This is the heroic moment rescuers saved a woman from floods by carrying her across a raging river.

The team raced to save the woman after water from two nights of continuous heavy rain engulfed her home in Nakhon si Thammarat southern Thailand on December 3.

Officials said the region was battered by severe downpours and storms throughout Wednesday and Thursday last week. Continuous rain and runoff from the Khiriwong mountain sent torrents of water into low-lying areas.

Officials from Thailand Disaster Prevention and Mitigation Department said heavy rain would continue throughout the south of the country until Sunday but Nakhon Si Thammarat had been the worst affected province so far.

Provincial governor Kraisorn Wisitwong declared all 23 districts of the region a "disaster zone" on Friday morning December 3.

Thailand and other countries in Southeast Asia such as Malaysia, Indonesia and the Philippines are nearing the end of their tropical monsoon rainy season, which lasts until late 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.

Many of the under-developed nations struggle to cope with the heavy rain due to under-investment infrastructure.
