Puerto Rico is experiencing a complete power blackout as a result of Hurricane Fiona, which continues to strengthen and is hitting the island with maximum winds of up to 85 mph.

The entire island is without power because of "transmission grid failures caused by Hurricane Fiona," according to power outage tracking website poweroutage.us.

According to the website, the outage is impacting 1,468,223 customers in Puerto Rico because of the Category 1 hurricane.

In a message posted to social media, LUMA Puerto Rico, the island's energy provider, said that its electrical system has experienced "several transmission line outages" which have "contributed to an island-wide blackout."
