This is a normal occurrence in rough weather. The island can usually be cut off for days.

Indeed in 1974 they were cut off from the mainland for nearly two months.

Probably the pick of the 0Z run. Gut feeling tells me i jumped on the Roller Coaster too soon.

Still a real lack of certainty on the models as to where the low will develop, some runs have it deepening as it crosses us, other don't have it develop until its well out in the north sea

Holland and Belgium will be at real danger from a North Sea storm surge on this mornings GFS again

I bet it will do what most interesting looking lows do. Travel further north.

Donegal's busiest road was flooded last night at an area called 'The Dry Arch'.

Although todayfm described it as the Dry Arch Roundabout between Stranorlar and Derry. For those who dont know its in Letterkenny.

But there IS a Dry Arch Roundabout, isn't there? Unless I've been seeing things on my way north.... But maybe that's not where the flooding was.

On a slight aside, maybe you weather boffins can enlighten me - when did the new weather stations appear on the Sea Area Forecast? Sherkin Island Auto? Mace Point? Never heard of 'em. I'm normally an obsessive listener to the SAF, but haven't heard it in a while. Have they done away with some other weather stations?

Seen no snow ether on the weather for the weekend!

Things are actually looking much better from todays run , The colder air will stick to us for longer and there will be snow next week if the charts turn out to be true.

No snow for the south east though I bet

Looking at the latest models I would say that later Sunday and through Monday we will see snow down to around 100 m in the northeast to around 350 m in the southwest.

It's looking like a northwest -southeast gradient throughout the country, leading to strong west to northwesterlies at all levels. 500-1000 thickness ranges from around 524 dam in the northeast to 532 dam in the southwest, with partial thicknesses (850-1000) in the 1290-1300 range. I would be looking for 522 dam and 1280 dam, respectively, for snow to all levels.

850 hPa theta-w of around 2 °C in all but the south, and 850 theta-e of around 13-14 °C, along with good boundary layer mixing, would suggest that any showers that feed in from the northwest will be mostly snow above around 100 m for northern Connaught, Ulster and north Leinster, rising to around 350 m further southwest, but there could be some lowering of these levels in the squalliest of the showers.

North east? F*ck. Last thing I need next week is snow... I know it's impossible to tell but is this a temporary event or something that could get prolonged?

Gobbledygook translation? If I told you an airliner crashed because of an ELAC 1+2 fault combined with ADIRU misalignment, and dropping out of Normal law and a sustained alpha above 30 degrees would you know what I meant?

Yes I would, but I would hope that you would first summarise it in plain English for those unfamiliar with the terminology, like I did! The details were added for those interested in why I thought what I thought in the first paragraph - for all others, skip through to the next chapter please!

Absolute comedy gold!... If centipede's had hands there wouldn't be enough for THAT faceplant

Whatever about snow, potential for some of the showers to be thundery under such a set up, especially in more coastal regions.



Hopefully we will see some nice troughing develop within the flow closer the time.
