Kerala is bracing for an escalation of its ongoing heavy rainfall, as a new low-pressure area has formed over the Bay of Bengal. This system, which emerged over the southeast Bay of Bengal on Tuesday, October 21, 2025, is projected to intensify further into a depression within the next 24 hours, settling over the central and west-central parts of the southern Bay.
This developing weather phenomenon is expected to unleash significant rainfall, ranging from heavy to very heavy, across the state, with the Ghat regions identified as particularly susceptible to extreme downpours. The India Meteorological Department (IMD) has responded by issuing an ‘orange alert’ for five districts: Idukki, Ernakulam, Thrissur, Palakkad, and Malappuram, signaling the likelihood of very heavy rains. A ‘yellow alert’ is in place for all other districts, indicating potential isolated heavy rainfall.
Red Alert Declared for Wednesday
Looking ahead, a more severe ‘red alert’ has been announced for Idukki, Palakkad, and Malappuram for Wednesday, warning of extremely heavy rainfall. Concurrently, Pathanamthitta, Alappuzha, Kottayam, Ernakulam, Thrissur, Kozhikode, and Wayanad districts will be under an ‘orange alert’, while the remaining areas will continue under a ‘yellow alert’ for Wednesday.
Meanwhile, an existing weather system over the Arabian Sea, despite intensifying recently, is gradually moving away from the Kerala coast, offering a slight reprieve from that front.
In the preceding 24-hour period, ending at 8:30 a.m. on Tuesday, Neyyattinkara in Thiruvananthapuram district recorded the highest rainfall at 11 cm. Other notable rainfall figures include Quilandi in Kozhikode with 9 cm, and 7 cm each in Piravom (Ernakulam), Irinjalakuda (Thrissur), Thattathumala (Thiruvananthapuram), and Kunnamangalam (Kozhikode).
