Kerala weather today: IMD issues yellow alert, thunderstorms & heatwave to hit multiple districts

Light to moderate rain across Kerala on Tuesday brought relief from intense summer heat, but the India Meteorological Department (IMD) has warned that thunderstorms, strong winds, and high temperatures will continue to affect several parts of the state.

In its latest Kerala weather update, the IMD said thunderstorms with moderate rainfall and gusty winds reaching up to 50 kmph are likely in isolated areas of Thiruvananthapuram, Kollam, Pathanamthitta, Ernakulam, and Thrissur districts. These areas have been placed under an orange alert for the next few hours.

A yellow alert has been issued for Alappuzha, Kottayam, Idukki, Palakkad, Malappuram, Kozhikode, Wayanad, Kannur, and Kasaragod districts, where light rainfall accompanied by winds of up to 40 kmph is expected. Residents have been advised to remain cautious due to the possibility of lightning and sudden weather changes.

According to the IMD’s five-day Kerala rain forecast, all 14 districts are likely to receive light to moderate rainfall in the coming days, with isolated heavy rainfall in select regions. Kannur and Kasaragod are expected to see heavier showers on April 30, followed by Pathanamthitta, Idukki, and Wayanad on May 1.

On May 2, Alappuzha, Kottayam, and Ernakulam districts may receive moderate to heavy rainfall.

Despite the rain activity, a heatwave-like situation continues across parts of Kerala. The IMD has issued a yellow alert for high temperatures, with Palakkad likely to record maximum temperatures of up to 40°C.

Kollam and Kozhikode may see temperatures around 38°C, while several districts including Pathanamthitta, Alappuzha, Kottayam, Ernakulam, Thrissur, Malappuram, Kannur, and Kasaragod are expected to experience highs near 37°C. Thiruvananthapuram is likely to record around 36°C.

Meteorologists noted that temperatures remain 3–4°C above normal, and combined with high humidity, this is expected to result in hot and uncomfortable conditions, especially in non-hilly areas. The mix of rainfall and heat is typical of Kerala’s pre-monsoon weather pattern, often marked by sudden showers followed by humid conditions.

Authorities have urged people to stay updated with the latest IMD weather alerts, avoid open areas during thunderstorms, and take precautions against heat exposure.

While the rain has offered temporary relief, fluctuating weather conditions are expected to continue across Kerala over the next few days.
