Flash flooding and heavy rain has inundated tens of thousands of homes in southern Thailand, including in some tourist areas.
The flooding has hit the far south of the country, particularly the southern-most provinces of Yala, Pattani, Songkhla and Narathiwat.
Thousands of homes have been flooded and mudslide alerts have been issued.
Authorities are hopeful that water will recede on Tuesday as the rain eases.
Last week the official death toll from months of flooding in the country rose above 800, with King Bhumibol Adulyadej saying the damage caused by the waters was the "worst ever".
The Gulf of Thailand has seen huge seas over the past two weeks, with islands like Koh Samui also affected by large waves and rain.
West coast tourist hotspot Krabi has also recorded heavy rain and residents have been warned of landslides.
Some areas affected are still recovering from flash flooding and landslides last March.
At their height, Thailand's worst floods in half a century affected 65 of 77 provinces in the low-lying nation, deluged hundreds of thousands of homes and forced the closure of large industrial parks, disrupting global supply chains.
