Joe Biden has declared Hawaii a disaster area after a massive wildfire killed at least 36 people.
The wildfires, driven by a dry summer and strong winds, also forced thousands to flee and destroyed parts of in the historic town of Lahaina – one of the main attractions on the island of Maui.
Some people have been forced to jump into the ocean to escape the blaze.
A mass evacuation effort for stranded visitors and residents is under way, with buses set to pick up people in Kaanapali, north of the town of Lahaina.
Visitors will be taken directly to the Kahului Airport and residents to a shelter in central Maui.
The disaster designation announced by Mr Biden clears the way for federal aid to help the affected communities.
It will allow affected individuals to apply for grants for temporary housing and home repairs, and allow business owners to apply for programs to recover from the disaster, the White House said in a statement.
The US president expressed his condolences during a phone call to Hawaii Governor Josh Green.
