Monsoon Intensifies in Kerala; Orange Alert Issued for Seven Districts Amid Heavy Rains
Monsoon rains have strengthened across Kerala, leading to flooding in parts of Ernakulam, Idukki, and Thrissur districts. The India Meteorological Department (IMD) issued an orange alert, signifying very heavy rainfall (11 cm to 20 cm), for seven districts: Kollam, Pathanamthitta, Alappuzha, Kottayam, Idukki, Ernakulam, and Thrissur. Continuous rains in Wayanad caused the Chooralmala River to swell, eroding its banks near a Bailey bridge.
Unpacked:
Kerala has experienced significant floods in the past, including the catastrophic 2018 floods and the historic 1924 'Great flood of 99.' While this year’s rainfall is severe, past disasters have resulted in hundreds of deaths and extensive landslides, especially in districts like Idukki. The severity and frequency of floods have raised concerns about changing climate patterns.
An 'orange alert' from the India Meteorological Department signals the likelihood of very heavy rainfall (11 cm to 20 cm in 24 hours). It urges authorities and the public to prepare for possible flooding, disruptions, and to remain vigilant for warnings or evacuation notices.
Climate change has intensified monsoon downpours in Kerala, making extreme rainfall events more frequent and severe. Studies indicate that human-caused climate change increased the intensity of a recent monsoon downpour by 10%, contributing to deadly landslides and flooding, especially in vulnerable areas like Wayanad.
Residents in affected districts face risks such as flash floods, riverbank erosion, landslides, infrastructure damage, and possible displacement. Swollen rivers, like the Chooralmala in Wayanad, threaten bridges and roads, potentially isolating communities and complicating rescue or relief efforts.
