The airport in Puerto Rico is full of people trying to get out, now one week after Hurricane Maria devastated the island. The territory's governor is now warning that Puerto Ricans might migrate en masse to the United States mainland.

"If conditions are inhospitable, if we don't have the resources to rebuilding properly, this is going to cause a problem for Puerto Rico, but of course, it's going to cause a problem for the mainland as well," Governor Ricardo Rossello told NBC News.

It's an issue thousands of people in Rochester are keeping a close eye on. According to U.S. Census data, there were an estimated 28,261 Puerto Ricans living in the city in 2015. That represents more than 13 percent of Rochester's population.
