BANGKOK — Thailand is bracing for a week of heavy rainfall and potential flooding across multiple regions, including Greater Bangkok, the North, Northeast, and East, due to the intensified monsoon trough influenced by Typhoon Ragasa in the Pacific Ocean. The Meteorological Department issued warnings from Sunday through Saturday, urging residents in low-lying areas to prepare for possible flash floods and runoff.

Flooding Claims Three Lives Across 12 Thai Provinces

Somkuan Tonjan, director of the Meteorological Department’s weather forecast division, confirmed that while Typhoon Ragasa is not directly approaching Thailand, it has amplified the monsoon trough over the lower North, upper Central Plain, and upper Northeast. This will result in persistent heavy rain in provinces including Bangkok, Chanthaburi, Trat, Mae Hong Son, Tak, Ubon Ratchathani, and Amnat Charoen.

The Department of Disaster Prevention and Mitigation reported that flooding has already affected approximately 221,000 people across 13 provinces: Phitsanulok, Phetchabun, Phichit, Nakhon Sawan, Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Suphan Buri, Ayutthaya, Pathum Thani, Nakhon Pathom, and Chachoengsao. While most floods stem from river overflows, Uthai Thani and Chachoengsao experienced inundation due to direct heavy rainfall.

Residents are advised to avoid travel during storms, secure property, and heed official updates.

The government emphasizes preparedness and coordination among local agencies to mitigate impacts.
