    REMARKS:
    100900Z POSITION NEAR 22.3S 112.6E.
    10APR21. TROPICAL CYCLONE 27S (ODETTE), LOCATED APPROXIMATELY 86
    NM NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWARD AT 24
    KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
    IMAGERY (MSI) INDICATES TC ODETTE CONTINUES TO SPIRAL INWARDS
    TOWARDS TC 26S AS PART OF FUJIWHARA INTERACTION. THE SYSTEM HAS
    RAPIDLY WEAKENED, THOUGH THERE HAS BEEN A FLARE UP IN DEEP
    CONVECTION NEAR THE CENTER IN THE PAST FEW HOURS, LIKELY A RESULT OF CONVERGENCE FLOW WITH THE OUTER BANDS OF TC 26S. THE INITIAL
    POSITION IS PLACED WITH MODERATE CONFIDENCE BASED ON A MANUAL TRACK
    OF THE LOW LEVEL VORTEX THROUGH THE ANIMATED VISIBLE IMAGERY. THE
    OVERALL SYSTEM INTENSITY HAS BEEN LOWERED TO 30 KNOTS BASED ON A
    PGTW DVORAK INTENSITY ESTIMATE OF T2.0 (30 KTS). AUTOMATED CIMSS ADT
    ESTIMATES ARE MUCH HIGHER BUT ARE CONSIDERED UNREALISTIC DUE TO
    FIXING ON THE TRANSIENT CONVECTIVE ACTIVITY. AN EARLIER 100012Z
    ASCAT-A PASS REVEALED A VERY SMALL AREA OF GALE FORCE WINDS IN THE
    EASTERN HEMISPHERE, BUT THESE ARE NOT CONSIDERED REPRESENTATIVE OF
    THE OVERALL INTENSITY, THOUGH NEAR-GALE FORCE WINDS COULD
    POTENTIALLY STILL BE PRESENT ON THE EASTERN SIDE OF THE CIRCULATION. ENVIRONMENTAL CONDITIONS ARE INCREASINGLY HOSTILE, WITH AN ESTIMATED
    15-20 KNOTS OF EASTERLY VERTICAL WIND SHEAR (VWS) AND A CONSTRAINED
    OUTFLOW REGIME WHICH IS INHIBITING THE SYSTEM. TC 27S WILL CONTINUE
    TO TRACK TOWARDS THE SOUTHWEST, SPIRALING CLOSER TO TC 26S WHILE
    FULLY DISSIPATING AS A DISTINCT CIRCULATION WITHIN THE NEXT 12
    HOURS. DYNAMIC MODEL GUIDANCE IS IN OVERALL GOOD AGREEMENT ON THE
    MERGER AND DISSIPATION SCENARIO, LENDING HIGH CONFIDENCE TO THE JTWC
    FORECAST TRACK. 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 100600Z IS 13 FEET. REFER TO TROPICAL CYCLONE 26S (SEROJA)
    WARNINGS (WTXS31 PGTW) FOR SIX-HOURLY UPDATES.//
