The India Meteorological Department (IMD) has issued a heavy rain alert for parts of South India while several northern states, including Delhi, Uttar Pradesh, Bihar, and Rajasthan, are set to experience an intense cold wave. According to the latest bulletin, the weather system forming over the Bay of Bengal has strengthened into a depression, resulting in widespread rainfall across Tamil Nadu and Kerala on Tuesday, December 3.

Alongside heavy rainfall predictions in the southern coastal regions, IMD has also warned of fog and cold wave conditions spreading across North, East, and Central India over the next few days. Travelers and residents have been advised to take precautions due to both weather hazards and visibility issues.

Heavy Rain Likely in Tamil Nadu and Kerala

The IMD has forecast heavy to very heavy rainfall in parts of north coastal Tamil Nadu on December 3. The depression over southwest Bay of Bengal is likely to bring strong moisture winds towards the coastline, increasing the risk of localized flooding and waterlogging in low-lying areas.

• Heavy rainfall expected at isolated locations in Tamil Nadu

• Light to moderate rain likely across most parts of Kerala

• Thunderstorms and strong winds possible in coastal belts

Officials have urged fishermen to avoid venturing into rough sea conditions.
