REMARKS:
180900Z8 POSITION NEAR 21.9S2 162.5W4.
TROPICAL CYCLONE (TC) 19P (OLAF), LOCATED APPROXIMATELY 175
NM WEST OF RAROTONGA, HAS TRACKED SOUTHEASTWARD AT 20 KNOTS
OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
180530Z7 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 115 KNOTS FROM ALL AGENCIES. ANIMATED SATELLITE IMAGERY
REVEALS A DECREASE IN CONVECTION IN THE SOUTHWESTERN QUADRANT.
RECENT ENHANCED INFRARED IMAGERY SHOWS THAT THE EYE IS WARM-
ING, AND BECOMING RAGGED AND CLOUD-FILLED. TC 19P IS CURRENTLY
TRACKING SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A RIDGE
TO THE EAST. AFTER TAU 12, THE TRACK WILL TURN SOUTHWARD
AND THEN SOUTHWESTWARD AS THE RIDGE ANCHORED TO THE SOUTH
BUILDS WESTWARD AND BEGINS TO PROVIDE THE DOMINANT STEERING
FLOW. TC 19P IS FORECAST TO WEAKEN AS IT ENCOUNTERS DRIER AIR
AND INCREASED VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 180600Z5 IS 28 FEET. NEXT WARNINGS AT 182100Z2 AND
190900Z9.//
