With hurricane season starting June 1, CNN returns to Puerto Rico to see if the island is ready for another storm. Nine months after Maria, 20,000 homes are still without power- and going into the season, many mayors are worried that even a small storm will plunge them back into darkness and repeat the crisis all over again. We witness desperate Puerto Ricans illegally and dangerously turning on their own power, and press officials for answers on what will change this time around.

(CNN) —

Much more work must be done to meet Puerto Rico’s critical humanitarian needs after Hurricane Maria, the US territory’s top official said Saturday, while also emphasizing that the federal government is fulfilling his every request – striking a conciliatory tone minutes after President Donald Trump lambasted a mayor who criticized Washington’s response.

“We need to do a lot more in order for us to get out of the emergency,” Puerto Rico Gov. Ricardo Rosselló said in San Juan. “But the other thing that’s also true is that the administration has answered and has complied with our petitions in an expedited manner.”

Eleven days after Hurricane Maria began to pound Puerto Rico as a Category 4 storm, millions in the US commonwealth remain without regular electricity service, and many have limited access to gas, cash and running water. At least 16 people died there as a result of the storm, the government has said.

Earlier Saturday, Trump – who plans to visit the island Tuesday – used Twitter to criticize San Juan Mayor Carmen Yulín Cruz and the “leadership ability” of some in Puerto Rico who “want everything to be done for them when it should be a community effort.” Yulín Cruz earlier had criticized the distribution of aid and said the feds needed to do more.
