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 11, 2008 0000 UTC

A 1011 MB LOW IS OVER THE CENTRAL ATLANTIC NEAR 26N57W.

A SURFACE TROUGH EXTENDS FROM A 1009 MB LOW NEAR 26N58W S TO 20N59W.

• January 11, 2008 1200 UTC

A SURFACE TROUGH EXTENDS FROM 32N53W THROUGH A 1010 MB LOW NEAR 26N58W TO 20N62W.

A 1009 MB LOW IS OVER THE CENTRAL ATLANTIC NEAR 27N59W.

• January 12, 2008 0600 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 1200 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 1800 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.

• January 13, 2008 1200 UTC

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.

• January 13, 2008 1800 UTC

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.

A 1012 MB LOW PRESSURE CENTER IS NEAR 28N60W.

• January 14, 2008 1800 UTC

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 15, 2008 0000 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.

• January 15, 2008 0600 UTC

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 1200 UTC- dissipated

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