HANAUMA BAY (HawaiiNewsNow) - It happens every few years when drenching rains overwhelm Hanauma Bay. It happened again when runoff from Monday's heavy downpours cut the shoreline to pieces and forced the popular tourist spot to hang out the closed sign.
"We definitely wanted to come and snorkel and see all the wildlife and coral. It's a bummer that it's closed," said Brittny Fisher, whose family is on vacation from Chicago.
"When we get the heavy rains like the episodes we've had over the last couple of days, we end up with ravines being created across the beach," Hanauma Bay manager Alan Hong said.
The excess water washed away sand that covers a concrete swale and left a spider's web of ditches - some steeper than others.
Hong was concerned the curiosity of onlookers might get the better of them and they'd venture a little too close to the edge.
"These ravines are fairly deep and fairly sharp edged and they collapse whenever anybody walks near them," he said. "When we have heavy rains like we had over the last couple of days it just overwhelms the drainage system and we end up with water cascading down the cliff and then across the beach and then straight into the water."
The foul weather also wreaked havoc on the Ala Wai Golf Course.
Tee times were cancelled for 400 players.

But in terms of sheer numbers, the biggest weather casualty was Hanauma Bay.
If the sun was out it would have pulled in up to 4,000 people.
"We'll be back later in the week and try it again," California visitor Alex Medel said.
"We'll have some heavy equipment in here and they'll get all the repair done," Hong said.
