Mayor Rick Blangiardi confirmed that first responders had conducted 233 rescues during the storm, with no reported fatalities.

Gov. Josh Green noted that approximately 5,500 people had been evacuated from the North Shore communities.

The evacuation came as Hawaii experienced its worst flooding in 20 years, with roadways and buildings remaining submerged in some areas.

Dam Conditions Stabilize

The Wahiawa Dam, which had been trending up toward 85 feet over the previous day and a half, stabilized overnight at 81.83 feet by 6:30 a.m.

Officials were taking readings every two hours to monitor the critical infrastructure.

Gov. Josh Green explained that the dam represented a significant safety concern, stating "At 85 feet, everyone's got to be out of there" and warning that "At 88 feet, it becomes perilous".

Green noted that at 90 feet, there would be serious risk of "the water going over the top of the dam and cause damage and, God forbid, cause a catastrophic failure of a dam."

Despite the stabilization, authorities maintained vigilance as more rain was expected across the island on Saturday, bringing the continued risk of additional flooding.

Emergency Response Deployed

More than 200 National Guard members were activated during the storm to assist with rescues, road closures, door-to-door checks, and other public safety needs.

Guard leaders were specifically positioned at Wahiawa Dam to provide "extra readings and extra eyes" as officials closely monitored conditions.

On Saturday, Guard members trekked through mud to check on residents in the outskirts of Waialua, demonstrating the extensive emergency response efforts.

Randy Collins, director of the Department of Emergency Management, reported that most shelters were closing Saturday evening.

Shelters at Kaneohe District Park and Nanakuli High and Intermediate would remain open for residents who continued to need services.

Dam Safety Review

Hawaii has 122 dams statewide that are monitored by the Department of Land and Natural Resources' Dam Safety Program.

Governor Green announced that the state will reassess its overall approach to dam safety following the recent flooding crisis.

The governor specifically mentioned plans to add more visual monitoring, such as cameras, and to accelerate structural improvements like spillway projects.

Green stated "It's just too big a deal to see a disaster like that happen" and emphasized the need for "extra resources, both visually — we're putting more cameras on them — and also structurally."

Green noted that he has already spoken with Department of Transportation Director Ed Sniffen about advancing spillway work "just to make it safer."

Federal Support & Damage

Green confirmed that the White House reached out to him "preemptively," describing the federal response as supportive as teams prepare to assess the extensive damage.

Authorities emphasized that "we're not out of the woods yet" despite the improving conditions.
