Northeast Monsoon to Bring Heavy Rainfall to Southern India

Overview of the Northeast Monsoon

The India Meteorological Department (IMD) has indicated that the Northeast Monsoon is anticipated to begin over southern peninsular India approximately on October 15-16, 2024. This seasonal transition is expected to produce significant rainfall, especially affecting states like Tamil Nadu, Kerala, and South Interior Karnataka. The initial phase of the Northeast Monsoon is a pivotal meteorological occurrence for these areas, frequently resulting in substantial agricultural advantages and difficulties.

Forecasted Precipitation and Impacted Areas

In a press release today, the IMD emphasized that a low-pressure system over the southeast Bay of Bengal is influencing the prediction of isolated very heavy to extremely heavy rainfall in these areas from October 14 to 17. Coastal Andhra Pradesh and Rayalaseema are anticipated to receive significant rains from October 14 to 16. The IMD forecasts isolated instances of exceptionally heavy rainfall in Tamil Nadu, Puducherry, and Karaikal on October 15-16, while South Interior Karnataka is expected to see severe rainfall on October 17. This may result in localized floods, waterlogging in low-lying regions, and transportation interruptions, especially in urban areas.

Contemporary Meteorological Trends

Recent meteorological data reveal significant to excessive precipitation in isolated areas of Tamil Nadu, Puducherry, Karaikal, and Vidarbha. Additional regions, such as Gujarat, Rayalaseema, and certain areas of Madhya Pradesh, have also experienced substantial rainfall. The IMD has advised inhabitants in these regions to stay alert, as the intense rainfall may result in unfavorable conditions, such as diminished visibility and traffic disturbances.

Recession of the Southwest Monsoon

The IMD has confirmed the withdrawal of the Southwest Monsoon from the remaining regions of Assam, Meghalaya, and the majority of the northeastern states as it continues to recede from various parts of the country. The present withdrawal line now reaches across designated coordinates, indicating a distinct change to the Northeast Monsoon. This transition is vital for the agricultural industry, since the Northeast Monsoon generally delivers critical precipitation for the rabi crop season.

Conclusion and Recommendations

Residents in the impacted regions are urged to remain vigilant and ready for the forthcoming substantial rainfall, particularly on October 15-16. The IMD will persist in monitoring the situation and furnish updates as required. The public is urged to consult the IMD's official announcements for comprehensive predictions and warnings, and to remain informed about regional meteorological conditions.
