The India Meteorological Department (IMD) has issued a yellow alert for parts of Kerala as the state braces for heavy rainfall over the next two days. Several districts have been warned of potential downpours, likely triggering waterlogging, rough seas and disruption to daily life.

Rain forecast and alert details

According to the latest IMD bulletin, rainfall of 7 cm to 11 cm in a 24-hour period is likely at one or two places in Kerala between November 25 and 27
Districts under the yellow alert include Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, Idukki and Ernakulam, where isolated heavy showers, thunderstorms and gusty winds are expected.

The IMD has also forecast squally weather along the coast, with wind speeds expected to range between 35–45 km/h, gusting up to 55 km/h — conditions that could make sea travel risky for fishermen and coastal communities.

Cause: Low pressure and active monsoon revival

Meteorologists say the rainfall surge is linked to a low-pressure area forming over the Comorin region and adjoining parts of the southwest Bay of Bengal, which is influencing moisture flow over Kerala. This system, combined with an active northeast monsoon, is responsible for the heavy showers expected in coastal and low-lying districts.

The IMD’s all-India summary issued on Tuesday also flagged heavy rainfall over Kerala and Mahe for November 25–26, along with thunderstorm warnings in several coastal and central districts.

Likely impacts: Flooding, waterlogging and sea hazards

Officials have warned of temporary waterlogging, especially in low-lying urban zones and poor visibility on roads during heavy showers. High winds may cause tree-fall or uprooting, posing risks to power lines and houses.

Coastal districts are on alert for rough seas, strong winds and high waves — fishermen and maritime workers have been advised to avoid venturing into open seas until conditions stabilise.

There is also concern over inland flooding in districts with high rainfall and rivers close to flood levels — especially low-lying paddy fields and residential areas around backwaters and canals.

Precautionary advisories issued

  • Authorities have urged people to avoid unnecessary travel during heavy rain and thunderstorms.
  • Coastal residents and fishermen have been told not to venture into the sea until further notice.
  • The public is advised to monitor weather updates, follow advisories issued by district disaster management authorities and take shelter indoors during strong winds or lightning.

Local administrations in vulnerable districts have also been asked to prepare disaster-response teams and keep drainage systems and water pumps ready.

What could worsen the situation?

Weather experts caution that prolonged rainfall combined with gusty winds and high sea waves can escalate the situation, especially in regions already waterlogged or prone to flooding. Urban low-lying areas, backwater zones and coastal hamlets are particularly at risk.

If the low-pressure area intensifies or moves slowly, some districts may receive continuous heavy rainfall over 24–48 hours, which could lead to flash floods or inundation. The IMD has urged residents to remain alert for any update.

Conclusion

As Kerala braces for a renewed spell of heavy rain, the next 48 hours are likely to test the readiness of both citizens and local administrations. With the IMD’s yellow alert in force and weather conditions remaining volatile, residents are urged to stay cautious and take all necessary precautions. Adequate preparedness and timely response will be key to minimising impact and ensuring safety
