Around a third of Puerto Ricans are still without power more than a week after Hurricane Fiona struck the island, with the U.S. now bracing as a separate storm heads to Florida.

The islands power operator, Luma Energy, said about 33% of homes and businesses, or about 490,000 customers, were without electricity as of 8 a.m. Tuesday morning. Thousands of others remain without access to running water, and officials have warned that the initial recovery effort could take weeks.

Those figures are down from the nearly 1.5 million Puerto Ricans who didnt have power Saturday, but they still present a major hurdle nine days after the storm hit the island. At least three people have died, although Puerto Ricos governor said as many as 16 deaths may be linked to the storm.

President Joe Biden has faced mounting pressure to issue a federal waiver so that a BP ship carrying diesel can access a port on the island to help alleviate the power crisis. The White House, however, says its hands are tied by a provision known as the Jones Act that imposes federal shipping restrictions.
