As calm seas return to the Andaman coast, the Royal Thai Navy is preparing for the annual influx of tourists, and possibly a fleet of boat people fleeing Myanmar.
The RTN's Third Region, responsible for the Andaman Sea, has stepped up sea and aerial patrols as the annual monsoon fades away from the area.
The end of the rainy season is the beginning of the high season for foreign tourists arriving in Phuket, Phangnga, Krabi, Trang and Satun - a region famed for beautiful beaches and islands.
The main islands have helicopter pads already prepared to help tourists in case of emergency, Vice Adm Surapol Kuptaphan, commander of Andaman-based navy, said on Friday.
But the calmer seas also provide perfect conditions for Rohingya people fleeing Myanmar to set sail from troubled Rakhine state.
Although there are no signs of boat people from Myanmar yet, Vice Adm Surapol said the navy will not lower its guard. Its vessels and aircraft will keep an eye out for "unusual migration", he said, in a clear reference to the Rohingya.
"We are following the fighting, the situation in Rakhine state, as it could lead to migration," he said. "If the refugees want to go anywhere, we will help them.
"Patrols will be more frequent, although there are no reports (of migration)," the admiral said.
The government has a clear policy of not allowing Rohinya boat people to settle in Thailand, but will assist them on their journey to a third country.
The violence escalated in Rakhine last weekend, when Myanmar government troops clashed with Muslim residents, forcing them to flee to the western border with Bangladesh on Tuesday.
Reports that dozens of people were killed in the fighting lead former United Nations secretary-general Kofi Annan, who chairs a commission on resolving the Rakhine problems, to voice great concern at the upsurge in violence there.
