The maritime ports of Chattogram, Cox's Bazar, Mongla and Payra were advised to hoist distant warning signal number 2 today, instead of cautionary signal number 1, as the depression over the southeast Bay and adjoining Andaman Sea intensified into cyclonic storm "Yaas".
In a special weather bulletin, the Met Office said at 6am today that it was about 775 km south-southwest of Chattogram port, 605 km south-southwest of Cox's Bazar, 650 km south of Mongla port and 605 km south of Payra port.
It is likely to intensify further and move in a north-northwesterly direction.
The maximum sustained wind speed within 54 km of the deep depression centre is about 62 KPH, rising to 88 KPH in gusts or squalls, the bulletin said.
The sea will remain very rough near the depression centre.
All the fishing boats and trawlers over the north Bay and deep sea have been advised to remain close to the coast and proceed with caution. They were also advised not to venture into the deep sea.
