Monsoon Intensifies: Yellow Alert Issued for 9 Districts on August 27

Rapid Summary

• Monsoon Forecast: North and central Kerala will experience active monsoon conditions due to a low-pressure area over the Bay of Bengal. Heavy rainfall is expected during the remaining days of August.
• Affected Areas: A yellow alert has been issued for nine districts-Kasaragod, Kannur, Wayanad, Kozhikode, Malappuram, Palakkad, Thrissur, Ernakulam, and Idukki. Rainfall is likely to range between 64.5 mm to 115.5 mm in these areas on Wednesday.
• Weather system Movement: The low-pressure system over the Bay of Bengal is predicted to move west-northwestwards and intensify further in the next two days before weakening by September.
• Rainfall Deficit: Kerala currently faces a 15% shortfall in rainfall this southwest monsoon season but expects partial recovery from increased activity at month’s end. The State has received 1,430 mm of rain against an average of 1,691.7 mm as of August 26.

Indian Opinion Analysis

The formation of a low-pressure system over the Bay of Bengal brings hope for north and central Kerala as heavy rainfall may partially offset the state’s seasonal monsoon deficit (currently at -15%). While this surge may stabilize water availability and assist agricultural activities reliant on monsoon rains in core regions like Idukki or Wayanad, it also calls attention to preparedness measures such as ensuring drainage systems are operational across urban centers like Kozhikode or Ernakulam under yellow alert conditions.

Long-term implications include understanding shifts in regional weather patterns-such as weakened westerlies-which could further challenge consistent seasonal rainfalls critical for Kerala’s agrarian economy and hydropower generation capacity statewide.
