Flash Flood — Manu'a, American Samoa

2019-10-28 · near Ofu, Manu'a, American Samoa

Event narrative

Although 1.53 inches of rain was recorded at the weather service office located on the island of Tutuila, satellite imagery showed strong convective clouds and cold cloud top temperatures indicating most of the rain being dumped over Manu'a. One of our trained spotters called to report that the front of her house was flooded and low cars could not go passed her house to get to the other side of the roadway.

Wider weather episode

An active trough over the island territory ushered heavy showers with the bulk of the rain dumped on Manu'a islands. However, as Manu'a has no official rain gauge reports, we went off of the reports from the usual skywarn spotters.
