Storm Ali : Weds 19 Sept 2018

    The main models have been showing a very vigorous system for Weds for a number of runs now. This storm is being aided by a very fast jet. It's track could drift further North as they sometimes do and it could have lesser wind speeds by Weds but at present it is worth keeping a record of it's progress I think. We can change the title if needs be.

    Borderline at the moment. 12Z ECM calling for mean >80km/h and gusts >130km/h, both red criteria, over small portions of Galway and Mayo.

    Probably not quite enough for them to go red yet on balance - they don't pull that trigger when it's so marginal (which of course defeats the purpose of the criteria, but hey, that's another debate).

    Any upgrades between now and Tuesday however and it will be red for parts of the west.

    Going by the lack of action on here and M.Ts tame forecast for Wednesday a Red seems like a long shot.


  • Registered Users Posts: 10,666 ✭✭✭✭MJohnston


    If the ARPEGE pans out there would definitely be Red warnings in the west:

    U2Wijw8.png

    This wind would be preceeded by a fair amount of rain too, so with the trees still holding onto all their leaves, and the worst of it being around midday, I'd definitely call this a Red if it pans out.

    latest form Met Eireann.

    Very disturbed weather expected through the rest of the week.

    Wednesday: Wet and very windy on Wednesday especially during the morning, with widespread rain and some very heavy falls expected through western and northern counties especially, with local flooding. Very windy countrywide with strong to gale force southerly winds, possibly reaching storm force at Sea off the west and north coasts. Winds will veer westerly in the afternoon and later moderate. Highs of 14 to 17 degrees Celsius. Some further heavy rain possible Wednesday night in southern areas especially near the south, drier elsewhere with scattered showers.

    Cross model agreement on very windy weather countrywide on Weds. More so in the W and NW , some models showing the SW very windy for a time early morning.

    Going to stick a yellow advisory on the thread title. Can upgrade later , quite possiby orange warning for quite a few areas.

    Worth noting some models showing some windy weather on Atlantic coastal counties Tues evening / Night.

  • Moderators, Science, Health & Environment Moderators Posts: 12,069 Mod ✭✭✭✭Meteorite58


    Weds charts make today look like a gentle breeze. Difference in timing and each with a slight difference in strength but looking very windy for most and extremely windy on Atlantic coasts especially in the W and NW and possibly SW.

    Helenes downgrade would make me a little bit hesitant giving my opinion ( and it is only that ) but the charts have been holding the wind speeds for Weds. and looking like widespread gusting to 85-90 km/h with higher winds possible maybe gusting 110 to 120 overland also. ARPEGE showing parts of the NW getting gusts 120 to 130 km/h atm.

    Overall the tendency with wind prediction charts is to ease nearer the time. Over the last few days there has been little change from what I can see.

    Will see the ECM later. One of the more reliable charts.

    WRF -NMM just rolled out and cintinuing the theme for widespread gusts 90-100 km/h and possibly higher in places.

    Needless to say a concern with all the trees in full foliage. Saving grace that it is moving through fairly quickly but looks like all places getting 4 -5 hrs or there abouts of very strong winds.

    Looks like the South/South West/West could be in for some orange alerts + in the coming days from Ali. Wonder if Met Eireann will mention it soon, it is only two days away.


  • Registered Users, Registered Users 2 Posts: 9,234 ✭✭✭sdanseo


    Consistent red warning criteria met again now on guidance from the last 2-3 runs on multiple models.

    If we don't see red for western coastal counties, I will understand why, but it will also make an absolute mockery of the existing warning levels.


  • Registered Users, Registered Users 2 Posts: 8,219 ✭✭✭Gaoth Laidir


    ECM 12Z out now

    Mean speeds

    Those mean speeds are for 100 metres agl, not 10 metres.


  • Registered Users, Registered Users 2 Posts: 9,234 ✭✭✭sdanseo


    Those mean speeds are for 100 metres agl, not 10 metres.

    Yup, any orange/red warnings based on ECM will be for gusts not mean. Mean barely about 65km/h for the most part but gusts >150km/h.


  • Moderators, Science, Health & Environment Moderators Posts: 12,069 Mod ✭✭✭✭Meteorite58

    ECM showing a potential 'sting jet' developing near north coast?

    Mean speeds in excess of 50 knots in just a very small area. Way too early for this to be anyway accurate though.

    Admittedly on second look, the first scenario looks a little anomalous. Very small area and very high in comparison to the surrounding contours.

    In fairness, you didn't specify which level the winds should be in the post I replied to ;)


  • Registered Users, Registered Users 2 Posts: 8,219 ✭✭✭Gaoth Laidir


    The ARPEGE has highest mean winds of 75 knots and max gusts of 99 knots north of Malin Head Wednesday afternoon. Prone to overdoing it in windstorms but with the ECM pointing in that general direction it will be interesting to watch reports from Donegal Airport, Malin Head and the Hebrides. Definite stingjet signals.

    The name Helene has been thrown around a fair bit over the last few days, so it's just easier to go with that.

    Anything else thrown in the mix, unless significant, is more confusing for the majority reader.

    Let's make a pact on here not to quote or be in any way concerned about how 'newspapers' are reporting on this potential. Media companies have no interest in raw facts and are not motivated by concern for society at large nor are they following any moral compass. They are driven solely by profit and they can publish horse **** like this on daily basis (not just on weather, but on many topics) because they are largely unaccountable.

    but you see the ploughing is on this week so they ain't gonna call a weather warning untill last minute in case it dissipates and they end up getting sued for loss of earnings or some such


  • Registered Users Posts: 10,666 ✭✭✭✭MJohnston


    One thing we never really got a good read on last year was whether Met Eireann had any rules around separation of individual storm naming - as in, do they just merge the effects of one into the other if they're less than 24 hours apart.


  • Registered Users, Registered Users 2 Posts: 9,234 ✭✭✭sdanseo
