THIS CONVECTION...HOWEVER...IS LOCATED OVER 100 N MI FROM THE LOW-LEVEL CENTER. IN FACT...DEEP CONVECTION HAS NOT BEEN WITHIN 100 N MI OF THE CENTER FOR ABOUT THE LAST 11 HOURS. THEREFORE...LISA NO LONGER QUALIFIES AS A TROPICAL CYCLONE AND THIS IS THE LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER. SOUTHWESTERLY SHEAR OF AT LEAST 30 KT IS EXPECTED TO CONTINUE FOR THE NEXT DAY OR SO. THIS...COUPLED WITH A STABLE ATMOSPHERE AND A RELATIVELY COOL OCEAN SHOULD PREVENT REGENERATION. THE INITIAL MOTION ESTIMATE IS 335/6. THE REMNANT LOW IS EXPECTED TO CONTINUE MOVING NORTH-NORTHWESTWARD TO NORTHWARD FOR THE NEXT FEW DAYS WITHIN THE LOW-LEVEL FLOW.
