Kerala is currently experiencing heavy monsoon rains, prompting the India Meteorological Department (IMD) to issue an orange alert for seven districts. The affected districts are Pathanamthitta, Kottayam, Ernakulam, Idukki, Thrissur, Malappuram, and Wayanad. An orange alert signifies the possibility of very heavy rainfall, ranging from 12 cm to 20 cm within a 24-hour period. The IMD has also issued a yellow alert for the remaining districts, indicating the possibility of heavy rainfall between 7 cm and 12 cm.
The heavy rains have led to rising water levels in several rivers, including the Manimala, Pamba, Muvattupuzha, Bharathapuzha, Meenachil, Achankovil, Periyar, Chalakudy, and Kabani. Authorities have urged residents in low-lying and coastal areas to remain vigilant. The water level in the Mullaperiyar dam has reached 135.75 feet, and Tamil Nadu has indicated that it may open the dam's shutters if the water level crosses the 136-feet mark. As a precautionary measure, authorities are relocating 3,220 people from vulnerable areas.
In anticipation of potential flooding and landslides, the IMD advises preparedness for possible transportation disruptions and power outages. Squally weather with wind speeds of 40-50 kmph, gusting to 60 kmph, is expected along the Kerala coast. A high wave alert has also been issued for the coast from Kunjathur in Kasaragod to New Mahe in Kannur, with waves expected to reach 3.1 to 3.4 meters. Fishermen and coastal residents are strongly advised to stay away from the sea.
Several dams in the state have opened their shutters to manage the rising water levels. The Banasura Sagar dam in Wayanad opened one shutter, releasing water into the Panamaram river. The Peechi dam in Thrissur will open four shutters, which may raise water levels in the Manali and Karuvannur rivers. Shutters of the Palakkad's Malampuzha dam have also been raised. Additionally, eleven shutters of the Bhoothathankettu barrage, six of the Malankara dam, and the gates of the Kakkayam dam have been opened.
The heavy rains have already caused significant disruption across the state. Kochi city has experienced widespread waterlogging, and the KSRTC bus stand in Ernakulam was flooded. The Periyar and Muvattupuzha rivers have breached their banks, flooding homes in the vicinity. An unusual rise in the water level of the Manimala river has prompted an orange alert. Educational institutions in Kottayam that are serving as relief camps and schools under the Thrissur District Education Office will remain closed.
The current weather conditions are attributed to a low-pressure area that has formed over Saurashtra-Kutch and the adjoining northeast Arabian Sea. A cyclonic circulation has also formed over southwest Bangladesh and Gangetic West Bengal. While a temporary relief from the rains is expected on June 28, the IMD forecasts a return of intense rainfall on June 29 and 30.
