Bangladesh/Myanmar: Deep depression to hit Chittagong May 29-30

Event

A low-pressure system in the Bay of Bengal has developed into a deep depression (with maximum sustained winds of 56 km/h [35 mph]), according to the Indian Meteorological Deparment, and is forecast to make landfall along the coast of Myanmar late on Tuesday, May 29 (local time), or early on Wednesday, May 30. Among the areas forecast to be most severely affected are west-central to northern Myanmar (including Mandalay) and Chittagong district (Bangladesh).

The storm has already brought significant rainfall to parts of western Myanmar in the last few hours, including between Sittwe (Rakhine state) and the capital, Yangon. Notably, approximately 228 mm (9 in) of rain has fallen in Maubin, and 77 mm (3 in) in Yangon. At least one person has been killed and another injured in Rakhine state as of May 29. Heavy rainfall, high winds, and consequent flooding, landslides, transportation disruptions, and power outages are possible in the coming hours in affected areas.

Context

Torrential rains, flooding, and landslides affect Bangladesh on a yearly basis during the rainy season that spans from April to October.

The monsoon season in Myanmar typically last from May to October; flooding is a common occurrence in Myanmar from June through August as heavy rain often causes rivers to overflow.

Advice

Individuals present in affected areas are advised to keep abreast of the situation, to avoid areas directly hit by flooding, and to adhere to any orders issued by the local authorities or their home governments. Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult - and that floodwater may contain wastewater or chemical products; all items having come into contact with the water should be disinfected and all foodstuffs discarded. Be aware that the risk of contracting water- and mosquito-borne diseases tends to rise after periods of heavy rains.
