Hurricane Maria left Puerto Rico in ruins, with mass power outages and nearly half the residents without drinking water.
Barea reportedly left Monday after communicating with his parents for the first time Sunday and learning where help was most needed.

Barea, the only active native Puerto Rican in the National Basketball Association, said on Wednesday the island is in bad shape (via ESPN's Tim MacMahon).
"I texted him. Five minutes later, he goes, "Check your email, '" said Barea, who spent about four hours in Puerto Rico, helping unpack supplies that included medicine and 32 generators". In response, Cuban said he was "really proud" of Barea for how quickly he got involved. "He's going to take his mom and grandmother back with him, and my understanding is his dad is going to stay over there and slug it out with all of the recovery efforts".
Barea hopes the publicity from his trip, as well as the fundraising efforts of Carmelo Anthony and several Puerto Rican-born baseball players, will raise awareness of the problems facing Puerto Rico, most of which is expected to be without power for several months.
