More Rain Expected Across Tamil Nadu on October 15
Rainfall activity is expected to continue on Thursday, October 15, with a wider area of Tamil Nadu likely to experience unsettled weather.
The RMC has forecast heavy rain, thunderstorms, lightning and gusty winds reaching 40–50 kmph at isolated places in the Ghat areas of Tenkasi and Tirunelveli, as well as Kanniyakumari, Madurai, Dindigul, Tiruppur, Coimbatore, the Nilgiris, Erode, Salem, Namakkal, Karur, Tiruchirappalli, Perambalur, Ariyalur, Pudukkottai and Nagapattinam.

What Is Causing the Rainfall?
According to the weather department, the current rainfall activity is associated with an upper-air cyclonic circulation over the southwest Bay of Bengal, off southern Sri Lanka, and an easterly trough extending towards the central Bay of Bengal.
These weather systems are contributing to cloud formation and rainfall across parts of Tamil Nadu, with further showers expected over the coming days. <Cite refs={[“turn280615search1″,”turn280615search4”]}/>
