Although the southwest monsoon has officially withdrawn from India, unsettled weather conditions are expected to persist across several regions. Southern India, in particular, is bracing for a fresh wave of intense rainfall as the northeast monsoon intensifies. The India Meteorological Department (IMD) issued a forecast on October 16, 2026, warning of heavy to very heavy rain, thunderstorms, and strong winds in various states.
heavy rainfall alert: Southern States on High Alert
The IMD has issued an orange alert for Tamil Nadu, Puducherry, and South Interior Karnataka, where rainfall is expected to be particularly heavy, potentially ranging from 115.6 mm to 204.4 mm. These regions remain the primary focus of current weather warnings due to the influence of active weather systems.
Additionally, a yellow alert has been issued for parts of Andhra Pradesh, Coastal Karnataka, Kerala, and Mahe. These areas may experience significant rainfall, with estimates ranging between 64.5 mm and 115.5 mm. Residents in these regions should prepare for potential disruptions caused by heavy downpours.
Flash Floods and Waterlogging Risks
Persistent and intense rainfall increases the risk of flash floods and waterlogging in vulnerable areas. In Tamil Nadu, districts such as Erode, Nilgiris, Theni, Villupuram, and Cuddalore have been identified as high-risk zones. Similarly, Ernakulam and Palakkad in Kerala, along with Kodagu and Chikkamagaluru in Karnataka, are closely monitored for flood risks over the next 24 hours.
Authorities have urged residents in low-lying areas to remain vigilant, keep track of local weather updates, and avoid approaching swollen rivers, streams, or drainage channels. Commuters are advised to exercise extreme caution on roads that may become waterlogged.
What This Means for Farmers
The ongoing weather instability poses significant challenges for agricultural operations in the affected southern states. Farmers should take immediate steps to mitigate potential damage:
- Field Drainage: Ensure that all fields have adequate drainage systems to prevent waterlogging, which can damage standing crops.
- Postpone Farm Operations: Delay the application of pesticides and fertilizers until weather conditions stabilize to ensure effectiveness and prevent runoff.
- Protect Harvests: Take proactive measures to protect already harvested crops from rain and strong winds. Secure storage areas and cover produce to prevent spoilage.
- Monitor Advisories: Stay updated with the latest IMD forecasts and local agricultural department advisories to make informed decisions regarding farm management during this period of unsettled weather.
While southern India faces heavy rain, other parts of the country, including Delhi-NCR, are experiencing cloudy skies, gusty winds reaching 40–50 kmph, and isolated light showers. Despite the widespread rain warnings in the south, some regions continue to report unusually warm and humid conditions, highlighting the complex weather patterns currently affecting the country.
