Understanding Kerala’s Monsoon Pattern
Kerala receives a meaningful portion of its annual rainfall during the southwest Monsoon, which typically lasts from June to September. The state’s geography,nestled between the Arabian Sea and the Western Ghats,makes it particularly vulnerable to heavy rainfall events. In recent years, Kerala has experienced an increase in extreme weather events, highlighting the importance of preparedness and early warning systems. Learn more about Kerala’s geography and climate.

## Summary of Kerala Weather warnings & Cyclone Thane Threat (September 27th, 2025)
Kerala Weather Alert: Heavy Rainfall Warnings issued for 7 Districts & shift from Distress to Threat to Thane
Published: 2025/09/25 14:08:47 | Author: James Carter | Website: archyde.com
Current Rainfall Situation in kerala – September 2025
Kerala is bracing for intense rainfall, with the India Meteorological Department (IMD) issuing heavy rainfall alerts for seven districts as of today, September 25th, 2025.The affected areas are: Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, Idukki, and Ernakulam. This follows a period of relatively calmer monsoon conditions, making the sudden intensification a cause for concern. The primary driver is a low-pressure system forming in the Arabian Sea, coupled with a strengthening of the southwest monsoon currents. Kerala monsoon updates are being closely monitored by state disaster management authorities.
District-Specific Rainfall Warnings (September 25-27, 2025)
Here’s a breakdown of the warnings issued, categorized by district:
* Thiruvananthapuram & Kollam: Orange Alert – Expect isolated heavy to very heavy rainfall (115.6 mm to 204.4 mm in 24 hours). Potential for localized flooding and disruptions to traffic.
* Pathanamthitta, Alappuzha & Kottayam: Red Alert – Extremely heavy rainfall (204.5 mm or more in 24 hours) is highly likely. Significant risk of widespread flooding, landslides, and damage to infrastructure.
* Idukki & Ernakulam: Yellow Alert – Heavy rainfall (64.5 mm to 115.5 mm in 24 hours) is anticipated. Be prepared for potential disruptions and exercise caution. Idukki dam water levels are being particularly monitored.
Thes alerts are valid through September 27th, 2025, and are subject to change based on evolving weather conditions. Stay updated with the latest Kerala weather forecast from official sources.
Thane Cyclone – A shifting Threat Landscape
While the immediate concern is the heavy rainfall, meteorological agencies are also tracking a developing cyclonic circulation in the Bay of Bengal, currently designated as ‘Thane’.Initially, the system posed a distress situation, potentially weakening before landfall. However, recent projections indicate a shift – the system is now strengthening and is considered a potential cyclone threat to Kerala.
From Distress to Threat: What Changed?
Several factors contributed to this change:
- Sea Surface Temperatures: Higher-than-normal sea surface temperatures in the Bay of Bengal are providing ample energy for the system to intensify.
- upper-Level Divergence: Favorable upper-level divergence is aiding in the outflow of air, allowing the cyclone to organize and strengthen.
- Wind Shear: reduced vertical wind shear is allowing the cyclone to maintain its structure.
The IMD now predicts a possible landfall near the Kerala-Karnataka coast around September 28th, 2025. This means the heavy rainfall currently impacting Kerala could be exacerbated by strong winds and storm surges if ‘Thane’ makes landfall as predicted. Cyclone Thane updates are crucial for coastal residents.
impact Assessment & Potential Risks
The combined effect of the heavy rainfall and the potential cyclone poses significant risks:
* flooding: Low-lying areas are particularly vulnerable to flooding. River banks are likely to overflow.
* Landslides: Steep slopes in the Western Ghats are prone to landslides,especially in Idukki,Wayanad,and Pathanamthitta.
* Infrastructure Damage: Roads, bridges, and power lines could be damaged, disrupting transportation and interaction.
* Coastal erosion: Strong winds and storm surges associated with ‘Thane’ could cause significant coastal erosion.
* Disruption to Agriculture: Heavy rainfall can damage crops and led to agricultural losses. Kerala agriculture damage assessment teams are on standby.
safety Measures & Preparedness – What You Need to Do
The Kerala State Disaster Management authority (KSDMA) has issued the following guidelines:
- Stay Informed: Regularly check for updates from the IMD and KSDMA. Utilize mobile apps providing live weather alerts Kerala.
- Evacuate if Necessary: If you live in a vulnerable area, be prepared to evacuate to a safe shelter. Follow instructions from local authorities.
- Secure Your Property: Secure loose objects that could be blown away by strong winds. Reinforce roofs and windows.
- Stock Up on Essentials: keep a supply of food, water, medicines, and other essential items.
- avoid Travel: Avoid unneeded travel, especially in affected areas.
- Emergency Contact Numbers: Keep a list of emergency contact numbers handy. (KSDMA Control Room: +91-471-2363222, Toll-Free: 1800-212-3222)
