At least 72 people were killed and 78 000 left homeless in Madagascar in the wake of Tropical Storm Irina, the disaster management agency said Wednesday.
The storm struck on 26 February, but spun off a series of storms which have drenched the Indian Ocean island over the last week.
The district of Ifanadiana, 400 kilometres southeast of the capital, was hardest hit with 47 dead, the National Office for Disaster and Catastrophe Management said.
The road leading to the district re-opened Wednesday, but aid teams were already in the area delivering emergency supplies and medicines.
Irina was the second killer storm of the season. Last month, tropical cyclone Giovanna left 35 people dead and many more injured.
Madagascar's storm season normally runs from November through February and costs dozens of lives every year.
