The Regional Meteorological Centre in Chennai has predicted heavy rainfall in six districts of Tamil Nadu on January 9 and 10. This weather phenomenon is attributed to prevailing atmospheric circulations over the Arabian Sea and nearby regions. A low-level cyclonic circulation is currently present over the south Kerala coast and the southeast Arabian Sea, while an upper-level cyclonic circulation has formed over the southeast Arabian Sea, the adjoining southwest Arabian Sea, and equatorial regions. These systems are expected to impact rainfall activity across parts of Tamil Nadu in the coming days.
Coastal districts of Tamil Nadu may experience light to moderate rainfall on Monday and Tuesday, while interior districts are likely to have dry weather. Additionally, there may be light mist or shallow fog in some areas during the early morning hours, affecting visibility. The intensity of rainfall is anticipated to rise from January 9, with heavy rain expected in isolated places in districts like Mayiladuthurai, Tiruvarur, Nagapattinam, Thanjavur, Pudukkottai, and Ramanathapuram.
On January 10, heavy rainfall is projected to shift slightly northwards to districts including Villupuram, Cuddalore, Mayiladuthurai, Tiruvarur, Nagapattinam, and Thanjavur. Fishermen and coastal workers are advised to stay updated on official weather bulletins due to potential changes in wind patterns and sea conditions accompanying the rainfall. Authorities have urged vigilance from district administrations to monitor vulnerable areas and ensure drainage systems are prepared. The Meteorological Office will continue monitoring the evolving weather systems and issue necessary updates. Residents are advised to follow official advisories and avoid unnecessary travel during periods of intense rainfall, especially in districts under heavy rain warnings.
