| #9772 (Received by flhurricane at: 4:59 PM 23.Sep.2004) TCDAT3 TROPICAL DEPRESSION LISA DISCUSSION NUMBER 18 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 PM EDT THU SEP 23 2004 VISIBLE SATELLITE IMAGERY SHOWS THAT NORTHERLY SHEAR HAS BLOWN AWAY THE DEEP CONVECTION AND EXPOSED A LOW LEVEL CLOUD CENTER TO THE NORTHEAST OF WHERE A CENTER LOCATION WAS ESTIMATED ON THE PREVIOUS ADVISORY. THIS REQUIRES A RELOCATION OF THE CENTER AND IMPLIES THAT THE CENTER HAS MOVED IN A CYCLONIC OOP OVER THE PAST 24 HOURS AND IS NOW MOVING ABOUT 300/05. THE GLOBAL TRACK MODELS ARE IN GOOD AGREEMENT ABOUT A SLOW MOSTLY NORTH-NORTHWESTWARD MOTION TOWARD A WEAKNESS IN THE SUBTROPICAL RIDGE TO THE NORTH OF LISA. THE OFFICIAL TRACK FORECAST FOLLOWS A CONSENSUS OF THE GUIDANCE AND IS ADJUSTED TO THE RIGHT OF THE PREVIOUS ADVISORY DUE TO THE RELOCATION. THE ABSENCE OF ANY DEEP CONVECTION NEAR THE CENTER IS GROUNDS FOR DOWNGRADING LISA TO A TROPICAL DEPRESSION. THE SHIPS MODEL INDICATES THAT THE VERTICAL SHEAR WILL WEAKEN SOME OVER THE NEXT 72 HOURS AND THE OFFICIAL FORECAST IS FOR MODEST INTENSIFICATION THROUGH 72 HOURS...A LITTLE MORE THAN SHIPS BUT NOT NEARLY AS AGGRESSIVE AS THE GFDL MODEL.
