Chennai rains had remained light in nature since the beginning of the month of October itself. Before that, rainfall activity had remained on the backseat with the city witnessing dry weather conditions for about ten days or so.
These rainfall activities have been attributed to the presence of a Cyclonic Circulation over Southwest Bay of Bengal and adjoining Sri Lanka and Tamil Nadu Coast.
Now, also, rainfall activity is expected to continue over the city of Chennai and adjoining cities in the next 24 hours and rains will remain moderate to heavy in nature. Meanwhile, rainfall may reduce after 24 hours, but on and off showers will continue over the city of Chennai.
