Kerala weather update: IMD issues yellow alert for 7 districts as Bay of Bengal systems form

IMD issues alerts across southern and central Kerala

The India Meteorological Department (IMD) has issued a yellow alert for seven districts across Kerala as a combination of weather systems in the Arabian Sea and the Bay of Bengal brings widespread rain, thunderstorms and gusty winds to the state.

The alert covers districts extending from Thiruvananthapuram in the south up to Ernakulam, where isolated heavy rainfall is expected over the next 24 hours. Weather officials indicated that while the immediate low-pressure formations are moving away or developing off the coast, their influence on regional wind and moisture patterns will sustain heavy precipitation across Kerala for at least four days.

Twin Bay of Bengal systems drive rainfall

According to weather bulletins released by the IMD, a well-marked low-pressure area over the southwest Arabian Sea continues to move west-northwestwards away from the Kerala coast. However, its associated cyclonic circulation is still pulling moisture into the peninsula, sparking localized downpours.

Simultaneously, meteorologists are tracking two consecutive low-pressure developments in the Bay of Bengal. The first system is expected to coalesce within 24 hours, followed closely by a second system around 23 October.

Although these Bay of Bengal systems are not projected to make direct landfall on the Kerala coast, their development is significantly altering wind flows and moisture levels across southern India.

State preparedness and early warnings

India's proactive weather forecasting infrastructure and early warning network, led by the IMD, have enabled state authorities to prepare early for potential urban waterlogging and localized disruptions. District administrations from Thiruvananthapuram to Ernakulam have activated emergency monitoring cells to assist residents in vulnerable coastal and hilly regions.

Fisherfolks and residents near riverbanks have been advised to remain cautious, particularly given the likelihood of sudden lightning strikes and strong wind gusts during afternoon and evening hours.
