09 KNOTS. THE WARNING POSITION AND INTENSITY ARE BASED ON
EXTRAPOLATION OF 082140Z5 INFRARED SATELLITE IMAGERY. THIS
SYSTEM IS REPOSITIONED BASED ON REANALYSIS OF AVAILABLE

SATELLITE IMAGERY INDICATES THIS SYSTEM HAS WEAKENED SLIGHTLY
OVER THE PAST 06 HOURS. CLOUD TOP TEMPERATURES HAVE WARMED AND
UPPER-LEVEL OUTFLOW HAS BECOME SLIGHTLY LESS WELL ORGANIZED.
TROPICAL CYCLONE 26S (DONALINE) IS FORECAST TO MOVE ROUGHLY
SOUTHWARD THROUGHOUT THE FORECAST PERIOD UNDER THE STEERING
INFLUENCE OF A MID-LEVEL ANTICYCLONE TO ITS EAST. THIS SYSTEM
IS EXPECTED TO WEAKEN STEADILY THROUGHOUT THE FORECAST PERIOD
AS IT MOVES INTO A REGION OF MODERATE TO STRONG VERTICAL WIND
SHEAR OVER COLDER WATER. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
090000Z9 IS 14 FEET. NEXT WARNINGS AT 091500Z5 AND 100300Z4.//
