Tropical Cyclone EDZANI is now a Category 2B storm on FEWW Hurricane Scale
JTWC Reported:
10 January 2010 at 03:00UTC position near 20.4ºS 72.1ºE
Tropical cyclone EDZANI (TC 07S), located approximately 1,835 km (950 nm) east of La Reunion, has tracked south-southwestward at 25 km/hr (14 knots) over the past six hours. Animated infrared satellite imagery shows the Well defined eye feature has weakened and is no longer visible in Infrared imagery. The most recent dvorak fix from pgtw indicated the eye feature had weakened to spiral band curvature. Animated enhanced water vapor imagery indicates the favorable equatorward outflow has decreased over the past 12 hours. As EDZANI tracks southward sea surface temperatures (SST) are beginning to decrease. The combined effect of decreasing outflow and cooler SST values have caused the ongoing weakening trend in the intensity. The intensity is expected to continue the weakening trend throughout the forecast period as SST values decrease further and increased interaction with the mid-latitude westerlies causes vertical wind shear values to increase.
The subtropical ridge (STR) to the southeast remains the dominant steering source, however, a mid-latitude trough to the southwest is going to cause EDZANI to move southward and slightly south-southeast until the trough moves further east and its influence is lost. … Maximum significant wave height at 10 00:00UTC was 9 meters (27 feet).

UPDATE: 9 January 2010 at 03:00UTC
EDZANI Gradually Weakening
Tropical Cyclone EDZANI is now a category 4A storm on FEWW Hurricane Scale
- Time/Date: 9 January 2010 – 03:00UTC
- Position: 17.2ºS, 75.0ºE
- Sustained Movement: 235 degrees
- Forward speed: 17km/hr (9 kt)
Current wind distribution:
- Maximum Sustained winds: 225 km/hr (~ 120 kt)
- Maximum Gusts: 305 km/hr (~ 150 kt)
- Maximum significant wave height: 11 meters (34 feet)
- Sources: JTWC and Others
JTWC Reported:
Tropical cyclone (TC) 07S (EDZANI), located approximately 2,140 km (1155 nm) east of La Reunion has tracked southwestward at 17 km/hr (09 knots) over the past six hours. Animated infrared satellite imagery shows the low level circulation center (LLCC) has maintained a steady speed and direction over the past 12 hours. The well defined eye feature has been on a steady weakening trend over the past 12 hours as well, becoming cloud filled around [January 08, 22:00UTC]. Model guidance indicates that a mid-latitude trough will begin to weaken the deep subtropical ridging (STR) to the southeast of EDZANI and will cause a more southward track between tau 24 and 96. The trough is expected to move eastward allowing the STR to begin building to the south of EDZANI around tau 96, pushing the system slightly westward. A secondary mid-latitude trough tracking to the south of EDZANI will begin to capture the LLCC keeping it on a predominantly southward track even as the STR re-develops. Complete capture of the LLCC is not expected until after tau 120. Decreasing sea surface temperatures and increasing vertical wind shear values beyond tau 60 will cause EDZANI to weaken slowly over the next five days. Maximum significant wave height on January 9 at 00:00UTC is 11 meters (34 feet). Edited by FEWW.

Tropical Cyclone EDZANI is now a category 4B storm on FEWW Hurricane Scale
Fed on warm ocean waters, facing little vertical wind shear and showing strong upper level outflow, EDZANI continues to strengthen.
- Time/Date: 8 January 2010 – 03:00UTC
- Position: 15.4ºS, 77.9ºE
- Sustained Movement: 245 degrees
- Forward speed: 13km/hr (7 kt)
- A category 4 storm on Saffir-Simpson hurricane scale
Current wind distribution:
- Maximum Sustained winds: 235 km/hr (~ 125 kt)
- Maximum Gusts: 280 km/hr (~ 150 kt)
- Sources: JTWC and Others
Observation:
- Tropical Cyclone EDZANI (TC 07S) is currently located about 1,075 km (580 nm) SE of Diego Garcia, tracking west-southwestward at 13 km/hr (7 knots), and is expected to continue in its current track during the next 24 hours. The storm should weaken as it heads toward cooler waters.
- EDZANI has continued to intensify during the past 12 hours assisted by warm ocean waters (27ºC ~ 80ºF) in the absence of high vertical wind shear, and helped by strong upper Level outflow.
- The cyclone has developed a 30 km (~15 nm) diameter eye and “is tracking west-southwestward in the peripheral flow around a deep subtropical Ridge situated to the south and east.” JTWC reported.
