Take care to break Puerto Rico dam

The inhabitants in the Rio Guajataca River in the northwest of Puerto Rico still can not return to their homes.

If that happens, it leads to catastrophic floods. 'We have inspected the dam and see how bad the damage is,' said Governor Ricardo Rossello via Twitter.

About 70,000 residents in the Isabela and Quebradillas region are advised to go to higher places on Friday, but not everyone has heard that. The authorities urged the backers to leave.

Puerto Rico has been severely affected by Hurricane Maria. The official death toll is 10, and billions of dollars have been damaged.
