Chennai: Wet days are here again in Chennai. The city receivedmoderate rainfall on Friday. Officials said these are pre-northeast monsoon showers as the monsoon is likely to set in only from October 27-28. Depression in the sea is also expected which may grow into a cyclone and hit the state coast by month-end.

He said the northeast monsoon was on course and would set in from October 28. “The pre-monsoon showers were not wide spread. South Tamil Nadu received more rain on Friday compared to other parts of the state, where isolated rainfall was noticed. Similar showers have been forecast for the next 48 hours”.
