    hurricane forecast for north scotland tonight, does this mean ireland will get a kicking to??

    There is no hurricane, it is a hurricane-force winter storm, and is what brought the strong winds to Ireland today. It is moving off towards northern Norway so will not be an issue for us anymore.

    Some impressive winds were reported by land stations in this storm, which is currently located off the coast of northwestern Norway. Remember, these are on land - winds at sea could have been higher!

    Akraberg (Faroe Islands, 99 m) 75 gust 105 knots
    Klaksvik Heliport (Faroe Islands, 84 m) 61 gust 93 knots
    Torshavn (Faroe Islands, 54 m) 58 gust 89 knots
    Krakenes Lighthouse (Norway, 41 m) 58 gust 78 knots

    Define "later". Match on in the sportsgrounds tomorrow at 6:30pm , could make it interesting.

    Probably a bit late to be posting but I was on the ferry from holyhead last night and it put me off ferries for life. The storm had.the boat all over the place an people getting sick everywhere. 3 metre waves apparently but felt like 30! I wish is read this thread beforehand. Longest three hours if my life

    Some of the higher res models seem to be picking up on the potential for a polar low like (I say 'polar low like' as I am no expert on these elusive little feckers! :D) feature to develop off the west coast of Norway somewhere between 65-70 deg N sometime tomorrow.

    Forecast MSLP & Prep chart for 1800 UTC tomorrow:

    Models have this system developing within the remnants of a slack trough (or vacuum!) that is forecast to be left behind by the storm system that is currently affecting much of the northern half of Norway at the moment.

    EMHI HIRLAM MSLP & Windspeed forecast chart for 1800 UTC tomorrow:

    Some pretty potent winds tightly packed close to the actual core of the low.

    Though I don't have the knowledge or confidence to call this a full on Polar Low the feature does look like it could be entirely convective based due to the fact that sub -8.0c 850 hPa temps are moving in over much warmer SST's, I.E, instability.

    Could be an interesting one to watch (maybe)

    Yes, I was looking at that yesterday and 850 hPa theta-w values show a non-frontal warm core system, with gale to storm force winds circulating around the tight centre. The 500 hPa temperatures are not quite the sub -40 °C usually required, but the as you say, the warm SSTs offset that somewhat, so we could be looking at the first polar low of the season.

    Incidentally, here's a photo of Kråkenes Lighthouse on the Norwegian coast during yesterday's storm. Winds reached 58, gust 78 knots.

    ...and here it is on a slightly more normal day! PS. The lighthouse is now a B&B, so imagine waking up to that yesterday!
