Since the start of 2017, there have been 13 named Atlantic storms, making this year's hurricane season unusually active. In just the past four weeks, three major hurricanes ravaged the Caribbean and the United States Gulf Coast.

First came Harvey, which killed approximately 83 people, destroyed or damaged over 100,000 homes, flooded neighborhoods, and displaced over 30,000 in Texas and Louisiana. Then Irma hit Florida and several Caribbean islands, knocking out power, leaving thousands homeless, and killing at least 41 people.

Maria followed, ripping through Puerto Rico and Dominica and killing at least 17 people. The Category 3 storm, which was approaching the Turks and Caicos islands on Friday, has brought torrential downpours and powerful winds that have uprooted trees, demolished homes, and inundated roads on several Caribbean islands.

In Puerto Rico, tens of thousands of people started evacuating the island Saturday morning, after a failed dam cascaded floodwater throughout city streets and knocked out 85% of phone and internet cables. The Associated Press reports that dozens of mayors are arriving to meet with the Puerto Rico's governor, as officials plead for supplies.
