From the Storm Events narratives, unedited.

Hurricane Amos passed near American Samoa during the early morning hours on the 23rd of April. The strongest wind speed and highest gusts were reported from the NOAA ESRL in Matatula, with winds peaking to near 65 MPH Gusts 74 MPH. Several residents on Tutuila self-evacuated their families to avoid storm surge and coastal inundation. There were downed plantations, fallen trees and damaged outdoor kitchens reported from the village of Fitiuta in Manu'a. The south-facing shores of all Islands were heavily impacted by strong swells and dangerous surfs, and coastal erosion was noticeable along the Nuuuli/Coconut Point which impacted the road forcing motorists to drive on only one lane. No injuries or fatalities reported.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
