Although the dry season typically runs from June to September for most of Indonesia, several provinces in the eastern half of the country experienced heavy rains in June 2012 due in part to the effect of tropical cyclone Guchol occurring in the southwest Pacific. The rains caused rivers to swell and burst their banks, resulting in flooding of adjacent crop fields and houses. In addition to floods, the unseasonal rains also caused major landslides. In total, 975 people were affected. (OCHA, 30 Jun 2012)
In July, floods, landslides and whirlwinds affected over 4,000 people, as heavy and continuous rains intensified towards the end of the month (OCHA, 31 Jul 2012).
