A 58-year-old woman died of a heart attack early Friday after St. Lucie County suspended emergency services, marking the first reported death from Hurricane Matthew on the Treasure Coast, according to the TC Palm newspaper.

The woman, whose name has not yet been released, did not live on Hutchinson Island, which was under a mandatory evacuation, fire district spokeswoman Brenda Stokes said.

The death is considered storm-related because the fire district was unable to respond because of high winds associated with Hurricane Matthew, Stokes said.
