards and upslope against the Wicklow-Dublin Mountains could create locally heavier rains around the western portions of Dublin but then later this feature will be returning to the east coast without running into that upslope. There may be a slight rainshadow effect east of the hills that will fade out from Bray northwards later. So would expect a further 20-40 mm rain in most of Leinster as the dry centre of the system moves more into east Ulster. This wrap around could then become thundery with some hail embedded. Be alert for thunderstorm development about 4-7 p.m. in the Dublin region then this will slowly shift north during the evening.

The section of the storm now over west Ulster will be held in place for the rest of the day and through most of tonight, and I suspect it may be under-modelled so expect some locally torrential downpours in parts of Donegal, Sligo, Leitrim, Roscommon and eastern Mayo-Galway with 20-40 mm further rainfall there, also in Derry, Tyrone and Fermanagh.

This storm will likely continue for a significant portion of Sunday in most of Ulster and the parts of Leinster and Connacht within about forty miles of Ulster, and the current sharp boundaries may degrade as areas of showers begin to rotate around the more persistent rain bands.

Just about holding dry in Castlebar west is definitely best though as I can see croagh Patrick clearly and blue sky out towards clear island. As always MT spot on!!
