At least 29 tropical cyclones have affected Myanmar, a country adjacent to the Bay of Bengal in mainland Southeast Asia. Myanmar has witnessed some of the deadliest storms in the Bay of Bengal, including Cyclone Nargis in May 2008, which struck the low-lying Irrawaddy Delta near Yangon. Its winds and storm surge killed an estimated 140,000 people and left nearly $10 billion in damage. The country's worst natural disaster in the 20th century was a cyclone in 1968, which killed more than 1,000 people when it hit Rakhine State in northwestern Myanmar. One of the most powerful storms to ever hit the country was Cyclone Mocha, which it moved ashore northwestern Myanmar in May 2023, killing at least 413 people.
