Hurricane Lala left a trail of destruction across Hawaii over the weekend, with dramatic videos showing floodwaters washing over roads, tearing through infrastructure and cutting off communities after days of torrential rain and hurricane-force winds.

The storm, which weakened to a tropical storm on Sunday as it moved west away from the islands, has damaged homes, destroyed transportation links and left hundreds of thousands of residents without electricity.

The latest reports from The Weather Channel say that the heaviest rainfall from Lala was recorded at Laupāhoehoe on Hawaii Island's northern coast, where 42.69 inches fell between Friday and Sunday. More than 31 inches of that total came within 24 hours. Nahuku recorded over 35 inches of rainfall, while Hilo International Airport received nearly 10 inches. The deluge contributed to severe flooding, mudslides and fast-moving torrents that overwhelmed roads and streams in parts of Hawaii Island.

Governor Josh Green said at least 100 homes were damaged or destroyed during the storm, according to Reuters, while state officials reported significant infrastructure damage across multiple islands.

Videos released by the Hawaii Department of Transportation showed floodwaters overtaking roadways, while emergency officials reported extensive washouts in some of the hardest-hit areas.

On Hawaii Island, local reporting from Maui Now said that several occupied homes were "inundated" by floodwaters, prompting search-and-rescue operations involving local agencies, the National Guard and the Coast Guard.

Residents have been urged to stay off the roads as emergency crews assessed hazards and began recovery operations.

'Deadly' Hazards Remain, 178,000 Without Power

Power outages remained one of the most significant ongoing consequences of the storm.

In its latest update on Sunday evening, Hawaiian Electric told Newsweek that approximately 178,400 customers remained without electricity across Hawaii. About 126,500 outages were reported on Oahu, 44,900 on Hawaii Island and roughly 7,000 in Maui County.

The utility warned customers in the most heavily damaged areas to "prepare for extended outages" as repair crews continue to assess damage and repair critical infrastructure.

Hawaiian Electric said restoration efforts are focused first on inspecting and repairing major transmission lines, which serve as the backbone of the state's power grid. Flooding, unstable ground, downed trees and difficult terrain have complicated access to damaged equipment in several locations. It said that it has "requested personnel from partner electric utilities from the mainland to help expedite post-storm restoration," with about 100 crew members expected to arrive on Tuesday and begin work on Wednesday.

Hawaii’s Emergency Management Agency has warned that, even though the storm's center has moved away from Hawaii, "numerous safety hazards exist including dangerous debris, contamination risks and electrical hazards" due to severely flooded areas, debris and downed power lines.

At the storm's peak, more than 200,000 customers lost power statewide, and at least three hospitals were forced to operate using backup generators, according to CNBC News.

Deaths and Rescues Under Investigation

Questions remain about the storm's human toll.

Officials reported a fatal vehicle crash in the South Point area of Hawaii Island during the height of the storm. However, Green said authorities were still determining whether the death was directly related to Hurricane Lala. According to CNN, Green also said another person was found dead during the storm, but investigators haven’t yet established whether or not that death was connected to the extreme weather conditions.

Storm Track and Outlook

Lala briefly reached Category 1 hurricane strength Saturday, with maximum sustained winds of 75 mph, before weakening to a tropical storm as it tracked westward past the Hawaiian Islands. The storm's eyewall skirted Hawaii Island without making landfall, but its large wind field and rain bands still produced damaging conditions across the state.

According to the National Hurricane Center, Lala was moving west toward Kauai County on Sunday with sustained winds near 65 mph and was expected to continue moving away from Hawaii. Forecasts indicated the center of the storm should clear the island chain by Monday morning, although flooding, landslides, rough surf and power outages could continue well after the storm's departure.

Despite recovery efforts beginning to ramp up, with washed-out roads, damaged bridges, widespread debris, and ongoing power outages, the full extent of Lala's impact won’t be fully understood for several more days.
