IMD Predicts Onset of Southwest Monsoon Over Kerala Within Next 3 Days
The India Meteorological Department (IMD) announced the imminent onset of the Southwest Monsoon over Kerala, triggering disaster management preparations across the country. This development is significant as it marks the beginning of the monsoon season, which is crucial for India's agricultural sector and overall climate. The IMD has forecast heavy to very heavy rainfall over Kerala and Mahe between June 3 and June 7, with widespread rain expected across other parts of the country.
- •The Southwest Monsoon, a seasonal weather pattern that brings significant rainfall to India, is set to make its onset over Kerala within the next two to three days.
- •This marks the beginning of its advance across the country, with heavy to very heavy rainfall forecast over Kerala and Mahe between June 3 and June 7.
- •The India Meteorological Department (IMD) has predicted isolated heavy rainfall over parts of Northeast, including Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura during the week.

How the Monsoon Works
The timing and distribution of monsoon rainfall are influenced by climate systems such as El Nino, La Nina, and the Indian Ocean Dipole. Referring to Andhra Pradesh, 13 to 14 low-pressure systems form over the Bay of Bengal every year, most of them originating in the northern Bay. As these systems move along the monsoon trough, they bring heavy rainfall to north coastal Andhra Pradesh, Odisha, Chhattisgarh, Madhya Pradesh, and Gujarat. The Godavari and Krishna river basins are particularly vulnerable to hazards such as coastal inundation and flooding.

Significance and What Changes Now
The onset of the Southwest Monsoon is crucial for India's agricultural sector, as it accounts for a significant portion of the country's rainfall. The monsoon also has a significant impact on the country's economy, with a good monsoon season often leading to increased agricultural production and economic growth. However, the monsoon also poses significant challenges, including flooding, landslides, and waterborne diseases.
Did You Know? The Southwest Monsoon is responsible for approximately 70% of India's annual rainfall, making it a critical component of the country's climate system.
India's Position and Current Status
India is highly dependent on the Southwest Monsoon for its agricultural production, with the majority of the country's agricultural land being rain-fed. The monsoon season is also critical for replenishing the country's water resources, including reservoirs, lakes, and groundwater. The IMD has predicted a normal monsoon season for 2026, with rainfall expected to be around 90% of the long-term average.

Challenges on the Ground
Despite the importance of the Southwest Monsoon, the country faces significant challenges in managing the monsoon season. These challenges include flooding, landslides, and waterborne diseases, which can have a significant impact on human life and property. The country also faces challenges in managing its water resources, including reservoirs, lakes, and groundwater.
Way Forward
To address the challenges posed by the Southwest Monsoon, the government needs to take a proactive approach to disaster management and mitigation. This includes providing early warning systems, conducting evacuation drills, and providing support to affected communities. The government also needs to invest in infrastructure development, including the construction of dams, reservoirs, and canals, to manage the country's water resources effectively.
Concepts Mentioned
Sendai Framework for Disaster Risk Reduction
The Sendai Framework is a global plan for disaster risk reduction, aiming to reduce disaster losses. It is significant for promoting resilience and sustainability. Adopted in 2015, it has seven targets.
Disaster Management Act 2005
The Disaster Management Act 2005 is a law governing disaster management in India. It is significant for establishing a national framework for disaster response. The Act created the National Disaster Management Authority.
Indian Meteorological Department
The Indian Meteorological Department (IMD) is the national weather forecasting agency of India, responsible for monitoring and predicting weather conditions across the country. It plays a crucial role in disaster management, agriculture, and aviation by providing accurate weather forecasts and warnings. The IMD issues the India Meteorological Department's Cyclone Warning Centre, which issues cyclone warnings for the eastern coast of India.
National Institute of Disaster Management (NIDM)
The National Institute of Disaster Management is a premier institute for disaster management in India. It plays a crucial role in developing strategies for disaster mitigation. NIDM is headquartered in New Delhi.
National Disaster Management Authority
The National Disaster Management Authority is a government agency responsible for disaster management. It plays a crucial role in mitigating disasters. India's NDMA was established in 2005.
Indian Ocean Dipole (IOD)
The Indian Ocean Dipole is a climate phenomenon involving fluctuations in sea surface temperatures. It significantly impacts regional weather patterns. Australia's droughts are often linked to a negative IOD phase.
La Nina
La Nina is a complex weather phenomenon characterized by cooler ocean temperatures. It has significant implications for global climate patterns. La Nina events occur every 3-7 years.
El Nino
El Nino is a complex weather phenomenon characterized by warmer ocean temperatures. It significantly impacts global climate patterns, leading to droughts and floods. For example, it caused severe drought in Australia in 2010.
