My family has been to Maui/Lahaina at least 15 times over the last two decades. A truly special place. Out four kids have such fond memories of Maui and Lahaina and Ka'anapali beach. So tragic to see the destruction there and the slow rebuilding.
Last I heard the blame was being laid on the local power company workers. Apparently lines were left down on the ground while repairs were being made and the winds picked up while workers were at lunch. The wind speeds were above the power company's upper limit for leaving lines on the ground. The high winds allowed sparks associated with the live lines to catch the surrounding vegetation on fire and whoosh, there it went. Do I have the facts roughly correct here?
