An arrest has been made in the deadly shooting that followed a Kailua festival, while Hawaii heads into a wet few days before clearing up for a big weekend on Maui.

• A 24-year-old woman is in custody on suspicion of second-degree murder after the killing that followed the Kailua Fall Festival; the victim was a 30-year-old man from Kaneohe.
• Prosecutors are expected to decide on formal charges shortly.
• Tropical moisture tied to Hurricane Nolo, spinning west of Kauai, brings showers to Niihau and Kauai today and Oahu tonight, with heavy rain possible on south and southeast mountain slopes by Friday.
• Drier air and trade winds return for the weekend, just as the 99th Maui County Fair runs Thursday through Sunday in Wailuku — four days of food, rides, and exhibits, with $10 adult admission and free entry for the first 2,000 people Sunday.
• McDonald's is testing outside digital ads, including Geico spots, on drive-thru screens at 450 locations — a new revenue stream for the chain and an unwelcome wait for customers.

Outlook: Charges in the Kailua case are expected in the coming days, and clearing skies should give the Maui fair a sunny opening weekend.
