Chennai, Feb 21 || A fresh low-pressure area is likely to form over the southeast Bay of Bengal on Saturday, the Meteorological Department said, even as parts of south Tamil Nadu brace for heavy rainfall under the influence of prevailing atmospheric conditions.
According to officials, an atmospheric circulation persisting over south Tamil Nadu and adjoining south Kerala is expected to trigger widespread showers accompanied by thunderstorms in several districts.
Heavy rain is forecast for Kanyakumari, Tirunelveli, Thoothukudi, Tenkasi, Virudhunagar and Theni districts.
The weather office has cautioned that thunderstorms with lightning and intense spells of rain may occur in isolated pockets across these districts.
Residents in low-lying and vulnerable areas have been advised to remain alert, particularly in regions prone to waterlogging and localized flooding.
