Rescue teams deployed boats to help flood-hit communities in northeast Thailand.

Volunteers paddled to swamped residential areas to deliver aid as floods submerged Loei province on September 3.

Rattana Somsakulrungruang, chairman of the Ruamkatanyu Foundation, said rubber boats and trucks were distributing relief goods to stranded locals along the swollen Loei River.

The river burst its banks on September 1, following heavy rains caused by Typhoon Kajiki and Tropical Storm Nongfah.

Vietnam has also recently been battered by Typhoon Kajiki, which made landfall on August 25, leaving at least seven people dead, one missing, and 34 others injured. Officials said more than 7,000 homes were damaged during the storm.

The Thai Meteorological Department on Sunday said that Tropical Storm Nongfah was moving into Thailand as a strong low-pressure system.

Combined with an intensifying southwest monsoon, the weather system is expected to bring heavy to very heavy rainfall across 43 provinces over the next one to two days.

Authorities warned residents to constantly monitor weather updates.
