 POST-TROPICAL CYCLONE MIRIAM DISCUSSION NUMBER  25
 NWS NATIONAL HURRICANE CENTER MIAMI FL       EP132012
 800 PM PDT THU SEP 27 2012
  
 MIRIAM HAS NOT PRODUCED DEEP CONVECTION FOR ABOUT 12 TO 15 HOURS...
 AND IT THEREFORE NO LONGER QUALIFIES AS A TROPICAL CYCLONE.  MIRIAM
 HAS BECOME A REMNANT LOW...AND THIS IS THE LAST ADVISORY THAT NHC
 WILL ISSUE.  THE ADVISORY INTENSITY IS BEING HELD AT 30 KT BASED ON
 AN EARLIER ASCAT PASS...BUT THE WINDS WILL CONTINUE TO DECREASE AS
 THE CYCLONE REMAINS OVER COLD WATER.  DISSIPATION IS FORECAST IN
 ABOUT 3 DAYS.
 
 MIRIAM HAS BEEN NEARLY STATIONARY SINCE THE LAST ADVISORY...BUT THE
 REMNANT LOW IS EXPECTED TO DRIFT SOUTHWARD DURING THE NEXT FEW DAYS
 SINCE IT IS BEING BLOCKED BY A LOW-LEVEL RIDGE TO ITS NORTH.  THE
 UPDATED NHC TRACK FORECAST IS LARGELY UNCHANGED FROM THE PREVIOUS
 ONE.
 
 THE CENTRAL PRESSURE OF MIRIAM WAS LOWERED DUE TO A REPORT OF 1000.2
 MB AND 24 KT OF WIND FROM THE SHIP MONTE VERDE...DCPC2.
