Multiple districts across Kerala have been placed under a yellow alert as sustained rainfall continues to impact the state, prompting advisories for residents and local administrations to prepare for potential flooding and disruptions. The warning, issued for Sunday, covers Thiruvananthapuram, Kollam, Pathanamthitta, Kottayam and Idukki, amid forecasts of moderate to heavy precipitation over the coming days.
The alert follows the formation of a low-pressure system over the southwest Bay of Bengal and the adjoining equatorial Indian Ocean, which is influencing widespread rain activity across southern India. Meteorological officials indicated that rainfall intensity may remain elevated for at least the next 48 hours, with isolated heavy spells possible in hilly and midland regions.A yellow alert signals the likelihood of heavy rainfall between 64.5 mm and 115.5 mm within 24 hours, requiring authorities to remain vigilant. While it is not the highest category of warning, the classification calls for preparedness measures in districts prone to waterlogging, landslides and river swelling.
Urban centres, including Kochi, have already recorded intermittent showers that have slowed traffic and strained drainage systems in low-lying neighbourhoods. Civic officials said emergency response teams and disaster management units have been placed on standby, particularly in districts with a history of monsoon-related disruptions.Idukki and Pathanamthitta, which contain large tracts of ecologically sensitive terrain, remain under particular watch due to landslide vulnerability. In previous monsoon seasons, intense rainfall in these regions has resulted in road blockages, slope failures and displacement of residents in hillside settlements.
Urban planners note that Kerala’s dense settlement patterns and ageing drainage networks heighten flood risk during sustained rain events. Expanding impermeable surfaces in growing towns further reduces natural water absorption, amplifying runoff during peak rainfall periods. Climate researchers have also observed that extreme rain episodes are becoming more frequent along India’s western coast, underlining the need for adaptive urban design and watershed management.Transport authorities have advised commuters to monitor official bulletins before travelling, especially in high-altitude districts. Fisherfolk along the southern coast have also been cautioned against venturing into rough seas if wind conditions intensify.
Local administrations are reviewing reservoir levels and coordinating with state disaster response teams to ensure timely communication in case of escalation. Relief shelters remain on standby should evacuation become necessary in vulnerable pockets.Weather officials expect rainfall to taper gradually if the low-pressure system weakens or shifts direction. Until then, residents across the five districts are urged to remain cautious, secure loose materials, avoid waterlogged roads and stay informed through official updates.As Kerala navigates another spell of heavy rainfall, the episode underscores the increasing importance of resilient infrastructure, early warning systems and climate-responsive urban planning in safeguarding communities across the state.
