flash flood

Officials estimate that landslides and flash floods in the country have killed around 60 people over the past week.

"Extraordinary danger. Flooding and flash floods may occur. Follow the advice of civil protection," the agency wrote on X.

A late summer monsoon that swept over Southern California last week, triggering mudslides and flash floods also destroyed multiple homes and led to a child’s death, officials said.

Those storms could create fires from dry-lightning strikes or flash floods and debris flows depending on how strong they turn out to be, the National Weather Service warned.

Landslides and flash floods are not uncommon across the Indonesian archipelago especially during the rainy season and climate change has made the situation worse, officials say.
