REPUBLIKA.CO.ID, JAKARTA -- As many as 1,637 families were displaced by flash floods that hit Sumbawa, West Nusa Tenggara, on Friday due to incessant heavy rain.

Head of the Data and Information Center of the National Disaster Mitigation Agency (BNPB) Sutopo Purwo Nugroho said here on Saturday that continuous, torrential rainfall the last three days led to the flash floods in Sumbawa district.

"Low pressure near Australia caused a lot of air mass to be drawn to that region. As a result, East Java, Bali and Nusa Tenggara experienced torrential rains the last three days," Nugroho stated in a broadcast message.

On Friday (February 20) night, flash floods hit the four villages of Labuan Jambu, Labuan Pidang, Banda and Batu Lanteh in Sumbawa, causing 1,637 families to flee.
