Flood warnings?

With all the snow that has fallen on high ground, and so much melted on a daily basis at ground level, are there any flood warnings on any rivers at the mo? Certainly fields are saturated etc...

Local authorities don't give river warnings like they do in the UK....

We have a much better drainage system in Ireland and less concrete jungles, so warnings are rarely required, afterall, 1mm of rain = 1cm of snow, so if there has been 10mm country wide this week in more prone parts, it still should not be a problem.

In frost/thaw/frost scenarios, soils become slow at releasing water to the sub soil levels, hence the bad fields setup.

Well, I'm mindful of what happened in Dunboyne, Blanchardstown and Drumcondra 2 years ago with the persistant rain and the Tolka, and with all the melt and it being fed into drains...

I think you will find that actual rainfall amounts are nothing unusual for this time of year, and in areas were snow is going to suddenly start melting..thats most likely going to be higher areas and thus areas more used to higher runoffs, probably Dappergent can correct and clarify here, I don't think it will be a problem though.

Yes, very true Longfield, but there have been loads of bad planning over the last decade or so, building on flood plains etc. Rivers like the Liffey who start up high in mountains would be ok, but something like the Tolka is likely to occur sooner rather than later. I must have a look-in there tomorrow.
