This is a page about the low unofficially called 90L by users on Weather Underground. This actually attempted to become a subtropical storm in mid-January.

VISIBLE IMAGES AND SHIP OBSERVATIONS SUGGEST A NEWLY FORMED SFC LOW...ANALYZED 1012 MB NEAR 26N57W. IR IMAGERY AND LIGHTNING DATA INDICATE SCATTERED SHOWERS AND TSTMS TO THE E OF THE SFC LOW FROM 22N-27N BETWEEN 51W-55W.

 * January 12, 2008 0000 UTC

A 1009 MB LOW IS OVER THE CENTRAL ATLANTIC NEAR 27N59W. THE LOW WAS ALONG A SURFACE TROUGH WHICH EXTENDED FROM 32N58W S TOWARD THE LEEWARD ISLANDS TO 19N62W.
 * January 12, 2008 0600 UTC

A 1013 MB LOW IS OVER THE CENTRAL ATLANTIC NEAR 27N59.5W. THE LOW WAS ALONG A SURFACE TROUGH WHICH EXTENDED FROM 31N60W S TO 22N59W. SURFACE RIDGE COVERED THE ATLANTIC N AND W OF THE SURFACE LOW.
 * January 12, 2008 1200 UTC

A 1012 MB LOW IS NEARLY STATIONARY NEAR 27N60W. A SURFACE RIDGE SPANS THE SUBTROPICAL ATLANTIC N AND W OF THE SURFACE LOW.

A WEAK 1013 MB LOW PRES SYSTEM IS DRIFTING N CENTERED NEAR 27N60W. WHILE THE LOW-LEVEL CIRCULATION IS EASILY EVIDENT...THE SYSTEM IS DEVOID OF CONVECTION. AN EARLIER ASCAT PASS CAPTURED THE CIRCULATION WELL REVEALING WINDS MOSTLY LESS THAN 20 KT. NWP MODELS SHOW A CONTINUED NWD DRIFT AS IT OPENS INTO A TROUGH OVER THE NEXT DAY OR TWO...EVENTUALLY BEING ABSORBED BY A MUCH LARGER EXTRATROPICAL LOW.

A WEAK 1013 MB LOW PRES SYSTEM IS DRIFTING N AND WAS CENTERED NEAR 27N60W. WHILE THE LOW-LEVEL CIRCULATION IS EASILY EVIDENT...THE SYSTEM IS DEVOID OF DEEP CONVECTION. A 0044 UTC ASCAT PASS CAPTURED THE CIRCULATION WELL REVEALING WINDS OF UP TO 20 KT MAINLY IN THE EASTERN SEMICIRCLE. NWP MODELS SHOW A CONTINUED NORTH-NORTHWEST DRIFT AS IT OPENS INTO A TROUGH OVER THE NEXT DAY OR TWO... EVENTUALLY BEING ABSORBED BY A MUCH LARGER EXTRATROPICAL LOW. OVERCAST MULTILAYERED CLOUDS WITH EMBEDDED SCATTERED SHOWERS/ ISOLATED TSTMS LIE WELL TO THE E OF THE SFC LOW FROM 22N-30N BETWEEN 45W-51W IN AN UPPER DIFFLUENT ZONE.

A WEAK 1012 MB LOW PRES SYSTEM IS DRIFTING N AND WAS CENTERED NEAR 28N60W. THE LOW-LEVEL CIRCULATION IS EASILY EVIDENT WITH A CLUSTER OF DEEP CONVECTION FIRING UP ABOUT 90 NM FROM THE LOW LEVEL CENTER IN THE E SEMICIRCLE. THE MOST RECENT SCATTEROMETER PASS...A 0044 UTC ASCAT PASS CAPTURED THE CIRCULATION WELL REVEALING WINDS OF UP TO 20 KT MAINLY IN THE EASTERN SEMICIRCLE. NWP MODELS SHOW A CONTINUED NORTHWARD DRIFT AS IT OPENS INTO A TROUGH OVER THE NEXT DAY OR TWO...EVENTUALLY BEING ABSORBED BY A MUCH LARGER EXTRATROPICAL LOW EXPECTED TO INTENSIFY OFF THE MID ATLANTIC COAST TONIGHT AND MONDAY. OVERCAST MULTILAYERED CLOUDS WITH EMBEDDED SCATTERED SHOWERS/ ISOLATED TSTMS LIE WELL TO THE E OF THE SFC LOW FROM 22N-30N BETWEEN 45W-51W IN AN UPPER DIFFLUENT ZONE.

A 1010 MB LOW IS IN THE W/CENTRAL ATLC NEAR 27N60W WITH A SURFACE TROUGH EXTENDING S TO 23N61W AND SCATTERED SHOWERS TO THE E FROM 26N-29W BETWEEN 57W-59W. THIS SURFACE LOW WAS PREVIOUSLY ASSOCIATED WITH AN UPPER LOW THAT HAS WEAKENED OVER THE PAST SEVERAL HOURS. THE UPPER TROUGH REMAINS IN THE W/CENTRAL ATLC EXTENDING THROUGH 32N55W SSE TO 18N47W. A 1019 MB HIGH IS NEAR 29N70W AND WEAK SURFACE RIDGE IS BETWEEN THE SURFACE LOW AND THE FRONTAL BOUNDARY OVER THE FAR W ATLC.

A SLOWLY FILLING LOW PRES SYSTEM CONTINUES ITS NWD DRIFT CENTERED NEAR 29N60W. THE MIN PRES WAS LOWERED TO 1010 MB BASED ON EARLIER SHIP REPORTS. A SMALL PATCH OF MODERATE CONVECTION IS LOCATED TO THE SE OF THE CENTER WITHIN 60 NM OF 27.5N58W. THIS FEATURE IS EXPECTED TO OPEN INTO A TROUGH LATER TONIGHT OR TOMORROW AND BECOME ABSORBED BY THE MUCH LARGER AFOREMENTIONED WINTER STORM.

AHEAD OF THE FRONT...A WEAKENING 1012 MB LOW NEAR 29N60W IS DRIFTING SLOWLY N/NNE INTO THE OPEN CNTRL ATLANTIC. VIS SATELLITE PHOTOS SHOW ONLY A SWIRL OF LOW CLOUD CLOUDS ASSOCIATED WITH THIS FEATURE...AND THE FORECAST CALLS FOR IT TO BECOME ABSORBED DURING THE NEXT 24 HOURS OR SO.
 * January 14, 2008 1800 UTC

A 1014 MB LOW IS ALSO SE OF BERMUDA NEAR 29N60W DRIFTING NE. SATELLITE IMAGERY SHOWS ONLY A SWIRL OF LOW CLOUD CLOUDS WITH THIS FEATURE.

THE CYCLONIC CIRCULATION CENTER ON WATER VAPOR IMAGERY NEAR 31N53W HAS BEEN ASSOCIATED WITH THE 1014 MB SURFACE LOW PRESSURE CENTER NEAR 31N59W.
 * January 15, 2008 0600 UTC

THE LOW PRESSURE CENTER THAT WAS NEAR 31N60W EARLIER HAS DISSIPATED LEAVING ONLY A TROUGH ALONG 32N57W 27N60W.
