Brasília-Sao Paulo’s heavy rain landslides and floods have killed at least 19 people, including seven children, since Friday, public security officials said on Sunday.
According to São Paulo state officials, nine others were injured in the rain, four more were missing, and about 500 families were homeless throughout the state.
João Doria, Governor of São Paulo, said he had jumped over the flooded area on Sunday and approved R $ 15 million ($ 2.79 million) in emergency assistance to the affected cities.
The federal government said in a statement from the Ministry of Regional Development that it was monitoring the situation.
The most devastated municipalities around Greater São Paulo include Alger, Francisco Morato, Embudas Artes and Franco da Rocha.
Storms also caused damage in the northern parts of Varzea Paulista, Campo Limpo Paulista, Jau, Kapivari, Montemor, and Rafard, state officials said.
Since December, heavy rains have caused fatal floods in northeastern Brazil, threatening to delay harvests in the Midwest, and temporarily suspending minasing operations in Minas Gerais.
