Thailand Reservoir Breach Risk Sparks Evacuation

In Thailand's eastern province of Rayong, an emergency evacuation was mandated on Monday for residents near the Khlong Ra-Ok Reservoir due to structural concerns. Cracks were discovered on the reservoir's wall and around the spillway, prompting immediate warnings for areas including Thung Khwai Kin and Nam Pen. The reservoir had surpassed its capacity, reaching 117 percent with 23.5 million cubic meters of water, necessitating the full opening of outlet gates to reduce pressure.

This incident occurs as the nation grapples with widespread flooding following days of intense rainfall. While some rainfall is forecast to ease in Bangkok and surrounding areas on September 28 and 29, thunderstorms and isolated heavy downpours remain likely across 70 percent of the region. The North, Central region, and East are particularly vulnerable to flash floods, overflowing rivers, and landslides.

Authorities are enacting emergency relief measures, including deploying field kitchens and mobile water-purification units in Bangkok. Preparations are also underway for recovery, with potential financial assistance and compensation for damaged properties being coordinated. Small boats are advised to stay ashore in the upper Andaman Sea and Gulf of Thailand until September 28 due to potential waves exceeding three meters during thunderstorms. Accumulated water and runoff continue to pose flood risks in many provinces, including Bangkok, Nonthaburi, Pathum Thani, Samut Prakan, Rayong, Chanthaburi, and Trat.
