Bengaluru, October 22, 2025 — The Indian Meteorological Department (IMD) has issued a heavy rainfall warning for multiple districts in southern Karnataka, including Bengaluru, Mysuru, and coastal regions, prompting concerns about potential school closures and disruptions on October 23, 2025. The forecast, driven by a cyclonic circulation over the Bay of Bengal, predicts intense rainfall across the state, with coastal districts like Dakshina Kannada and Udupi on high alert for worsening conditions. Authorities are closely monitoring the situation, and school holidays may be declared if the weather deteriorates further, following similar measures in neighbouring states like Kerala and Odisha.
According to the IMD, a low-pressure system in the Bay of Bengal is expected to intensify, bringing heavy to very heavy rainfall to southern Karnataka from October 22 through October 24. Bengaluru, known for its susceptibility to urban flooding, is likely to experience significant downpours, with rainfall accumulation expected to range between 60-100 mm in some areas. Coastal districts, including Dakshina Kannada, Udupi, and Uttara Kannada, are under an orange alert, signaling a high likelihood of severe weather, including thunderstorms and localized flooding.
Mysuru, Chamarajanagar, and Kodagu are also expected to face heavy rainfall, raising concerns about landslides in hilly areas and waterlogging in urban centers. The IMD has warned of potential disruptions to transportation, power supply, and daily activities, urging residents to stay updated on weather advisories and avoid non-essential travel.
In response to the IMD’s warning, district administrations across southern Karnataka are preparing for potential school closures on October 23. In Bengaluru, the Deputy Commissioner has indicated that a decision on declaring a holiday for schools and colleges will be made by the evening of October 22, based on real-time weather updates. “The safety of students and staff is our top priority. We are in constant coordination with the IMD and will announce closures if conditions pose a risk,” said a senior official from the Bengaluru Urban District Administration.
Coastal districts like Dakshina Kannada and Udupi, which frequently experience heavy monsoon impacts, are on high alert. Local authorities have stated that schools may remain closed on October 23 and possibly October 24 if rainfall exceeds safe thresholds. “We are monitoring water levels in rivers and low-lying areas. A holiday will be declared if commuting becomes hazardous,” said the Deputy Commissioner of Dakshina Kannada.
This approach mirrors recent actions in Kerala, where schools in several districts, including Thiruvananthapuram and Ernakulam, were closed earlier this week due to torrential rains. Similarly, Odisha declared holidays in coastal districts like Puri and Cuttack after heavy rainfall caused widespread waterlogging and traffic disruptions.
The heavy rainfall warning has prompted authorities to implement several precautionary measures. In Bengaluru, the Bruhat Bengaluru Mahanagara Palike (BBMP) has deployed teams to clear stormwater drains and monitor flood-prone areas such as Koramangala, Hebbal, and Bellandur. Residents have been advised to avoid underpasses and low-lying areas during heavy rain. The Karnataka State Disaster Management Authority has also activated helplines and emergency response teams to assist with potential evacuations in vulnerable regions.
In coastal Karnataka, fishermen have been advised to refrain from venturing into the sea until October 25 due to rough weather conditions. Schools and colleges in Mangaluru and Udupi have been directed to prepare for online classes in case physical attendance is halted. Meanwhile, in Mysuru, authorities are focusing on preventing disruptions during the ongoing Dasara festivities, with contingency plans in place to ensure tourist safety.
The situation in Karnataka follows a pattern of weather-related disruptions in Kerala and Odisha, where heavy rainfall led to school closures and restrictions on public movement. In Kerala, the state government issued red alerts for northern districts, with schools and colleges shifting to online modes to ensure continuity of education. Odisha, meanwhile, faced challenges with flooded roads and power outages, prompting swift action from local administrations to restore normalcy.
Karnataka’s authorities are drawing on these experiences to streamline their response. “We are in touch with our counterparts in Kerala and Odisha to understand their strategies. Our focus is on minimizing disruptions while ensuring public safety,” said a spokesperson from the Karnataka State Education Department.
The IMD and local authorities have urged residents to take precautions during the heavy rainfall period:
For Bengaluru residents, the BBMP has provided a helpline number (1533) for reporting waterlogging or other rain-related issues. Coastal district administrations have also set up control rooms to address emergencies.
As southern Karnataka braces for heavy rainfall, the state is taking proactive steps to mitigate risks and ensure public safety. While the possibility of school closures looms, authorities are working to balance education continuity with the need to protect students and staff. Residents are encouraged to stay vigilant and follow official advisories as the weather system evolves.
