Flooding and landslides in central Java have killed at least 35 people, while 25 others are missing on the Indonesia island.
The heavy rains have impacted thousands of homes, with many of the structures under water.
The rains have also triggered landslides, sweeping cars and people off streets and burying people in their homes.
Rescue workers are looking for survivors on Java, the southernmost of the county's main islands and home to the capital, Jakarta.
Flooding and landslides are common occurrences in Indonesia; a vast, tropical, disaster-prone archipelago home to more than 250 million people. Java is the world's most populous island.
