Last week, O'ahu was treated to a 30-minute hail storm, with some stones measuring a record-breaking three inches. Small stones were reported to have fallen on other islands as well.
The storm closed schools and roads, and caused sewage spills, flooded homes, landslides and power outages. A senior meteorologist for the National Weather Service in Honolulu said the storm has been record-breaking in several ways, noting that the highest level of rainfall was 48 inches in Hanalei on Kaua'i.
It's the tail end of Hawai'i's rainy season," he said. "The rain is not all that unusual, but the hail and strength of the thunderstorms are unusual."
Ten-thousand gallons of sewage and storm water overflowed into streams during five separate sewage spills on O'ahu.
Gov. Neil Abercrombie declared a state of emergency for the islands of Kaua'i and O'ahu.
