An NWS employee and several callers from the public reported landslides in Amaluia and a minor landslide in Fatu ma Futi. Over a 24-hour period 5.83 inches of rain was recorded at the WSO Pago Pago. This event caused the roads on both lanes to be blocked in Amaluia (there are only two lanes in american samoa), which left residents from villages west of Amaluia stuck westbound until roads were cleared by Public Works later that evening. A minor landslide in Fatu ma Futi blocked only one lane, luckily only a few minor boulders fell and public works was able to clear it up quickly.
