The episode as NWS ASO wrote it up.

Cyclone Evan made landfall on Upolu on 12/2100Z. Evan was a Category 1 hurricane, and over 10 lives were claimed mainly during flash flooding. People were swept into the strong currents of the flooded rivers and streams, and vehicles were severely damaged by strong winds and tornadoes.

Hurricane (Typhoon), Tutuila

When: December 11, 12:00 AM SST to December 13, 12:00 AM SST
Where: Tutuila forecast zone
Category: 1
Reported by: Official NWS Observations

Hurricane Evan made landfall on Upolu instead of Tutuila as suspected by the Regional Services Meteorological Center- Nadi for the South Pacific region. American Samoa was spared during this episode, hence only gale force winds and strong gusts reached Tututila during the daylight of 12/2100Z to 13/0400Z. No damages or injuries reported.

What these are

Hurricane (Typhoon): A tropical cyclone with sustained winds of 64 knots (74 mph) or more, filed per forecast zone for its wind, and with separate events for its flooding, surge and tornadoes.
