Residents and tourists alike are bracing themselves for what could be the first major hurricane to strike Hawaii in a quarter of a century.
"Be prepared to shelter in place with 14 days of food supplies and water and any other necessities," Gov. David Ige said at a press conference Wednesday.
Stores were selling out of water and generators across all the islands as people prepared for the storm.
"We're getting some bags of rice and of course, some Spam," Melanie Davis, who lives outside Honolulu, told CBS News.
"[I'm] filling up my bathtub with some water, hoping to board up my main windows in time," Big Island shopper Shana Bartolome told KHON.
Officials warned they don't have enough shelter space for everyone and urged people to stay in their homes and only head to a shelter if absolutely necessary.
The last hurricane to hit Hawaii was Hurricane Iniki in September 1992. The Category 4 storm caused billions worth of damage and six deaths.
