KOLKATA: The city remained cloudy with intermittent drizzles even as monsoon is “set to advance into West Bengal over the next 48 hours”.
Kolkata and some of its adjoining districts may receive heavy rain on Friday as a cyclonic circulation over northwest Bay of Bengal is likely to trigger a low-pressure area.
It is likely to get more marked during the subsequent 24 hours and move towards Odisha.
“Till the system remains a low pressure over northwest Bay of Bengal on Friday, it will be nearer to Kolkata.
So, the city is likely to receive heavy showers.
Once it turns into a depression and moves towards Odisha, the impact on Kolkata will lessen.
We expect 70mm-110mm in the city over the next four days,” said Regional Meteorological Centre (RMC) director GK Das.
He added that if the city receives enough rain and the other conditions are met, monsoon may arrive in Bengal on Friday.
“If not, then we expect the currents to cover the entire state by Saturday,” added Das.
Along with Kolkata, heavy rain has been predicted in Howrah, North and South 24 Parganas, East and West Midnapore on Friday.
“Kolkata will receive heavier showers on Friday, after which the rain could be light to moderate.
But since monsoon will set in and the rain will continue, the temperature will remain low,” added Das.
He added that early monsoon rain in Kolkata is referred to as ‘summer monsoon’ since precipitation is inconsistent and often scanty during the early part of the season in Kolkata.
