Scattered rainfall is likely across Tamil Nadu from January 7, prolonging the Northeast monsoon. Some southern districts may receive heavy rainfall for two days.
The Regional Meteorological Centre (RMC) has forecast rain over coastal areas starting Wednesday, which will then spread to other regions on Thursday. While light to moderate rain is likely to last in a few places till January 11, southern and delta districts are expected to receive heavy rainfall on January 9 and 10.
Six districts, including Ramanathapuram and Mayiladuthurai, may experience heavy rain on Friday, and districts such as Cuddalore, Thanjavur, and Villupuram may record intense rainfall on Saturday.
The monsoon has spilled over into January this year, too, like many other years previously. B. Amudha, Head (Additional in-charge), RMC, said that a low-pressure area has formed over the southeast Bay of Bengal and adjoining east Equatorial Indian Ocean on Monday evening under the influence of the upper air cyclonic circulation. The weather system is likely to become more marked by Tuesday evening and influence rainfall activity over the State, particularly coastal and southern districts.
“We will monitor rainfall activity over the region before deciding on the withdrawal of the monsoon. Sustained dry weather conditions for a few consecutive days are among the key criteria for declaring the withdrawal,” she said.
