Aid supplies to Puerto Rico are trapped at a port in the capital, San Juan, according to reports on Thursday.
They’re trapped because there’s a shortage of truckers, trucks, and devastated infrastructure after Hurricane Maria hit the island.
Only 20 percent of truck drivers in the U.S. commonwealth have reported back to work, said a representative for Puerto Rican Gov. Ricardo Rosselló. There’s also a diesel fuel shortage and a number of roads that have been blocked by floods and other hurricane-created damages.
Contacting drivers is an issue due to downed cell towers.
"When we say we that we don't have truck drivers, we mean that we have not been able to contact them," Rosselló told the network.
On Thursday, the White House authorized 10-day waiver of the Jones Act, which is a federal law that limits shipping to U.S. ports by foreign vessels.
Ayala said that only about 4 percent of containers that were sent to San Juan’s port have been dispatched from there
"The problem has been with the logistics, the parts of the supply chain that move the cargo from our terminal to the shelves or to the tables of the people in Puerto Rico," Ayala said on Wednesday. "This hurricane was catastrophic."
White House spokeswoman Sarah Sanders told Reuters that 10,000 federal government relief workers were now in Puerto Rico, including 7,200 troops, and that 44 of the island’s 69 hospitals were now fully operational.
Overall, the island is likely to need far more than $30 billion in long-term aid from the U.S. government for disaster relief and rebuilding efforts following Maria, a senior Republican congressional aide said on Thursday.
The Department of Defense said it will aid FEMA's efforts to stabilize the situation on the island.
"Gasoline is beginning to flow to gas stations, which, despite rationing, are unable to remain open for more than a few hours at a time," according to the Pentagon.
