Thunderstorms are expected across parts of Kerala today, September 16. The India Meteorological Department warns of gusty winds reaching 40–50 kmph and isolated heavy rain. Morning advisories placed Pathanamthitta, Idukki and Ernakulam on watch. Later updates highlighted Idukki, Kozhikode, Wayanad and Kannur. Expect short, intense cells as convective clouds build from afternoon into evening. Further pulses are signalled on September 19 to 21.
IMD’s heavy rainfall category denotes 7–11 centimetres in 24 hours. With thunderstorms, hazards include lightning, treefalls and brief squalls that can disrupt power and traffic. Secure loose objects on balconies and terraces. Keep devices charged during unstable weather. Today’s risk is isolated, so bursts may be hyperlocal and fast moving.
Kerala weather today: IMD yellow alert districts and peak hours
Districts on watch today span Pathanamthitta, Idukki, Ernakulam, Kozhikode, Wayanad and Kannur. Cross‑check district‑wise warnings because alerts are upgraded or withdrawn through the day. Monitor IMD nowcasts, which refresh every three hours, and track lightning on the Damini app. Watch Kochi radar loops for approaching cells before the peak commute window.
Kerala weather today: coastal and high‑wave caution
Beachgoers and fishers should note a high‑wave advisory until 11:30 pm today. INCOIS flags 0.7–1.1 metre waves along stretches of Thiruvananthapuram, Kollam, Kozhikode and Kannur coasts. Avoid rock fishing, sea bathing and beach parking during peaks. Moor boats securely and keep away from surf‑exposed jetties. Sea attack is possible at vulnerable stretches during the peak window.
Kerala weather today: commute and safety checklist
Plan city commutes around possible waterlogging near drains, underpasses and low‑lying junctions. If skies darken, reduce speed and avoid flooded lanes. Park clear of trees and hoardings. Unplug non‑essentials during nearby lightning. Schools and offices should keep staggered dispersal or remote options ready if nowcasts intensify. Avoid basement parking during cloudbursts.
Keep tracking IMD district warnings and station nowcasts through the evening, as alerts can shift quickly. Use the Met Centre Thiruvananthapuram site, KSDMA updates and Damini notifications for timely cues. Together, they reflect Kerala’s fast‑changing convective weather today, and guide safer travel windows.
