VAsnowlvr82 Posted December 26, 2010 Share Posted December 26, 2010 Do you happen to know what the pressure was like an hour ago? Link to comment Share on other sites More sharing options...
Confuzzled Posted December 26, 2010 Author Share Posted December 26, 2010 I think it was even lower an hour ago (969), I went and checked a map I saved. I'm thinking bad data.... Went to the National Bouy Center... 29.47in and dropping rapidly....a couple hundred miles due east of myrtle beach is the lowsest I saw (998mb) http://www.ndbc.noaa.gov/ Link to comment Share on other sites More sharing options...
VAsnowlvr82 Posted December 26, 2010 Share Posted December 26, 2010 Yea that definitely sounds wacky. I think it was even lower an hour ago (969), I went and checked a map I saved.

wxnut Posted December 26, 2010 Share Posted December 26, 2010 Those are in tenths of mb... 969 means 996.9 mb Link to comment Share on other sites More sharing options...
Confuzzled Posted December 26, 2010 Author Share Posted December 26, 2010 Those are in tenths of mb... 969 means 996.9 mb I thought too, cool this is already decoded I haven't seen any pressure drops in the last hour or so there....the weenie in my is getting nervous.... Winds are gusting to 40knots in places though... Link to comment Share on other sites More sharing options...

Confuzzled Posted December 26, 2010 Author Share Posted December 26, 2010 29.41 lowest so far.......... 996mb.... http://www.ndbc.noaa.gov/station_page.php?station=41036 Link to comment Share on other sites More sharing options...
Kaner587 Posted December 26, 2010 Share Posted December 26, 2010 weenies not gonna like this; rapid drops well offshore its impossible to respond to all of these posts, but for the n-teenth time pressure falls dont show accurately where the low pressure center is OR what direction it is headed, especially in a situation such as this where there is going to be a turning from ENE to NE to NNE to N Link to comment Share on other sites More sharing options...

Kaner587 Posted December 26, 2010 Share Posted December 26, 2010 It is a 3 hr. trend, nothing more and nothing less correct, there are just a million weenies who'll jump on it and say ohh this is going east etc. Just setting the record straight Link to comment Share on other sites More sharing options...
snowfan Posted December 26, 2010 Share Posted December 26, 2010 Radar still having a hell of a time advancing past a line from Fredericksburg to St. Michaels to Dover/Wilmington. VaBeach, Williamsburg, Chesapeake.......thats the place to be at the moment.

thegreatdr Posted December 26, 2010 Share Posted December 26, 2010 This map implies a 986 low west of the buoy east of Cape Hatteras. A conservative estimate of central pressure is to start with the pressure nearest the low, and drop the value one millibar/hPa for every ten knots of wind. It's a practice HPC and OPC have done for over a decade (perhaps much longer) that TPC/NHC began to do with tropical cyclones during the decade of the naughts (2000-2009). This is another reason why the hurricane re-analysis for the Atlantic basin is sorely needed, even if it's taking a generation to accomplish. So far, the reanalysis has taken fourteen years and counting, In the second hour of white death, flurry-style, DR Seems like too sharp a pressure gradient to me but I could be wrong.....

In the "Eye" 05:04 37.6 °F 34.6 °F 28.56in Calm ... and to think everyone was picking on JB for not getting a landfalling hurricane this year in the USA. I wonder if he'll claim it as such for his verification score. LOL Link to comment Share on other sites More sharing options...
Confuzzled Posted December 27, 2010 Author Share Posted December 27, 2010 964 east of nantucket.... (28.48 and falling rapidly....) That cape pressure is very impressive for landfall.... Link to comment Share on other sites More sharing options...

Amped Posted December 27, 2010 Share Posted December 27, 2010 963.8 at ACK is the lowest I could find There was an eye that past S of AKC so upper 950s isn't out of the question. Link to comment Share on other sites More sharing options...
