The damaged dam at risk of failure in Puerto Rico continues to hold, and evacuees have begun to return to their homes. The dam on Lake Guajataca remains compromised, however, and a flash flood warning was still in effect Sunday. Aid is beginning to arrive to the "apocalyptic" island territory decimated by Hurricane Maria. Most Puerto Ricans remain without power, and 95 percent of cell phone service sites are down. Currently a Category 2 storm, Maria is expected to dissipate over the Atlantic Ocean later this week.
