On Sunday afternoon, an islandwide blackout was reported as the eye of Fiona neared Puerto Rico's southwestern coast. Hurricane Maria devastated Puerto Rico on Sept. 20, 2017. In the meantime, residents were getting ready for another tropical storm, albeit one less destructive than Hurricane Maria.
