Flash Flood Chaos — Power Cut, Roads Gone

Life-threatening flash floods from Hurricane Lala swept Hawaii, destroying homes, cutting power, and leaving at least one person dead.

Story Highlights

State and county emergency orders activated disaster funds and Guard support before landfall.
National Hurricane Center warned of extreme rain, flash floods, and dangerous surf statewide.
At least one death and homes washed away as flooding hit the Big Island hardest.
Thousands lost power as rain totals of up to 20 inches threatened parts of Hawaii.

Emergency Actions Taken Before The Storm Hit

Governor Josh Green signed a statewide emergency proclamation on August 13. The order activated the Major Disaster Fund and cleared the Hawaiʻi National Guard for use. The proclamation warned that Tropical Storm Lala, nearing hurricane strength, posed a serious threat, especially to Hawaiʻi Island. County leaders followed suit. Hawaiʻi County declared a local emergency under a Hurricane Warning and Flood Watch to speed resources and protect life and property as the storm approached.

State emergency managers issued broad alerts as the track tightened. The Hawaiʻi Emergency Management Agency said damaging winds, heavy rain, and landslides were likely across Oʻahu, Maui County, and Kauaʻi. Officials urged residents to avoid low-lying areas and heed flash flood warnings. The agency highlighted the risk of life-threatening floods and rockslides, a pattern familiar to islanders when slow-moving tropical systems dump intense rain over steep terrain and narrow valleys.

Storm Impacts: Floods, Destruction, And A Confirmed Death

The National Hurricane Center reported Lala strengthened into a hurricane as it neared the Big Island, sending gusty winds, dangerous surf, and torrential rain ashore. The National Weather Service said two homes near Nā‘ālehu were swept away by rushing water. Officials confirmed at least one storm-related death as flash flooding overtook roads and neighborhoods. A flash flood warning covered parts of the Kaʻū District as swollen streams jumped their banks and debris piled up.

Heavy rain totals materialized across windward slopes. State guidance warned that some areas of the Big Island and Maui could see local amounts up to 20 inches, with widespread four to six inches statewide. The National Hurricane Center cautioned that flooding rain impacts were still unfolding across the Big Island and Maui County as bands trained over the same ground. High surf and storm surge added coastal hazards, pushing water into vulnerable shoreline zones and threatening harbors and roads.

Power Outages, Travel Disruptions, And Ongoing Risks

Utilities reported thousands without power as winds toppled trees and floodwaters undercut poles. Reuters noted gusty conditions and localized flooding as the storm core passed south of Hawaiʻi Island, aligning with widespread outage maps and road closures. County notices described Hurricane and High Surf Warnings in effect, with responders staging equipment and shelters. First responders urged drivers to turn around at barricades and avoid drain crossings, where floodwaters rise fast and hide washed-out pavement.

Forecasters kept a tight focus on rainfall rates and landslide risk through the weekend. The National Hurricane Center and state alerts emphasized that the most dangerous outcomes come from water, not wind, in Hawaii’s terrain. Rapid-onset floods sweep cars, rip out culverts, and cut off rural communities. Officials signaled that damage assessments would take time as crews worked through debris, checked bridges, and restored power in hard-hit zones on the Big Island and parts of Maui County.

Policy And Preparedness: What Worked And What Comes Next

Emergency proclamations opened funds and sped coordination. That step let agencies pre-stage the Guard, sandbags, and high-water vehicles before the worst rain bands formed. For families, the lesson is simple: heed watches and warnings, keep go-bags ready, and know your flood zone. For state and county leaders, clearing streams, hardening power lines, and enforcing no-build zones near gulches remain core tasks. Strong preparedness protects life and property when storms like Lala take aim at the islands.
