phil882 Posted October 10, 2014 Share Posted October 10, 2014 90L is really the system to watch the next several days. Its going to have to thread the needle shear wise for the next couple of days, but its probably the only system that has a realistic (although still small) chance of impacting the US.

Showers and thunderstorms have become a little better organized inassociation with a tropical wave located about 600 miles east of theLesser Antilles. Further development is possible over theweekend, with environmental conditions becoming more conducive fortropical cyclone formation by early next week.

Visible loop shows high clouds racing off toward the north west, arc clouds to the south-southwest and two interesting little surface vortices rotating around in the overall circulation. Dude, it's a subtropical cyclone. This is normal. "Dude", one of the reasons for my original post was to point out some interesting features in the visible loop for STD-07 (especially since we've had such a boring period recently in the Atlantic). Yes, in addition I was also noting these things as reasons for it not yet being fully tropical. Sorry if for whatever reason it offended you. As I expected yesterday; STD-07 has now become fully tropical despite still dealing with the dry air and shear, but thanks for your post, "Dude". TROPICAL STORM FAY DISCUSSION NUMBER 6NWS NATIONAL HURRICANE CENTER MIAMI FL AL0720141100 AM AST SAT OCT 11 2014Tropical Storm Fay made the transition to a tropical cyclone around0600 UTC based on AMSU and other satellite data that arrived afterthe previous advisory was released. An Air Force Reservereconnaissance aircraft confirmed this transition had occurred, whenit made a pass through the northwestern and northern quadrantsindicating that the radius of maximum wind had decreased to about 40n mi. A blend of satellite intensity estimates, flight-level surfacewind conversions, and reliable SFMR surface winds support increasingthe intensity to 60 kt. The latest center dropsonde data suggests acentral pressure of about 991 mb.The initial motion estimate is 355/14. Other than the centerredeveloping a little farther west and closer to the deepconvection, the overall track forecast and reasoning remainsunchanged form the previous advisory. Fay is expected to continue tomove northward and then northeastward around the western peripheryof a strong mid-level ridge for the next 24 hours or so, and thenrecurve into the mid-latitude westerlies with an increase inforward speed by 36 hours. The official track forecast closelyfollows the multi-model consensus TVCN.The strength and direction of the current vertical wind shear isforecast to remain unchanged for the next 24 hours, so no change inintensity indicated during that time. By 36 hours, the shear isforecast to increase to more than 40 kt from the southwest, whichshould induce a weakening trend until the cyclone is absorbed by astrong cold front in about 48 hours.FORECAST POSITIONS AND MAX WINDSINIT 11/1500Z 27.9N 65.3W 60 KT 70 MPH 12H 12/0000Z 30.1N 65.2W 60 KT 70 MPH 24H 12/1200Z 33.0N 62.7W 60 KT 70 MPH 36H 13/0000Z 35.3N 58.0W 55 KT 65 MPH 48H 13/1200Z...ABSORBED BY FRONTAL SYSTEM Link to comment Share on other sites More sharing options...

GaWx Posted October 12, 2014 Share Posted October 12, 2014 Invest 90L is looking pretty organized already. This could be declared a TD by tomorrow. October is suddenly not looking so boring with at least two systems to this point. Also, 91L to the east has a small chance. The CONUS shouldn't be threatened imo by any of these three regardless. This will be interesting for our contest. Edit: The 0Z Euro is again showing a sig. TC just east of the Bahamas by late week from 90L. The CONUS has little chance to be threatened by 90L imo as I don't see the ridging to its north needed to give it a westerly enough component toward the east coast. However, it is still too early to be ~100% confident. Link to comment Share on other sites More sharing options...

wxtrackercody Posted October 12, 2014 Share Posted October 12, 2014 The 18z Best Track has raised Fay to hurricane intensity...if anyone cares. Not too surprising since the overall cloud pattern has become more symmetrical since this morning. On its closest pass to Bermuda, Fay produced sustained winds of 61 mph with gusts up to 82 mph. Sustained winds of 81 mph with gusts to 109 mph were recorded at 140ft. Link to comment Share on other sites More sharing options...
bluewave Posted October 12, 2014 Share Posted October 12, 2014 It took the recent SST rise over the Tropical Atlantic for Gonzalo to have a shot at being the strongest storm of the season south of 25N. Link to comment Share on other sites More sharing options...
GaWx Posted October 12, 2014 Share Posted October 12, 2014 Fay has just been officially designated the 5th hurricane of the Atlantic season, which makes sense in retrospect considering that Bermuda took a pretty significant blow. Gonzalo could end up as the 6th, which would mean we'd be closing in on a normal season in terms of # of H's. Link to comment Share on other sites More sharing options...
Amped Posted October 12, 2014 Share Posted October 12, 2014 Looks like we have a late active period in the basin. Gonzalo could be our second Major hurricane. Euro shows a central Atlantic subtropical storm and GFS shows a W Caribbean storm (again) in the long range. Link to comment Share on other sites More sharing options...
hurricaneman Posted October 14, 2014 Author Share Posted October 14, 2014 All the models are showing a low in the BOC at about 168hrs and coming from the EPAC , might be something to watch in the next week or so but with these type of Gyres it could form in th SW Caribbean, NW Caribbean or southern GOM also so thats another thing to watch for Link to comment Share on other sites More sharing options...
Carvers Gap Posted October 14, 2014 Share Posted October 14, 2014 The 18z GFS and 12z Euro seem to use a deep trough to pull a GOM system into FL and string it along the East coast much of next week.
