Rescue workers on Wednesday searched for any remaining survivors among mud and wreckage after devastating flash floods and landslides hit the picturesque Brazilian city of Petropolis, killing at least 94 people.

Streets were turned into torrential rivers and houses swept away Tuesday when heavy storms dumped a month’s worth of rain in three hours on the scenic tourist town in the hills north of Rio de Janeiro.

With 35 people still reported missing, fears that the death toll could climb further sent firefighters and volunteers scrambling through the remains of houses washed away in torrents of mud, many of them in impoverished hillside slums.

It is the latest in a series of deadly storms to hit Brazil in the past three months, which experts say are being made worse by climate change.

The state government said at least 24 people had been rescued alive, as it reported the latest death toll on Wednesday evening.

Around 300 people were being housed in shelters, mostly in schools, officials said. Charities called for donations of mattresses, food, water, clothing and face masks for victims.
