Kerala Heavy Rainfall Update October 2025 | Red Alert in Idukki, Palakkad & Malappuram | IMD Weather Report

Kerala Under Heavy Rainfall: Red, Orange, and Yellow Alerts Issued Across the State | October 2025 Update

Kerala, known for its lush green landscapes and monsoon beauty, is currently facing one of the heaviest spells of rainfall this season. The India Meteorological Department (IMD) has sounded multiple alerts—Red, Orange, and Yellow—across several districts, warning residents of severe downpours, flooding, and possible landslides. As the rain continues to batter the state, authorities and citizens are on high alert to prevent a repeat of past flood-like situations.

Current Situation

According to the IMD’s latest bulletin, Red Alert—the highest level of warning—has been issued for Idukki, Palakkad, and Malappuram districts. This alert signifies the possibility of extremely heavy rainfall, exceeding 204 mm in 24 hours.

Meanwhile, Orange Alerts have been issued for other districts such as Ernakulam, Thrissur, Kozhikode, and Kottayam, indicating very heavy rain likely between 115 mm and 204 mm.

A Yellow Alert is in place across Thiruvananthapuram, Pathanamthitta, and Alappuzha, suggesting heavy but not extreme rainfall.

The situation is especially tense in high-range areas like Idukki, where continuous downpours have raised fears of landslides. Low-lying regions in Ernakulam, Thrissur, and Palakkad have also reported waterlogging and minor flooding due to overflowing drains and rivers.

Cause of the Heavy Rainfall

Meteorologists attribute the ongoing heavy rainfall to a low-pressure area that has formed over the southeast Arabian Sea, close to the Lakshadweep region. This system is pulling in moist southwesterly winds, intensifying cloud formation over Kerala and leading to widespread rain.

In addition to this, upper air cyclonic circulation over the southern part of the peninsula is further enhancing the rainfall intensity. The combination of these two weather systems has caused a continuous spell of rain, especially in the central and northern parts of Kerala.

Impact on Daily Life

The relentless rain has started to affect normal life in many districts:

• Transportation Disruptions: Several roads, particularly in the high ranges and along riverbanks, have become impassable due to flooding and landslides. In Thiruvananthapuram, parts of the Thenkasi road have been closed due to fallen trees and debris.

• School and Office Closures: Educational institutions in districts under Red and Orange alerts have been instructed to remain closed as a precautionary measure.

• Power and Communication Lines: In some areas, strong winds accompanying the rain have damaged electric poles and disrupted mobile networks.

• Waterlogging in Urban Areas: Cities like Kochi, Kozhikode, and Thrissur have reported heavy waterlogging, affecting local transportation and businesses.

Rising Water Levels and Dam Management

Authorities have closely monitored Kerala’s dams and reservoirs as water levels rise steadily due to the continuous rain. The Mullaperiyar Dam in Idukki, one of the state’s key reservoirs, has had all 13 shutters opened to maintain safe water levels. This has led to controlled water release into downstream areas, prompting flood alerts in nearby localities.

Other major dams like Idukki, Idamalayar, and Kakki are also being monitored round the clock. The Kerala State Disaster Management Authority (KSDMA) has advised residents living downstream of major rivers to remain vigilant and follow evacuation orders if issued.

Landslide and Flood Risk

One of the biggest threats during Kerala’s heavy rain spells is the risk of landslides in hilly regions. Districts such as Idukki, Wayanad, and Malappuram have already experienced minor landslips. Continuous rain has saturated the soil, making slopes unstable and increasing the risk of major landslides.

Flooding is another growing concern. The Periyar, Bharathapuzha, and Pamba rivers are all flowing close to danger levels. Low-lying and riverbank villages have been advised to move to higher ground or temporary shelters.

Government and Disaster Response

The Kerala government has activated emergency control rooms in all districts. Teams from the National Disaster Response Force (NDRF) and State Fire & Rescue Services are on standby in Idukki, Malappuram, and Thrissur for immediate rescue operations if needed.

Local self-government bodies are also ensuring that relief camps are ready to accommodate people in case of evacuation. Food, medical supplies, and emergency kits have been stocked in vulnerable areas.

Fishermen have been advised not to venture into the sea, as the IMD has warned of rough conditions and strong winds along the Kerala coast.

Public Safety Measures

Authorities have urged citizens to take the following precautions:

1. Avoid unnecessary travel, especially in districts under Red or Orange alerts.

2. Stay away from riverbanks, flooded areas, and unstable slopes.

3. Keep emergency kits, drinking water, and essential medicines ready.

4. Turn off electrical appliances and gas connections if your area is prone to flooding.

5. Follow official advisories from the IMD and KSDMA rather than social media rumors.

6. Keep emergency helpline numbers handy: 1077 (District Control Room) and 112 (National Helpline).

Forecast for the Next Few Days

According to IMD forecasts, the heavy rainfall is likely to continue for the next three to five days, with intensity gradually reducing afterward. The low-pressure system over the Arabian Sea is expected to weaken, but isolated heavy rain may persist in some northern districts.

The IMD has suggested that the monsoon withdrawal from Kerala could be delayed this year, as the state continues to experience moisture-laden winds and unstable weather patterns.

Conclusion

Kerala’s ongoing heavy rainfall has once again highlighted the state’s vulnerability to extreme monsoon events. While the government’s proactive measures and timely IMD alerts have helped minimize damage so far, continuous monitoring and public cooperation remain essential.

As rescue teams stay on alert and citizens brace for more rain, Kerala stands united—weathering yet another testing monsoon season with resilience and preparedness.
