Chennai is set to experience a week-long spell of rain as the Northeast Monsoon is expected to arrive around October 15.

After a largely dry start to October, rainfall activity is likely to increase across Chennai and coastal Tamil Nadu.

A cyclonic circulation over the Southwest Bay of Bengal and Gulf of Mannar is expected to bring widespread showers, with rainfall becoming more frequent and intense over the next 48 hours.

Between October 15 and 21, Chennai and surrounding areas may experience moderate to heavy showers, particularly during the night and early morning hours.

Thunderstorms, lightning and gusty winds are also possible across Tamil Nadu. Residents are advised to stay cautious and check the Rain Radar for updates.
