KOLKATA: The city woke up to an unseasonal thunderstorm and an incessant drizzle, which occasionally got heavier and drenched the city for more than two hours on Friday morning. The gust of wind played havoc with flights at the city airport, leading to delays and diversions.
It was triggered by two low-pressure troughs — one across Haryana and Bihar and another that stretched between Bihar and Telngana. The showers returned in evening with the city receiving 27.4 mm rain during the day.
