Winehouse spokesman Chris Goodman said in a statement Saturday that the singer abandoned her performance Friday at the St. Lucia Jazz Festival.
He says heavy rain pounded the stage on the Caribbean island, causing a lighting rig to fail and disrupting sound equipment.
The gig was the troubled British singer's first performance of 2009.
Goodman says that Winehouse attempted to continue her performance despite the storm, but was forced to stop.
He says the singer was disappointed, as she'd hoped to repay people in St. Lucia for their hospitality.
Winehouse has been staying on the island for several months.
