Figure 1: Image of Tropical Storm Alenga (middle right) and Tropical Storm 02S (bottom left).The first two tropical cyclones of the Southern Hemisphere tropical season have formed in the Southwest Indian Ocean region. Alenga gained a name yesterday and was destined to become a Category 2 equivalent cyclone. However shear and cooler waters prevented that and Alenga has now started to weaken. Alenga is a 50mph tropical cyclone and should move into the Australian region sometime tonight or tomorrow. It is unlikely that Alenga will survive long enough to impact Australia as a significant cyclone.
The other area of interest is our second tropical cyclone of the Southern Hemisphere: TC 02S. The Joint Typhoon Warning Center is observing this as a tropical storm, while Meteo France (MF) is only observing this as a tropical depression. The official forecast from JTWC keeps 02S steady at 40mph, while MF strengthens it to gain a name. The track for now is for the system to continue a westward movement until dissipation. The next name is Benilde.
Other than a worthless tropical depression that formed in the Western Pacific, the rest of the tropics have been quiet.
