Light to Moderate Rain Forecast in Calcutta During Durga Puja
The weather office says Calcutta may get some rain during Durga Puja.
The rain is expected to be light or moderate, not very heavy.
The forecast includes possible showers from October 15 to 17, with light rain in some places on October 18 and 19.
Dry weather is expected later.
A weather system is forming over the sea and is expected to move toward the southern part of India.
It may change the winds and bring moisture to the region.
The monsoon is also expected to leave South Bengal by early next week.
Last year, very heavy rain caused serious disruption in the city, but officials say heavy showers are unlikely this time.
The Met office expects generally cloudy skies and light to moderate rain or thundershowers in Calcutta from October 15 to 17.
Light rain may affect some areas on October 18 and 19, while dry weather is expected afterward.
A Met official said heavy showers are unlikely, and rain influenced by the Bay system could begin on October 14.
A developing weather system is expected to move from the Gulf of Thailand toward the Andaman Sea, then strengthen toward the Tamil Nadu-Andhra Pradesh coast.
The monsoon is expected to withdraw from South Bengal by early next week; officials said the Bay system may alter winds and bring moisture.
