SUNSET BEACH (HawaiiNewsNow) - It could be the biggest surf Hawaii has seen in the past 40 years.
Although the surf calmed down a bit on Sunday, some North Shore of Oahu residents prepared for the worst.
Sunset Beach pumped up the hundreds who came to see the big wave spectacular.
"We saw that they were big on Surf Net News and thought we'd check it out," Ewa Beach resident Scott Brown said.
On Sunday, waves were around 15 feet. But on Monday, they're predicted to be as tall as 50 feet.
"This looks to be a very, very large event, beyond what we consider to be a classic North Shore winter surf, it could be hazardous, we could see some damage to our coastal areas, hopefully not to homes, but we could see road closures," City Department of Emergency Management's John Cummings said.
That's what the Delgado's are worried about.
"It's enough to scare you, you don't know what's actually following it," North Shore resident Paula Delgado said.
They have a breathtaking view of a spot they call, "Leftovers." But sometimes, looks can be deceiving. the waves have forced them out of a home before.
"Its pretty dangerous, but sometimes, human no understand that danger is always there," Paula said.
The Delgado's have stocked up on emergency supplies. They feel prepared in case the waves come crashing towards them once again.
"We feel we up if the water come, the water going under and around the house, so we just sit here and watch," Paula's husband, Sam said. "Let nature take care."
