Authorities have prepared more than 1,000 cycone shelters to evacuate people while all fishing boats and trawlers over North Bay and deep sea have been asked to remain anchored until further notice as Cyclone Sitrang is expected to cross southern Bangladeshi coast by early Tuesday.

The Bay of Bengal will remain very rough near the eye of the cyclone, the weather office said on Monday morning.

According to the latest bulletin of Bangladesh Meteorological Department, Sitrang may make landfall near Khepupara along Barishal-Chittagong coast, and because of the impact of the cyclone heavy rains would continue to lash the country.

Authorities in Chattogram and other hilly districts warned that landslides could destroy homes and kill people if incessant rains continue.

UNB correspondents from across southern coastal region reported heavy rains since morning.

In Barishal, local administration has prepared more than 1,000 cyclone shelters, said deputy commissioner Jasim Uddin.

In Khulna, authorities prepared 409 cyclone shelters that could accommodate more than 2.73 lakh people for any emergency, Md. Moniruzzaman Talukder, deputy commissioner in Khulna, told UNB.

He said steps have been taken to evacuate the people if the situation demands.

The Met office in Dhaka said the most vulnerable coastal districts--Satkhira, Khulna, Bagerhat, Jhalakathi, Pirojpur, Barguna, Patuakhali, Bhola, Barishal, Laxmipur, Chandpur, Noakhali, Feni and three others offshore islands could face the worst situation of flooding because of strom surge if the cyclone hit Bangladesh straight. The Met office said in its latest warning that these areas would come under danger signal 7. Strong wind could drive the storm surge the height of 5-8 feet above the normal astronomical tide in the region.

The maritime ports of Mongla and Payra have been advised to hoist danger signal No 7 while Chattogram and Cox's Bazar danger signal No 6 instead of local cautionary signal number 4.
