Officials have cancelled all ferry services to and from Koh Phi Phi island from Friday as a precaution in light of tropical storm Pabuk approaching the Malay Peninsula.
Tourists currently on Phi Phi will have to stay there until the boats are allowed to leave port again, probably on Sunday.
Krabi Tourist Police say that all boats heading to the islands in the Haad Nopparat Tara-Mu Koh Phi Phi National Park, including Koh Phi Phi, are banned from leaving ports in the area.
The Department of Disaster Prevention and Mitigation’s Krabi Office issued an order that covers fishing boats, passenger boats and speed boats.
Seatran Ferries, which operates out of Phuket and Samui, have confirmed that they’ve stopped trips to the islands from Phuket in the Andaman Sea or Don Sak on the Gulf of Thailand.
The ban will last until at least Saturday, according to national park officials.
Some national parks in Krabi are also being closed in the interests of tourist safety because of the approaching tropical storm.
The Mu Ko Phi Phi National Park and Mu Ko Lanta National Park were closed from Thursday so travel from island to island is also banned.
Authorities believe they will probably be able to reopen the parks and allow boats to visit the islands again from Sunday.
