According to RNZI, it was feared the storm would strike Samoa as a large category four system, but it picked up speed and passed Samoa quickly as a category two.
However, strong winds and heavy rains associated with the system still brought down trees and powerlines, caused flooding, and washed away some roads across the country's two main islands.
The largest island, Savai'i appeared to have been the most affected by Amos, with some villages isolated by flooding, landslides and washouts.
