Four days after a major hurricane battered Puerto Rico, leaving the entire island in a communications and power blackout, regions outside San Juan remained disconnected from the rest of the island — and the world. Juncos, in a mountainous region southeast of the capital that was slammed with Maria’s most powerful winds, remains isolated, alone, afraid.

For many residents, the challenge of accessing the essentials of modern life — gasoline, cash, food, water — began to sink in. And government officials had no answers for them. Estimates for the return of electricity and basic services will be measured not in days but in weeks and months. For those most vulnerable, far too long.

Many have been openly wondering when help will arrive, whether from local officials or from the federal government. The first thing some villagers ask when they see outsiders: “Are you FEMA?”

Puerto Rico Gov. Ricardo Rosselló is warning that his government needs broader assistance from the federal government, calling on the Pentagon especially to provide more aid for law enforcement and transportation. Rosselló said he’s also worried that Congress will shortchange his island once the initial wave of emergency relief is gone.

“We still need some more help. This is clearly a critical disaster in Puerto Rico,” he said Sunday night. “It can’t be minimized and we can’t start overlooking us now that the storm passed, because the danger lurks.”
