Chennai Weather LATEST Update: IMD Warns of Lightning, Moderate Rain Across South Tamil Nadu Districts

Chennai Weather LATEST Update: The Regional Meteorological Centre has issued a short-term alert for parts of Tamil Nadu, warning of thunderstorms and rain over the next two hours due to prevailing atmospheric conditions in southern India

Thunderstorm Warning for Six Districts

The Regional Meteorological Centre has warned that thunderstorms accompanied by lightning may occur in parts of Tamil Nadu over the next two hours. The alert applies to Tirunelveli, Tenkasi, Kanniyakumari, Coimbatore, the hilly areas of Nilgiris, and Theni districts.

Rainfall is expected at isolated places until 7 pm today. Authorities have cautioned that low-lying areas may witness temporary waterlogging due to sudden spells of rain.

Atmospheric Circulation Behind the Rainfall

According to the weather department, the ongoing rainfall is being triggered by a lower-level atmospheric circulation prevailing over southern parts of India.

Southern districts have already been experiencing fairly widespread showers, and this fresh advisory has been issued as thunderstorms are likely to intensify in select pockets. Residents are advised to remain cautious during lightning activity.

Forecast for Coming Days

Earlier, the department had stated that South Tamil Nadu, districts along the Western Ghats, and adjoining regions could receive light to moderate rain at isolated places. Other parts of the state are expected to remain dry.
