The storm, which hit China's southwestern Guangxi province in early July, brought historic rains and severe flooding.
Two cities, Nanning and Guigang, were the most heavily affected.
At the time, officials reported 39 deaths.
It is not uncommon for officials to update a death toll days after an incident, although in this instance, more than a month had passed since the initial storm hit.
In Guangxi, cumulative rainfall was 10cm to 40cm in some areas and more than 90cm in hard-hit areas, the national meteorological centre said in July.
Of the total death toll, 107 people died of floods caused by the collapse of six dams in Nanning, according to state media.
The government deployed military rescue teams during initial stages of the flooding to rescue students and teachers trapped by high flood waters in Guigang.
The city estimated 14 billion yuan ($A2.9 billion) of direct economic damage from the storm.
Across Asia, climate change has supercharged storms, and the continent is warming nearly twice as fast as the global average.
