The Department of Meteorology and Hydrology has announced that the southwest monsoon is likely to enter Myanmar’s delta regions within the next two days, while isolated heavy rainfall may occur in Tanintharyi Region and Mon State.

According to the department, strong monsoon conditions are currently prevailing over the Andaman Sea and the southeastern Bay of Bengal, while the remaining areas of the Bay of Bengal are experiencing partly to moderately cloudy conditions.

As a result, until May 20, widespread rain and thunderstorms are expected in Tanintharyi Region, Karen State, and Mon State; scattered rainfall is forecast in Yangon Region, Bago Region, Ayeyarwady Region, and southern and eastern Shan State; while isolated rain and thunderstorms are likely in the remaining regions and states. Tanintharyi Region and Mon State may experience localized heavy rain, with a 100 percent chance of rainfall.

The department also stated that cloud formations are currently developing over Yangon Region, Tanintharyi Region, Karen State, and Mon State. Areas along the movement paths of these storm clouds may experience strong winds, thunderstorms, lightning, hailstorms, and heavy rainfall.

In Myanmar waters, occasional squalls are expected over the delta areas, the Gulf of Mottama, along the Mon-Tanintharyi coastline, and offshore seas, with moderate to rough seas possible. During squalls, surface wind speeds may reach 30 to 35 miles per hour. Wave heights in the delta region, Gulf of Mottama, Mon-Tanintharyi coastal areas, and offshore waters may reach about seven to nine feet.

Meanwhile, moderate sea conditions are expected in the remaining Myanmar waters, with wave heights along the Rakhine coast and offshore seas likely reaching about five to seven feet.
