Beach erosion and runoff were observed along the west, north and northeast facing reefs. Maximum winds of 41G59 mph were recorded at the Weather Service office and maximum winds of 58G81 mph were recorded at the NOAA Earth System Research Laboratory (ESRL) on Cape Matatula of Tutuila.

Downed banana trees werereported, with little to no damages along the north facing coast of Tutuila and Manua. Due to the lack of data and observationsduring TC Garry, the Weather Service Office recorded a sustained wind of 33 mph with gusts at 44 mph on 22/1255Z. Noinjuries reported

  • January 10 - 24, 2016 - Storm surge, swells and surf associated with Severe Tropical Cyclone Victor impacted American Samoa. - Hurricane Victor generated dangerous swells and surfs...and storm surges that have impacted the shores of American Samoa. The storm surge damaged homes and personal properties in low-lying areas near the shores. Also, the storm surge triggered coastal erosion mainly along the east and south facing shorelines of Tutuila. The power-line, rock-walls, family yards and a private boat ramp were damaged in the Nuuuli/Coconut-Point beach area. There was no injury or fatality reported. Monstrous swells and storm surge generated by Hurricane Victor thrashed the coastlines of American Samoa...especially along the east...south and west facing reefs. Hazardous surfs peaked to 25 feet during Friday night and Saturday, however, resident on Tutuila and Manu'a observed several threatening sights of storm surges, coastal inundations and coastal erosions.
  • April 13 - 25, 2016 - 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.
  • December 23, 2016 - January 1, 2017 - A convergence zone associated with Tropical Depression 05F caused heavy rain and thunderstorms over the archipelago, which lead to severe flooding in low lying areas.[4]
  • February 8 - 13, 2017 - 09F[4]
  • February 17 - 23, 2017 - 12 & 14F

  • May 9 - 12, 2017 - Ella[4]
  • December 16 - 19, 2017 - Tropical Disturbances 02F and 03F formed within a monsoon trough, just to the south-west of Samoa.[22] They both moved south-eastwards to the south of Fiji and dissipated, however, the monsoon trough associated with the disturbances caused strong winds and heavy rain over the archipelago.[22][23]
  • February 8 - 11, 2018 - Tropical Cyclone Gita combined with an active monsoon trough generated destructive winds and torrential rainfall between thehours of 4 AM to 2 PM. At the peak of the tropical storm before 8 AM, the Weather Service Office and most of AmericanSamoa loss power. The NOAA Earth System Research Laboratory (ESRL) Office in Matatula recorded 64 kt gust 85 kt, andthe radiosonde data reported 59 kt around 6 AM. Tropical Cyclone Gita caused widespread damages to homes, private andpersonal properties, government facilities, roads, electrical poles and wires, phone lines, and plantations across AmericanSamoa. About 965 people including children evacuated to 12 shelters on the island of Tutuila. Numerous mudslides, flashflooding in small streams and low-lying areas were results of heavy rainfall. Heavy runoff swept debris and water into homesnear valleys and small streams area. Several banyan trees and most breadfruit trees were uprooted.A cargo shipping boat in Manu'a, Uila o le Sami, sank in Ta'u. Another similar incident occurred where an alia boat sank inFagaitua bay but was later recovered by the owners on the following day. A storm surge up to 2 to 4 feet swept debris over themain road and beach area along the northwest through northeast shores of Tutuila, Aunuu and Manu'a. No fatalities

2020 edit

  • December 23 – 30, 2019 – A monsoon trough associated with Tropical Cyclone Sarai caused strong north-northwest winds In December 2019, an active monsoon trough, coupled with a developing system that evolved into Tropical Cyclone Sarai, prompted the issuance of a High Wind WARNING for American Samoa. Although Tropical Cyclone Sarai passed well southwest to south of American Samoa, the strong north-northeast winds and flooding rain caused downed vegetation and landslides.
  • February 14 – 23, 2020 – An active monsoon trough was near-stationary over the Samoan Islands and spawned Tropical Disturbance 07F, Tropical Disturbance 08F as well as Tropical Cyclone's Vicky and Wasi. In association with these systems,


From the aforementioned systems, the most widespread damage over American Samoa was the strengthening of TD09F to Tropical Cyclone as it migrated southeast. This system damaged homes and caused power outages across the territory when TC Vicky was located about 84 nautical miles Southwest off Tutuila island, with maximum 1-min sustained winds of 40 knots (46mph/74km/h) and gusts reaching 65 knots (75mph/120km/h). It placed at least 300 people in emergency shelters. The coastal inundation washed over homes in the far east village of Onenoa, displacing about 50 people. Flash flooding was widespread, especially as grounds were already saturated from previous days. Numerous trees were downed, and air transportation was suspended due to the closure of the ports. The closure of the airport and seaport was not only due to TC Vicky, but in response to the issuance of a Tropical Storm Watch, as Tropical Depression TD10F was forecast to quickly strengthen and become Tropical Cyclone Wasi.
