The India Meteorological Department (IMD) has issued yellow and orange alerts across various southern states as persistent heavy rains continue to batter the region. The warnings come amid forecasts of isolated heavy to very heavy rainfall, thunderstorms, and squally winds impacting parts of Kerala, Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, and neighboring regions through mid-September 2025. Authorities and residents are advised to exercise caution and stay updated as the weather system brings fluctuating intensity and localized hazards.
Key Highlights: Southern States Under Alert
Kerala, Telangana, and Andhra Pradesh remain under continuous alert for heavy rainfall accompanied by strong winds and thunderstorms until September 12-14, with some districts experiencing isolated very heavy downpours.
Tamil Nadu is largely under a yellow alert, signaling the likelihood of heavy rain and gusty winds, while specific coastal regions may face comparatively lighter rainfall.
Karnataka’s districts including Bengaluru, Mysore, and others are exposed to yellow alert status for heavy showers, with forecasted surface winds reaching 40-50 kmph.
Telangana’s northern districts such as Adilabad, Nizamabad, and Kamareddy face the more severe orange alert, forewarning of very heavy rain, intense thunderstorms, and lightning.
Meteorological Causes and Weather System Dynamics
The IMD reports an evolving low-pressure area over the northwest Bay of Bengal, expected to intensify into a depression, fueling moisture influx over peninsular India.
Upper air cyclonic circulation over the northeast Bay of Bengal and adjoining Myanmar coast further contributes to the wet weather pattern.
Enhanced wind flow and humid conditions lead to the formation of cumulonimbus clouds delivering heavy precipitation and localized gusty winds.
Such dynamic weather systems are typical of the retreating monsoon phase, often causing concentrated bursts of heavy rainfall.
Regional Impact and Preparedness
Heavy rainfall exacerbates risks of flooding in low-lying urban zones, waterlogging on highways, and disruption in transit schedules.
The orange alert areas should prepare for possible flash floods, strong wind gusts, and vulnerability to tree falls or minor structural damages.
Agricultural activities in affected states may face short-term challenges due to waterlogging and strong winds, urging farmers to take precautionary measures.
Coastal fishing communities receive advisories against venturing into the sea during intense weather spells.
Precautions and Public Advisory
Residents in affected zones are advised to avoid non-essential travel, keep emergency kits ready, and monitor official updates continuously.
Authorities emphasize maintaining cleanliness of drainage systems to mitigate flood risks.
Power suppliers notify preparedness for swift restoration in case of outages, and disaster response teams remain on alert for immediate interventions.
Schools and offices are encouraged to implement flexible hours or closures depending on local conditions.
Outlook for the Coming Week
The northern and northeastern sectors of India show signs of fluctuating rainfall, with localized heavy showers continuing through mid-September.
Peninsular states will gradually see the intensity of rains decrease after September 14, though isolated showers and thunderstorms may persist.
Seasonal transition towards drier winds is expected in the weeks ahead but climate experts caution vigilance due to unpredictable weather anomalies.
Conclusion
The IMD’s yellow and orange alerts signal a critical phase of heavy rainfall impacting southern India, with concentrated risks in Telangana and adjoining coastal areas. These weather developments underscore the need for heightened readiness from residents and authorities alike to ensure safety and minimize disruptions. As the monsoon wanes and the region braces for continued showers, timely information and proactive measures remain invaluable to navigate the challenges posed by the evolving atmospheric conditions.
