REMARKS:
032100Z6 POSITION NEAR 10.5S6 61.9E6.
TROPICAL CYCLONE (TC) 18S HAS TRACKED SOUTHWEST AT 4 KTS IN THE PAST
6 HOURS AND IS APPROXIMATELY 640 NM NORTH-NORTHEAST OF MAURITIUS.
THE WARNING POSITION IS BASED UPON ANIMATED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED UPON CURRENT INTENSITY
ESTIMATES OF 30 AND 35 KNOTS. 24 HOUR ANALYSIS OF QUIKSCAT DATA
CLEARLY INDICATES A COMPACTING LOW-LEVEL CIRCULATION CENTER (LLCC)
ASSOCIATED WITH THIS AREA. ANIMATED SATELLITE IMAGERY REVEALS
DEEPENING CONVECTION OVER THE LLCC. TC 18S IS EXPECTED TO DRIFT IN A
SOUTHWESTERLY DIRECTION THROUGH THE FORECAST PERIOD. TC 18S IS
EXPECTED TO INTENSIFY SLOWLY DURING THE FORECAST PERIOD AS THE
SYSTEM CONTINUES TO CONSOLIDATE AND DRIFT INTO A MORE FAVORABLE
UPPER-LEVEL ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031800Z2
IS 12 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,
NAVPACMETOCCEN 022121Z APR 01 TROPICAL CYCLONE FORMATION ALERT
(WTXS24 PGTW 022130). NEXT WARNINGS AT 040900Z3 AND 042100Z7.

TROPICAL CYCLONE (TC) 18S HAS TRACKED SOUTHEAST AT 12 KTS IN THE
PAST 6 HOURS AND IS APPROXIMATELY 450 NM NORTH OF RODRIGUES ISLAND.
THE WARNING POSITION IS BASED UPON 040530Z2 VISIBLE AND INFRARED

TROPICAL CYCLONE (TC) 18S (EVARISTE), LOCATED APPROXIMATELY 290 NM
SOUTH OF RODRIGUES ISLAND, HAS TRACKED SOUTHEAST AT 18 KTS DURING
THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 080530Z6
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON
CURRENT INTENSITY ESTIMATES OF 25 AND 35 KNOTS. ANIMATED SATELLITE
IMAGERY INDICATES THE LOW-LEVEL CIRCULATION ASSOCIATED WITH TC 18S
REMAINS FULLY EXPOSED AND IS MOVING TO THE SOUTHEAST. ANIMATED WATER
VAPOR IMAGERY SHOWS A LONG WAVE FEATURE TO THE WEST THAT IS EXPECTED
TO SUPPORT THE DEVELOPMENT OF A MID-LAT LOW WITH THE REMNANTS OF TC
18S. THIS SYSTEM IS FORECAST TO TRACK SOUTHEASTWARD AS IT RE-
INTENSIFIES AS A BAROCLINIC SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 080600Z4 IS 18 FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM BY
THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL
BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. REFER TO TROPICAL
CYCLONE 17S (WALTER) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY
