Chennai residents woke up to a rainy Diwali day on Monday with several areas, including Mylapore, Thiruvallikeni, Thiruvanmiyur, Kottivakam, Palavakkam, Tambaram, and Chromepet, witnessing heavy showers. While moderate to heavy rains are expected on Monday, conditions are likely to worsen over the next few days, according to weather experts.

A yellow alert warning for extremely heavy rain has been issued for the capital  Chennai on October 21, 22, and 23, and an orange alert warning for extremely heavy rain on October 23. The sky will be partly cloudy in Chennai and its suburbs on Monday and Tuesday.

The Indian Meteorological Department’s warning that heavy rains could drench the capital city has prompted the government to step up measures. Tamil Nadu Chief Minister M.K. Stalin stated that authorities have been taking precautionary measures for the past three months. “We are ready to face any amount of rain in Chennai,” he told reporters.

Not just Chennai, the Meteorological Department has issued an important announcement for 18 districts in Tamil Nadu as the North West monsoon intensifies.  

The northeast monsoon has begun in Tamil Nadu and will intensify further in the coming days. There is also an atmospheric circulation  prevailing over the South Andaman and the adjoining southeast Bay of Bengal. Due to this, a low-pressure area is likely to form over the southeast Bay of Bengal by October 21. It is likely to move west-northwestwards and strengthen into a depression in the next 24 hours. The public has also been advised to be safe as there will be strong winds and thunder, and lightning in some places.
