As tropical storm one made landfall in Bangladesh, it brought winds of 70 mph and a storm surge up to 3 meters high and heavy torrential rains and flooding, killing around 11,069 people. Every single person on the island of Urir Char, approximately 500 at the time, is thought to have been swept into the Bay of Bengal. A pilot who flew over the island said it was swept by waves, like it was inside the fireball on an atomic bomb. A total of 1.3 million people were affected. Approximately 137,000 homes were damaged, 102,000 of them were destroyed, 133,00 acres of crops damaged, and 120,000 cattle were killed.
