At least two persons were electrocuted to death and around 80 houses partly damaged after a storm, which West Bengal Chief Minister Mamata Banerjee described as a "tornado", hit Hooghly and North 24 Parganas districts on Tuesday.

The natural event struck hours before Cyclone Yaas makes landfall near Dhamra Port in Odisha's Bhadrak district early on Wednesday, in the wake of which the Bengal government has evacuated over nine lakh people to safe shelters.
