NWS NATIONAL HURRICANE CENTER MIAMI FL       EP122012
800 AM PDT WED SEP 19 2012
 
LANE HAS BEEN DEVOID OF ANY DEEP CONVECTION FOR ABOUT 12 HOURS
NOW...AND IS THEREFORE BEING DESIGNATED AS A POST-TROPICAL REMNANT
LOW. BASED ON A 19/0546 UTC ASCAT OVERPASS...WHICH CAUGHT THE WEST
SIDE OF THE INNER-CORE CIRCULATION TO WITHIN 25 N MI OF THE
CENTER...SUPPORTS HOLDING THE INTENSITY AT 30 KT FOR THIS ADVISORY. 
THE CYCLONE SHOULD CONTINUE TO SPIN DOWN AND DISSIPATE ENTIRELY IN
A COUPLE OF DAYS AS IT CONTINUES TO MOVE THROUGH AN EXTENSIVE FIELD
OF STRATOCUMULUS CLOUDS AND REMAINS OVER SUB-22C SSTS.

THE REMNANT LOW CONTINUES TO TURN TO THE LEFT AND IS NOW MOVING
WESTWARD AT ABOUT 280/5. THE VERTICALLY SHALLOW CYCLONE SHOULD
CONTINUE TO MOVE SLOWLY WESTWARD UNDER THE INFLUENCE OF EASTERLY
TRADE WIND FLOW FOR THE NEXT 36 HOURS OR UNTIL DISSIPATION OCCURS.
THE OFFICIAL FORECAST TRACK IS CLOSE TO THE PREVIOUS ONE...AND IS
ROUGHLY IN THE MIDDLE OF THE TIGHTLY PACKED NHC TRACK GUIDANCE.

THIS IS THE LAST ADVISORY ON THIS SYSTEM. FOR ADDITIONAL INFORMATION
