1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
180 NM EITHER SIDE OF A LINE FROM 10.0S1 66.7E9 TO 13.2S6 62.2E0
WITHIN THE NEXT 06 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 051130Z0 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 10.7S8 65.7E8. THE SYSTEM IS MOVING WEST-
SOUTHWESTWARD AT 03 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.3S4
66.5E7, IS NOW LOCATED NEAR 10.7S8 65.7E8, APPROXIMATELY 450 NM
WEST-SOUTHWEST OF DIEGO GARCIA. A RECENT QUICKSCAT PASS INDICATES A
BROAD LOW LEVEL CIRCULATION CENTER (LLCC), WHILE ANIMATED SATELLITE
IMAGERY DEPICTS INCREASED ORGANIZATION OF THE DEEP CONVECTION NEAR
THE LLCC. A 051414Z5 SPECIAL SENSOR MICROWAVE IMAGE (SSMI) PASS ALSO
REVEALS IMPROVED SYSTEM ORGANIZATION. 200MB ANALYSIS SHOWS THE AREA
IS UNDER WEAK DIFFLUENT FLOW ALOFT. MAXIMUM SUSTAINED WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1005 MB. THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS NOW GOOD.

REMARKS:
070300Z0 POSITION NEAR 11.8S0 58.9E2.
TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 510 NM
NORTH-NORTHEAST OF PORT LOUIS IN THE SOUTH INDIAN OCEAN HAS TRACKED
WEST-SOUTHWESTWARD AT 13 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 062300Z1 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 55 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY REVEALS CONTINUED
WRAPPING DEEP CONVECTION ENCOMPASSING A WELL-DEFINED LOW LEVEL
CIRCULATION CENTER (LLCC). 200MB ANALYSIS INDICATES THE SYSTEM IS
NEAR THE RIDGE AXIS IN A REGION OF FAVORABLE VERTICAL WIND SHEAR.
TC 18S WILL TRACK TO THE WEST-SOUTHWEST THROUGH THE NEXT 48 HOURS
GUIDED BY THE LOW TO MID-LEVEL RIDGE TO THE SOUTH. AFTER THIS TIME
AN APPROACHING TROUGH WILL WEAKEN THE RIDGE ENABLING A MORE POLEWARD
TRACK TO THE SOUTH-SOUTHWEST THROUGH 72 HOURS. THE AVAILABLE DYNAMIC
AIDS CONSISTING OF GFDN, AVN, NOGAPS AND UK MET GLOBAL ARE IN GOOD
AGREEMENT. TC 18S IS FORECAST TO CONTINUE TO INTENSIFY AT A
CLIMATOLOGICAL RATE AS THE SYSTEM TRACKS NEAR THE SUB-TROPICAL RIDGE
AXIS AND WARM SEA SURFACE TEMPERATURES. THE FORECAST TRACK IS BASED

TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 250 NM
EAST OF CAPE AMBRE, MADAGASCAR, HAS TRACKED WESTWARD AT 08 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 081130Z3
VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 115 KNOTS.
ANIMATED INFRARED SATELLITE IMAGERY INDICATES INCREASING COVERAGE OF
DEEP CONVECTION IN ALL QUADRANTS. THE 200 MB ANALYSIS INDICATES THAT
UPPER LEVELS REMAIN FAVORABLE FOR FURTHER DEVELOPMENT. TC 18S IS
SITUATED ON THE WESTERN EXTENSION OF A MID-LEVEL RIDGE AND IS
FORECAST TO TRACK WESTWARD DURING THE NEXT 12 TO 18 HOURS AND THEN
TURN SHARPLY POLEWARD AS A LONGWAVE TROUGH APPROACHES AND REORIENTS
THE STEERING FLOW. THE AVAILABLE DYNAMIC AIDS COMPRISE GFDN, AVN,
NOGAPS AND UK MET GLOBAL AND ARE IN GOOD AGREEMENT. TC 18S IS
FORECAST TO FURTHER INTENSIFY IN A FAVORABLE ENVIRONMENT FOR THE
NEXT 24 TO 36 HOURS. AFTERWARDS, THE SYSTEM IS EXPECTED TO ENCOUNTER
INCREASING WESTERLY VERTICAL SHEAR AND SLOWLY WEAKEN. THE FORECAST
TRACK IS BASED ON PERSISTENCE AND A BLEND OF THE AVAILABLE DYNAMIC

IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 127 KNOTS.
ANIMATED INFRARED SATELLITE IMAGERY DEPICTS A 24 NM EYE. TC 18S IS

FORECAST TO INCREASE ONCE THE POLEWARD TURN IS COMPLETE. TC 18S IS
FORECAST TO SLOWLY WEAKEN AS ITS WESTERN HALF INTERACTS WITH

111500Z8 POSITION NEAR 21.5S8 51.8E4.
TROPICAL CYCLONE (TC) 18S (HARY), LOCATED APPROXIMATELY 220 NM
WEST OF LA REUNION ISLAND, HAS TRACKED SOUTH-SOUTHEASTWARD AT 16
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
111130Z7 MULTI-SPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 AND 115 KNOTS.
A RECENT SPECIAL SENSOR MICROWAVE IMAGE (SSMI) PASS AND ANIMATED
MULTI-SPECTRAL SATELLITE IMAGERY REVEAL THAT TC 18S HAS AN EYE
FEATURE WITH A TIGHTLY WRAPPED CONVECTIVE BAND TO THE EAST. TC 18S
HAS TRACKED SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF A MID-
LEVEL RIDGE TO THE EAST AND A MID-LEVEL TROUGH TO THE WEST. THE
TROUGH TO THE WEST CONTINUES TO DEEPEN AND CREATE NORTHWESTERLY
VERTICAL WIND SHEAR. A SOUTHEASTWARD TRACK IS EXPECTED THROUGH THE
PERIOD AS SYNOPTIC SITUATION DOES NOT CHANGE. AS THE SYSTEM
CONTINUES TO MOVE OVER OPEN WATER, IT SHOULD MAINTAIN INTENSITY
THROUGH MID-PERIOD. THEREAFTER, SLOW WEAKENING IS EXPECTED AS THE
SYSTEM PASSES SOUTH OF THE UPPER LEVEL RIDGE AXIS. THE AVAILABLE
DYNAMIC AIDS CONSISTING OF GFDN, AVN, NOGAPS AND UK MET GLOBAL ARE
IN GOOD AGREEMENT WITH THIS SCENARIO. THE FORECAST TRACK IS BASED ON
PERSISTENCE AND A BLEND OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111200Z5 IS 30 FEET. NEXT WARNINGS AT
120300Z6 AND 121500Z9.//
