Hurricane Maria caused widespread damage to Puerto Rico. Drone footage captured the scene in San Juan and Canóvanas on Sept. 21.
As we reported earlier, flash flooding caused by the storm has prompted the NWS to warn that a dam in the northwestern part of the island is in danger of failing, prompting the government to scramble to evacuate the 70,000 residents of the river valley beneath the dam that is in danger of being completely submerged.
