紀錄以來，史上登陸非洲最強的氣旋肯尼斯，已經登陸了莫三比克（強烈颱風等級）
氣旋肯尼斯登陸了莫三比克奎林巴斯國家公園、彭巴附近


目前造成有６人死亡。


















不過這次登陸人口較少，跟前一個氣旋伊代登陸地方距離也很遠。

T=CI=6.5+
OVER THE LAST SIX HOURS, CLOUD TOPS SURROUNDING KENNETH'S PINHOLE EYE
HAVE CONTINUED TO COOL, THUS INCREASING FURTHER THE INTENSITY
ESTIMATES. THE CURRENT INTENSITY ANALYSIS IS BASED ON A 3-HRS MEAN OF
THE LAST DVORAK ANALYSIS, BUT SOME IMAGES HAVE TEMPORARILY REACHED A
7.0 T-NUMBER. THE 0201Z AND 0105Z MW 89GHZ SSMIS IMAGES SHOW A VERY
COMPACT AND SOLID INNER-CORE. HOWEVER, AN OUTER BAND OF CONVECTION IS
BEGINNING TO WRAP AROUND THE NORTHERN SEMI-CIRCLE WHICH, COMBINED
WITH THE RAPID INTENSIFICATION OBSERVED OVER THE LAST 12HRS, SUGGEST
THAT KENNETH IS GOING THROUGH THE FIRST STAGE OF AN EYEWALL
REPLACEMENT CYCLE (ERC).
NO SIGNIFICANT CHANGE IN THE TRACK FORECAST, KENNETH MAINTAINS A
GENERAL WES-SOUTH-WESTWARD MOTION ON THE NORTHERN EDGE OF A BUILDING
LOW TO MID LEVELS SUBTROPICAL RIDGE. ON THE CURRENT TRACK, A LANDFALL
ON THE NORTH MOZAMBICAN COAST IS EXPECTED BY THE END OF THE AFTERNOON
OR IN THE EARLY EVENING (MOZAMBIQUE'S TIME), 100 TO 150KM NORTH OF
PEMBA.
IN THE MEDIUM TERM, THE TRACK OF THE RESIDUAL OVERLAND LOW IS
UNCERTAIN. IT COULD TRACK OVER THE NORTHERN MOZAMBICAN TERRITORIES
BEFORE COMING BACK OVER SEA SOMETIME IN THE BEGINNING OF NEXT WEEK.
THIS SCENARIO REMAINS VERY UNCERTAIN AS OF YET AND HAS THUS NOT BEEN
DISPLAYED IN THE OFFICIAL TRACK FORECAST.
GIVEN THE RECENT TREND, KENNETH HAS PROBABLY REACHED ITS PEAK
INTENSITY OVER THE LAST HOURS. THE VERY LAST IR IMAGES SHOW THE
BEGINNING OF A DEGRADATION OF THE SAT PRESENTATION, PROBABLY LINKED
TO THE ERC. KENNETH'S INTENSITY IS THUS EXPECTED TO WEAKEN SLIGHTLY
BEFORE LANDFALL, WHILE REMAINING OVER 100KT. THE RADIUS OF
DESCTRUCTIVE WINDS IS ALSO EXPECTED TO INCREASE SIGNIFICANTLY, WHICH
SHOULD WIDEN THE AREA OF MAXIMUM DANGER, BOTH IN TERMS OF STRONG
WINDS AND OF MARINE STORM SURGE.
KENNETH IS THEREFORE AN EXTREMELY DANGEROUS SYSTEM, WHICH WILL
SEVERELY IMPACT THE REGIONS NORTH OF PEMBA. THE SYSTEM WILL ALSO
GENERATE A LIFE-THREATENING STORM SURGE WHEN LANDING ON THE
MOZAMBICAN COASTS, WHICH CAN REACH BETWEEN 3 AND 5M IN SOME AREAS
SOUTH OF THE LANDFALL, TO WHICH MUST BE ADDED THE WAVE AND CYCLONIC
SWELL RUN-UP AND THE PHENOMENON OF HEAVY RAINFALL, WHICH CAN CAUSE
FLOODING IN MOZAMBIQUE.=

REMARKS:
250300Z POSITION NEAR 11.4S 42.3E.
TROPICAL CYCLONE 24S (KENNETH), LOCATED APPROXIMATELY 44 NM
NORTHWEST OF COMOROS ISLAND, HAS TRACKED WESTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY REVEALS A PERSISTENT PINHOLE EYE AND STRONG
CONVECTION SURROUNDING THE EYEWALL. THE INITIAL POSITION IS BASED
WITH HIGH CONFIDENCE ON THE EYE IN THE EIR IMAGERY. THE INITIAL
INTENSITY OF 115 KTS IS BASED ON THE 242345Z AUTOMATED DVORAK
TECHNIQUE ESTIMATE OF T6.0 (115 KTS), IN AGREEMENT WITH THE FMEE
DVORAK CURRENT INTENSITY ESTIMATE OF T6.0, BUT BELOW THE PGTW AND
KNES ESTIMATES OF T6.5 (127 KTS). A 242231Z SATCON ESTIMATE IS 120
KTS. WIND RADII HAVE BEEN ADJUSTED TO REFLECT THE COMPACT NATURE OF
THE SYSTEM. THE 250000Z OBSERVATION FROM HAHAYA INTERNATIONAL
AIRPORT ON COMOROS ISLAND, 30 NM TO THE SOUTH, REPORTED A PEAK
SUSTAINED WIND OF 41 KTS AND LOWEST PRESSURE OF 998MB AT 242000Z.
THE 250000Z OBSERVATION HAS WEAKENED TO 26 KTS SUSTAINED WIND AND
1002MB. LOW TO MODERATE (15-20 KT) VERTICAL WIND SHEAR, WARM (29-30
CELSIUS) SEA SURFACE TEMPERATURE, AND WELL-DEFINED WESTWARD AND
POLEWARD OUTFLOW ARE VERY SUPPORTIVE OF FURTHER INTENSIFICATION IN
THE NEAR TERM. FOR THE DURATION OF THE FORECAST, TC 24S WILL TRACK
ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE SOUTH. TC
24S IS EXPECTED TO BEGIN SLOWLY WEAKENING AS IT BEGINS TO FEEL
FRICTIONAL EFFECTS FROM LAND AND DIVERGENCE ALOFT WEAKENS. THE
CURRENT FORECAST HAS TC 24S DISSIPATING OVER LAND AFTER TAU 48.
HOWEVER, THE FLAT TERRAIN OF NORTHERN MOZAMBIQUE AND CONTINUED LOW
VWS MAY ALLOW THE CIRCULATION TO REMAIN ORGANIZED OVER LAND. A
MIDLATITUDE TROUGH WILL PASS BY TO THE SOUTH AND CAUSE THE CURRENT
DOMINANT STEERING STR TO RE-ORIENT AND ALLOW ANOTHER STR TO BUILD IN
FROM THE SOUTHWEST, BRINGING LOW-LEVEL SOUTHERLY TO SOUTHEASTERLY
FLOW THAT MAY PUSH THE REMNANTS OF TC 24S BACK OVER WATER AROUND TAU
96-120. NUMERICAL MODEL GUIDANCE IS IN EXCELLENT AGREEMENT IN THE
NEAR TERM, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK.
GUIDANCE AFTER THE FORECAST PERIOD DIVERGES SIGNIFICANTLY, WITH SOME
MODELS LOOPING THEN RECURVING TC 24S TO THE NORTHEAST AND RE-
EMERGING OVER WATER, SOME MODELS MOVING TC 24S NORTHWARD BUT
REMAINING OVER LAND, AND UKMET AND GALWEM TURNING TC 24S TO THE
SOUTH BACK OVER WATER. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250000Z IS
25 FEET. NEXT WARNINGS AT 250900Z, 251500Z, 252100Z AND 260300Z.
