Original report, 18 August 2016:
Several countries in South East Asia have seen severe flooding over the last few days, including Thailand, Laos, Vietnam and Myanmar. There could be more severe weather to come as Tropical Storm Dianmu is predicted to head from China towards northern Laos and Vietnam.
In Thailand, flooding was reported in 4 states in the north since 12 August. The Department of Disaster Prevention and Mitigation (DDPM) in Thailand warned of heavy rain and flooding in 30 provinces around the country.
Elsewhere in South East Asia, heavy rain and flooding have also affected northern provinces of Laos and Vietnam, where at least 6 people have died as a result.
Meanwhile in Myanmar, the flood situation continues to affect hundreds of thousands in several states or regions, particularly in areas along the Chindwin and Ayeyarwady rivers.
Torrential rain in northern parts of Vietnam began around 12 August, causing flooding and landslides in six provinces. Local media reported that rain reached between 200mm to 400mm in some areas.
Two fatalities were reported in the northern mountainous province of Lao Cai. This is the second deadly flood event in the province in the last few weeks. Heavy rainfall in the wake of Typhoon Nida between 02 and 05 August triggered flash floods and landslides in the province, increasing levels of the Red River, and causing flooding and landslides which left at least 5 dead.
Other fatalities from the recent floods in Vietnam were reported in Dien Bien (2), Thai Nguyen (1) and Thanh Hoa (1) where flooding also destroyed several houses. Landslides triggered by the heavy rain were also reported in the provinces of Yen Bai and Hoa Binh.

The government has mobilized resources and personnel to assist the affected population, according to AHA. Military and police rescue efforts are ongoing with priority given to evacuating people to the safer areas.
