This is the summary of the low that attempted to become a tropical or subtropical storm on March 6 and 7, 2008.
- March 5, 2008 1800 UTC
A 1007 MB LOW IS N OF THE AREA OVER THE CENTRAL ATLANTIC NEAR 35N36W.
- March 6, 2008 0000 UTC
E OF THERE...THE MAIN FEATURE IS A 1009 MB LOW DROPPING SWD INTO THE AREA NEAR 33N38W. AN OCCLUDED FRONT WRAPS ON THE E SIDE OF THE LOW FROM 32N34W TO 30N34W THEN CONTINUES SW AS A COLD FRONT TO 24N43W.
- March 6, 2008 0600 UTC
E OF THE RIDGE A 1008 MB LOW PRES IS MOVING SWD INTO THE AREA NEAR 32N37W. AN OCCLUDED FRONT WRAPS ON THE NE SIDE OF THE LOW FROM 34N33W THEN BECOMES A COLD FRONT TO 30N32W TO 25N46W.
- March 6, 2008 1200 UTC
E OF THE RIDGE A 1007 MB LOW PRES IS CENTERED NEAR 29N30W. AN OCCLUDED FRONT WRAPS ON THE NE SIDE OF THE LOW FROM 34N33W TO 32N32W THEN BECOMES A COLD FRONT TO 25N35W TO 25N43W. SCATTERED SHOWERS AND TSTMS ARE WITHIN 180 NM E SEMICIRCLE OF THE LOW. THE TIGHT PRES GRADIENT BETWEEN THIS LOW AND THE RIDGE ACROSS THE CENTRAL ATLC IS PRODUCING GALE FORCE WINDS TO THE W OF THE LOW.
- March 6, 2008 1800 UTC
THE 1006 MB LOW PRESSURE CENTER NEAR 28N37W IS HELPING TO PRODUCE GALE-FORCE WINDS TO THE WEST OF THE LOW...PLEASE REFER TO THE MIAHSFAT2 FOR MORE DETAILS.
- March 7, 2008 0000 UTC
THE MAIN FEATURE IN THE E ATLC IS A 1006 MB LOW SPINNING NEAR 28N37W. THIS DEEP LAYER LOW IS CUT OFF FROM THE PROGRESSIVE PATTERN ALLOWING IT TO BE QUASI-STATIONARY. SCATTERED SHOWERS AND TSTMS ARE MOST ORGANIZED N OF THE LOW FROM 30N-32N BETWEEN 34W-38W. THIS LOW APPEARS OCCLUDED IN NATURE SO WILL LIKELY REPRESENT THAT WITH AN OCCLUDED FRONT WRAPPING AROUND THE LOW TRANSITIONING TO A COLD FRONT FROM 28N35W TO 24N46W. SCATTERED SHOWERS ARE POSSIBLE WITHIN 120 NM E OF THE FRONT AND ELSEWHERE WITHIN 240 NM OF THE LOW. GALE CONDITIONS ARE STILL OCCURRING TO THE W OF THE LOW DUE TO THE TIGHT PRES GRADIENT BETWEEN IT AND THE 1029 MB HIGH TO THE W. UPPER SWLY FLOW OVER THE REMAINDER OF THE TROPICAL/SUBTROPICAL E ATLC IS ADVECTING PATCHY HIGH LEVEL CLOUDS BUT OVERALL LITTLE SIGNIFICANT WEATHER. CONVECTION IN THE ITCZ IS CONSIDERABLY SUBDUED TODAY COMPARED TO THE PAST COUPLE OF DAYS.
- March 7, 2008 0600 UTC
THE 1005 MB LOW PRESSURE CENTER NEAR 28N37W IS HELPING TO PRODUCE GALE-FORCE WINDS TO THE WEST OF THE LOW...PLEASE REFER TO THE MIAHSFAT2 FOR MORE DETAILS.

- March 7, 2008 1800 UTC
THE MAIN WEATHER FEATURE ACROSS THE FORECAST AREA IS A 1005 MB LOW SPINNING NEAR 28N37W. THIS LOW REMAINS QUASI-STATIONARY. THE AIR MASS AROUND THIS LOW HAS BECOME MORE HOMOGENEOUS DURING THE LAST 24 HOURS...AND THERE ARE NO FRONTS ASSOCIATED WITH THIS CYCLONE ANY LONGER. INSTEAD...A SFC TROUGH IS ANALYZED FROM THE SFC LOW TO 20N41W. SCATTERED SHOWERS AND TSTMS ARE MOST ORGANIZED IN BANDS N AND NE OF THE LOW. TIGHT PRES GRADIENT BETWEEN THIS CYCLONE AND HIGH PRES OVER THE CENTRAL ATLC IS PRODUCING A LARGE AREA OF MODERATE TO STRONG NE WINDS IN THE NW SEMICIRCLE OF THE LOW. ACCORDING TO THE GFS COMPUTER MODEL...THE LOW WILL SLOWLY DRIFT SW AND WEAKEN DURING THIS WEEKEND.
- March 8, 2008 0000 UTC
THE OTHER AREA OF ACTIVE WEATHER IS ASSOCIATED WITH A NEARLY STATIONARY 1005 MB LOW NEAR 29N38W. THIS ONCE OCCLUDED SYSTEM HAS LOST MUCH OF ITS FRONTAL BOUNDARIES WITH ONLY A TROUGH ANALYZED SWD FROM THE LOW TO 23N41W. CONVECTION IS SCATTERED IN NATURE WITHIN 420 NM N AND NE OF THE CENTER. GALE FORCE WINDS ARE STILL OCCURRING TO THE W OF THE LOW JUST N OF THE DISCUSSION AREA DUE TO THE TIGHT PRES GRADIENT BETWEEN THE LOW AND A 1030 MB HIGH NEAR 37N52W. MODEL GUIDANCE IS IN GOOD AGREEMENT SHOWING THIS CUT OFF SYSTEM DRIFTING TO THE SW AND WEAKENING THIS WEEKEND.
- March 8, 2008 0600 UTC
THE 1006 MB LOW PRESSURE CENTER NEAR 29N38W IS HELPING TO PRODUCE 25 KT TO 30 KT WINDS TO THE WEST OF THE LOW...PLEASE REFER TO THE MIAHSFAT2 FOR MORE DETAILS.
- March 8, 2008 1200 UTC
THE 1006 MB LOW PRESSURE CENTER NEAR 29N38W IS HELPING TO PRODUCE 25 KT TO 30 KT WINDS FROM THE LOW CENTER WESTWARD...PLEASE REFER TO THE MIAHSFAT2 FOR MORE DETAILS.
- March 8, 2008 1800 UTC
THE OTHER FEATURE OF INTEREST IS A 1011 MB LOW SPINNING NEAR 28N37W. THIS LOW REMAINS QUASI-STATIONARY AND HAS WEAKENED SINCE YESTERDAY. A SWIRL OF LOW CLOUDS DEFINES THE CYCLONE CENTER WITH SCATTERED SHOWERS AND PROBABLY ISOLATED TSTMS TO THE NE OF THE LOW. A SFC TROUGH EXTENDS FROM THE LOW SWWD TO 18N43W. TIGHT PRES GRADIENT BETWEEN THIS CYCLONIC CIRCULATION AND A 1031 MB HIGH PRES OVER THE CENTRAL ATLC IS PRODUCING A LARGE AREA OF MODERATE TO STRONG NE WINDS IN THE NW QUADRANT OF THE LOW. ACCORDING TO THE GFS COMPUTER MODEL...THE LOW WILL SLOWLY DRIFT SW AND CONTINUE TO WEAKEN DURING THE REST OF THE WEEKEND LEAVING AN OPEN SFC TROUGH.
- March 9, 2008 0000 UTC
A 1011 MB LOW IS CENTERED OVER THE CENTRAL ATLANTIC NEAR 27N38W. A SURFACE TROUGH EXTENDS SW FROM THE LOW TO 20N41W. EXPECT THIS SURFACE LOW TO MOVE SW TO 24N44W IN 24 HOURS.
- March 9, 2008 0600 UTC
THE GALE-FORCE WIND EVENT OF THE LAST FEW DAYS HAS ENDED. THE SURFACE LOW PRESSURE CENTER HAS WEAKENED COMPARATIVELY TO A 1013 MB LOW PRESSURE CENTER NEAR 27N38W. A TROUGH EXTENDS FROM THE LOW CENTER TO 23N44W.
- March 9, 2008 1200 UTC
THE GALE-FORCE WIND EVENT OF THE LAST FEW DAYS HAS ENDED. THE SURFACE LOW PRESSURE CENTER HAS WEAKENED COMPARATIVELY TO A 1016 MB LOW PRESSURE CENTER NEAR 27N40W.
- March 9, 2008 1800 UTC
THE ONLY OTHER AREA OF LOW PRES IS A WEAKENING 1016 MB LOW NEAR 26N40W. THIS LOW HAS GREATLY WEAKENED OVER THE PAST COUPLE OF DAYS NOW ONLY CONSISTING OF A SWIRL OF LOW CLOUDS. HOWEVER...THE TIGHT PRES GRADIENT ON THE N SIDE OF THE SYSTEM IS STILL PRODUCING STRONG NE WINDS AS REVEALED BY A QSCAT AND ASCAT PASS THIS MORNING. THIS WEAK SFC LOW IS EMBEDDED IN AN HIGHLY ELONGATED MID TO UPPER TROUGH.
- March 10, 2008 0000 UTC
A 1014 MB LOW IS CENTERED OVER THE CENTRAL ATLANTIC NEAR 27N42W.
- March 10, 2008 0600 UTC
A SURFACE TROUGH EXTENDS FROM 30N42W THROUGH A WEAK 1014 MB LOW NEAR 26N45W TO 20N45W BUT DUE TO THE STRONG SUBSIDENCE AND DRY STABLE AIR THAT DOMINATES THE CENTRAL ATLC THERE IS ONLY SCATTERED LOW CLOUDS PRESENT.
