A terrifying torrent of water swept through Puerto Rico after a dam failed at Lake Guajataca in the northwest region.
Water was seen sweeping through the municipalities of Isabela and Quebradillas after the dam sustained structural damage from Hurricane Maria.
Nearly 16 inches of rain fell in the area, significantly raising water levels on the 90-year-old dam.
Earlier, Puerto Rican authorities had scrambled to evacuate as many as 70,000 people after the National Weather Service warned that failure of the dam was 'imminent' and could lead to 'life-threatening' flash flooding.
