Severe Tropical Storm Dongo (Joint Typhoon Warning Center designation: 06S) was the fifth tropical disturbance and fourth named storm of the 2008–09 South-West Indian Ocean cyclone season. Dongo developed out of an area of low pressure near the remnants of Severe Tropical Cyclone Billy early on January 7. The low was quickly declared a tropical disturbance later that day, and a tropical depression the following day. Shortly after being declared a tropical depression, it was further upgraded to a moderate tropical storm and given the name Dongo. Convection associated with Dongo decreased as it began to exhibit hybrid features. Late on January 10, convection quickly increased and Dongo intensified into a severe tropical storm early the next morning. Upon becoming a severe tropical storm, Dongo reached its peak intensity with winds of 95 km/h (60 mph 10-minute winds). Despite approaching cooler waters, the storm remained a severe tropical storm until transitioning into an extratropical cyclone early on January 12. The extratropical remnants of Dongo persisted for another two days before becoming non-tropical.
