Hurricane Maria devastated Puerto Rico and cut power to the entire island - here's what it looks like on the ground

Hurricane Maria slammed into Puerto Rico at 6:15 a.m. on Wednesday as the third-strongest hurricane to ever hit the US.

The direct hit caused widespread destruction.

"The San Juan that we knew yesterday is no longer here," San Juan Mayor Carmen Yulín Cruz told MSNBC on Wednesday night. The mayor said Puerto Rico, home to some 3.5 million people, is "looking at four to six months without electricity."

Rescue attempts are ongoing and it'll be some time before the full scope of the damage is known, but some early images have begun to emerge.
