According to Ms. Sukanyanee, temperature will fall by five to eight degrees Celsius from Tuesday through Thursday in the Northeast and by two to four levels in other areas.

Over the Gulf of Thailand, the South, and the Andaman Sea, eastward and southerly winds had been stronger at the same time. In consequence, she predicted that there would be more rain and heavy storms in some of the South’s regions.

In the lower Gulf of Thailand, waves may be two to three meters high, and maybe even higher in areas with heavy rain. In the same time, areas of heavy storms will be one to two meters high and more than two meters high in the Andaman Sea and the lower Gulf of Thailand.

Smaller boats should be confined to the lower Gulf of Thailand during this time, according to Ms. Sukanyanee, and kept away from the Andaman Sea during this time.
