REMARKS:
062100Z POSITION NEAR 23.3S 78.2E.
06FEB22. TROPICAL CYCLONE 10S (CLIFF), LOCATED APPROXIMATELY 1030
NM SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED SHORTWAVE INFRARED 
SATELLITE IMAGERY DEPICTS A FULLY EXPOSED LOW LEVEL CIRCULATION 
CENTER (LLCC), WHICH IS DEVOID OF ANY SIGNIFICANT CONVECTION. THE 
INITIAL POSITION IS ASSESSED WITH HIGH CONFIDENCE BASED ON A 061705Z 
MODIS TERRA INFRARED IMAGE, WHICH ELIMINATED THE LIMB ISSUES 
ASSOCIATED WITH THE METEOSAT-8 AND HIMWARI-8 IMAGERY. THE INITIAL 
INTENSITY IS SET WITH LOW CONFIDENCE AT A GENEROUS 35 KNOTS, IN LINE 
WITH EARLIER ASCAT DATA AND THE ADT ESTIMATE. THE SYSTEM IS TRACKING 
WEST-SOUTHWESTWARD ALONG THE NORTHERN SIDE OF A DEEP SUBTROPICAL 
RIDGE (STR) TO THE SOUTH. TC 10S IS STEADILY WEAKENING AS IT SPINS 
DOWN, HAVING BEEN OVERWHELMED BY DRY AIR AND STRONG VERTICAL WINDS 
SHEAR. THE SYSTEM IS EXPECTED TO WEAKEN TO 30 KNOTS WITHIN THE NEXT 
12 HOURS. THE REMNANT CIRCULATION IS EXPECTED TO CONTINUE TRACKING 
WESTWARD FOR SEVERAL DAYS AFTER DIPPING BELOW THE 35 KNOT WARNING 
THRESHOLD. 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 
061800Z IS 13 FEET. REFER TO TROPICAL CYCLONE 08S (BATSIRAI) 
WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//
