    Storm Ciara was not felt at all really, Just seemed like a normal week of weather with a bit of wind, everyone seems to be loosing their minds when anything with wind gets named

    Looks like it wasn't felt where you are but it was felt elsewhere.

    Meteorologists's Commentary . Storm Dennis – Saturday 15th to Monday 17th 

    Storm Dennis is forecast to track to the north of Ireland and the UK over the weekend. It will likely bring periods of very wet and windy weather, with some stormy conditions possible, particularly later Sunday into Monday.

     

    The Meteorological Situation:

    Cold air is forecast to exit Canada and enter the North Atlantic Ocean over the next few days, creating a sharp temperature gradient in the atmosphere. This will result in an intensification of the jet stream, which will direct low pressure systems towards Ireland.

    Gales are likely in coastal areas on Saturday with fresh to strong winds inland. Winds could increase further on Sunday, possibly becoming stormy, particularly along western coasts. It will be very gusty too over the weekend, with some damaging gusts possible.

     

    Flooding issues

    We are entering into a period of transition between Spring (High) Tides and Neap (Low) Tides. This means there will not be a large variation between high and low tides. The combination of high seas and strong winds or perhaps stormy conditions, may increase the possibility of coastal flooding especially along western and southern coasts due to wave transformation.

    Storm Dennis may also bring very wet conditions with localised flooding possible. River levels are elevated across much of the midlands so any heavy rainfall would cause issues here.

     

    Storm Naming

    Storm Dennis is the fourth named storm of the season. The naming convention now also includes the Dutch meteorological service, KNMI as well as our existing partner UKMO. Storms are named to aid the communication of approaching severe weather, helping the public to be better placed to keep themselves, their property and businesses safe.

    Keep up to date

    As forecast confidence improves over the coming days Met Éireann will issue warnings as required. Please check for updates

    Not related to Dennis but that's one humdinger of a low coming off New Foundland today. 987 hPa at 12Z today, 943 hPa by 12Z tomorrow, a drop of 43 hPa in 24 hours.

    300 hPa jet stream Friday night. Another night for record-breaking translatlantic flight times...

    ECM looking the strongest for winds on Sunday at this stage . Currently strongest winds in coastal counties and strongest along the coasts.

    It's a complex beast . The system seems to be more like a number of areas of LP being absorbed to form one large storm . The whole mass does a pirouette in the Atlantic near Iceland before swinging in towards the North of Scotland on Sunday. Showing getting down to an incredibly deep 921 hPa on Sat and charts showing 950 hPa when it is off the NW on Sunday evening. Looks to produce a few wave depressions on it's journey so a lot of uncertainty as to what comes in close to us or not. It is probably better viewed as a collection of deep areas of LP maybe ?
    Gerry Murphy mentioning Sunday keeping an eye on as could be stormy. Much rainfall in the lead up to this also and looking very wet over the weekend, areas quite saturated and standing weather in fields so some flooding in places probably an issue over the weekend and into Monday. His comments would tally with the ECM charts, GFS whilst strong not showing stormy yet.

    Saturday quite windy and wet in it's own right, very windy along coasts and quite windy blustery during the frontal passage over the country.

    Sunday looks to be very cold day with sleety wintry showers possible.

    Latest ECM for Sunday. Seems to be the hint of a secondary feature tightening up the isobars a bit over Ireland.

    That actually is Dennis, its forecast to spin around in the north Atlantic for the next two days (forecast to get down to 925hPa!) before weakening as it moves over us on Sunday

    The latest 48hr OPC chart (below) has it at 916 hPa with another low of 928 hPa chasing it. Some beast, and there's a strong possibility that the two lows will merge. A 'perfect storm' ? ...

    Wev had very high tides in Sligo the past 3 days with overtopping

    However Spring tides abating this weekend but Dennis will bring enormous swell to Salthill Strandhill and Lahinch for example

    ECM very windy across the country during the frontal passage on Saturday, and signs that the S and SE could be very windy again Sat evening for a time.

    Sunday looking very windy along Atlantic coastal counties and blustery across the country and very windy across Northern counties later. Bit of a spread in timing and strength of winds in the models yet.

    Very wet day Sat into Sun. Heavy showers and cold on Sunday into Monday with some more prolonged spells, some showers wintry.

    Very big seas out in the Atlantic the next few days.

    All this hype with named storms has caused the connacht schools cross country races scheduled for Saturday in Loughrea to be cancelled. If you ask me it is very early to be calling this.

    Expect plenty more events to be called off by the end of the weekend. Better safe than sorry.

    Looks like some very complex and messy evolution over the next 48 hours with multiple centres each with very low central pressure, should make for some interesting satellite pics!

    So what happens if they go ahead and a kid gets hit on the head by a falling branch or something flying around the place would you take the responsibility in this day and age of claims they are correct.

    This month so far must rank as one of the lowest average pressures over the Atlantic basin. I'd like to see the anomaly up to now.

    Language, there Timothy, sorry, eh... Tomer.
    Words like 'bomb' should be avoided these days esp.if you want to be taken seriously. It is however shaping up to be a threatening scenario, especially for shipping. Watching the models - we'll know more in another 24-36 hrs. Interesting will be how the lows will interact and where exactly Dennis will march after peaking.

    The event was scheduled for tomorrow, Saturday. They have all day today to make a decision. Again the warnings and further forecasts are due today so we will wait and see what conditions will actually be like. What if...

    There is Dennis at 6 am this morning, 984 hPa southeast of New Foundland. By midday tomorrow it will be 924 hPa south of Iceland, with a messy and potent frontal system crossing Ireland. A filthy day in store tomorrow.
