AvantHiatus Posted August 22, 2014 Share Posted August 22, 2014 The 0Z Euro says recurve east of the U.S. once more. That means the GFS and Euro have been consistently calling for a recurve since 0Z yesterday. Day 5 looks interesting, same general setup as 12z with the displaced ridge. Perhaps not an all clear for the East Coast and Canada. Link to comment Share on other sites More sharing options...
GaWx Posted August 22, 2014 Share Posted August 22, 2014 Day 5 looks interesting, same general setup as 12z with the displaced ridge. Perhaps not an all clear for the East Coast and Canada. Fwiw, it is staying offshore NC northward to N.E. on the 0Z Euro. However, it certainly isn't an all clear for the east coast/Canada. JB emphasizes that due to the displaced ridge. Edit: The GFS/Euro have been pretty consistently generating a TC in the far eastern Atlantic ~8/27 moving NW to NNW fwiw. Link to comment Share on other sites More sharing options...

Kory Posted August 22, 2014 Share Posted August 22, 2014 Seems to be a center relocation south of Puerto rico right now, could this somehow go south of Hispaniola Yeah, I see a distinct spin around 65W and 15-16N. The GFS looks to have initialized there. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted August 22, 2014 Share Posted August 22, 2014 The surface flow with 96L is still sloppy. The vortex seen yesterday moving northwestward to the northeast of the islands has not become anything more than an eddy in the larger open circulation. The eddy is still there, north of the Virgin Islands, moving wnw/w. Regardless how the system tries to organize, the models have been getting even more robust with the trough off the east coast. It'll be tough for anything to get passed it. Link to comment Share on other sites More sharing options...
Srain Posted August 22, 2014 Share Posted August 22, 2014 Radar from San Juan is far better than looking at satellite loops at this time. As RECON detected yesterday, there were two vorts observed with the one to the SW being the weaker of the two. The northern most spin was clearly visible on high resolution imagery when it was devoid of convection. Link to comment Share on other sites More sharing options...
Kory Posted August 22, 2014 Share Posted August 22, 2014 Perhaps these 2 circulations is what the ECMWF has been showing with a bifurcation of 96L's energy. It shows a piece recurving with it off the East Coast and another making it's way into the Gulf. Link to comment Share on other sites More sharing options...
phil882 Posted August 22, 2014 Share Posted August 22, 2014 Perhaps these 2 circulations is what the ECMWF has been showing with a bifurcation of 96L's energy. It shows a piece recurving with it off the East Coast and another making it's way into the Gulf. Well I think this is more of a manifestation of the large uncertainty surrounding the forecast location of 96L in the medium range. While there might be more members in the northern camp (can't tell for sure unless I had the actual ensemble model guidance), its obvious there are still a non-negliable amount of ensemble members that take 96L into the Gulf of Mexico. The llc associated with 96L is still very broad (although the dominant mesovort appears to be just N of Puerto Rico), and relocations are difficult to forecast with large systems such as this. It still might be another 24 hours (after it gets past Hispaniola) until we really know that this poleward solution is the way to go. Link to comment Share on other sites More sharing options...
packbacker Posted August 22, 2014 Share Posted August 22, 2014 12z early model guidance sure ticked up in intensity and still a ton of spread among the members, several show potential E-US landfall. Link to comment Share on other sites More sharing options...

CCHurricane Posted August 22, 2014 Share Posted August 22, 2014 06Z GFDL is pretty good weenie-bait now - heading for the Chesapeake. Seems that its only showing a weak Cat 1 at that time though and the Hurricane force winds should be off shore. Seems to be more of an issue for the Northeast than Chesapeake.

CCHurricane Posted August 22, 2014 Share Posted August 22, 2014 Also has outrageous convection well NE of the system. I would throw this run out. Not because it doesn't show what I want, but b/c it blows up a secondary low northeast of the hurricane center. Just makes no sense to me. Link to comment Share on other sites More sharing options...
Kory Posted August 22, 2014 Share Posted August 22, 2014 Also has outrageous convection well NE of the system. That's the main reason why it shows an out to sea solution. The LLC follows the heaviest convection. We've seen it before like with Debby in 2012 where the center kept reforming NE following the heaviest convection.

CCHurricane Posted August 22, 2014 Share Posted August 22, 2014 HWRF went further east on the 6z run: slp20.png I understand that, but that shift east is from the 00z run to the 06z run. The map in question is listed as 12z guidance and I am just wondering why they include 06z model runs on that map. Link to comment Share on other sites More sharing options...
