The weather department has also forecast squally weather, with wind speeds reaching 45-55 kmph, gusting to 65 kmph over Kerala until September 11.

It may be recalled that heavy rain in the Wayanad district led to huge landslides on July 30 causing death and destruction.

The World Weather Attribution services stated that the rain that had lashed Wayanad on July 30 was the heaviest and the third heaviest on record in the region. It had surpassed the fury of the floods of 2018 in the state.

According to studies, it was found that on July 30 when landslides struck in the Mundakkai, Chooralmala and Attamalai areas of Wayanad, there was an extreme burst of 140 mm of rainfalls in a single day. From July 22 onwards, the region has been witnessing nearly continuous rainfall and some areas even recorded over 1.8 metres of rain in one month.

Scientists and researchers from Norway, India, Malaysia, the US, Sweden and the Netherlands have reported that the intensity of rain has become 17per cent heavier in the last 45 years. They have also predicted that extreme single-day bursts of rainfall in Kerala could become a further 4 per cent heavier and can even lead to even more catastrophic landslides.
