The warnings follow a report by police in Nakhon Ratchasima’s Wang Nam Kheow district Thursday that local resident Udon Sodmai drowned in a flash flood while out searching for food in the forest during heavy downpours.
The warnings are being broadcast via the park’s internal radio system.
The national park’s chief, Krissada Homsamud, Thursday said officials were keeping tabs on the number of trekkers and recording their cell-phone numbers before allowing them to go hiking for safety reasons.
“We have rapid-deployment teams on standby. If anything happens, rescue operations will start immediately,” he said.
