Hurricane Maria ravaged Puerto Rico, leaving 100 percent of the island without power. The hurricane was a Category 4 storm with winds of 155 miles per hour when it made landfall on the U.S. territory Sept. 20.
Lopez is one of many artists, including Ricky Martin and Luis Fonsi, who have posted about how much help the island needs since the storm.
