Thiruvananthapuram: The India Meteorological Department (IMD) has announced the withdrawal of the southwest monsoon from Kerala, marking the onset of northeast rainfall activity in the region. An orange alert has been issued for Malappuram and Kannur, predicting very heavy rainfall between 115.6 and 204.4 mm. Additionally, ten districts, including Pathanamthitta, Alappuzha, Kottayam, Ernakulam, Idukki, Thrissur, Palakkad, Kozhikode, Wayanad, and Kasaragod, are under a yellow alert, indicating heavy rainfall between 64.5 and 115.5 mm.
Moderate rain with thunderstorms is expected in isolated areas across all districts on Wednesday. The IMD forecasts rain with thundershowers at most locations in Kerala until October 21. A wind warning advises fishermen to refrain from venturing into the sea until October 19 due to squally weather conditions, with wind speeds ranging from 35 km/h to 45 km/h and gusts up to 55 km/h along the Kerala-Karnataka-Lakshadweep coast.
A swell surge warning is in effect for all coastal districts until 11 pm on October 16, with a red alert in Kollam and Thiruvananthapuram, where waves are expected to reach heights of 1.0 to 2.0 meters. A yellow alert is issued for other districts under similar wave conditions.
For Thursday, October 17, the alerts are as follows: Orange for Kozhikode and Kannur; Yellow for Thrissur, Palakkad, Malappuram, Wayanad, and Kasaragod.
Possible impacts from heavy rain include waterlogging on major roads, reduced visibility leading to traffic congestion, and risks of landslides, mud slips, and flash floods. Low-lying areas and riverbanks may experience flooding or waterlogging, while fallen trees could cause power outages or accidents. Partial damage to houses and shelters is anticipated, alongside potential harm to people and livestock.
The IMD advises efficient traffic management, discouraging unnecessary travel, and staying in safe areas. It is recommended to avoid vulnerable structures and postpone sowing seeds if already planted, to prevent water stagnation.
