Media on Cyclone 'SITRANG' (Indian Express, 25Oct2022):

 Power and telephone links have been largely cut and coastal areas plunged into darkness, officials said.

A tropical storm that lashed Bangladesh left at least 35 people dead and about 8 million without power across the delta nation, officials and news reports said on Tuesday.

The government said about 10,000 homes were damaged and more than 6,000 hectares (15,000 acres) of crops were destroyed. Thousands of fishing projects were also washed away.

 The United News of Bangladesh news agency said about 20,000 people were marooned because of flooding triggered by tidal surges in the southern coastal district of Bhola.

Tropical Storm Sitrang brewed in the Bay of Bengal before turning north toward Bangladesh’s vast coast, prompting authorities to evacuate hundreds of thousands of people to cyclone shelters Monday. Heavy rains battered the country throughout the day, flooding many areas in the coastal regions across southern and southwestern Bangladesh.
