Wider weather episode

From May 5th through May 9th, a ridge from the south of the islands interacted with an equatorial trough to the north. This created high winds on the 6th through the 8th with gusts reaching around 55 mph at WSO Pago Pago. Total rainfall recorded at WSO Pago Pago was 12.62 inches during this time, including 4.93 inches which fell from 8:50 PM SST to 11:50 PM SST on the 9th. High winds also created minor coastal flooding and erosion along the southern and eastern coast lines. As American Samoa received well above average rainfall throughout the year along with this event, landslides occurred along some parts of the islands.
