Floods have receded in southern Thailand leaving streets strewn with debris as cleanup efforts begin.

Footage shows the devastation as the deluge subsided, exposing the rubbish-covered road at the Kim Yong Market in Songkhla province.

Vendors hauled their muddy food carts and furniture onto the sidewalk, and salvaged what valuables they could from the carnage.

Locals reported that water and electricity had not yet been restored, while a foul stench hung in the air, prompting calls for authorities to speed up the cleanup.

Some roads around the market were also filled with mud, waste, and debris swept away by the floods.

The death reached more than 100 as the catastrophic floods, described by Prime Minister Anutin Charnvirakul as 'the worst flooding in 15 years', swept through southern Thailand.

Police Lieutenant General Trairong Phiewphan, Deputy Inspector General of the Royal Thai Police, said 104 deceased victims were sent for identification on Thursday evening.

Soldiers, volunteers, and local government units have also been mobilised to hasten relief efforts, but they were hobbled by limited phone signal in the area.

The Thai military has sent some 200 boats, 20 helicopters and its lone aircraft carrier, the Chakri Naruebet, to deliver essential supplies and carry out rescue efforts.

Songkhla's Hat Yai district was among the worst-hit areas, which saw a record 13 inches (335 mm) of rain in a single day on November 21.

Songkhla Governor Ratthasart Chidchoo on Monday declared all 16 districts disaster zones and ordered the immediate evacuation of children, the elderly and the sick.

On Sunday, high-clearance trucks arrived to evacuate more than 400 tourists from flooded hotels across the city.

The Disaster Prevention and Mitigation Department said that floods hit nine southern provinces, affecting some 1,128,284 households and 3,221,958 people.

The Southern Eastern Meteorological Centre said a strong monsoon trough was causing the heavy rainfall, which was expected to ease this week.

Thailand and neighbouring countries in Southeast Asia are in their annual monsoon rainy season which sees soaring temperatures followed by powerful rain storms in the afternoon leading to widespread flash floods.
