KOLKATA: Even as winter is set to bow out, the city is heading for yet another spell of cloud and drizzles triggered by a western disturbance (WD) — the fourth since December to have an impact on the region — on February 3 and 4.
It is the La Nina effect that has led to frequent WDs this season and led to the chain of events that eventually led to a dip in temperature repeatedly during the last two months, said weathermen. Kolkata received 13 mm rain in January, making it the second wettest beginning to the year since at least 2017.
