The typhoon weakened Tuesday afternoon, with maximum sustained winds of 40 mph and wind gusts of up to 53 mph.
Weather in the capital Dhaka, which had recorded gusts of up to 55 mph on Monday night, said the danger had passed.
Raihan Mehbub, a government official in Cumilla district, said a couple and their four-year-old daughter died after a tree fell on their home on Monday night. They were sleeping and died on the spot.
At least thirteen other people were killed in separate incidents across the country, Dhaka-based Somoy TV reported. Most died after being hit by falling trees, others died from collapsed structures or drowning, local media reported.
Nasrul Hamid, deputy minister of electric power and mineral resources, said about 8 million users out of a total of 48 million were left without power after fallen trees broke distribution lines or power poles were knocked down, most commonly in rural areas.
He said nationwide power distribution would return to general until at least Wednesday.
