Over 30,000 people have been displaced by heavy rains in southeast Brazil that also killed 54 people and left 18 missing. The storms in recent days caused floods and landslides, submerging entire neighbourhoods and sending homes tumbling down hillsides in the states of Minas Gerais, Espirito Santo and Rio de Janeiro.

Rains subsided by Monday, but were expected to resume later this week in some areas. Flooded roads created violent rapids, sweeping up victims, cars and other debris.

Those evacuated were being housed in makeshift shelters in churches, schools and fire stations. Local authorities have asked for donations of clothes, sheets and mattresses for the victims.

In Minas Gerais, 15,000 people were evacuated and in Espirito Santo nearly 10,000 more, according to local rescue efforts. In Rio, at least 6000 were evacuated, according to local news media, citing figures from various municipalities. Rio state authorities didn't immediately respond to a request for official data.

Local authorities warned that the Belo Horizonte metropolitan area, home to nearly 6 million people, could see up to 100 millimeters of rain in the next three days.

The city had 171 millimeters over one 24-hour period from Thursday to Friday, the highest rainfall in 110 years. Over 120 municipalities in Minas Gerais state have declared a state of emergency.
