As Hurricane Fiona makes its way toward Bermuda, it has intensified to a Category 4 storm and has already left a trail of damage on some of the Caribbean islands. Puerto Rico, which saw the storm’s landfall on Sunday, experienced massive power and water outages.

The Jet Aviation FBO at San Juan Luis Munoz Marin International Airport reported relying on its generators on Sunday and Monday before returning to grid power this morning. The location, which endured 60-mph winds, emerged with only minor water leaks in its roof and is drawing from its own reserve water tanks as it supports arriving humanitarian flights.

At the city's Fernando Luis Ribas Dominicci Airport also known as Isla Grande, Modern Aviation-which operates the lone FBO on the field-noted that it had no material damage to its facilities other than a few minor water leaks.

On Turks and Caicos, all airports were closed by authorities ahead of the storm yesterday morning. Much of the island lost power last night but electricity was restored this morning to Providenciales International Airport (MBPV), according to Provo Air Center, which told AIN it suffered no damage or flooding to its FBO. While MBPV saw little impact from Fiona, the country’s other airports—Grand Turk and South Caicos—were battered by high winds, with the latter closed entirely and the former open only to relief and medevac flights.

The U.S. Virgin Islands were spared the brunt of Fiona’s fury. Standard Aviation at St. Thomas Cyril E. King International Airport reported no damage, as did Bohlke International Airways at St. Croix Henry E. Rohlsen Airport.
