Tropical Cyclone Edzani

Tropical Cyclone Edzani

Image Location

Tropical Cyclone Edzani formed over the Southern Indian Ocean in early January 2010 and intensified rapidly, according to the U.S. Navy’s Joint Typhoon Warning Center. As of January 7, 2010, the storm had maximum sustained winds of 100 knots (185 kilometers per hour) and gusts up to 125 knots (230 kilometers per hour). The storm’s center was roughly 590 nautical miles (1,100 kilometers) southeast of Diego Garcia

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’sAqua satellite captured this image of Edzani over the open ocean at 1:55 p.m. Calcutta time (8:25 UTC) on January 7, 2010. In this image, Edzani has a well-defined eye surrounded by spiral arms extending hundreds of kilometers from the storm’s center.

The high-resolution image provided above is at MODIS’ full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Forecast and Intensity ======================== 24 HRS 10.5S 92.4E - 25 knots (Tropical Depression) 48 HRS 11.3S 90.2E - 30 knots (Tropical Depression) 72 HRS 12.4S 87.8E - 35 knots (CAT 1) http://www.wunderground.com/blog/HadesGodWyvern/comment.html?entrynum=23 Mauritius Meteorological Services Tropical Cyclone Advisory Number SIXTEEN CYCLONE TROPICAL INTENSE EDZANI (08-20092010) 10:00 AM Réunion January 8 2010 ====================================== At 6:00 AM UTC, Intense Tropical Cyclone Edzani (915 hPa) located at 15.6S 77.7E has 10 minute sustained winds of 110 knots with gusts of 155 knots. The cyclone was reported as moving west-southwest at 6 knots.

EDZANI is expected therefore to stay steady or weaken slowly until 36-48 hrs, beyond its intensity should weaken more rapidly. The steering flow is a deep ridge in the southeast of the system. At the end of the range forecast, atrough south of the system should steer it more southern ECMWF ensemble prediction system gives 2 equiprobably scenario, one with recurve movement towards the trough, the other one without this forecast is a consensus of the available determinist Numerical Weather Prediction models which are in rather good agreement on the track and the speed of the system.
