 TROPICAL DEPRESSION LISA DISCUSSION NUMBER  24
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL142010
 1100 AM AST SUN SEP 26 2010
  
 LISA HAS LOST NEARLY ALL OF ITS DEEP CONVECTION AND NOW CONSISTS
 PRIMARILY OF A TIGHT SWIRL OF LOW-LEVEL CLOUDS.  AN 1104 UTC ASCAT
 OVERPASS CAPTURED THE EASTERN PORTION OF THE CIRCULATION AND SHOWED
 A SMALL AREA OF 25 TO 30 KT WINDS.  BASED ON THIS DATA AND
 SATELLITE INTENSITY ESTIMATES...THE INITIAL INTENSITY IS HELD AT 30
 KT FOR THIS ADVISORY.  THE COMBINATION OF CONTINUED STRONG
 SOUTHWESTERLY SHEAR...SEA SURFACE TEMPERATURES OF AROUND 25 C...AND
 A STABLE ATMOSPHERE SHOULD PREVENT THE FORMATION OF SIGNIFICANT
 CONVECTION NEAR THE CENTER OF LISA...THEREFORE...DEGENERATION TO A
 REMNANT LOW IS FORECAST TO OCCUR WITHIN THE NEXT 12 HOURS.  THE
 REMNANT LOW WILL LIKELY PERSIST FOR A FEW DAYS. 
  
 THE DEPRESSION IS MOVING TOWARD THE NORTH-NORTHWEST AT 6 KT.
 LISA...OR ITS REMNANT LOW...IS EXPECTED TO CONTINUE MOVING
 NORTH-NORTHWESTWARD TO NORTHWARD FOR THE NEXT FEW DAYS STEERED
 BETWEEN A RIDGE OVER WESTERN AFRICA AND A TROUGH TO THE WEST OF THE
 CYCLONE OVER THE EASTERN ATLANTIC.  THE OFFICIAL TRACK FORECAST IS
 AGAIN NUDGED SLIGHTLY TO THE WEST...TRENDING TOWARD THE MULTI-MODEL
 CONSENSUS.
