REMARKS:
152100Z9 POSITION NEAR 20.8S0 158.4W8.
TROPICAL CYCLONE (TC) 18P (NANCY), LOCATED APPROXIMATELY
100 NM NORTHEAST OF RAROTONGA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 12 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS
BASED ON 151730Z7 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
77 AND 90 KNOTS. TC 18P IS FORECAST TO CONTINUE TO TRACK
POLEWARD THEN BEGIN TRACKING SOUTH-SOUTHEASTWARD AHEAD OF
A MAJOR SHORTWAVE TROUGH AFTER TAU 36. THE INTENSITY OF TC 18P
IS DECREASING AS IT ENCOUNTERS INCREASED VERTICAL WIND SHEAR
AND DRY AIR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151800Z5 IS
25 FEET. NEXT WARNINGS AT 160900Z6 AND 162100Z0. REFER TO
TROPICAL CYCLONE 19P (OLAF) WARNINGS (WTPS32 PHNC) FOR

REMARKS:
160300Z0 POSITION NEAR 12.5S8 171.9W8.
TROPICAL CYCLONE (TC) 19P (OLAF), LOCATED APPROXIMATELY 170
NM NORTHWEST OF PAGO PAGO, AMERICAN SAMOA, HAS TRACKED
EASTWARD AT 09 KNOTS OVER THE PAST 06 HOURS. THE WARNING
POSITION IS BASED ON 152330Z4 MULTISPECTRAL SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 140 AND 155 KNOTS. RECENT ANIMATED
WATER VAPOR IMAGERY DEPICTS SUSTAINED RADIAL OUFLOW AND
STRONG DEEP CONVECTION. TC 19P HAS TRACKED EASTWARD OF THE
FORECASTED TRACK OVER THE PAST 12 HOURS DUE TO INTERACTION
WITH AN UPPER LEVEL LOW CENTERED TO THE SOUTHEAST BETWEEN TC
19P AND TC 18P. TC 19P IS FORECAST TO CONTINUE TO TRACK
EASTWARD IN THE NEAR TERM AND TURN SOUTHEASTWARD ALONG THE
PERIPHERY OF A STEERING RIDGE SITUATED TO THE NORTHEAST. THE
SYSTEM IS EXPECTED TO CONTINUE TO INTENSIFY DURING THE NEXT
12 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 160000Z7 IS 50 FEET.
NEXT WARNINGS AT 161500Z3 AND 170300Z1. REFER TO TROPICAL CYCLONE
18P (NANCY) WARNINGS (WTPS31 PHNC) FOR TWELVE-HOURLY UPDATES.//
