In pictures: Hurricane Maria pummels Puerto Rico

Puerto Rico has been devastated by Hurricane Maria, a powerful Category 4 storm that also impacted several islands in the Caribbean.

It was the strongest storm to make landfall in Puerto Rico in 85 years. It came ashore on September 20 with sustained winds of 155 mph, knocking out power to the entire island. Trees were uprooted, homes were destroyed, and there was also widespread flooding.

“This is total devastation,” said Carlos Mercader, a spokesman for Puerto Rico’s governor. “Puerto Rico, in terms of the infrastructure, will not be the same. … This is something of historic proportions.”
