KOLKATA: The low pressure over the sea turned into a depression on Sunday evening. However, the said that as long as the system didn’t shift over land, it would not officially declare the arrival of monsoon in the city. Pre-monsoon showers, however, continued keep the heat at in Kolkata on Sunday when most parts of the city witnessed sharp intermittent rain.
Up to 3.30pm, the KMC drainage pumping station had recorded 15.24mm rain in Behala, 11.18mm rain in , 12.95mm rain in Joka, 7.87mm on EM Bypass and 6.1mm in Chowbaga. Despite the disparity in its intensity, the rain was widespread. However, there was no major waterlogging as KMC drainage pumping stations managed to pump away the accumulated rainwater.
Work on the ground this year does not seem to have measured up with the requirements. Civic agencies should now focus on two important areas — road repairs and sewer work — to alleviate citizens’ pain.
The depression is likely to reach the Bangladesh coast by midnight on Sunday. “There is astrong possibility of this weather system moving over land by Monday. We can then ascertain other criteria before announcing the monsoon’s arrival,” said G K Das, director (weather) at Regional Meteorological Centre, Kolkata.
On Saturday, the low pressure had moved further over northeast Bay of Bengal. But though it was expected to cross over to the land by Sunday evening, it did not make much of a progress. Meteorologists cited several reasons, including the prevailing wind system, for the depression moving at a slow pace. Hills and mountains in its path was also a reason for its slow pace.
“The prevailing wind system is east-westerly, whereas it should be to be south-westerly, pushing the depression towards the land,” said Das.
The Met office had predicted monsoon would hit Kolkata between June 9 and 11. It is still hoping for the northern limit of the southwest monsoon to reach by Monday, triggering the first shower of the monsoon.
Monsoon had hit the Kerala coast on May 29. The scheduled date of its arrival in Kolkata was June 10. But according to the Met office, a margin of three days is normal in the meteorological dictionary. Last year, the southwest monsoon arrived in the city on June 12 while in 2016 and 2015, it arrived on June 17 and 20 respectively.
“Though the monsoon did not hit the city on June 10, we cannot say it has been delayed since an error margin of three days is considered normal,” said a source in the Met office.
