REMARKS:
182100Z2 POSITION NEAR 25.7S4 160.7W4.
TROPICAL CYCLONE (TC) 19P (OLAF), LOCATED APPROXIMATELY 205 NM
SOUTH-SOUTHWEST OF RAROTONGA, HAS TRACKED SOUTH-SOUTHEASTWARD AT
21 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
181730Z0 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 77, 90 AND 115
KNOTS FROM ALL AGENCIES. A RECENT 181743Z4 SSMI PASS AND ANIMATED
MULTISPECTRAL SATELLITE IMAGERY REVEALS THAT THE DEEP CONVECTION IS
BEING DISPLACED TO THE SOUTHEAST. THIS IMAGERY ALSO SHOWS COLD AIR
STRATOCUMULUS BEING WRAPPED IN FROM THE WEST. TC 19P IS CURRENTLY
TRACKING POLEWARD UNDER THE STEERING INFLUENCE OF A RIDGE TO THE
EAST. THE TRACK IS EXPECTED TO DEVIATE MORE  SOUTHWESTWARD AS THE
RIDGE BUILDS. TC 19P IS FORECASTED TO WEAKEN RAPIDLY AS IT
ENCOUNTERS INCREASING VERTICAL SHEAR AND UNFAVORABLE SEA SURFACE
TEMPERATURES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 181800Z IS 26 FEET.
NEXT WARNINGS AT 190900Z9 AND 192100Z3.//
