Honolulu's Aloha Tower is opening its observation deck again after years of repairs, good news for residents and visitors who want the harbor view back.

• The deck reopens Thursday, closed for several years while the structure was fixed.
• A centennial party follows Friday night with music, food trucks, deck tours and a drone show.
• The tower has long served as a welcome landmark for cruise ship passengers and fishermen.
• It turns 100 years old, and was once the tallest building in Hawaii.

Outlook: Expect crowds at the harbor this week as the deck reopens and the birthday events run.
