    That's using 06Z GFS data. The 12Z run should show the strongest winds a bit further north. Will be rolling out shortly.

    They give out here about people getting carried away by changes on one run and not rely on it but Met Eireann seem to do the same in their extended forecast every morning. Surely a forecast like now i.e uncertainty and stay tuned would be much better forecasting.

    Also I just want to say that I believe Met Eireann do a great job overall and do not issue warning especially in more recent times unless warranted.


  • Registered Users, Registered Users 2 Posts: 11,134 ✭✭✭✭maquiladora


    12Z GEM has a HIRLAM-like track, a bit further north than the GFS.

    12Z ECM will be the big one though.

    DMI 12z showing pretty much the same narrow but potent swath of winds running up through the southern half of the country as Maq's chart in above post.
    Now let's hope for further upgrades in later runs

    I was referring to their written forecast on their website which I read first thing every morning together with MT's forecast!


  • Registered Users, Registered Users 2 Posts: 11,134 ✭✭✭✭maquiladora


    The HIRLAM track is not far off the Dec 1997 track. The white line shows where the strongest winds were in relation to the center, possibly in part due to a sting jet type feature. A difference between 1997 and this storm is that it in 97 the low was still deepening as it crossed the country whereas here it looks like it will peak close to or over the southwest.

    Still, even if there are no mesoscale features enhancing the winds, it could still be quite potent, and not just limited to coastal areas.

    That's all assuming the HIRLAM/ECM solution is the correct one. This is still 2 days away, things change!

    so much change already today that they will probably await for overnight runs or put out a yellow warning later this evening for Wednesday and upgrade accordingly (if necessary).

    GFS Ensembles have made a significant jog north with the track from the 6z.

    Hirlam type track now more preferred.

    A few 97' like systems

    big 48hr chart to come from the ECMWF tonight!

    It is interesting that ECM showed a storm potential for this week a few days ago, only to drop it over the last few days, then suddenly to bring it back. Must have picked up on something days ago. IF this low proves to be a vicous as forecast, then the ECMWF model has to be the winner regarding the pinning down of this particular feature.

    could this bring more flooding to cork city?:(


  • Registered Users Posts: 58 ✭✭snowstorm2013


    Holy moly, where did this potential storm come from. Evelyn said no more storms this week and suddenly met e are talking about structural damage. Although I think she was premature making such a sweeping statement.

    UK fax 12z appears to have track very slightly more south than hi res models on landfall, but pretty much the same tight gradient on S and SW flank.

    It looks like they left the fax unchanged from the 12Z UKMO global model.

    12Z ECM has 850mb winds >100 knots just off the southwest coast at 48 hours.

    It's almost identical to yesterday's 12Z run.


  • Registered Users, Registered Users 2 Posts: 11,134 ✭✭✭✭maquiladora


    EURO4 not in agreement with ECM/HIRLAM. A complex/messy looking center with the strongest winds further south.

  • Registered Users Posts: 2,981 ✭✭✭JanuarySnowstor


    Well a red alert going by tonights models.
    However time for it to downgrade so pbly wise for both Met Eireann and ourselves to see the morning runs first.
    Its all or nothing here for the South

    I don't think coastal flooding will be a concern with this. At least not as much as previous storms anyway.

    well that's one good thing.

    :-O I've missed a lot this afternoon it seems!!! Is it bad to be excited about this?! Would there be rain involved also if this comes off?

    Latest from MT:

    UPDATE _ Monday 10 February 2014 _ 7 p.m.
    ________________________________________

    ALERT for 3-5 cm of snow accumulating on some higher terrain above 150m above sea level on Tuesday, also more widespread hail or sleet showers, all of which will produce locally poor driving conditions but most notably in Connacht and Ulster, also higher parts of Kerry and west Limerick.

    ADVANCE ALERT for potential damaging south-southwest veering to westerly wind gusts to 140 km/hr in exposed parts of the south and east, possibly as far north as a Galway to east Ulster line, with models now showing an intensifying storm tracking northeast across Ireland on Wednesday afternoon. The details on this may continue to change, watch for updates.


  • Registered Users, Registered Users 2 Posts: 11,134 ✭✭✭✭maquiladora


    This is from the 0Z ECM, but 12Z seems to be pretty similar. Take it with a grain of salt as other models aren't showing something this severe. But this is what Evelyn was worried about on the forecast.

    These are 10m gusts in knots. This would be stronger than any previous storms this winter or probably any winter since 1997 for southern parts.

    gFZq0o2.png

    Meanwhile, the UK Met Office don't seem to be buying this track at all. Their own models suggest a more southerly track with the strongest winds heading for Wales/Southwest England. Even their "alternative track" is further south again.

  • Registered Users, Registered Users 2 Posts: 14,322 ✭✭✭✭leahyl


    This is all very tense stuff! Maq, at this stage is it likely that the South will get some fairly strong winds?


  • Registered Users, Registered Users 2 Posts: 2,343 ✭✭✭red_bairn


    Well if Clare gets hit badly, they might want to rethink about the report they sent to the government.


  • Registered Users, Registered Users 2 Posts: 4,939 ✭✭✭goat2


    i hope this does not come to pass this forecast that evelyn gave, MT is giving forecast for wind also, he is always spot on, wind storm after storm, must be loosening tiles with each storm, hopefully we will come out of it as we have the past storms,
    just started light rain at moment,

    what will friday morning early bring, i have a long journey to travel is there anything showing for that far on yet,

    Very complex situation with subtle differences within +50 and while the difference are subtle the impact difference on land is huge.

    Also anyone from Donegal needs to note that there is an Orange warning in affect for Donegal for next 24 hrs. I get why this thread is needed for this event but if this warning was for Dublin I think the thread would either include it or another thread with a Level 2 would be created.

    Yes. 12Z Euro4 at +48hrs has a belt of strong winds to the south of Ireland.

    Nothing certain about this storm yet. So much change in track already today but won't be tomorrow before any certainty. Interesting couple of days of weather though!


  • Registered Users, Registered Users 2 Posts: 4,939 ✭✭✭goat2


    it is brilliant to be able to look up weather ahead here, i am thankful for this
    .
    i have a query,
    i have one of those old weather clocks, i bought at car boot sale about 20 yrs ago and it is so accurate still, it hangs inside door in hall,
    but now that we have these deadly storms, i have noticed, that the needle has hit the bottom, but it is when the needle is rising i see the more severe wind,
    is it my clock or is this normal

    Usually the strongest winds occur just after pressure has hit the lowest and is starting to rise again, so yes it is normal.

    You can compare with many other websites around, such as the one in my sig.

    Fingers crossed for the UKMO solution.


  • Closed Accounts Posts: 3,548 ✭✭✭Harps


    Hard to believe that we don't even know what country this storm is going to hit yet and it's less than 48 hours away. A more southerly track has been the more frequent solution though the ECMWF and Hirlam are usually the most accurate models for this part of the world so it's anyone's guess at the moment, definitely going to be glued to the models tomorrow.


  • Registered Users Posts: 440 ✭✭je551e


    Strong wind and heavy rain in Kerry now
