Heavy rains continued to trigger floods and landslides in February and March, but on a smaller scale. Over 67,000 people were affected, with 22 killed or missing. Over 10,000 houses were damaged. (OCHA, 31 Mar 2013).
Although Indonesia started transitioning from the wet season to the dry season in April, there was an increase in temperature of Indonesian sea water causing more frequent and more intense rainfall, prolonging a wet season already characterized by heavy rainfall and flooding. Floods, landslides and whirlwinds were the cause of 117 casualties and affected over 220,000 people in April and May. (OCHA, 31 May 2013)
