A well-defined low-pressure area weakened on Thursday as it moved inland toward the southern interior of Karnataka. It is expected to merge with the existing weather system over the Arabian Sea, which could bring heavy rainfall to the Western Ghats region and some northern Tamil Nadu districts, including Ranipet and
Vellore, on Friday.

Meanwhile, a new upper air cyclonic circulation is forming over the Bay of Bengal, which may lead to the development of another low-pressure area over the southeast and east-central Bay of Bengal on Friday. The Regional Meteorological Centre (RMC), Chennai, has predicted that this system will intensify by Saturday, resulting in widespread rainfall across parts of Tamil Nadu from Sunday onward.

On Thursday, most parts of Tamil Nadu received rainfall, with Arakonam in Ranipet district recording the highest rainfall of the day. Other areas such as Tiruchi, Thanjavur, Krishnagiri, and Kanniyakumari reported light to moderate rain until 6:30 p.m.
