300300Z POSITION NEAR 13.5S 122.0E. TROPICAL CYCLONE 17S (FRANCES), LOCATED APPROXIMATELY 270 NM NORTH OF BROOME, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER DEVOID OF ANY ASSOCIATED CONVECTION AND IS THE BASIS FOR THE INITIAL POSITION. THE INITIAL INTENSITY OF 35 KNOTS IS BASED ON THE RAPID WEAKENING TREND OBSERVED OVER THE LAST 24 HOURS HEDGING IN THE LOWER ENVELOPE OF CURRENT INTENSITY DVORAK ESTIMATES RANGING FROM T2.5- T3.0 (35 TO 45 KNOTS). ENVIRONMENTAL CONDITIONS HAVE DETERIORATED SIGNIFICANTLY IN THE UPPER LEVELS AS THE WESTERLY JET APPROACHES INTRODUCING HIGH VERTICAL WIND SHEAR, AND WILL PERSIST FOR THE NEXT FEW DAYS LIMITING THE POSSIBILITY OF INTENSIFICATION. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 300000Z IS 12 FEET.
