Thiruvananthapuram: The India Meteorological Department (IMD) has issued a yellow alert for seven districts in Kerala on Monday, October 26, 2026, forecasting isolated heavy rainfall. The warning covers Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, Idukki and Ernakulam.
Kerala's weather forecast has been revised, with the India Meteorological Department (IMD) indicating a weakening of rainfall activity across the state. The orange alert for isolated very heavy rainfall in four districts — Pathanamthitta, Idukki, Palakkad and Malappuram — has been withdrawn, according to the revised warning.

According to the Kerala State Disaster Management Authority (KSDMA), the alert comes amid a forecast of continued rainfall across the state over the next five days.

Heavy rainfall is defined by the IMD as precipitation between 64.5 mm and 115.5 mm within 24 hours. Residents, particularly those in hilly and coastal areas, have been advised to remain vigilant.

Kerala weather forecast: Rain to continue over the next five days

The IMD has forecast widespread rainfall across Kerala, Mahe and Lakshadweep on October 26 and 27. Isolated places in Kerala may also receive very heavy rainfall, according to the forecast provided in the report.

Strong winds are possible in Kerala, Mahe and Lakshadweep, with speeds potentially reaching 50 km/h in some areas. Residents have been advised to follow official weather updates and local authorities' instructions.

Tamil Nadu, Andhra Pradesh and Telangana weather alerts

Rain and thunderstorms are also expected in other southern states.

Tamil Nadu, Puducherry and Karaikal: Widespread rainfall is forecast on October 26, with thunderstorms and winds of 40–50 km/h possible on October 26 and 27.

Coastal Andhra Pradesh: Thunderstorms and strong winds are forecast on October 26 and 29. Isolated areas of Coastal Andhra Pradesh and Yanam could experience heavy rainfall on October 27 and 28.

  • Telangana: Thunderstorms are possible on October 28, with isolated heavy rainfall also forecast.
  • Rayalaseema: Thunderstorms are likely between October 26 and 28.
  • Karnataka: Coastal Karnataka may receive rain from October 27 to 31, while North Interior Karnataka could experience rainfall from October 29 to 31.

What does a yellow alert mean?

An IMD yellow alert indicates that people should remain aware of potentially adverse weather conditions and monitor official updates. Heavy rainfall can cause localised waterlogging, traffic disruption and difficulties in vulnerable areas.

People living near slopes, streams and other landslide-prone locations should exercise caution during periods of intense rainfall. Residents should also avoid flooded roads and follow instructions issued by local disaster management authorities.

The latest forecast points to a period of unsettled weather across southern India, with Kerala facing isolated heavy rainfall and neighbouring states also expecting thunderstorms and strong winds.

The combination of heavy rain and gusty winds could affect road travel, coastal activities and everyday movement. Hilly areas may be particularly vulnerable to landslides, while low-lying urban locations could experience waterlogging.

The supplied report also refers to a developing weather system in the Bay of Bengal and claims that it has intensified into a cyclone named 'Arnab'. However, this cyclone claim has not been independently verified here and should not be presented as confirmed without an official IMD bulletin. Residents should rely on the latest IMD and KSDMA advisories for updates on the system's status and projected movement.
