The wider storm
A strong high pressure system centered to the south of Fiji moved a trough from the south of American Samoa onto the territorial islands on May 16th through the 18th. This stationary weather pattern lead to over 9.68 inches of rain recorded at WFO American Samoa. This includes 3.55 inches that fell in two hours on the afternoon of the 18th. This intense rainfall led to widespread flash flooding throughout the territory. Multiple landslides were also reported due to the intense rainfall on saturated soils.
