Tamil Nadu, Andhra Pradesh: The India Meteorological Department (IMD) has issued heavy rainfall warnings for Tamil Nadu and Andhra Pradesh due to a “well-marked low-pressure area” over the southwest and adjoining southeast Bay of Bengal. The weather system is expected to bring significant rainfall to several regions of southern India on Wednesday, December 11, and Thursday, December 12.

The weather department has forecast light to moderate rainfall over many areas of Tamil Nadu, Puducherry, and Karaikal, with thunderstorms and lightning in a few locations. Heavy to very heavy rainfall is likely in isolated areas of districts like Cuddalore, Mayiladuthurai, Nagapattinam, Thanjavur, Tiruvarur, and Pudukkottai on December 11. Other regions such as Sivaganga, Ramanathapuram, Tiruchirappalli, Perambalur, Ariyalur, and Kallakurichi are also expected to receive heavy rain.

Andhra Pradesh & Rayalaseema:
Coastal Andhra Pradesh and Rayalaseema are likely to experience heavy rainfall at isolated places on both December 11 and 12. The IMD has urged caution, particularly in regions near the coast, as the low-pressure system continues to move toward the Tamil Nadu-Sri Lanka coast.
