Here we discuss interesting North Atlantic features outside the deep tropics and in the off season. If you've got a favorite, post it. If you've got surface or upper air charts for the open Atlantic for this time period, or analysis of any interesting event, by all means post 'em. Click the dates to browse the systems yourself in the GIBBS browser. I will probably add to the list later, changing text color to indicate a new addition.
LONG POST AHEAD, BROWSERS BEWARE.

January 13, 1980
Large nor'easter stalled south of Nova Scotia and developed convection near center, weakening and dropping south leaving a naked swirl
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1981-3-5.jpg)
March 5, 1981
Quick-developing midlatitude low with an eye on the 4th develops convection briefly on the 5th
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1982-1-26.jpg)
January 25, 1982
Neat clear center in this one.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1982-10-12.jpg)
October 12, 1982
Open Atlantic gale stalls and develops a persistent center and eye
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1982-11-26.jpg)
November 23-29, 1982
POSSIBLE TS/STS? Looks to be a frontal low that stalled and drifted south over the far east Atlantic. Developed and maintained relatively deep convection and what looks to be a low level center and even occasionally an eye. A candidate for a closer look, despite its location
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1983-2-21.jpg)
February 20-23, 1983
POSSIBLE TS/STS? This one jumped out at me. Nor'easter stalls offshore and develops convection and low level center underneath which loops counterclockwise around the larger center, briefly developing an eye feature with the curved bands clearly visible on IR.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1983-3-5.jpg)
March 5, 1983
Occluded frontal low drifting across east Atlantic. Had convection and perhaps a lower level center for several hours
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1983-9-24.jpg)
September 23-25, 1983
POSSIBLE TS/STS? Moooore 1983. Looks like a small low level center with convection rapidly developing and rotating counterclockwise around the center of a larger occluded low behind a front. Poor resolution but perhaps a brief eye on the 24th.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1983-11-20.jpg)
November 18-22, 1983
Fascinating little micro-system! Loop Nov 20-22 on IR and WATCH CAREFULLY. Tiny persistent convection about the size of a single thunderstorm that is clearly cyclonic, rotating inside a dying larger scale system and making landfall in Portugal. The heck is this?
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1986-4-20.jpg)
April 20, 1986
Center of a mid-latitude system develops convection at center after stalling offshore
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1989-1-23.jpg)
January 23, 1989
Midlatitude system develops a convective vortex just offshore. Could've become a subtropical candidate if it had persisted longer. Very similar to a May 7, 2005 storm. The Gulf Stream works wonders I guess
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1989-9-30.jpg)
September 26-October 2, 1989
POSSIBLE TS/STS? Cut-off and stalling small low develops dense convection and apparently a lower level center. Lasts a few days
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1991-12-23.jpg)
December 23, 1991
Big mid-latitude gale with some convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1992-1-3.jpg)
Jaunary 3, 1992
Deep convection around a Gulf system sweeping into the Atlantic, the first of multiple interesting systems of 1992
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1992-5-12.jpg)
May 12, 1992
Brief stalled low off East Coast
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1992-9-12.jpg)
September 12, 1992
POSSIBLE TS? this one has been talked about on here before. Brief system possibly a tropical storm passing just south of Nova Scotia.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1993-3-13.jpg)
March 13, 1993
I mean, I HAVE to post the Blizzard of 93. Wish I were old enough at the time to remember the heckin' foot of snow it brought to AL.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1993-9-18.jpg)
September 17-22, 1993
Wouldn't be shocked if this apparently front-borne tiny little clockwise looping system was very briefly classifiable, before convection died off. The remnant low level center can be seen drifting S/SW for a couple more days.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1993-10-30.jpg)
October 30, 1993
I love the symmetry and shape of this. The Azores to Portugal are apparently very neat to watch
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1993-12-14.jpg)
December 14, 1993
Nor'easter briefly developing deep convection stalled over the Gulf Stream
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1994-4-6.jpg)
April 6, 1994
Mid-Atlantic gale center very briefly tries to develop convection, seems to have a small low level swirl after being sheared off
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1994-4-16b.jpg)
April 16, 1994
Shortly after previous system, occluded low from a front west of Canary Islands briefly develops deep convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1994-10-12.jpg)
October 12, 1994
Neat very high latitude occluded low retrograding west
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1994-12-17.jpg)
December 17, 1994
Atlantic stalled midlatitude cyclone with convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1994-12-22.jpg)
December 22-25, 1994
POSSIBLE STS? Commonly discussed here, "Hurricane Santa" was a Christmas nor'easter that had subtropical characteristics after the developing system moved out of the Gulf and started heading up the East Coast. Even operationally considered perhaps subtropical, and will possibly be added in reanalysis.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1995-3-26.jpg)
March 26, 1995
Brief convection in a gale center in the northeast Atlantic
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1995-9-24.jpg)
September 23-26, 1995
In the middle of the 1995 hurricane season, a nontropical low east of the remnants of Marilyn broke off a little blob with an apparent lower level circulation that moved NW and got absorbed by a front. If convection were more persistent it might've become a brief tropical depression
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1995-12-7.jpg)
November 7, 1995
Midlatitude systems starting to take over as that wild hurricane season ended
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1995-12-17b.jpg)
December 17, 1995
A little earlier, further south, and slower moving, and this might've developed into a late season STS
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1996-3-18.jpg)
March 18, 1996
Tiny low from a front develops a swirl and convection before being swept away
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1996-7-25.jpg)
July 25, 1996
Little vortex off East Coast, minimal convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1996-11-18.jpg)
November 17-21, 1996
PROBABLE TS/STS? Center of extratropical cyclone stalls over Gulf Stream. Loop the 17-21st; this was probably a briefly nameable system.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1997-2-3.jpg)
January 30-February 5, 1997
Stalled low west of the Canary Islands. Convection on the 3rd might make a case for TC/STC as the dissipating system showed a broad low level center, but lacked persistence
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1997-4-9.jpg)
April 9, 1997
Very big eastern Atlantic gale
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1995-10-26.jpg)
October 24-27, 1997
POSSIBLE TS/STS? Small low making couter-clockwise curve over Azores. Very obvious eye just offshore Portugal on the 26th.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1997-11-06.jpg)
November 5, 1997
Large east Atlantic system
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1998-3-9.jpg)
March 9, 1998
Big east Atlantic low with convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1998-3-23.jpg)
March 23, 1998
Deep convection was briefly present later that night over this; micro scale features are hard to see in this resolution
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1998-11-5.jpg)
November 5, 1998
Deep convection briefly present over a low in the eastern Atlantic
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1998-12-20.jpg)
December 20, 1998
Little low level swirl diving S then W well east of the Lesser Antilles
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1999-7-25.jpg)
July 25, 1999
Impressive looking midlatitude cyclone for July
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1999-9-10.jpg)
September 10, 1999
Small convective swirl looks to be the lovechild of remnant energy from Hurricane Cindy and a midlatitude system
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/1999-11-30.jpg)
November 30, 1999
East Atlantic system celebrating the last day of hurricane season. Pretty certain involved with the remnants of Lenny
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2000-1-27.jpg)
January 26-27, 2000
Small low west of Canary Islands
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2000-2-29.jpg)
February 29, 2000
Brief convection in center of gale east of Newfoundland
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2001-4-9.jpg)
April 9, 2001
This one's pretty.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2001-11-18.jpg)
November 16-18, 2001
November 2001 was VERY active with a record three hurricanes, but even between Michelle/Noel and Olga there was activity. Dunno if we'll see a November like that one (and 2005) anytime soon
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2001-12-26.jpg)
December 26, 2001
Wannabe Olga 2.0, but not happenin'.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2002-2-16.jpg)
February 18, 2002
Lots of vortices travel the offshore waters near Morocco; this one is unusually long lasting and with scattered convection
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2003-4-1.jpg)
April 1, 2003
Tropical Storm Ana is famous for developing in April 2003, but three weeks prior to that, this thing started trying to as well. Fell way short of course, but still
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2005-5-7.jpg)
May 7, 2005
Developed off the Carolina coast under a large extratropical cyclone. Briefly had an eye that night, but a very short lived system
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2005-6-2.jpg)
June 2-4, 2005
Convection and perhaps a low level swirl inside a big midlatitude low. Feature lasted three days; a slower movement and this could've perhaps become subtropical. Not on the TWO.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2006-6-3.jpg)
June 3, 2006
Neat gale center a year after that one
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2007-8-31.jpg)
August 30-31, 2007
Center of a storm system east of Newfoundland. Would love to see this one in higher res as that little area of convection persisted a couple days and IR suggests maybe a low level center. It sticks out for sure. Closely monitored on the TWO for a day.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2007-9-9.jpg)
September 9, 2007
A stationary low in the same place... just a week later
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2007-10-6.jpg)
October 6, 2007
Occluded low near the Azores, a hotbed of neat satellite shots
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2007-12-28.jpg)
December 28, 2007
Can't say for sure, but seems like I remember watching this East Atlantic feature... wow 12 years goes fast
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2008-2-15.jpg)
February 15, 2008
Moooooore East Atlantic action near Azores
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2008-3-6.jpg)
March 6, 2008
You guessed it, more East Atlantic stuff
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2008-4-29.jpg)
April 29, 2008
Small convective swirl rotating counterclockwise around the center of a large gale S of Newfoundland. IF this had a LLC, this would be very interesting...
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2008-11-28.jpg)
November 28-29, 2008
Watch this get pulled into the approaching front... very neat. Was on the TWO with a low chance. Stayed intact for a bit even after.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2009-6-1.jpg?)
May 30-June 4, 2009
Possible TS/STS? Not sure if fully separated from parent storm, buuut that looks a lot like an eye over the Azores on visible, IR, and WV on the 1st and convection remains deep on the 2nd. On the NHC TWO with a low chance.
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2009-11-1.jpg)
November 1-3, 2009
East of Bermuda, was on TWO with a high chance of becoming a subtropical storm but kept surface frontal attachment then lost convection over the LLC. Had trouble ever regaining that
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2010-1-31.jpg)
January 30-February 1, 2010
Possible TS/STS? Deep convection persists over small low west of Canary Islands
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2010-4-25.jpg)
April 25, 2010
Big storm system S and SE of Atlantic Canada
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2011-11-21.jpg)
November 21, 2011
System east of Bermuda, this was on the TWO for a few days with a high chance of becoming a subtropical storm but became a frontal low without ever acquiring a well defined surface center
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2012-3-10.jpg)
March 10, 2012
Big low pressure center near Azores, swirls rotating counterclockwise within
![Image](https://horsesnhurricanes.files.wordpress.com/2019/11/2014-1-13.jpg)
January 13, 2015
Big ol' storm system west of Canary Islands
--------------------
Sooooo.... in conclusion, watching satellite imagery over any ocean basin is pretty fascinating, and yeah there are surely a couple of high latitude Atlantic subtropical storms here and there that weren't classified then that would be named if they had happened this year, now that technology to analyze them is better and the criterion for classification is slightly looser. Any thoughts or analysis? Which systems piqued your interest? Got something even more impressive that my tired mind missed when scanning through thirty-four years of satellite data??
