Light rain is expected in Calcutta until Saturday, with dry weather likely from Sunday, a Met bulletin said on Wednesday.
This year, Sashthi is on Friday. Saturday and Sunday will be celebrated as Saptami, adding an extra day to the festivities.
The southwest monsoon retreated from Calcutta on Monday. By Thursday, it is expected to retreat from the rest of the country except the southern peninsula, where the northeast monsoon is likely to begin the same day, the Met office said.
A trough runs from a cyclonic circulation over Kanyakumari in Tamil Nadu to the northwest Bay of Bengal off Odisha coast, across the Gulf of Mannar, southwest Bay of Bengal and extends upto 1.5km above mean sea level, said the Met bulletin.
A cyclonic circulation that was over the north Andaman Sea on Monday was initially tipped to get stronger and move towards the Tamil Nadu-Andhra coast. But the system eventually merged with the trough, said a Met official.
