The heavy rains on Tuesday led to swollen streams on two islands and a pair of major rescues.
Several teens were swept away at Ice Ponds on Oahu.
On Maui, 12 hikers needed to be rescued after getting caught in a flash flood.
They were hiking in the bamboo forest off Hana Highway, which is about a three-mile hike through dense forest with streams and a waterfall.
The hikers said they were well into their journey when the flash flood warning was first issued, so they had no idea what they were about to experience.
One of the hikers, Justin Lopez, captured the experience on his Go Pro camera
When the stream started swelling into a raging river two groups of hikers joined forces to get to higher ground.
“Probably took like three to five minutes to go from just a normal nice day with friends to a raging flood, just, we, it was scary. Everybody was pretty scared that day,” Marty Quirk said.
But Quirk says there was a group of three teenage girls — who they were unable to get to — who were hanging onto a ledge near the waterfall and panicking.
Quirk then climbed a 30-foot tree in order get cell phone reception so he could call for help.
He said within ten minutes rescue crews came to airlift them out to safety.
Besides a few scrapes and bruises, all of them were able to walk away in good shape.
They wanted to send a special thank you to the Maui Fire Department for coming to their rescue.
