In its 12th statement issued at 5 pm on Sunday, the Weatherman said that the strong cold front from China has already covered upper Thailand and this will cause the weather in the region to remain cold for the next two days until Tuesday.
People in the northern region are advised to take care of their health and to stay warm during the period.
Meanwhile, several southern provinces including Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala and Narathiwat are facing scattered downpours and choppy sea with waves between 2-4 metres high.
People living along the shoreline were told to brace for strong winds and big waves which may pose danger. Fishermen, too, were told not to venture into the sea for their own safety.
