Most of Puerto Rico remains without power, a day after Hurricane Fiona brought 100-mile-an-hour winds and up to 30 inches of rain to parts of the island. On Sunday, Puerto Rico’s entire electrical grid collapsed as Fiona’s eye roared across the island’s southwestern coast, triggering flash floods and landslides and washing away at least one major bridge. Governor Pedro Pierluisi described the damage as “catastrophic.” Fiona hit just two days before the fifth anniversary of Hurricane Maria, which killed thousands of people and devastated Puerto Rico’s electrical grid and other infrastructure.
