A storm hit Thong Nai Pan that started on Sunday 26th March and that continued until Thursday March 31st. It was a very unseasonable storm (March is normally the driest month on Koh Phangan).
The whole of the Samui Archipelago was affected. 15,000 tourists were trapped in Koh Phangan, Koh Samui and Koh Tao. All ferry boat services were suspended and all flights to and from Koh Samui were cancelled. The Thai navy were called in to help evacuate people.
21 people died in mudslides on the mainland as villages were swept away by the torrential storm.
Thai Prime Minister Abhisit Vejjajiva visited the worst hit areas today said:
"If you ask people who are familiar [with the situation], they would tell you they never expected this could happen."
As for Thong Nai Pan - there are no reported deaths or injuries, just damage to buildings and infrastructure. The bridge by the Panviman collapsed (it was built without steel reinforcing). The road out of the village in Thong Nai Pan Noi was flooded. The road from Thong Nai Pan to Thongsala lost 2 bridges. This follows a storm earlier this month that damaged the Santhiya speed boat.
