1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. AMEMBASSY SUVA REQ PASS TO USAID OFDA ADVISOR
3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
090 NM EITHER SIDE OF A LINE FROM 9.1S0 75.3E5 TO 12.2S5 71.8E6
WITHIN THE NEXT 12 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
170530Z6 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 9.2S1
75.2E4. THE SYSTEM IS MOVING SOUTHWESTWARD AT 10 KNOTS.
4. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.0S7 75.8E0 IS NOW
LOCATED NEAR 9.2S1 75.2E4, ABOUT 200 NM ESE OF DIEGO GARCIA.
ANIMATED VISIBLE SATELLITE IMAGERY INDICATES INCREASING ORGANIZATION
OF A FAIRLY WELL DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). RECENT
170309Z0 SSMI PASS ALONG WITH 170328Z1 PARTIAL TRMM PASS BOTH
INDICATE INCREASING CONSOLIDATION OF CONVECTION NEAR THE LLCC WITH
DEVELOPING BANDING IN THE NORTHWEST SEMICIRCLE OF THE CIRCULATION.
200 MB ANALYSIS INDICATES CONVECTION CURRENTLY IN A REGION OF WEAK
TO MODERATE VERTICAL WIND SHEAR AND MOVING INTO AN AREA OF STRONG
DIFFLUENT FLOW ALOFT AND A LOW VERTICAL WIND SHEAR ENVIRONMENT. THE
POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS NOW GOOD.
5. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
180630Z8.//

REMARKS:
172100Z1 POSITION NEAR 11.8S0 72.0E9.
TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 230 NM SOUTH
OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 14 KNOTS DURING THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 171730Z9 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 35 TO 55 KNOTS. RECENT SPECIAL SENSOR
MICROWAVE IMAGERY (SSM/I) INDICATES A DEVELOPING EYEWALL. THE SYSTEM
IS EXPECTED TO TRACK SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF
THE LOW TO MID-LEVEL SUBTROPICAL RIDGE TO THE SOUTH. AN APPROACHING
MID-LATITUDE TROUGH IS EXPECTED TO CREATE A WEAKNESS IN THE MID-
LATITUDE RIDGE SOUTH OF THE SYSTEM THAT SHOULD CAUSE THE TRACK TO
TURN MORE POLEWARD AFTER 48 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 171800Z7 IS 14 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,

REMARKS:
TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 410 NM
SOUTH-SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 18
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON

INTENSITY IS BASED ON SATELLITE INTENSITY ESTIMATES OF 65 KNOTS.
RECENT SPECIAL SENSOR MICROWAVE IMAGERY (SSM/I) INDICATED A
DEVELOPING EYEWALL WITH 180716Z3 METSAT-5 VISIBLE IMAGERY NOW
SHOWING A VERY WELL DEFINED 17 NM DIAMETER EYE. THE SYSTEM IS
EXPECTED TO TRACK SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF THE
LOW TO MID-LEVEL SUBTROPICAL RIDGE TO THE SOUTH THROUGH THE NEXT 24
HOURS. AN APPROACHING MID-LATITUDE TROUGH IS EXPECTED TO CREATE A
WEAKNESS IN THE MID-LATITUDE RIDGE AND CAUSE THE SYSTEM TO SLOW DOWN
AS STEERING FLOW TO THE SOUTH WEAKENS BY 48 HOURS. 180900Z8 POSITION

REMARKS:
200900Z1 POSITION NEAR 18.1S0 63.8E7.
TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 110 NM
NORTH-NORTHEAST OF RODRIGUES ISLAND, HAS TRACKED WEST-SOUTHWESTWARD
AT 09 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED
ON 200530Z0 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE INTENSITY ESTIMATES OF 127 TO 140 KNOTS. IMAGERY
ANALYSIS INDICATES A SIGNIFICANT COOLING TREND OF THE TOPS OF THE
CONVECTIVE RING, AS WELL AS THE EMERGENCE OF A DISTINCT (APPROX) 19
NM EYE. THEREFORE, WE BUMPED UP THE INTENSITY TO 130 KNOTS. A
BUILDING MID-LEVEL RIDGE EXTENDING SOUTHEASTWARD FROM THE SOUTHERN
TIP OF MADAGASCAR TO (APPROX) 30.0S3 60.0E6 SHOULD INFLUENCE A
GENERALLY WESTWARD TRACK THROUGH THE FORECAST PERIOD. OUR FORECAST
IS BASED ON A BLEND OF AVAILABLE NWP (NOGAPS, AVN, GFDN, UKMET
SPECTRAL) AND THE DEEP LAYER BETA ADVECTION MODEL BASED ON THE
200000Z2 NOGAPS RUN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 200600Z8 IS
26 FEET. NEXT WARNINGS AT 202100Z5 AND 210900Z2.//

TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 300 NM
EAST-NORTHEAST OF PORT LOUIS, HAS TRACKED WEST-SOUTHWESTWARD
AT 07 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED
ON 201730Z3 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE INTENSITY ESTIMATES OF 127 TO 140 KNOTS. IMAGERY
ANALYSIS INDICATES A WARMING TREND OF CLOUD TOPS DURING THE PAST 12
HOURS. THE MID-LEVEL RIDGE EXTENDING SOUTHEASTWARD FROM THE SOUTHERN

THROUGH THE FORECAST PERIOD. THE PASSAGE OF A MINOR SHORTWAVE TROUGH
LATE IN THE FORECAST IS EXPECTED TO SLOW AND TURN THE SYSTEM MORE
POLEWARD AT THE END OF THE FORECAST PERIOD. OUR FORECAST IS BASED ON
A BLEND OF AVAILABLE NWP (NOGAPS, AVN, GFDN, UKMET SPECTRAL) AND

REMARKS:
210900Z2 POSITION NEAR 19.0S0 60.0E6.
TROPICAL CYCLONE (TC) 10S (DINA), LOCATED APPROXIMATELY 185 NM
EAST-NORTHEAST OF PORT LOUIS, HAS TRACKED WESTWARD AT 10 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 210530Z1
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE INTENSITY ESTIMATES OF 115 AND 127 KNOTS. A 210505Z3 SSM/I
PASS DEPICTED AN OUTER CONVECTIVE RING DEVELOPING AROUND THE
EXISTING INNER EYEWALL. CURRENT VISIBLE IMAGERY REVEALS EXPANSION OF
THE EYE FEATURE. A CONCENTRIC EYEWALL EVENT MAY BE IN THE MAKING,
WHICH WOULD CAUSE A TEMPORARY INTENSIFICATION PERIOD. THE
SUBTROPICAL MID-LEVEL RIDGE EXTENDING EAST-SOUTHEASTWARD FROM THE
SOUTHERN TIP OF MADAGASCAR SHOULD INFLUENCE A GENERALLY WEST-
SOUTHWESTWARD TRACK THROUGH THE PERIOD. OUR FORECAST IS BASED ON A

KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
221730Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE INTENSITY ESTIMATES OF 115 AND 127 KNOTS. A 38 NM EYE
DIAMETER, SLIGHTLY ELONGATED, IS NOTED IN THE LATEST SATELLITE
IMAGERY. TC 10S (DINA) WILL BEGIN TRACKING SOUTHWEST UNDER THE
STEERING INFLUENCE OF A MID-LEVEL RIDGE SITUATED TO THE SOUTHEAST.
AN APPROACHING TROUGH, LATE IN THE FORECAST PERIOD, WILL STEER THE
SYSTEM POLEWARD. OUR FORECAST IS BASED ON A BLEND OF PERSISTENCE AND
AVAILABLE DYNAMIC AIDS (NOGAPS, AVN, GFDN, UKMET) WHICH ARE IN GOOD
AGREEMENT ON A CONTINUED TRACK SOUTHWEST AND THEN SOUTHWARD. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 221800Z3 IS 40 FEET. NEXT WARNINGS AT
230900Z4 AND 232100Z8.//

TROPICAL CYCLONE (TC) 10S (DINA), LOCATED SOUTHEAST OF MADAGASCAR,
HAS TRACKED SOUTH-SOUTHEASTWARD AT 15 KNOTS DURING THE PAST 6 HOURS.
THE WARNING POSITION IS BASED ON 241730Z7 INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 55 KNOTS. ANIMATION DEPICTS THAT TC 10S
(DINA) NEARING THE FINAL STAGES OF EXTRATROPICAL TRANSITION. TC 10S
IS FORECAST TO TURN INCREASINGLY SOUTHEASTWARD AND ACCELERATE AS IT
INTERACTS WITH A MID-LATITUDE BAROCLINIC SYSTEM. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 241800Z5 IS 26 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.
