Yesterday, May 13, marked the first day of Thailand’s rainy season. A low pressure cell from upper Vietnam is expected to cause heavy rain and potential flash flooding in 36 provinces in the kingdom.
The Meteorological Department advises people to be aware of the dangers caused by heavy rainfall. Sailors, especially on the Andaman Coast, should expect tall waves and thunderstorms and should proceed with caution.
The rain is expected to reduce levels of dust and smog significantly.
