Torrential rains have killed at least 15 people in the outskirts of Sao Paulo, Brazil, rescuers said on Friday.
The disaster comes after two years of drought which caused serious water shortages in the country.
Thirteen people were swept away by landslides while two more drowned in the flooding.
So far, eight people have been reported as missing.
Rescue official Marcos Palumbo said they could be trapped in two homes that collapsed in Mairipora.
Rescuers tried to help stranded people while local TV showed homes and cars sink into water.
Many families are reported stranded in many communities in the greater Sao Paulo metropolitan area.
The heavy rains also shut down the Sao Paulo international airport for six hours.
The commuter rail network was also halted by the flooding.
