1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94B) PREVIOUSLY LOCATED 
NEAR 7.4N 88.4E, IS NOW LOCATED NEAR 7.6N 88.2E, APPROXIMATELY 490 
NM EAST OF COLOMBO, SRI LANKA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY SHOWS PERISTENT DEEP CONVECTION OBSCURING THE LOW LEVEL 
CIRCULATION CENTER (LLCC). AN 132141Z SSMIS F-16 91GHZ MICROWAVE 
IMAGE SHOWS DEEP CONVECTION OVER THE LLCC WITH BANDING FORMING TO 
THE NORTH AND WEST OF THE CIRCULATION. 94B IS CURRENTLY IN A 
FAVORABLE ENVIRONMENT WITH HIGH SEA SURFACE TEMPERATURES (28 TO 30 
CELSIUS) AND EXCELLENT POLEWARD OUTFLOW, AND IS SITTING IN A SMALL 
POCKET OF LOW VERTICAL WIND SHEAR (5 TO 10 KNOTS) WITH HIGHER VWS 
VALUES TO THE NORTHWEST. GLOBAL MODELS AGREE ON A NORTHWEST 
TRAJECTORY WITH INTENSIFICATION OVER THE NEXT COUPLE DAYS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS REMAINS HIGH. SEE REF A (WTIO21 PGTW 140300) FOR FURTHER 
DETAILS.
      (2) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91S) PREVIOUSLY LOCATED 
NEAR 7.6S 91.4E, IS NOW LOCATED NEAR 8.0S 90.7E, APPROXIMATELY 443 
NM NORTHWEST OF COCO ISLANDS. ENHANCED MULTISPECTRAL INFRARED 
SATELLITE IMAGERY AND A PARTIAL 131920Z AMSR2 89 GHZ MICROWAVE IMAGE 
SHOW A CONSOLIDATING LOW LEVEL CIRCULATION (LLC) WITH FRAGMENTED, 
FORMATIVE BANDING AND PERSISTENT DEEP CONVECTION. UPPER LEVEL 
ANALYSIS INDICATES MODERATE TO HIGH (20-30 KNOT) VERTICAL WIND SHEAR 
AND VERY GOOD POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES (26-28 
CELSIUS) ARE FAVORABLE FOR DEVELOPMENT. A RECENT PARTIAL ASCAT PASS 
REVEALS A BROAD, SYMMETRIC CIRCULATION WITH STRONGER WINDS WRAPPING 
INTO THE LLC FROM THE NORTHEAST. GLOBAL MODELS ARE IN GOOD AGREEMENT 
THAT 91S WILL TRACK SOUTHWESTWARD AND INTENSIFY OVER THE NEXT 
SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 
28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF B 
(WTXS21 PGTW 132100) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
3. JUSTIFICATION FOR REISSUE: UPDATED AREA IN PARA 1.B.(1) FOR TCFA 
REISSUE.//

Cyclone Image & Animation

Enlarge to see Animation Here you see the latest image of the cyclone activity in the Indian Ocean.

Normally there is an update every 4 hours, like the current satellite image of the cyclone itself. With the forecast, the direction, as well as strength and location with date & time.

Cyclone Infos & Formation explained

Who determines the cyclone names?

Cyclone names are selected in advance by the RA I Tropical Cyclone Committee of the World Meteorological Organization.

Members
Botswana - Comoros - France (RSMC La Réunion Tropical Cyclone Centre) - Kenya - Lesotho - Madagascar - Malawi - Mauritius - Mozambique - Namibia - Seychelles - South Africa - Swaziland - United Republic of Tanzania - Zimbabwe
Cyclone Description

Classification of cyclones depends on the maximum continuous wind speed.

Cyclone Names

Cyclones migrating from the Australian observation area over the 90th degree of longitude are given a new name.

The other way around, they keep their name.

Info Here in our picture it is very well explained what it takes for a cyclone to form and how it is constructed. In which latitude they arise and which conditions must prevail.

Very Intense Tropical Cyclone Fantala

is, with 1 min peaks of 285 km/h, the strongest tropical cyclone measured in the southwestern Indian Ocean.

What is a Cyclone?

A cyclone is an atmospheric disturbance in tropical regions that causes strong vertical winds and heavy rainfall. The pressure in the centre is minimal.

What is the DANGEROUS thing about a cyclone

Wind strength: winds reach their maximum values at the periphery of the eye. Precipitation: torrential rains accompanying the system cause flooding, landslides or landslides. The sea: the rise in mean sea level linked to the passage of the cyclone combines with the enormous waves of the cyclonic swell to undermine the coastline or flood the coastal plains.

Who detects and monitors cyclones?

Meteo-France Reunion is a CMRS (Centre Météorologique Spécialisé "Cyclone") officially in charge of detecting and monitoring tropical disturbances in the South-West Indian Ocean.

Mauritius Cyclone Warning System

Cyclone Classes When they come into effect
Class 1 If possible 36 to 48 hours before Mauritius, gusts of up to 120 km/h are to be expected.
Class 2 Issued to allow, as far as practicable, 12 hours of daylight before gusts of 120 km/h occur
Class 3 Issued to allow, as far as possible, 6 hours of daylight before gusts of 120 km/h occur.
Class 4 It is issued when gusts of 120 km/h have been registered in some places and are expected.
Cyclone Warning Removed It is issued when there is no longer a risk of gusts above 120 km/h.
