Thailand Warns of Heavy Rain, Strong Winds in 31 Provinces
The Meteorological Department warns of thunderstorms, strong winds and heavy rain across 31 provinces, with risks of flash floods and forest runoff. Seas in the Andaman and Gulf of Thailand may see waves over two metres during thunderstorms. Detailed regional forecasts outline temperature ranges, wind conditions and rain probabilities for the next 24 hours.
Today's weather: The Meteorological Department announced that 31 provinces will experience thunderstorms, strong winds, and heavy rain covering about 60 percent of the area, with warnings of flash floods and forest runoff.
The 24‑hour forecast issued on 16 October 2069 predicts continued heavy rain in parts of the lower North, Central, East and South. Residents are urged to guard against dangers from thunderstorms, strong winds, heavy rain and accumulated rain that could trigger flash floods and forest runoff, especially on slopes near waterways and low‑lying areas. This is due to a weakening high‑pressure system or cold air mass over the upper North, upper Northeast and the South China Sea, which drives easterly and southeasterly winds carrying moisture from the sea across Thailand and the Gulf of Thailand. In the Andaman Sea and Gulf of Thailand, thunderstorm areas will see waves higher than two metres; mariners should check routes, navigate with caution and avoid sailing in those zones.
