The maritime ports of Chittagong, Cox’s Bazar, Mongla and Payra were advised to hoist local cautionary signal No 3 on Tuesday evening instead of distant warning signal No 2 as the depression over the Southeast Bay and adjoining the Andaman Sea intensified into cyclonic storm Yaas.
The severe cyclone storm over the northwest bay and adjoining area moved north-westwards further and now lies over the same area, reports UNB.
In a special weather bulletin, the Met Office said at 3pm Tuesday, it was centred about 520 km Southwest of Chittagong port, 520 km Southwest of Cox's Bazar port, 425 km South-southwest of Mongla port, and 420 km South-southwest of Payra port.

They will remain open to collect and exchange cyclone related information across the country, including the coastal areas, according to a press release issued on Tuesday.
