Flash floods and mudslides strike Patong in Phuket's worst flooding in 50 years

Early Monday morning, severe flash floods and mudslides swept through Patong, Phuket, marking the area's most significant flooding event in 50 years.

Heavy overnight rain triggered sudden mountain runoff, sending torrents of water, mud, and large rocks crashing into residential and commercial zones, according to The Phuket Express. The Na Nai community was particularly hard hit, with extensive damage reported to shops, vehicles, and local properties, according to Thai-language reports from MGR Online.

This localized disaster in Phuket coincides with broader weather alerts across the region. The Office of the National Water Resources (ONWR) and the Meteorological Department have issued urgent warnings for 14 southern provinces, forecasting continued heavy rain and flash flood risks through October 29.

What this means for expats and travelers

If you live in or are visiting the southern islands, the immediate risk of sudden runoff remains high.

• Avoid hillside roads: Mudslides have already brought large rocks and debris into populated areas like Soi Na Nai. Avoid driving near steep inclines until the weather clears.
• Document property damage: If your vehicle or home was damaged in the Patong floods, take photos immediately before beginning cleanup for insurance purposes.
• Monitor the wider south: If you are in one of the 14 southern provinces under the ONWR warning, remain alert for sudden runoff. The Department of Disaster Prevention and Mitigation also warns of high sea levels compounding flood risks between October 27 and 31.
• Expect travel delays: Localized flooding frequently disrupts transit to and from regional airports, as well as ferry services to nearby islands.
