| #7440 (Received by flhurricane at: 4:32 PM 04.Sep.2004) TCDAT4 TROPICAL STORM IVAN DISCUSSION NUMBER 9 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 PM EDT SAT SEP 04 2004 SATELLITE IMAGES THIS AFTERNOON SHOW THAT IVAN HAS BECOME BETTER ORGANIZED. THERE IS A BAND OF DEEP CONVECTION THAT WRAPS PRACTICALLY ALL THE WAY AROUND THE SYSTEM CENTER...WHICH USING THE DVORAK TECHNIQUE GIVES A DATA T NUMBER OF 3.5 OR 55 KT FOR THE CURRENT INTENSITY. THE SHIPS GUIDANCE SUGGESTS THAT IVAN WILL REMAIN IN A WEAK SHEAR ENVIRONMENT OVER THE NEXT SEVERAL DAYS. SO...CONTINUED INTENSIFICATION IS LIKELY. A SWIFT...MOSTLY WESTWARD...MOTION CONTINUES. THERE ARE NO IMPORTANT CHANGES TO THE SYNOPTIC REASONING BEHIND THE TRACK FORECAST SINCE THE PREVIOUS ADVISORIES. A STRONG RIDGE IS EXPECTED TO PREVAIL TO THE NORTH OF THE TROPICAL CYCLONE. THEREFORE ONLY A GENTLE BEND TO THE NORTH IS FORECAST...WITHOUT MUCH DECREASE IN FORWARD SPEED UNTIL LATE IN THE PERIOD. BECAUSE OF THE TYPICAL TRACK FORECAST ERRORS AT 5 DAYS...THE CENTER COULD EASILY PASS SOUTH...OR NORTH...OF THE ISLAND OF HISPANIOLA.
