TROPICAL STORM FRANKLIN DISCUSSION NUMBER 19
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT MON JUL 25 2005 edited~danielw

FRANKLIN HAS UNDERGONE ANOTHER STRUCTURAL CHANGE THIS EVENING. A NEW VORTICITY CENTER APPEARED FROM UNDER THE CONVECTION EAST OF THE
MAIN CIRCULATION CENTER...AND IT AND THE MAIN CENTER ARE ROTATING AROUND EACH OTHER. THE CENTER TRACKED EARLIER IS CURRENTLY THE MOST INVOLVED WITH CONVECTION...SO THAT CENTER POSITION IS USED IN
THIS ADVISORY.
HOWEVER...THE APPEARANCE OF THE SECONDARY VORTICITY CENTER SUGGESTS THE POSSIBILITY THAT THE OVERALL SYSTEM MAY REFORM
DURING THE NEXT DAY OR SO...OR THAT A MEAN CIRCULATION CENTER MAY BECOME MORE APPROPRIATE FOR TRACKING. THE INITIAL INTENSITY REMAINS 35 KT BASED ON SATELLITE ESTIMATES OF 35 KT FROM TAFB AND AFWA...AND 30 KT FROM SAB.
