Organizers for the "Kokua For The Philippines" benefit had hoped for sunny skies, but it was not to be.
The live TV broadcast was canceled, but entertainers and donors found a way for the show to go on.
The storm caused a safety hazard, so event workers had to pack up.
"We said we were going to brave the storm. We checked the front desk they said rain or shine that the concert was going on, so we got dressed and came on down," said Lauryl Joyce, a visitor from Michigan.
But the rain shut the public show outside. The concert portion of the Kokua for the Philippines fundraiser was called off. Some performers said the force of the rain was a reminder of the struggles those in the Philippines faced.
"This is all about reminding people of the onward going situation in the Philippines and in a way someone spoke upstairs and reminded us," said Mike Fleetwood of Fleetwood Mac.
"Mick came all the way from Maui and a lot of entertainers came all the way from Maui. A lot of workers were here and everybody was here to support," said musician Henry Kapono.
The show and support for the Philippines continued. More than thirty entertainers, local singers and artists shifted their efforts indoors. The phone bank and an impromptu performance was streamed live on the web.
Artist Robert Wyland painted, local musicians performed and some "Hawaii Five-0" cast members picked up calls continuing the fundraising.
"Philippines has really been suffering. Some people thought the worse is over but no now is when the real work needs to happen," said Mayor Kirk Caldwell.
The event has raised more than $1.7 million in pledges and donations.
