Tropical Cyclone Vayu is expected to bring heavy flooding rain, strong wind, and storm surge to parts of India later this week.
Authorities have evacuated almost quarter-million people in preparation of the storm.
Tropical Cyclone Vayu is less south-southeast of Karachi, Pakistan, and is moving northwestward.
Early on June 10, a depression formed in the Arabian Sea, just northwest of the Maldives.
As the system moved northward, it gradually strengthened, becoming a deep depression, before intensifying further into Cyclonic Storm Vayu later that day.
After being upgraded to a severe cyclonic storm on June 11, and concurrently to Category 1 on the Saffir–Simpson hurricane wind scale, the system began a period of rapid intensification.
Vayu strengthened into a very severe cyclonic storm soon afterwards, and reached Category 2-equivalent tropical cyclone status by June 12.
