Prime Minister Anutin Charnvirakul on Tuesday declared a state of emergency for Songkhla province, which includes southern Thailand’s biggest city, Hat Yai, citing the “unprecedented severity” of the flooding that has caused widespread damage.

Heavy monsoon rain overwhelmed parts of Thailand, Malaysia and Indonesia this week, killing more than 300 people and leaving thousands stranded, many on rooftops awaiting rescue.

Flooding from days of intense rain has killed at least eight people in southern Thailand and forced thousands into evacuation centres in neighbouring Malaysia, officials said on Monday, as authorities ramped up efforts to provide shelter and aid.

"Thai authorities have declared Hat Yai a red-flag disaster zone following heavy rainfall and widespread urban flooding. The flooding in parts of Hat Yai has led to power disruptions and limited access to food and essential supplies," MFA noted.

Historic flooding in Songkhla Province in southern Thailand has forced the SEA Games 33 host country to activate contingency plans, moving 10 sport events to Bangkok and Chonburi.

The death toll from flooding in southern Thailand has reached at least 145, the Department of Disaster Prevention and Mitigation said on Friday, as receding waters started to reveal devastating damage across the region.

The government coordination centre for flood relief has been established at the Don Muang Royal Thai Air Force Base, with C-130 aircraft on duty to transport supplies and personnel to the severely flooded South five times a day.

MANILA, Philippines–Boxing and nine other events of the Thailand SEA Games originally scheduled for Songkhla have been moved to Bangkok due to massive flooding that hit the southern province. Local reports said that the conditions of the venue coupled with potential risk of disease outbreaks prompted the host country to move those disciplines,
