SUBTROPICAL DEPRESSION ANDREA DISCUSSION NUMBER   7
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL012007
1100 PM EDT THU MAY 10 2007
 
EVEN THOUGH A FEW INTERMITTENT SHOWERS AND THUNDERSTORMS ARE
OCCURRING OVER THE EASTERN SEMICIRCLE...THIS ACTIVITY IS 
DISORGANIZED AND WEAK.  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.
