    What I was referring to was the change in wind speed with increasing height above the surface, i.e. if you had several anemometers at different heights at the same station then what difference would we see between each one. Over land the difference would be much less than over sea as turbulent eddies would be much more dominant over land and would ruin any laminar flow gradient present. The figures I posted apply to sea stations, such as buoys, ships, platforms, etc. That is why I always treat wind ship reports with caution until I check out the height of the anemometers, or indeed if one was used in the first place (some ship wind reports are human estimations).

    Very heavy rain in Cork over the last hour, after a few hours of moderated rain before that.
    The rain is going nowhere fast either judging by the radar.

    Wicklow lots of water on n11 and secondary rds

    Isn't Heligoland with 1,7 km² like an offshore platform with three weather stations at 4, 8 and 53 m, all in a distance of half a mile and less?

    Where is everyone??
    Snowing here in Cork where I am (roughly same height as Cork Airport)
    Its wet snow but still

    Are you sure its not sleety rain? :P

    Looked like it was possible on high ground around there on the NAE alright.

    I would imagine most of us are sulking after the latest ECM output.

    Raining steadily here since about 3pm. A lot of surface water on the roads around here. I took a drive up the mountains to about 400m asl an hour ago to try and get a fix but not a flake to be seen, rain all the way. Might be a few white summits by morning though.


  • Closed Accounts Posts: 4,791 ✭✭✭JJJJNR


    Was just out for a quick spin to the shops and there is a bit of sleety rain about at the min, but its a bit milder now at 5c than at any stage today.

    Sleet now being reported at Cork AP at 2100 at 2c DP 2c.

    257 flood warnings in the UK now. As wet as it's been here, we're lucky we escaped the worst of it.


  • Closed Accounts Posts: 2,774 ✭✭✭Big Daddy Cool


    ive been watching this systems movement alot today, i taught it was moving east/northeast and would just about miss us here in north meath but now it seems to be moving back towards us, can somebody explain why this is, really need it to stay away.


  • Registered Users, Registered Users 2 Posts: 3,065 ✭✭✭JanuarySnowstor


    Heavy Sleet / Wet snow now in Cork not far at all from the real thing.
    Jean Byrne didn't even mention the word sleet on latest forecast.
    She did say it may turn milder next weekend
    I say try get tonight right first Jean!!!!

    2100 ORK metar confirming sleet. What's up with the TAFs around the country. The are the poorest I have seen yet! Not even a mention of precipitation. Shambles from SNN met.


  • Registered Users, Registered Users 2 Posts: 5,068 ✭✭✭Iancar29


    The weather will do what the weather will do :)


    Here the latest radar shot though showing rain turning to sleet in places :)

    has been raining very heavily all day here (arklow) but really lashing now and blowing a stink too. there was a lot of surface water around the town earlier so i would imagine there is some flooding now


  • Moderators, Home & Garden Moderators, Science, Health & Environment Moderators Posts: 18,283 Mod ✭✭✭✭DOCARCH


    Light rain now being reported for Cork AP at 2130 at 3c DP 3c......that's winter come and gone now for Cork I'm afraid! :p

    Rain total here now stands at 24.6mm since 3pm.


  • Closed Accounts Posts: 5,550 ✭✭✭Min


    Rain getting heavier here, 2.9C, DP of 1.1C and the trend is downward.

    11mm so far here.

    Shambles? ORK is right on the edge of the precip band. MAybe a PROB40 RA should have been issued, but what other TAFs are wrong "around the country"?

    Now anyone could have looked at the radar today and seen that dub was going to get RA for most of day/evening:/night just by looking at its movement. That does not take a scientific brain. Maybe the regionals are the same. Havnt looked at there tafs ( not that interested in them ) would you like to be sitting in your A320 in a nice MUC and have a nice surprise on approach to DUB with a break u/s, so yeah a shambles and dangerous lack of interest from snn met.

    Yes, Dublin's was out on the precipitation alright, although only light to moderate rain, vis always > 10km, so it wouldn't be a significant problem. Ceilings turned out near or slightly better than forecast though.

    The regionals have all been fairly spot on. Waterford has been behaving as forecast


  • Closed Accounts Posts: 15,515 ✭✭✭✭admiralofthefleet


    power is just back after an hour long cut. weather is atrocious here in arklow

    Dublin Air has had considerable rain today i sincerely doubt the visibility has been above 10km.


  • Registered Users, Registered Users 2 Posts: 1,789 ✭✭✭BEASTERLY


    Wexford town experiencing widespread flooding. My facebook is 'flooded' with pictures and post about it. A sample of statements from local media:
    Severe Flooding in Wexford town. Distillery Road closed, King Street closed, Davitt Road closed. Severe Flooding in Bing, Rosslare also. Wall after collapsing at bottom of Summerhill due to huge pressure of water, ESB enroute to kill the power in a transformer there also- so it looks like there will be powercuts shortly too.
    Emergency services stretched to their limit.
    The latest from AA Roadwatch.... WEXFORD... A number of roads in Wexford Town are impassable due to flooding; Kings St, Davitt Rd, South Main St, Upper John St, Old Ferrycarraig Rd and also the local roads between Wilkinstown Cross/Glynn, Murntown/Kildavin, Ardcolm/Castlebridge and Taghmon/Adamstown.

    Just back from work, there's flooding around Dublin too in spots. The autumn leaves blocking the drains no doubt playing a large part. Must be some pretty large rainfall totals in the Wicklow mountains with these NE winds.

    Have a weather station?, why not join the Ireland Weather Network - http://irelandweather.eu/

    Its been raining here almost constantly in Waterford all day/night. Rain still lashing against the windows here. Absolutely miserable!


  • Registered Users, Registered Users 2 Posts: 6,700 ✭✭✭Mountainsandh


    Yeah we're back to lashing rain up a bit higher here (co Waterford) too. All the snow has turned to mushy sleet, hoping it'll all be well thawed and not frozen in the morning.


  • Registered Users, Registered Users 2 Posts: 1,789 ✭✭✭BEASTERLY


    N25 flooded at Kilrane, near to Rosslare Europort.

    Looks like the models were spot on yesterday with the high amount of rainfall for Wexford.
    You could be right Maq but did they get it wrong for Dublin,it hasn't stopped since early afternoon here,miserable day.
    What were the rainfall predictions for the big smoke?

    Looks like the models were spot on yesterday with the high amount of rainfall for Wexford.

    The rainfall radars have not agreed though, I've been watching it all day and Wexford was mostly zero to light rain all day according to that. The surrounding counties have seen heavy rainfall all day so maybe it's all spilling out through Wexford hence the flooding?

    Edit: for example, the UKMO radar goes back to 1800 and you can see the pattern which has been the same since the rain arrived.... ie. Wexford in the clear.

    Was out on the precipitation! Yes it certainly was, to the point of non existent. Funny it was on the 1100 taf but not the 1700 and hey look at the 2300!! And no light RA around here fot the last number of hours. Maybe question the Metars too! 9999, emmmhh, I don't think so. So dear met eireann, do explain?

    Still a little light rain here. Total of 43.6mm here since 3pm yesterday.


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    24 hour total 56mm plus 11mm the previous 24 hours

    The 56mm needs to be verified with manual gauge, but even if above 50mm it is my wettest day since I commenced 09-09h (standard met day) rainfall obs in May 2001.
