The other six people, including four children from the same family, were killed by mudslides that occurred during the storm.
Sao Paulo Emergency Managing Center informed that Tuesday was the most rainy day in the city in the past 10 years.
The storms have caused the most important rivers in the city, Tiete and Pinheiros, to overflow, blocking the main expressways and leading to over 100 kilometers of traffic jams.
According to the authorities, more than 70 places in the city were flooded on Tuesday, including Sao Paulo General Warehousing and Centers Company (Ceagesp), the largest food distribution center in Brazil. Over 70 tons of food products were destroyed in the flood, causing a loss of 15 million reais (8.47 million U.S. dollars).
