Ms Angkana was reported missing on Thursday morning, when relatives and friends could not find her.
Today an official told The Phuket News that Ms Angkana had contacted her family.
Rescue teams continued to search today inside the ruins of the warehouse store, but still no bodies have been found.
Heavy rain overnight might have brought some relief to the firefighters working on putting out smoldering embers, but a lot of the site is covered by iron roofing, and the hot embers are underneath lots of debris.
The store, located on around 30 rai of land, caught fire in spectacular fashion on Wednesday night (October 16) around 9.40pm, engulfing the entire store in around 10 minutes. So far there have been no confirmed reports of any injured or dead, despite initial concerns from the public that people were trapped inside.
