Kolkata: Monsoon is set to hit north Bengal within the next 72 hours, Kolkata could receive a moderate thunderstorm on Monday. There is still no indication about the possible date of monsoon’s arrival in south Bengal and Kolkata.
The Met office said that this may not be the last thunderstorm before the monsoon arrives. If conditions turn favourable before the arrival of rains, there could be more.Last year, monsoon struck Kolkata on June 12.
A circulation over Bangladesh could trigger the storm, but the chances of a squall were ruled out. A low-pressure or a cyclonic circulation over Bay of Bengal usually precedes the monsoon in south Bengal. Loud clouds will trigger mild thunderstorms rather than squalls.
Monsoon currents have reached Tripura and parts of central Assam. The currents have reached Agartala and are set to advance towards north Bengal.
According to the Regional Meteorological Centre (RMC), Monsoon hit Kerala on last week and could reach Kolkata and south Bengal by June 10, which is monsoon’s normal date of arrival in Bengal.
Though there are no reasons to slow down the monsoon currents, weathermen are keeping their fingers crossed till the rains hit the Northeast and north Bengal over the next three days. Kolkata, however, could receive a thundershower on Thursday.
The mercury levels fell several notches on Friday after heavy rains struck night. The maximum temperature fell below 30 degrees Celsius for the first time in the last two weeks after it was recorded at 35 degrees Celsius. At least eight people were killed and several others injured in separate incidents of lightning strike and a wall collapse on Friday.
The regional meteorological department has predicted similar weather to continue on Monday as well. On Friday heavy rainfall lashed different parts of the South Bengal districts. In Kolkata and its adjoining areas, there was heavily rainfall from around 10 am in morning.
