HONOLULU - The Red Cross Hawaii chapter says it's ready. It has just under 100 volunteers positioned around the state, including 30 who flew in from the mainland to help. 

This is what it looked like at Red Cross headquarters on Tuesday in the operations center. It has crews on the ground on Oahu, Maui, and the Big Island, ready to open evacuation centers. "We will be opening seven evacuation centers in Maui at 6 p.m. [on Tuesday] and eight evacuation centers on Oahu at 8 p.m.," says Coralie Matayoshi, CEO of Red Cross Hawaii.

It cautions people to make sure you bring your own supplies if you do check in to an evacuation center, which "are different from shelters in that you have to bring your own food, water, bedding, anything you need," explains Matayoshi.

She urges, "People should be prepared at all times, don't go return things, and take things seriously.
