Heavy Rain Risk Sunday Night/Monday

Yep...never seen rain in Ireland before like the last ten/fifteen minutes here in Cork City (southside). Unreal. And it is still coming.

You'd miss Owen. No doubt Coleraine had 200mm of rainfall today!:pac:

You can catch him over in AH giving out about young girls gone to the bad smoking and cursing.

The funny thing is that his location prob saw very little today, he always misses the storms and is far to close to the coast to get any real low temps in winter or high ones in summer, yet he makes those outrages claims!

Yeah MT ,

It is much better when people have their locations though I understand if they dont coz they may not live there. e.g I live in Sligo, hail from Mayo and work in Roscommon

Rain broke my primary gauge with the points.

Luckily the secondary one got working but only an estimate really and rain for Sligo so far is 36mm since midnight. Really impressive rainfall for the whole country today. This is the wettest day for all Ireland Id say since I set up my website in July 2008. Not a long time I know but sure was wet.

Lovin all the graphs and stats by you all..

Flippin heck

Over 85mm of rain in Knock so far from midnight to 11pm. One Hour left and its still raining there. That must be a record for that station

Really?

We shall see tomorrow when the media get their mits on the stats.;)(though theyll go here to get em)

Usually the heaviest rainfalls are found about half-way up slopes facing the oncoming moisture-laden clouds in any given climatic zone. I'm sure this would generally be true in Ireland but when you have convection of course the maximum will be wherever the convective clouds travel, if they happen to go upslope they will dump more of their load there too. Depends on how big a barrier the hills or mountains form, here on the west coast of Canada they form a very large barrier to the point of taking all the rain from some systems, and there are places about halfway to summit levels on the coast here that get 3-5 times as much rain as we get in the flat plain that the city is built on. In Ireland the mountains are not that high so I would imagine you might find 30-50 per cent increases in regional rainfall long-term at some locations that face south, east or west (north rarely being a direction for moisture-laden air to arrive). Perhaps someone knows of a station that illustrates this, but I'm sure it would be the case. Then there are of course rainshadow effects in given wind directions, because the extra rain that falls on the mountains is no longer available to fall downstream in the air flow. I gather that Dublin and Casement were in somewhat of a rainshadow for most of this past event, getting less rain than Ballyhaise or other places not being shielded from the SSE by the Dublin-Wicklow mountains.

Where I live, we get a rainshadow from the Olympic Mountains in northwest Washington state, but this is much more of a factor in Victoria, BC where they only get half the annual rain that most of the Vancouver area gets. It can rain heavily there too but the wind has to come in from either the southeast or the west to avoid the big rainshadow effect.

I think it was captured about 24h ago now ... if you look at the met.ie radar feature now and animate it, you can see the swirl of the upper level low right about over Mullingar, with moderate rain bands wrapping around that now from the northwest. This feature will only drift a bit further east before daylight returns, then the whole air mass to the south which is fairly quiet at this point will become unstable with the daytime heating. But some rather heavy rain could develop overnight around the upper low in central and northwest counties.
