Parts of Hawaii continue to be battered by wind and rain, the lingering effects of Hurricane Iselle.
Thousands of people on Hawaii’s Big Island have been left without power.
Iselle has moved off westwards and weakened from a hurricane to a tropical storm.
But Julio, a storm recently upgraded to hurricane status, is close behind.
The US National Weather Service says Julio could make landfall on Sunday (August 10).
Such extreme weather is rare for Hawaii. The archipelago has not taken a direct hit from a hurricane since 1992.
The National Weather Service says the islands have never faced two such strong storms back-to-back.
Officials have opened storm shelters across Hawaii and urged residents to stock up on emergency supplies.
