Also, the department has said, there lies a cyclonic circulation in the west central region, and adjoining south west Bay of Bengal in the lower tropospheric levels.
After some dry weather for the last few days, residents of the city can look forward to pleasant weather in the next 48 hours as there may be light or moderate showers in Chennai.
