2.C ADDITIONAL INFORMATION:
T=CI=5.0

OVER THE PAST 6 HOURS, TROPICAL CYCLONE DIKELEDI HAS ADOPTED AN
EMBEDDED CENTER PATTERN, WITH AN ESTIMATED DVORAK INTENSITY OF 5.0.
HOWEVER, THE LATEST AMSU-C MICROWAVE IMAGE FROM 0555Z SHOWS A VERY
POORLY DEFINED EYE DUE TO EASTERLY SHEAR, WHICH IS STILL VERY PRESENT.
MOREOVER, OBJECTIVE ANALYSES DO NOT ESTIMATE AN AVERAGE WIND ABOVE
60KT. THE CHOSEN INTENSITY IS THEREFORE 70KT.

DIKELEDI IS MOVING WESTWARDS TOWARDS THE NORTH OF MADAGASCAR WHILE
MAINTAINING ITS SPEED. THE SYSTEM SHOULD LAND OVER THE PROVINCE OF
ANTSIRANANA THIS SATURDAY EVENING. THEREAFTER, AS IT EXITS THE
MOZAMBIQUE CHANNEL, THE MOVEMENT CURVES TO THE WEST-SOUTH-WEST DUE
TO A SLIGHT WEAKNESS IN THE SUBTROPICAL RIDGE. THE DISPERSION BETWEEN
MODELS INCREASES SHARPLY FROM MONDAY ONWARDS, WITH A MORE OR LESS
RAPID TURN TO THE SOUTH-WEST AND THEN SOUTH, AND MORE OR LESS CLOSE TO
THE COAST OF MOZAMBIQUE (NAMPULA PROVINCE), DEPENDING ON THE LEVEL
OF THE STEERING FLOW AND THE GREATER OR LESSER EFFECT OF A TROUGH OVER
SOUTHERN AFRICA. THE RSMC FORECAST IS MAINLY A COMPROMISE BETWEEN
THE GFS, AROME AND IFS MODELS.

THE INTENSITY OF THE SYSTEM, EXPECTED BETWEEN SATURDAY EVENING AND
SUNDAY MORNING, SHOULD DECREASE AS IT PASSES OVER THE MALAGASY
LANDS, WHICH WILL WEAKEN IT. ONCE BACK OVER THE WARM WATERS OF THE
MOZAMBIQUE CHANNEL, THE SYSTEM SHOULD ONCE AGAIN ENCOUNTER GOOD
CONDITIONS AND INTENSIFY, SLOWLY AT FIRST ON SUNDAY, THEN MUCH MORE
RAPIDLY FROM MONDAY ONWARDS. IN THE EVENT OF TOO STRONG AN APPROACH
TO THE MOZAMBIQUE COAST, A MORE OR LESS SIGNIFICANT INTERACTION WITH
THE LAND COULD TEMPORARILY REDUCE OR LIMIT INTENSITY. IN THE CENTRAL
AND SOUTHERN MOZAMBIQUE CHANNEL, ENVIRONMENTAL CONDITIONS ARE
MOSTLY CONDUCIVE TO SIGNIFICANT INTENSIFICATION (LOW SHEAR, EXCELLENT
ALTITUDE DIVERGENCE, EXCEPTIONAL OCEANIC HEAT CONTENT). THE STAGE OF
INTENSE TROPICAL CYCLONE COULD THEN BE APPROACHED OR REACHED, EVEN IF
FORECASTING ON THESE DISTANT HORIZONS REMAINS UNCERTAIN.

IMPACTS ON INHABITED LAND IN THE NEXT 72 HOURS :

MADAGASCAR:
- GALE FORCE WINDS THIS SATURDAY ON THE EAST COAST OF ANTSIRANANA
PROVINCE, EXTENDING IN THE EVENING AND NIGHT TOWARDS THE WEST COAST.
HURRICANE FORCE WINDS EXPECTED SATURDAY EVENING NEAR THE LANDFALL
AREA (BETWEEN VOHEMAR AND ANTSIRANANA).
GALE EXTENDING TO CAPE SAINT-ANDRE ALONG MAHAJANGA PROVINCE UNTIL
SUNDAY EVENING, THEN POSSIBLE EXTENSION NEXT WEEK SOUTH OF CAPE
SAINT-ANDRE ON MONDAY AND TUESDAY.
- HEAVY RAINS UNTIL SUNDAY MORNING OVER ANTSIRANANA PROVINCE AND
NORTHERN TOAMASINA PROVINCE. ACCUMULATIONS OF OVER 100 MM, LOCALLY
200-300 MM IN 24H NEAR THE CENTER OF THE SYSTEM AND EXPOSED
MOUNTAINOUS RELIEF.
- VERY ROUGH TO HEAVY SEAS, LOCALLY VERY HEAVY FROM SATURDAY MORNING
UNTIL EVENING. WAVES OF 4 TO 6 METRES BETWEEN CAP D'AMBRE AND CAP EST.
NEAR THE LANDFALL AREA IN THE AFTERNOON, THEY MAY REACH 6 TO 9 METERS,
LOCALLY 10M,
- STORM SURGE OF 50CM TO 1M AROUND THE NORTHERN TIP OF MADAGASCAR,
LOCALLY 1M TO 1M50 OVER THE EXTREME NORTH-WEST OF THE DIANA REGION.
- WAVES OF UP TO 4M POSSIBLE ON THE WEST COAST OF MAHAJANGA PROVINCE
(NEAR CAP SAINT-ANDRE) BETWEEN SUNDAY EVENING AND MONDAY.

MAYOTTE:
- HEAVY RAIN FROM SATURDAY NIGHT TO SUNDAY AND ESPECIALLY DURING
SUNDAY. CUMULATIVE RAINFALL OF OVER 100-150 MM IN 12 HOURS POSSIBLE.
GALE FORCE WINDS POSSIBLE OVER THE SOUTH OF THE ISLAND.

COMOROS:
- HEAVY RAINS ON SUNDAY AROUND THE SYSTEM. CUMULATIVE RAINFALL CLOSE
TO 100 MM IN 24 HOURS LOCALLY, 150-200 MM ON EXPOSED RELIEF.

MOZAMBIQUE (COAST OF NAMPULA PROVINCE) :
- GALE FORCE WINDS LIKELY DURING THE DAY ON MONDAY AND INTO THE
FOLLOWING NIGHT. STORM POSSIBLE ON MONDAY AFTERNOON AND EVENING.
- HEAVY RAIN LIKELY FROM MONDAY. 100-200 MM IN 24H POSSIBLE LOCALLY
ALONG THE COAST.
- WAVES OF 4 TO 6 METRES POSSIBLE DURING THE DAY ON MONDAY AND UNTIL
TUESDAY MORNING.

2.C ADDITIONAL INFORMATION:
T=4.5 CI=5.0

OVER THE PAST 6 HOURS, DIKELEDI HAS CONTINUED ITS WESTWARD TRACK,
MAKING LANDFALL ON THE NORTHERN TIP OF MADAGASCAR AT AROUND 1630 UTC
BETWEEN THE TOWNS OF ANTSIRANANA AND VOHEMAR. IT WAS THEN AT THE
TROPICAL CYCLONE STAGE, WITH WINDS OF 70KT. ON LANDING, DIKELEDI LOST
INTENSITY AND WAS DOWNGRADED TO A SEVERE TROPICAL STORM WITH WINDS OF
60KT.

IN TERMS OF TRACK, FEW CHANGES. DRIVEN BY A POWERFUL SUBTROPICAL
RIDGE, DIKELEDI CONTINUED ITS GENERAL WESTWARD MOVEMENT UNTIL IT
TOUCHED THE NORTHERN TIP OF MADAGASCAR THIS EVENING. THEN, WITH A
WEAKENING RIDGE OVER THE MOZAMBIQUE CHANNEL, THE SYSTEM SHOULD
GRADUALLY TILT ITS TRACK TO THE WEST-SOUTH-WEST AND THEN SOUTH-WEST
OVER THE NEXT 48 HOURS. IT WILL THEN TURN SOUTH THEN SOUTHEAST ON
TUESDAY. THERE IS A SMALL DISPERSION BETWEEN MODELS AS IT EXITS THE
SEA FROM DIKELIDI, THEN IT INCREASES SHARPLY FROM MONDAY WITH A MORE
OR LESS RAPID TURN AND MORE OR LESS CLOSE TO THE COASTS OF MOZAMBIQUE
(NAMPULA PROVINCE), DEPENDING ON THE GREATER OR LESSER EFFECT OF A
TROUGH OVER SOUTHERN AFRICA. THE RSMC FORECAST IS A COMPROMISE
BETWEEN THE DIFFERENT GUIDANCE AVAILABLE, AND IS CLOSER TO THE AROME
SCENARIO, WITH A TURN MORE TOWARDS THE CENTER OF THE CHANNEL (NOTE
THAT THE 06Z GFS RUN NOW ALSO TAKES THE SYSTEM TOWARDS THE CENTER OF
THE CHANNEL AND NO LONGER TOWARDS THE COAST OF MOZAMBIQUE, WHICH
REINFORCES OUR FORECAST).

IN TERMS OF INTENSITY, CURRENTLY OVER THE NORTHERN TIP OF MADAGASCAR,
DIKELEDI WILL WEAKEN CONSIDERABLY OVER THE NEXT FEW HOURS AND BE
TEMPORARILY DOWNGRADED TO A MODERATE TROPICAL STORM. ON REACHING THE
MOZAMBIQUE CHANNEL, THE SYSTEM WILL MOVE THROUGH VERY WARM WATERS AND
A HUMID ENVIRONMENT, ENABLING IT TO RESTRUCTURE RAPIDLY. HOWEVER,
WIND SHEAR WILL INITIALLY LIMIT ITS INTENSIFICATION A LITTLE
TOMORROW, BEFORE DIKELEDI RAPIDLY INTENSIFIES AS IT EASES OVERNIGHT.
THERE IS STILL CONSIDERABLE UNCERTAINTY ABOUT THE INTENSITY OF THE
SYSTEM, AS THIS WILL DEPEND ON ITS FINAL TRACK. INDEED, WITH A
CENTRAL TRACK LIKE THE ONE PROPOSED BY THE RSMC, THERE ARE FEW BRAKES
ON DIKELEDI'S INTENSIFICATION UP TO THE STAGE OF AN INTENSE TROPICAL
CYCLONE (LOW SHEAR, EXCELLENT ALTITUDE DIVERGENCE, EXCEPTIONAL
OCEANIC HEAT CONTENT). HOWEVER, IF THERE IS INTERACTION WITH AFRICAN
COASTS, INTENSIFICATION WILL BE SLOWER. IN ADDITION, A POSSIBLE
REPLACEMENT OF THE EYEWALL DURING ITS MATURE PHASE COULD CAUSE ITS
INTENSITY TO FLUCTUATE.

IMPACTS ON INHABITED LAND IN THE NEXT 72 HOURS :

MADAGASCAR:
- STORM-FORCE WINDS UNDERWAY OVER THE PROVINCE OF ANTSIRANANA,
GRADUALLY EVACUATING IN THE SECOND HALF OF THE NIGHT.
GALE EXTENDING TO CAPE SAINT-ANDRE ALONG MAHAJANGA PROVINCE UNTIL
SUNDAY EVENING, THEN POSSIBLE EXTENSION NEXT WEEK SOUTH OF CAPE
SAINT-ANDRE ON MONDAY AND TUESDAY.
- HEAVY RAINS UNDERWAY UNTIL SUNDAY MORNING OVER ANTSIRANANA PROVINCE
AND NORTHERN TOAMASINA PROVINCE. RAINFALL TOTALS OF OVER 100 MM,
LOCALLY 200-300 MM IN 24 HOURS NEAR THE CENTER OF THE SYSTEM AND
EXPOSED MOUNTAINOUS TERRAIN.
- VERY ROUGH TO HEAVY SEAS, LOCALLY VERY HEAVY. WAVES OF 4 TO 6
METRES BETWEEN CAP D'AMBRE AND CAP EST DIMINISHING RAPIDLY.
- WAVES OF 4 METRES POSSIBLE ON THE WEST COAST OF MAHAJANGA PROVINCE
(NEAR CAP SAINT-ANDRE) BETWEEN SUNDAY EVENING AND MONDAY.

MAYOTTE:
- GALE FORCE WINDS POSSIBLE OVER THE SOUTH OF THE ISLAND ON SUNDAY.
- HEAVY RAIN UNTIL THE END OF THE DAY SUNDAY UNDER THE PERIPHERAL
BANDS. TOTAL RAINFALL OVER 100-150 MM IN 12 HOURS POSSIBLE.

COMOROS :
- HEAVY RAINS ON SUNDAY AROUND THE SYSTEM. CUMULUS CLOSE TO 100 MM
IN 24H LOCALLY, 150-200 MM ON THE EXPOSED RELIEF.

MOZAMBIQUE (COAST OF NAMPULA PROVINCE):
- GALE FORCE WINDS LIKELY DURING THE DAY ON MONDAY AND INTO THE
FOLLOWING NIGHT. STORM FORCE WINDS POSSIBLE ON MONDAY AFTERNOON AND
EVENING.
- HEAVY RAIN LIKELY FROM MONDAY. 100-200 MM IN 24H POSSIBLE LOCALLY
ALONG THE COAST.
- WAVES OF 4 TO 6 METRES POSSIBLE DURING THE DAY ON MONDAY AND UNTIL
TUESDAY MORNING.=

  8. SUMMARY:
  9.    INITIAL POSITION: 12.9S 49.0E
  10.    INITIAL INTENSITY: 75 KTS
  11.    GEOGRAPHIC REFERENCE: 370 NM NORTH-NORTHEAST OF ANTANANARIVO,
  12. MADAGASCAR
  13.    MOVEMENT PAST 6 HOURS: WEST-SOUTHWESTWARD AT 13 KTS
  14.    SIGNIFICANT WAVE HEIGHT: 29 FEET

  15. SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION:
  16. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS DEEP
  17. CONVECTION REDEVELOPING OVER THE WESTERN PORTION OF THE CIRCULATION
  18. IN THE MOZAMBIQUE CHANNEL FOLLOWING A SHORT DISRUPTION DUE TO
  19. PASSAGE OVER THE NORTHERN TIP OF MADAGASCAR. THE INITIAL POSITION
  20. IS PLACED WITH MEDIUM CONFIDENCE BASED ON GEOSTATIONARY SATELLITE
  21. POSITION ESTIMATES FROM PGTW AND DEMS. THE INITIAL INTENSITY OF 75
  22. KTS IS ASSESSED WITH MEDIUM CONFIDENCE BASED ON A CONSENSUS OF
  23. AVAILABLE SUBJECTIVE DVORAK AND AUTOMATED INTENSITY ESTIMATES
  24. LISTED BELOW.

  25. INITIAL WIND RADII BASIS: OBJECTIVE BEST TRACK

  26. CURRENT STEERING MECHANISM: SUBTROPICAL RIDGE (STR) TO THE SOUTH

  27. AGENCY DVORAK AND AUTOMATED FIXES:
  28.    PGTW: T4.5 - 77 KTS
  29.    DEMS: T4.5 - 77 KTS
  30.    FMEE: T5.0 - 90 KTS

  36.    OUTFLOW: STRONG WESTWARD

  37. ANALYSIS CONFIDENCE:
  38.    INITIAL POSITION: MEDIUM
  39.    INITIAL INTENSITY: MEDIUM
  40.    INITIAL WIND RADII: MEDIUM

  41. 3. FORECAST REASONING.

  42. SIGNIFICANT FORECAST CHANGES: FORECAST INTENSITIES HAVE INCREASED
  43. FROM THE PREVIOUS WARNING FOR EACH TAU DUE TO ANTICIPATED FAVORABLE
  44. ENVIRONMENTAL SUPPORT IN THE MOZAMBIQUE CHANNEL. THE PEAK INTENSITY
  45. HAS INCREASED FROM 80 KNOTS IN THE PREVIOUS WARNING TO 105 KNOTS IN
  46. THE CURRENT WARNING.

  47. FORECAST DISCUSSION: TC 07S IS EXPECTED TO FOLLOW THE PERIPHERAL
  48. FLOW ASSOCIATED WITH THE CURRENT STEERING RIDGE THROUGHOUT THE
  49. FORECAST PERIOD. OVER THE NEXT SEVERAL DAYS, A MID-LATITUDE TROUGH
  50. WILL AMPLIFY OVER THE SOUTHERN PORTION OF THE AFRICAN CONTINENT,
  51. GRADUALLY ERODE THE STEERING RIDGE, AND INDUCE A BREAK OVER THE
  52. MOZAMBIQUE CHANNEL. TC 07S WILL TURN POLEWARD TOWARD THE BREAK IN
  53. THE RIDGE BY TAU 36 AND CONTINUE TO ROUND THE RIDGE AXIS
  54. THEREAFTER. AFTER TAU 96, THE SYSTEM WILL ACCELERATE AND BEGIN TO
  55. INTERACT WITH THE MID-LATITUDE TROUGH TO THE WEST, INDUCING THE
  56. FIRST STAGE OF A LIKELY PROLONGED EXTRATROPICAL TRANSITION. SLOW
  57. INTENSIFICATION IS PROBABLE IN THE NEAR TERM DESPITE HIGH SEA
  58. SURFACE TEMPERATURES AND FAVORABLE OUTFLOW ALOFT AS THE SYSTEM IS
  59. POSITIONED TO THE NORTH OF AN UPPER-LEVEL RIDGE AXIS IN AN AREA OF
  60. PERSISTENT, MODERATE EASTERLY VERTICAL WIND SHEAR. AFTER TAU 24,
  61. STEADY TO RAPID INTENSIFICATION IS ANTICIPATED AS THE SYSTEM MOVES
  62. UNDER THE UPPER-RIDGE AXIS AND BENEFITS FROM LOW VERTICAL WIND
  63. SHEAR, FAVORABLE OUTFLOW ALOFT, AND PASSAGE OVER VERY WARM WATER.
  64. WESTERLY VERTICAL WIND SHEAR INDUCED BY THE UPPER-LEVEL FLOW AHEAD
  65. OF THE AFOREMENTIONED MID-LATITUDE TROUGH WILL INDUCE WEAKENING IN
  66. THE LATER TAUS.

  67. MODEL DISCUSSION: NUMERICAL MODEL GUIDANCE IS IN VERY GOOD
  68. AGREEMENT REGARDING THE OVERALL FORECAST SCENARIO, INCLUDING A
  69. POLEWARD TURN AROUND THE STEERING RIDGE AXIS AND PASSAGE OVER THE
  70. MOZAMBIQUE CHANNEL. THE GUIDANCE PACKAGE IS BRACKETED ON THE WEST
  71. BY THE ECMWF DETERMINISTIC AND ENSEMBLE MEAN SOLUTIONS AND ON THE
  72. RIGHT BY THE GALWEM SOLUTION. THE DISTRIBUTION OF CONSENSUS MODEL
  73. AND ENSEMBLE MEMBER TRACKS IS FAIRLY EVEN, REFLECTING SLIGHT
  74. DIFFERENCES IN THE SPEED AND ORIENTATION OF THE EXPECTED POLEWARD
  75. TURN BUT A CONSISTENT OVERALL PICTURE. THE CURRENT JTWC TRACK
  76. FORECAST IS CONSISTENT WITH THE PRIMARY MODEL GROUPING AND LIES
  77. JUST SLIGHTLY TO THE EAST OF THE PREVIOUS FORECAST. MORE SPREAD IS
  78. EVIDENT IN THE INTENSITY GUIDANCE, WITH A RANGE OF SOLUTIONS FROM
  79. SLOW INTENSIFICATION IN THE GFS AND SHIPS FORECASTS TO STEADY TO
  80. RAPID INTENSIFICATION IN THE LATEST HAFS AND HWRF RUNS. THE CURRENT
  81. FORECAST ALIGNS ABOVE THE INTENSITY CONSENSUS GIVEN ANTICIPATED
  82. FAVORABLE ENVIRONMENTAL CONDITIONS AND SUPPORT FROM THE AVAILABLE
  83. MESOSCALE MODELS. THE SYSTEM COULD EASILY PEAK ABOVE 105 KNOTS IN
  84. THE CENTRAL MOZAMBIQUE CHANNEL IF CONDITIONS REMAIN FAVORABLE,
  85. WARRANTING FURTHER UPWARD ADJUSTMENTS TO THE INTENSITY IN
  86. SUBSEQUENT FORECASTS.

  87. FORECAST CONFIDENCE:
  88.    TRACK 0 - 72 HR: MEDIUM
  89.    TRACK 72-120 HR: MEDIUM
  90.    INTENSITY 0 - 72 HR: MEDIUM
  91.    INTENSITY 72-120 HR: LOW//

2.C ADDITIONAL INFORMATION:
IN THE LAST 6 HOURS, DIKELEDI LANDED ON THE NORTHERN TIP OF
MADAGASCAR AT AROUND 1630 UTC BETWEEN THE TOWNS OF ANTSIRANANA AND
VOHEMAR, AND EMERGED CLOSE TO NOSY-BE A FEW HOURS LATER. THE PASSAGE
OVER THE MALAGASY LANDMASS CONSIDERABLY REDUCED ITS INTENSITY AND
DAMAGED ITS CONFIGURATION. IT IS ESTIMATED TO BE A MODERATE TROPICAL
STORM WITH WINDS OF 45KT.

IN TERMS OF TRACK, LITTLE HAS CHANGED. WITH A WEAK SUBTROPICAL RIDGE
OVER THE MOZAMBIQUE CHANNEL, THE SYSTEM IS SET TO GRADUALLY TILT ITS
TRACK TO THE WEST-SOUTH-WEST AND THEN SOUTH-WEST OVER THE NEXT 48
HOURS. IT WILL THEN TURN SOUTH AND THEN SOUTHEAST ON TUESDAY. THE
MODELS ARE HIGHLY DISPERSED FROM MONDAY ONWARDS. IN FACT, DEPENDING
ON THE INFLUENCE OF THE TROUGH OVER SOUTHERN AFRICA, DIKELEDI'S TRACK
COULD IMPACT THE MOZAMBIQUE COAST OVER THE PROVINCE OF NAMPULA ON
MONDAY, OR PASS MUCH FURTHER INTO THE CENTER THE CHANNEL. SIMILARLY,
IN THE LONGER TERM, THE PREFERRED SCENARIO REMAINS A PASSAGE TO THE
SOUTH OF MADAGASCAR, BUT A SCENARIO PASSING OVER THE SOUTHERN TIP OF
GRANDE TERRE CANNOT BE RULED OUT. THE RSMC FORECAST IS A COMPROMISE
BETWEEN THE DIFFERENT GUIDANCE AVAILABLE, MOVING CLOSER TO THE AROME
SCENARIO WITH A TURN MORE TOWARDS THE CENTER OF THE CHANNEL.

IN TERMS OF INTENSITY, DIKELEDI WEAKENED CONSIDERABLY FOLLOWING ITS
PASSAGE OVER MADAGASCAR. NOW BACK OVER THE WATERS OF THE MOZAMBIQUE
CHANNEL, THE SYSTEM WILL BE CIRCULATING IN VERY WARM WATERS AND A
HUMID ENVIRONMENT, ENABLING IT TO RESTRUCTURE RAPIDLY. HOWEVER, THE
WIND SHEAR WILL INITIALLY LIMIT ITS INTENSIFICATION A LITTLE THIS
MORNING, BUT DIKELEDI WILL RAPIDLY INTENSIFY AS IT DIMINISHES
OVERNIGHT. THERE IS STILL CONSIDERABLE UNCERTAINTY ABOUT THE
INTENSITY OF THE SYSTEM, AS THIS WILL DEPEND ON ITS FINAL TRACK. IN
FACT, WITH A CENTRAL TRACK LIKE THE ONE PROPOSED BY THE RSMC, THERE
ARE FEW OBSTACLES TO THE INTENSIFICATION OF DIKELEDI UP TO THE STAGE
OF AN INTENSE TROPICAL CYCLONE (LOW SHEAR, EXCELLENT ALTITUDE
DIVERGENCE, EXCEPTIONAL OCEANIC HEAT CONTENT). HOWEVER, IF THERE IS
INTERACTION WITH AFRICAN COASTS, INTENSIFICATION WILL BE SLOWER. IN
ADDITION, A POSSIBLE REPLACEMENT OF THE EYEWALL DURING ITS MATURE
PHASE COULD CAUSE ITS INTENSITY TO FLUCTUATE.

IMPACTS ON INHABITED LAND IN THE NEXT 72 HOURS :

MADAGASCAR:
- GALE STILL IN PROGRESS OVER WESTERN ANTSIRANANA PROVINCE,
DISSIPATING IN THE NEXT FEW HOURS. GALE EXTENDING TO CAPE SAINT-ANDRE
ALONG MAHAJANGA PROVINCE UNTIL THIS EVENING, THEN POSSIBLE EXTENSION
NEXT WEEK SOUTH OF CAPE SAINT-ANDRE ON MONDAY AND TUESDAY.
- HEAVY RAINS UNDERWAY OVER ANTSIRANANA PROVINCE. ADDITIONAL
ACCUMULATIONS OF 100MM POSSIBLE BEFORE AN IMPROVEMENT DURING THE DAY.
HEAVY RAINS ALONG THE COAST OF MAHAJANGA PROVINCE POSSIBLE TODAY.
100MM CUMULATIVE RAINFALL POSSIBLE DURING THE DAY.

MAYOTTE :
- GALE FORCE WINDS POSSIBLE OVER THE SOUTH OF THE ISLAND IN THE NEXT
FEW HOURS.
- HEAVY RAIN UNTIL THE END OF THE DAY UNDER THE PERIPHERAL BANDS.
TOTAL RAINFALL OVER 100-150 MM IN 12 HOURS POSSIBLE.

COMOROS :
- HEAVY RAIN TODAY AROUND THE SYSTEM. CUMULUS CLOSE TO 100 MM IN 24H
LOCALLY, 150-200 MM ON EXPOSED RELIEF.

MOZAMBIQUE (COAST OF NAMPULA PROVINCE):
- GALE FORCE WINDS POSSIBLE DURING THE DAY ON MONDAY AND INTO THE
FOLLOWING NIGHT. REDUCED RISK OF STORM-FORCE WINDS ON MONDAY
AFTERNOON AND EVENING.
- HEAVY RAIN POSSIBLE FROM MONDAY. 100-200 MM IN 24H POSSIBLE LOCALLY
ALONG THE COAST.
- WAVES OF UP TO 4 METRES POSSIBLE DURING THE DAY ON MONDAY AND UNTIL
TUESDAY MORNING.=
