Hawaii power outage map: Tropical Storm Lala knocked out electricity for 250,900 Hawaiian Electric customers statewide at peak - the largest outage in Hawaii's modern history. Rural Big Island residents face months-long waits as a 42-mile Hamakua transmission corridor through inaccessible mountain terrain requires crews to hike in for repairs.

Road closures, flooding, fallen trees, and ongoing severe weather have slowed the restoration process in multiple areas, utility officials said.
