The storm took at least 500 lives and caused more than $2 billion in property damage. It triggered landslides and widespread flooding that trapped thousands of people in remote villages for days.
Early Saturday flags around Taiwan were lowered to half staff, and government officials attended religious events paying homage to the storm victims.
Since the full dimensions of the Morakot disaster became clear about 12 days ago, President Ma-Ying-jeou has struggled to assuage widespread anger over the government's slow response.
His approval rating has now dropped to below 20 percent - a 30 percent decline in only three months
- amid an almost daily battering in Taiwan's hypercritical media - including in outlets normally friendly to the administration.
The Liberty Times - which normally supports the opposition - published details on Saturday of the $110 Japanese meal enjoyed by Ma's economic minister on the first day of a massive rescue operation aimed at saving the lives of thousands of flood-stranded villagers.
Three other senior officials - the vice-foreign minister, the defense minister and the Cabinet secretary-general
- have already offered to resign, their reputations pummeled by a growing perception that the government was either indifferent to the fate of Morakot's victims or incapable of offering them succor.
Ma has been visiting hard-hit areas in the south over the past two days, bowing before the families of the dead and promising that a planned $3 billion reconstruction program will be carried out with exemplary efficiency.
