Hurricane Maria knocks out power to all of Puerto Rico

SAN JUAN, Puerto Rico — Hurricane Maria delivered a destructive full-body blow to this U.S. territory on Wednesday, ripping off metal roofs, generating terrifying and potentially lethal flash floods, knocking out 100 percent of the island's electrical grid and decimating some communities. With sustained winds of 155 mph at landfall — a strong Category 4 storm and nearly a Category 5 — Maria was so powerful that it disabled radar, weather stations and cell towers across Puerto Rico, leaving an information vacuum in which officials could only speculate about property damage, injuries or deaths. Maria is the strongest hurricane to hit Puerto Rico since 1932.
