Power crews are slowly winning back the grid after Hurricane Lala, but tens of thousands of people in Hawaii are still in the dark — and some may wait weeks.

• Hurricane Lala knocked out power for more than 200,000 customers when it hit the Big Island.
• Four days later, 37,000 are still without electricity.
• Hawaiian Electric expects 95% of customers back on by Friday.
• The hardest-hit parts of the Big Island face the longest wait, with full restoration not expected until September.

Outlook: Most people should have power back within days, but damaged rural areas on the Big Island are looking at weeks more without it.
