TOPSHOT - Cars drive through a flooded road in the aftermath of Hurricane Maria in San Juan, Puerto Rico, on September 21, 2017. Puerto Rico braced for potentially calamitous flash flooding after being pummeled by Hurricane Maria which devastated the island and knocked out the entire electricity grid. The hurricane, which Puerto Rico Governor Ricardo Rossello called "the most devastating storm in a century," had battered the island of 3.4 million people after roaring ashore early Wednesday with deadly winds and heavy rain.
