REMARKS:
040900Z3 POSITION NEAR 12.2S5 59.0E4.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
490 NM NORTH-NORTHEAST OF MAURITIUS, HAS TRACKED WESTWARD
AT 07 KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION
IS BASED ON 040530Z2 MULTISPECTRAL SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 65 KNOTS. A RECENT ADVANCED MICROWAVE SOUNDING
UNIT (AMSU) PASS AT 040616Z7 SHOWS THAT TC 16S HAS FORMED
A SMALL, SYMMETRICAL EYE. THE SYSTEM IS EXPECTED TO CONTINUE
TRACKING WESTWARD FOR THE NEXT 24 HOURS ALONG THE NORTHERN
PERIPHERY OF THE MID-LEVEL STEERING RIDGE LOCATED TO THE SOUTH
AND THEN BEGIN TO TURN POLEWARD TOWARDS A WEAKNESS IN THE RIDGE
ENHANCED BY THE APPROACH OF A MAJOR SHORTWAVE FROM THE SOUTHWEST.
TC 16S IS FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE IN
A FAVORABLE UPPER LEVEL ENVIRONMENT THROUGH THE ENTIRE FORECAST
PERIOD. AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, EGRR, GFDN,
AFWA, AND NCEP GFS ARE IN GOOD AGREEMENT WITH THIS SCENARIO. EGRR
DOES NOT WEAKEN THE RIDGE TO THE SOUTH AS FAST AS THE OTHER AIDS
RESULTING IN A MORE WESTWARD TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 040600Z0 IS 19 FEET. NEXT WARNINGS AT 042100Z7 AND 050900Z4.

REMARKS:
042100Z7 POSITION NEAR 13.3S7 57.6E8.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY 415 NM
NORTH OF MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
041730Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 77 and
90 KNOTS. THE SYSTEM IS EXPECTED TO CONTINUE TRACKING SOUTH-
WESTWARD FOR THE FORECAST PERIOD ALONG THE NORTHWESTERN
PERIPHERY OF THE MID-LEVEL STEERING RIDGE LOCATED TO THE SOUTH.
ALTHOUGH DRY AIR ENTRAINMENT HAS SIGNIFICANTLY REDUCED CONVECTION,
THE INTENSITY WILL CONTINUE TO INCREASE BEYOND CLIMATOLOGICAL
RATES THROUGH THE ENTIRE FORECAST PERIOD DUE TO EXCELLENT POLAR,
CROSS EQUATORIAL, AND WESTWARD OUTFLOW IN A FAVORABLE UPPER LEVEL
ENVIRONMENT. AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, EGRR,
GFDN, AND NCEP GFS ARE IN GOOD AGREEMENT WITH THIS SCENARIO.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z3 IS 24 FEET.
NEXT WARNINGS AT 050900Z4 AND 052100Z8.//

052100Z8 POSITION NEAR 14.5S0 054.8E7.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
370 NM NORTH OF MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION
IS BASED ON 051730Z6 ENHANCED INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 115 AND 127 KNOTS. RECENT MICROWAVE SATELLITE
IMAGERY DEPICTS A DISTINCT 15 NM DIAMETER EYE. TC 16S IS
EXPECTED TO CONTINUE TRACKING SOUTHWESTWARD OVER THE FORECAST
PERIOD AS IT TRACKS ALONG THE NORTHWESTERN PERIPHERY OF
THE MID-LEVEL STEERING RIDGE LOCATED TO THE SOUTHEAST OF
THE SYSTEM. IMPROVED DUEL OUTFLOW CHANNELS HAVE CONTRIBUTED
TO AN INTENSIFICATION RATE THAT HAS BEEN ABOVE CLIMATOLOGY
OVER THE PAST 24 HOURS. TC 16S IS FORECAST TO CONTINUE TO
INTENSIFY AT A SLIGHTLY LESS THAN CLIMATOLOGICAL RATE IN
A FAVORABLE UPPER LEVEL ENVIRONMENT OVER THE NEXT 12 TO
24 HOURS. BEYOND TAU 24 TC 16S IS FORECAST TO WEAKEN
SLOWLY DUE TO DECREASED POLEWARD OUTFLOW ALOFT AND
INTERACTION WITH LAND. THE AVAILABLE DYNAMIC AIDS CONSISTING
OF NOGAPS, EGRR, GFDN AND NCEP GFS ARE IN FAIR AGREEMENT
WITH THIS SCENARIO. THE DYNAMIC AIDS INDICATE MODERATE
DISAGREEMENT IN THE TIMING OF RECURVATURE OF THE SYSTEM
OVER MADAGASCAR, WITH NOGAPS AND NCEP GFS TURNING TC 16S
POLEWARD EARLIER THAN EGRR. THIS FORECAST IS BASED ON A
CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 051800Z4 IS 30 FEET. NEXT WARNINGS AT 060900Z5

TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
410 NM NORTHWEST OF MAURITIUS, HAS TRACKED WESTWARD AT 09
KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED
ON 060530Z4 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 140 KNOTS. A RECENT SSM/I IMAGE DEPICTS A DISTINCT 20 NM
EYE. TC 16S IS EXPECTED TO TRACK SOUTHWESTWARD OVER THE
FORECAST PERIOD ALONG THE NORTHWESTERN PERIPHERY OF THE MID
LEVEL STEERING RIDGE LOCATED SOUTHEAST OF THE SYSTEM. INTENSITY
FOR TC 16S IS EXPECTED TO PEAK WITHIN THE NEXT 12 HOURS AND
THEN BEGIN WEAKENING DUE TO DECREASED POLEWARD OUTFLOW AND
INTERACTION WITH LAND. THE AVAILABLE DYNAMIC AIDS CONSISTING
OF NOGAPS, EGRR, GFDN, AFWA MM5 AND NCEP GFS ARE IN FAIR
AGREEMENT. GFDN AND NCEP GFS DEPICT A WEAKER STEERING RIDGE
AND THEREFORE TURN TC 16S POLEWARD EARLIER. THIS FORECAST IS
BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS WITH MORE
EMPHASIS ON THE EGRR/NOGAPS SOLUTION DUE TO BETTER VERIFICATION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 060600Z2 IS 33 FEET. NEXT

072100Z0 POSITION NEAR 16.5S2 046.3E3.
TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY
170 NM NORTH OF ANTANANARIVO, MADAGASCAR HAS TRACKED
WEST-SOUTHWESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 071730Z8 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 77 AND 90 KNOTS. RECENT
SATELLITE IMAGERY INDICATES WEAKENING OF TC 16S AS IT CONTINUES
TO INTERACT WITH LAND. TC 16S IS EXPECTED TO CONTINUE TO TRACK
SOUTHWESTWARD THROUGH TAU 12 ALONG THE NORTHWESTERN PERIPHERY
OF THE MID LEVEL STEERING RIDGE LOCATED TO THE SOUTHEAST. AN
APPROACHING MID-LATITUDE TROUGH HAS WEAKENED THE RIDGE TO THE
SOUTH OF TC 16S. TC 16S IS FORECAST TO TRANSITION TO A MORE
POLEWARD TRACK FOR THE REMAINDER OF THE FORECAST PERIOD. THE
INTENSITY OF TC 16S IS EXPECTED TO CONTINUE TO SLOWLY WEAKEN
DUE TO INTERACTION WITH LAND. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, EGRR, GFDN, AFWA MM5 AND NCEP GFS ARE
IN FAIR AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF
THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 071800Z6 IS 24 FEET. NEXT WARNINGS AT 080900Z7 AND

TROPICAL CYCLONE (TC) 16S (GAFILO), LOCATED APPROXIMATELY 235 NM
WEST-SOUTHWEST OF ANTANANARIVO, MADAGASCAR HAS TRACKED
SOUTHEASTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 091730Z0 ENHANCED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 55 AND 65 KNOTS. TC 16S IS FORECASTED
TO TRACK SOUTHEASTWARD ALONG THE WESTERN PERIPHERY OF THE LOW TO
MID-LEVEL STEERING RIDGE LOCATED TO THE EAST. THE SYSTEM IS
FORECAST TO WEAKEN AS IT INTERACTS WITH THE SOUTHWEST COAST OF
MADAGASCAR. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS,
GFDN, AFWA MM5, WBAR, AND NCEP GFS ARE IN POOR AGREEMENT.
UKMET EGRR DEVELOPS A RIDGE OVER MOZAMBIQUE, TURNING THE SYSTEM
EQUATORWARD AFTER 12 TO 24 HOURS. THE OTHER MODELS WEAKEN THE SYSTEM
AS IT TRACKS OVER MADAGASCAR, BUT VARY IN SPEED. THIS FORECAST IS
BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS, WITH LESS EMPHASIS
ON EGRR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z8 IS 16 FEET.
