ESSENTIALLY...ANDREA HAS BEEN VOID OF SIGNIFICANT DEEP CONVECTION FOR ALMOST 18 HOURS. THEREFORE THE SYSTEM NO LONGER MEETS THE CRITERIA TO BE CLASSIFIED AS A SUBTROPICAL CYCLONE...AND ADVISORIES ARE BEING TERMINATED. THE INITIAL INTENSITY IS HELD AT 30 KT BASED ON NEARBY SHIP WJBJ. ANDREA CONTINUES TO MOVE SOUTHWARD WITH AN INITIAL MOTION ESTIMATE OF 180/3. LACKING APPRECIABLE DEEP CONVECTION...THE REMNANT LOW SHOULD GRADUALLY SPIN DOWN OVER THE NEXT COUPLE OF DAYS. THE REMNANT OF ANDREA IS EXPECTED TO GRADUALLY LOOP CYCLONICALLY TO THE NORTHEAST OVER THE NEXT 48 HOURS. ALTHOUGH THE OFFICIAL FORECAST INDICATES DISSIPATION IN 72 HOURS...THE REMNANT LOW COULD HOLD TOGETHER LONG ENOUGH TO INTERACT WITH A DEVELOPING BAROCLINIC CYCLONE OFF THE U.S. EAST COAST.
