West Bengal may be clouded by low pressure on Bay of Bengal

KOLKATA: A low-pressure, set to form over north Bay of Bengal could trigger heavy showers in Kolkata and south Bengal this weekend. Weathermen expect the system to form in the course of the week and lead to heavy showers. Moderate rain is predicted in Kolkata and the rest of south Bengal through the week.
“Monsoon clouds have moved into the region last Thursday. Ever since the currents are in full flow and have been triggering rain regularly. The showers have so far been moderate in south Bengal. But they will get heavy in north Bengal this week,” said RMC Centre director GK Das.

Monsoon arrived in Kolkata and major parts of south and north Bengal on Friday and repeated drizzles drenched the city. Clouds had started moving into the region on Thursday riding on a low-pressure over Bay of Bengal.
On Friday, the monsoon currents covered most parts of Gangetic Bengal, Sikkim and north Bengal. The currents covered the rest of the state on Saturday.
This year, monsoon has arrived on schedule and with the currents moving steadily across the country, rain could be sufficient, felt experts.
“Monsoon is driven by low-pressures and depressions that trigger heavy showers and keep the rain count ticking,” said a meteorologist.
