ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM TROPICAL DEPRESSION ROSA DISCUSSION NUMBER 22 NWS NATIONAL HURRICANE CENTER MIAMI FL EP172012 700 AM PST SUN NOV 04 2012 DEEP CONVECTION HAS RETURNED OVER THE EASTERN PORTION OF THE CIRCULATION OF ROSA OF THIS MORNING. HOWEVER...THIS RECENT INCREASE IN CONVECTION IS LIKELY TO BE TEMPORARY AS STRONG UPPER-LEVEL WINDS CONTINUE TO SHOVE THE THUNDERSTORM ACTIVITY RAPIDLY AWAY FROM THE CENTER. DVORAK T- AND CI-NUMBERS FROM TAFB AND A RECENT ASCAT PASS SUGGEST THAT THE MAXIMUM WINDS REMAIN AROUND 25 KT. THE STRONG WESTERLY UPPER-LEVEL WINDS ARE FORECAST TO INCREASE FURTHER DURING THE NEXT COUPLE OF DAYS AND THIS SHOULD RESULT IN A FAIRLY QUICK DEMISE OF ROSA. THE SYSTEM IS EXPECTED TO BECOME A REMNANT LOW LATER TODAY AND DISSIPATE WITHIN 2 TO 3 DAYS. ROSA APPEARS TO HAVE DRIFTED EASTWARD DURING THE PAST FEW HOURS. THE TRACK GUIDANCE INDICATES THAT THE CYCLONE SHOULD RESUME A SLOW WEST-NORTHWESTWARD TO WESTWARD MOTION TODAY...AND THIS GENERAL MOTION SHOULD CONTINUE UNTIL DISSIPATION. THE NHC TRACK HAS BEEN ADJUSTED SLIGHTLY EAST OF THE PREVIOUS ADVISORY DURING THE FIRST 24 HOURS DUE TO THE MORE EASTWARD INITIAL POSITION. THE UPDATED TRACK IS IN GOOD AGREEMENT WITH THE MORE SOUTHERN SOLUTION OF THE ECMWF MODEL.
