TROPICAL CYCLONE 04P (YOLANDE) LOCATED APPROXIMATELY 510 NM EAST-
SOUTHEAST OF FIJI. TC 04P HAS TRACKED EAST-SOUTHEASTWARD AT 12 KTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 050530Z3

WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 30 AND 35 KNOTS. WATER VAPOR IMAGERY AND MICROWAVE IMAGES
INDICATE THE SYSTEM HAS NEARLY COMPLETED EXTRATROPICAL TRANSITION
THROUGH CONTINUED INTERACTION WITH A BAROCLINIC ZONE TO THE
SOUTHWEST. THE LOW LEVEL CIRCULATION CENTER (LLCC) IS NOW FULLY
EXPOSED, WITH VERY LITTLE REMAINING DEEP CONVECTION ASSOCIATED WITH
THE LLCC. THE FORECAST TRACK IS BASED ON A BLEND OF ALL AVAILABLE
DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 050600Z1 IS 13
FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION.//
