TROPICAL CYCLONE (TC) 02S (TWO) LOCATED APPROXIMATELY 185 NM NORTH- NORTHEAST OF COCOS ISLAND, HAS TRACKED EAST-SOUTHEASTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED METSAT IMAGERY AND A 181511Z AMSU-B IMAGE DEPICT A WELL-CONSOLIDATED LOW LEVEL CIRCULATION CENTER (LLCC) WITH IMPROVING DEEP CONVECTION WRAPPING INTO THE WEST AND SOUTH SIDES OF THE CIRCULATION. ALTHOUGH CONVECTION HAS WANED SLIGHTLY OVER THE PAST 12 HOURS, RECENT IMAGERY SHOWS A RESURGENCE IN CONVECTIVE ACTIVITY WITH BANDING BECOMING TIGHTER AND BETTER DEFINED. THE LLCC LIES BENEATH A WEAKLY DEVELOPING UPPER-LEVEL ANTICYCLONE IN AN AREA OF MODERATE EASTERLY VERTICAL WIND SHEAR. THIS COUPLED WITH RELATIVELY WEAK OCEAN HEAT CONTENT VALUES MAY SERVE TO LIMIT THE MAXIMUM INTENS- ITY OF THE SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS ARE BASED UPON DVORAK ESTIMATES RANGING FROM 30 TO 35 KNOTS FROM KNES AND PGTW RES- PECTIVELY, AND A 180230Z ASCAT PASS DEPICTING 30 TO 40 WINDS NEAR THE CENTER. THE SYSTEM IS EXPECTED TO TRACK EAST-SOUTHEASTWARD OVER THE NEXT 48 HOURS UNDER THE INFLUENCE OF LOW- TO MID-LEVEL WESTERLY FLOW EQUATORWARD OF THE SYSTEM.

TROPICAL CYCLONE (TC) 02S (ANIKA), LOCATED APPROXIMATELY 705 NM WEST- NORTHWEST OF LEARMONTH HAS TRACKED SOUTHEASTWARD AT 15 KNOTS OVER THE PAST 06 HOURS. THE CURRENT POSITION IS BASED ON POSITION FIXES FROM PGTW AND APRF, AND A 201143Z 37 GHZ SSMIS MICROWAVE IMAGE. THE INITIAL INTENSITY REFLECTS SATELLITE INTENSITY ESTIMATES FROM PGTW AND APRF INDICATING A 35 TO 55 KNOT SYSTEM. VERTICAL WIND SHEAR HAS INCREASED IN EXCESS OF 30 KNOTS AS AN UPPER LEVEL TROUGH ENCROACHES ON THE CYCLONE FROM THE SOUTHWEST, SHEARING CONVECTION TO SOUTHEAST. CLOUD TOPS HAVE ALSO BEGUN TO WARM IN RESPONSE TO COOL SEA SURFACE TEMPERATURES. THE SYSTEM WILL CONTINUE TO TRACK GENERALLY SOUTHEAST- WARD FOR THE FIRST 36 HOURS, THEN LEVEL OFF TOWARDS THE EAST AS THE SYSTEM WEAKENS. CONTINUED MODERATE TO HIGH VERTICAL WIND SHEAR AND COOL SEA SURFACE TEMPERATURES WILL FURTHER WEAKEN THE CYCLONE THROUGH- OUT THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201200Z IS 11 FEET. NEXT WARNINGS AT 202100Z, 210300Z, 210900Z AND 211500Z.

TROPICAL CYCLONE (TC) 02S (ANIKA), LOCATED APPROXIMATELY 650 NM NORTHWEST OF LEARMONTH HAS TRACKED SOUTHEASTWARD AT 13 KNOTS OVER THE PAST 06 HOURS. RECENT MULTISPECTRAL AND INFRARED IMAGERY HAS INDI- CATED THAT THE LOW LEVEL CIRCULATION CENTER (LLCC) HAS BECOME SHEARED FROM THE CONVECTION. THE LLCC WILL CONTINUE TO TRACK EAST- SOUTHEAST WHILE THE CONVECTION WILL MOVE SOUTHEAST. TC 02S HAS MOVED POLEWARD OF THE NEAR EQUATORIAL RIDGING AND HAS CONTINUED TO SEE INCREASED VERTICAL WIND SHEAR OVER THE LLCC. IN ASSOCIATION WITH THE DECREASING SST'S A SIGNIFICANT DECREASE IN INTENSITY OVER THE PAST 06 HOURS HAS OCCURRED. THE LIKELIHOOD OF REDEVELOPMENT IS LOW AS THE ENVIRONMENT WILL REMAIN UNFAVORABLE UNTIL LANDFALL. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVMARFCSTCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201800Z IS 8 FEET. REFER TO TROPICAL CYCLONE 03S (BERNARD) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//
