Apologies for my ignorance, but does that mean, that at that point in time, the extreme east coast is escaping the worst ?0 -

I can't see this happening....
According to http://www.narccap.ucar.edu/data/data-tables.html "1 kg of water forms a cube 1000 cubic cm in volume. Distributed evenly over 1 square meter, this forms a layer 1 mm in depth."
So roughly converting that from water to snow kg/m^2 works out about the same as cm.0 -

Kerry will have 52KG of Snow per M2 ( more than the Alpine ski areas ) and Wickila only 33KG 0 -

52kg: 52l of water: 52 mm of precip.
Based on water content of snowflakes, 1 mm ppt in snow form can be anything between 6 to 20 mm of snow.
You do the math from here

I said anyhing up to 10ft
For that, you need a place where snow be "blown into", and get stuck, and you need a constant strong wind from the same direction for at least a day or snow, with snow that is dry enough to drift.
In my country (Hungary) it's quite common, we have "genovan" mediterranean cyclones that usually have a mild frontal zone, that ofter turn to rain and give very high ppt amounts, and strong, windy "backside" fronts that give slightly less ppt but they are very cold and windy, and can even cause a 3-4 inch snowfall to build massive drifts up to 2m or more (in areas which are not protected against drifting snow).
The real deal comes when the cold in the basin is so strong, that even the frontalzone of the medi-cyclone cannot turn to rain - in sever cases 40-60 cm's of snow can fall in 36-48 hours. In my town, 2003 February saw 55cm of snow from 1 storm, but in Feb 1999 the NE part of the country has seen over 80 cm's 0 -

Wow Wow Wow Wow Wow I mean we gotta love every bit of snow we get don't we...0 -

Important details like precip type, amounts and locations are nowhere close to being nailed yet so while that snowfall accumulation chart makes a great desktop background, the next output could and probably will show a lot less snow.
For example, the 0Z : http://www2.wetter3.de/Animation_00_UTC_05Grad/174_24.gif
Still know, tis rare indeed to see stuff like that.
Yeah, I was deliberately giving an extreme example. In 2003 we had snow drifts of up to 4-5m in some roads, wheres the total precip was only about 20-25mm. The key factor was the blizzard-like wind for 2 days during, and after the storm.
And I agree, we certainly cannot take this event's extreme snow amounts for granted, but just even to see these amounts for Ireland on this chart is absolutely blinding 0 -
