World Weather Attribution Services claimed that the rain that hit Wayanad on July 30 was the heaviest and the third-heaviest ever recorded in the region. It had overcome the fury of the 2018 floods in the state.

According to studies, it was found that on July 30, when landslides occurred in Mundakkai, Chooralmala and Attamalai areas of Wayanad, there was an extreme burst of 140 mm of rain in a single day. From July 22 onwards, the region has witnessed almost continuous rainfall with some areas even recording more than 1.8 meters of rain in a month.

Scientists and researchers from Norway, India, Malaysia, the United States, Sweden and the Netherlands have reported that rainfall intensity has increased by 17 percent over the past 45 years. They have also predicted that extreme single-day rainfall in Kerala could become 4 percent more intense and even lead to even more catastrophic landslides.
