Scattered thunderstorms with gusty winds, some hail and possible lightning strikes are likely in northern areas of Thailand from May 8-10, the Meteorological Department said on Monday.
The department said the weather conditions are being influenced by another moderate high-pressure system coming from China and extending over the upper Northeast Region of Thailand and the South China Sea from Monday.
At the same time, southerly and southeasterly winds are bringing humidity from the Gulf of Thailand and the South China Sea to the upper part of Thailand, where hot to very hot weather is persisting.

From May 8-14, the low-pressure cell over the lower Bay of Bengal will likely develop into a tropical storm, which is expected to move from the middle of Bengal Bay and upper Andaman Sea to the coastal area of Myanmar. This will lead to a stronger southwesterly wind prevailing across the Andaman Sea and Thailand. Heavy to very heavy rain is possible in some areas, the weather office said.
The upper Andaman Sea will see waves 2-4 metres high and 4m high in areas with thundershowers. Waves in the lower Andaman Sea will be about 2m high and over 2m in areas with thundershowers.
All vessels should proceed with caution and small boats working in the upper Andaman Sea should remain ashore, the department said.
