Some residents on Maui and Hawaii Island say the storm caught them by surprise.
Powerful storm winds brought down trees and debris, and thousands of Maui residents are currently without power.
Downed trees and a landslide forced Haleakala National Park to close until further notice.
“But the Kipahulu district is open,” said park official Pauline Angelakis. “We encourage everyone to stay safe and be careful while cleanup is going on.”
Over on the Big Island, residents experienced the same “storm shock.”
“The winds just came out of nowhere. A lot of rain, a lot of heavy rain,” said Kamuela resident Charlene Nishida.
The storm devastated her family’s property, with an estimated $40,000 worth of damage.
“Everyone anticipated stormy weather, but not wind force with a magnitude to cause such significant property damage,” she said.
Red Cross volunteers are providing relief for families in Pahoa and Mountain View in Hawaii County, as well as families in Maui County.
