Tun Lwin (, also Htun Lwin; 17 January 1948 – 4 November 2019) was a Burmese meteorologist who warned of the approach of the deadly Cyclone Nargis in 2008, but was largely ignored by local people and authorities in the Irrawaddy Delta. He served as Director-General of Department of Meteorology and Hydrology. Tun was a familiar sight on television screens long before he became Myanmar's favorite and most followed weatherman. His nightly appearances as a weather forecasting official from the government's Meteorology and Hydrology Department usually right before the evening movie was due to start—used to annoy many viewers across Myanmar. Early life and education Tun Lwin was born on 17 January 1948 in Kula Village, Ngazun, British Burma, to parents Theing Maung and Aye Gyi. He is the eldest of two siblings, having a younger brother. He grew up in Mandalay and attended Lafom Memorial High School in Mandalay. He received a master's degree in meteorology from Florida State University in the US, and a PhD from Yangon University in July 2018. Career Tun has worked in Burma's Department of Meteorology and Hydrology since 1965 when he was 17 years old in 1965. He then served as Deputy-Director in the Ministry of Meteorology and Hydrology until 2003 when he was promoted to Director General of Department of Meteorology and Hydrology. One of the most notable occurrences during his appointment was Cyclone Nargis, the worst natural disaster to hit Myanmar in recorded history. Despite the high number of casualties and devastation, he was commended after initial criticism for his prediction and speedy warning of the Cyclone especially considering the limited resources and political bureaucracy of Burma at the time. After 44 years in total at the DMH, he retired in 2009. After his retirement, he actively engaged in raising awareness about the need to adequately prepare for natural disasters. He was a well-known, active "netizen" in Myanmar who operated a free, non-profit service as Myanmar Climate Change Watch (MCCW). In addition to giving talks and appearing on various media such as newspapers, journals, magazines, television and radio channels to educate the public on weather and climate, he also provided free weather updates through Facebook where he also sometimes posted updates and anecdotes about his own personal life and opinions. He has written numerous successful books on weather in Myanmar, worked with local radio stations on weather-related segments and regularly wrote
