Residents in Muang and Tha Sala districts of Nakhon Si Thammarat have been told by officials to brace for flooding after almost 400mm of rainfalls were dumped into the province, particularly in the mountainous Khao Luang area.
Runoffs from Khao Luang have been gushing downhill with force toward the two districts and the airport.
The level of water in Klong Thadee in Lan Saka district has been rising quickly and steadily that it almost breaks its banks.
