1900hurricane Posted December 24, 2013 Share Posted December 24, 2013 Down to 927 mb with 06Z UKMET analysis. Should be peaking right about now, conveniently just as it becomes illuminated.

Chinook Posted December 24, 2013 Share Posted December 24, 2013 927mb as per UK Met office official analysis. That's the lowest pressure I've seen from a non-hurricane 39 ft waves that this buoy http://www.ndbc.noaa.gov/station_page.php?station=62081 933mb at this buoy http://www.ndbc.noaa.gov/station_page.php?station=64045 Link to comment Share on other sites More sharing options...
Lorenzo Posted December 24, 2013 Share Posted December 24, 2013 Looks like another one inbound for Friday. This system named 'Dirk' by the Free University of Berlin is still currently rattling away to the North of Scotland at 933mb. From the satrep report a lively looking picture across UK and Europe with the extent of this system reaching Africa. Merry Xmas ! Link to comment Share on other sites More sharing options...
Roger Smith Posted December 25, 2013 Share Posted December 25, 2013 A more intense windstorm is expected to hit Ireland and the UK on Thursday night -- not as low a central pressure (945 mbs) but stronger gradients. This is the storm that recently hit the eastern U.S. and southern Ontario over the weekend, having redeveloped off NS and now south of St John's NL.

1900hurricane Posted December 25, 2013 Share Posted December 25, 2013 Yeah, the next one looks more like a classic bomb versus the past one which seemed to get going in very low background pressures (although it would be quite a mistake to say that the past one didn't bomb or wasn't significant). It's already getting its start SE of Newfoundland, per 12Z analyses. Link to comment Share on other sites More sharing options...
1900hurricane Posted December 25, 2013 Share Posted December 25, 2013 Speaking of the past storm: @bbcweather Stornoway reported a barometric pressure of 936.4mb at 1230pm today. Lowest recorded anywhere in the UK since December 1886. Peter G Link to comment Share on other sites More sharing options...
Chinook Posted December 26, 2013 Share Posted December 26, 2013 Next installment-- I believe this Atlantic low will bomb into the 940's soon Link to comment Share on other sites More sharing options...
Matthew-Northern Italy Posted December 26, 2013 Share Posted December 26, 2013 Lot of snow in the mountains here in northern Italy in the past 2 days, with locally more than 4 feet. Snowlevel is still too high for the season (generally above 2500-3500 ft), but in the coming days it should decrease and for january 2th, we should have the first shot for serious snow in lowland. Meanwhile, some pictures of today from italian Alps ... Link to comment Share on other sites More sharing options...

1900hurricane Posted December 27, 2013 Share Posted December 27, 2013 Beast low. I don't believe I have ever seen the North Atlantic as active as it has been so far this winter, and particularly in the past week or two. Link to comment Share on other sites More sharing options...
Matthew-Northern Italy Posted December 27, 2013 Share Posted December 27, 2013 So..... it snowed 4 ft on Christmas Day? Yes, 4 ft in about 30-35 hours. Locally have fallen till 300-400 mm of precipitation in 2 days, especially in lake Como area, southern Switzerland and western Friuli (Aviano area).

The_Global_Warmer Posted December 27, 2013 Share Posted December 27, 2013 I can't even read what pressure this fantasy bomb goes to on the Euro. But it looks like the gradient is quite strong. Link to comment Share on other sites More sharing options...

That's about 940 mb or so counting isobars. Deep for sure, but it almost seems run of the mill due to how intense these storms have been lately.

Chinook Posted December 31, 2013 Share Posted December 31, 2013 The latest GFS has another 936mb storm in the middle of the Atlantic, east of Newfoundland, in a few days (4-5 days). This develops directly out of the low in the United States. The WW3 wave model predicts waves over 50ft near there. Link to comment Share on other sites More sharing options...
1900hurricane Posted January 1, 2014 Share Posted January 1, 2014 The OPC is being rather aggressive with the depth of the low. Link to comment Share on other sites More sharing options...
jordanwx Posted January 1, 2014 Share Posted January 1, 2014 67ft open ocean SWH predicted by WW3...insane. It is rare to see WW3 go over 55ft. It was modeling ~50ft SWH for the two ~935mb and ~945mb storms which bombed in the N Atl last month. This storm could produce some of the tallest satellite confirmed open-ocean wave heights from an extratropical storm. All thanks to 75kt surface winds Link to comment Share on other sites More sharing options...
1900hurricane Posted January 4, 2014 Share Posted January 4, 2014 Winds are well in excess of Hurricane force on the south side of the most recent bomb. Link to comment Share on other sites More sharing options...
jordanwx Posted January 4, 2014 Share Posted January 4, 2014 Storm is peaking in terms of winds. Peak winds of 77kts at 10m per GFS. 102mb pressure gradient on the backside of the storm. Insane. Link to comment Share on other sites More sharing options...

Diego Posted January 4, 2014 Share Posted January 4, 2014 934 mb low east of St. Johns, Nfld and south of Greenland at 12Z. And sustained winds of 95kts or 105mph at the Hibernia obs. ist. Link to comment Share on other sites More sharing options...
bluewave Posted January 4, 2014 Author Share Posted January 4, 2014 Very impressive stats for the UK in this strong +AO/+NAO pattern. http://metofficenews.wordpress.com/ Since the start of December the UK has seen a prolonged period of particularly unsettled weather, with a series of storms tracking in off the Atlantic bringing strong winds and heavy rain. The windiest month since 1993 In order to compare the recent spell with the numerous stormy periods of weather in the past the Met Office’s National Climate Information Centre has done an analysis of the number of weather stations in the UK which have registered winds over certain thresholds since the start of December. This measure suggests that December 2013 is the stormiest December in records dating back to 1969 and is one of the windiest calendar months for the UK since January 1993. December was also a very wet month across the UK, particularly in Scotland where it was the wettest December and wettest month overall in the records dating back to 1910.

1900hurricane Posted January 5, 2014 Share Posted January 5, 2014 18Z GFS analyzed a doozy. It might not be as deep as the Christmas Eve bomb, but this one seems to have been packing the biggest punch. Say what you want about the naming of extratropical cyclones, but Hercules is certainly a fitting name for this one. Out of curiosity, does anyone know if there is any good visible images of this storm from today, particularly during the 15-18Z time period?

jgf Posted January 5, 2014 Share Posted January 5, 2014 i haven't seen this ASCAT presentation - where is it from? i usually just use the KNMI site at http://www.knmi.nl/scatterometer/ Satellite confirmed 80kt surface winds.
