Satellite Image
Tropical cyclones Alenga and 02S can be seen swirling over the southern Indian Ocean, far from land areas.
Two separate areas of disturbed weather over remote parts of the southern Indian Ocean formed into the season’s first cyclones for the region within a one-day period.

Cyclone Alenga formed to the west of Australia’s territory of the Cocos (Keeling) Islands.

It then traveled on a mainly southeasterly course while strengthening to Category 2 force.

The storm later dissipated over cooler waters to the west of Australia.

Cyclone 02S attained only minimal tropical storm strength before dissipating to the north of Rodrigues Island, part of the island nation of Mauritius.
