The episode as NWS HFO wrote it up.
A cold front with gusty winds, the second in a week, moved through the Aloha State. This system also brought more precipitation than the previous one. Two injuries during this episode were severe enough to send two individuals to the hospital. As was the case during the earlier frontal passage, the winds brought down power lines, power poles, and trees; damaged roofs, and closed roadways because of debris on the surfaces. The total cost of damages was not available.
