Tropical Depression Flossie hit Maui County hardest in the state, according to a preliminary report released this week by the National Oceanic and Atmospheric Administration.
While Flossie's center never made landfall and flooding was "generally minor," Maui County was drenched with the most rain, with an average of 1 to 2 inches and a peak of 5.27 inches, NOAA officials said. Kauai County took the second-most rain, an average of 0.25 to 0.75 inches and a peak of 3.31 inches. Hawaii County was third with an average of 0.25 to 0.75 inches and a peak of 2.86 inches, and the City and County of Honolulu had the least rain, an average of 0.25 to 0.75 inches and a peak of 2.71 inches.
Maui County also withstood the storm's strongest sustained winds, 33 mph in Kahului. The second-highest winds were clocked at 31 mph at Kona on the Big Island, followed by 27 mph in the Waianae Mountains on Oahu and 26 mph in Kekaha on Kauai.
"Gusty winds and lightning accounted for the majority of damage associated with Flossie," the NOAA report said. "Most damage consisted of downed trees, with the majority occurring in Hawaii and Maui counties during the afternoon and evening of July 29."
The reported noted that there were several reports of boulders falling on roads on Maui and Oahu.
"Frequent cloud-to-ground lightning strikes across Maui and Molokai led to numerous power outages, damage to at least one home and one injury (in Haiku) when an individual was shocked inside his home," the report said. "At various times during the event, more than 10,000 homes were without power due to falling trees and/or lightning strikes."
High surf ranging from 6 to 15 feet high struck most islands, with minor coastal inundation reported, NOAA said.
Flossie's closest brush with any Hawaiian Island was with Kauai in the early-morning hours of Tuesday.
Damage reports were not yet available, the report said.
