Bring it on?

I'll let someone better qualified to do the technical thread.

Looks like lasting about 4 days as its progress bogs down south of Iceland - around 945 mb at the peak.

Casement gusting 98km/h in 1000 reports, which is pretty strong for that location.

Doctors room ghost

Sheets of constant heavy rain in east Galway and a strong wind driving it.every place already water logged.floods and water closhes everywhere.
She’s down for the day too by the look of it.
I’m mighty sick of this weather

Very regular run of the mill weather for winter. Warm front with rain had cleared. Cloudy, mild and and breezy at the moment. Later on the cold front will cross, it might bring a squall line in the process and if so rain will become heavy/very heavy for a few minutes and there'll be some standard run of the mill and to be expected gusts to go with it, as is normally the case. Then the cold front will clear, temperatures will drop and there'll be some showers and it'll feel cold in a strong breeze. As is always the case during these run on the mill "events", winds will be strongest in the usual standard places, high ground and near coasts where winds will be onshore.

Oh, did I mention that the weather today is regular, to be expected run of the mill weather?

uchimata83

Starting to flood already around north kerry, rain is constant but with sporadic extremely heavy downpours. Certainly not run of the mill stuff, high tide tonight should be fun

So that’s two storms in a row who decided to make a weekend of it.

Snow Garden

Very wet in Galway. Not too windy yet.

CirrusBusiness

Some very damaging gusts just passed through here. Big limb has come down off the ash tree down the garden and lost a fence panel.

Are winds to be as strong tomorrow? (Orange?) We weren't expecting this level of wind from Dennis.

The cold front is currently encroaching on on the west and there's a squall like feature developing from Galway down to Kerry so weather is probably quite poor in the West and South west right now. The worst of this winter low week have passed you on a few hours. Spring tides have passed so flooding should not be a major issue, perhaps some right by the coast however minor coastal flooding is a semi regular thing and is expected at least a few times in any given winter.

So far, only one synoptic station is reporting wind gusts over 100k/hr. Sherkin Island is the only station reporting mean speeds of gale force 8. No other stations are reporting gale force. Sherkin is also located within the area that is expected to receive the highest wind speeds and it is as exposed as can be.
