The India Meteorological Department (IMD) issued a ‘yellow’ alert on May 29, 2026, warning of heavy monsoon showers across six districts in Kerala. The alert targets Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, and Ernakulam. It follows an early advancement of the southwest monsoon. The region is experiencing isolated, intense downpours fueled by a active cyclonic circulation over the Arabian Sea. The weather agency has advised regional authorities and residents to maintain strict vigilance.
The affected southern and central districts are bracing for isolated heavy rainfall ranging between 64.5 mm and 115.5 mm within a 24-hour window. According to meteorologists, the intense wet spell is expected to persist across the state for the next few days. Alongside the heavy downpours, the weather department has warned of thunderstorms, lightning, and gusty winds reaching speeds of 30 to 40 kmph.
The primary concern for urban and low-lying areas remains significant waterlogging and flash floods. Major thoroughfares are expected to experience severe traffic congestion due to reduced visibility and flooded streets. Furthermore, disaster management teams have placed hilly terrains on high alert for potential landslides and mudslides. Strong winds also pose a threat to infrastructure, with officials warning of possible uprooted trees, power outages, and partial damage to vulnerable structures.
Concurrently, a separate coastal hazard warning has been issued. The National Centre for Ocean Information Services (INCOIS) highlighted the risk of sea incursions along the Kerala coast due to the ‘Kallakkadal’ (swell surge) phenomenon. High waves ranging from 0.8 to 1.6 meters are anticipated, prompting a strict advisory for fishermen and coastal residents to avoid venturing into the rough seas.
In response to the deteriorating weather conditions, state authorities have ramped up precautionary measures. Residents living in landslide-prone and low-lying areas are advised to relocate to safer zones if directed by local administrators. The general public has also been urged to avoid non-essential travel until weather conditions stabilize.
