A powerful storm damaged rooftops, felled trees and knocked out power to thousands of homes around Oahu on Friday as a fast-moving cold front swept over the island chain.
The National Weather Service issued a series of warnings and advisories throughout the day as the storm traveled eastward.
Kauai bore the early brunt of the storm, prompting the weather service to issue a flood advisory effective through the early evening.
Over the six-hour period ending at 5:45 p.m. Friday, several locations on Kauai experienced heavy rainfall, including Mount Waialeale (1.73 inches) and North Wailua Ditch (1.7 inches).
By late afternoon the storm had reached Oahu, sending first responders and utility crews into emergency action islandwide.
Police and firefighters responded to numerous weather-related calls through the evening, including downed trees on Waialua Road; fallen power lines in Kaimuki, Wahiawa and other locations; and several blown or damaged roofs on the Windward side.
The storm also left several thousand Hawaiian Electric Co. customers without service starting in the late afternoon.
Over a five-hour period starting at 3:30 p.m., HECO repair crews responded to nine significant outages in areas including Nuuanu-Pali (425 customers), Kaneohe (1,670), Kaneohe/Kailua/Maunawili (1,290), Wahiawa (2,490), Waialua (1,840), Hawaii Kai/Waimanalo/ Kailua (1,500), North Shore/Waimea (840), Kahuku (410) and Kaneohe from Castle High School to Aikahi (2,350).
Most of the outages were resolved in less than an hour.
The state and Hawaii County canceled all camping permits for Waimanu on Friday because of the weather.
The Department of Land and Natural Resources’ Division of Forestry and Wildlife and the Hawaii County Civil Defense also closed the Waimanu trail in North Kohala Friday.
The closure is expected to remain in effect through the weekend, according to a news release by DLNR.
The state also closed the Kalalau Trail in Kauai’s Na Pali Coast State Wilderness Park.
Forecasters predict that the wind will shift northwest and showers will diminish after the front pushes through. Cool and dry weather is expected behind the front on Sunday, with a relatively dry tradewind pattern resuming early next week.
Meanwhile, several warnings remain in effect.
A blizzard warning and high-wind warning are posted for Mauna Kea and Mauna Loa until 6 p.m. Saturday.
Hurricane-force winds of 55 to 90 mph, with gusts over 130 mph, are expected. Forecasters said up to a foot of snow with "much higher drifts" is expected Friday night and Saturday.
