Cyclone Hudhud is pounding the eastern Indian coast, causing extensive damage and prompting the evacuation of some 350,000 people.
At least three people have been killed in Andhra Pradesh and three in Orissa.
The cyclone, classed "very severe", brought winds of 205km/h (127mph), as it passed over the coast near the city of Visakhapatnam.
The winds and heavy rains have brought down trees and power lines, and damaged crops and buildings in both states.
It is feared a storm surge of up to two metres could inundate low-lying areas and hundreds of relief centres have been opened in the two states. Disaster relief teams have also been sent.
