Markets and roads were submerged in flood water as rain poured along the Thai-Myanmar border over the weekend.

Water levels rose on the Sai river causing it to overflow in the Mae Sai District, Chiang Rai Province on Sunday September 11.

Stalls at the Sailomjoy Marke and nearby homes were flooded with vendors carrying their goods to dry ground.

Homes in the Hua Fai , Koh Sai and Ban Pha Taek, Wiang Phang Kham, Doi Nang Non, and other areas were also flooded.

With the weather still overcast and more rain expected, officials set up a disaster recovery centre to help victims.

Chaiyon Sisamut, Mayor of Mae Sai Subdistrict Municipality, ordered officials to check the damage that occurred as well as deliver rice to stranded families. He instructed fire trucks to clean the road and shops near Sailomjoy market to return to normal as fast as they can.

Thailand and other countries in Southeast Asia, such as Malaysia, Indonesia and the Philippines, are in the middle of their tropical monsoon rainy season, which lasts from May or June until November.

Soaring temperatures reaching 35 degrees Celsius are often followed by powerful tropical storms with thunder, lightning, rain and flash floods which cause rivers to flow faster and become dangerous.

This year, meteorologists have blamed climate change for the sustained heavy rain, which has been hitting the Thai capital and provinces around the country causing severe floods for several weeks.

Warnings of strong wind and storms were also issued for regions across the northeast, east, and south. Thailand's Center for Climate Change and Disaster claimed the coming months could see heavier, longer rainfalls, due to 'climate change'.

Local media reported that the country has this year seen 'an unusually sustained and persistent rainy season'.
