MIAMI (AP) -- The Florida Highway Patrol escorted gasoline trucks to dry fuel pumps and officials ordered thousands of metropolitan Miami's 6 million residents to leave Thursday as Hurricane Irma barreled toward a rendezvous with the state this weekend.
The National Hurricane Center issued a hurricane watch for the Florida Keys and parts of South Florida, the first of what is likely many watches and warnings throughout Florida over the next few days. While people in the state anxiously watched the behemoth storm, Irma battered the northern Caribbean, killing at least six people and leaving thousands homeless after destroying buildings and uprooting trees.
At least 31,000 people fled the Florida Keys, which could begin seeing wind and rain from Irma as early as Friday night, Gov. Rick Scott said. He noted the size of the powerful Category 5 storm, and told residents not to become complacent.
"It is wider than our entire state and could cause major and life-threatening impacts from coast to coast. Regardless of which coast you live on, be prepared to evacuate," Scott said.
The Republican governor acknowledged that traffic jams and gas shortages were "frustrating," and said federal authorities and other states were helping to move more gas into the state. He urged gas stations to stay open as long as possible to accommodate evacuees.
In the Keys, officials evacuated a hospital and expected to empty others along the chain of islands by the end of the day. Boats were tied down or taken out of the water. American Airlines, which has a hub in Miami, said its last commercial flight out of that city would be Friday.
Irma is the most powerful hurricane ever recorded in the Atlantic. The U.S. National Hurricane Center said it could rake the entire length of Florida's east coast and push into Georgia and the Carolinas, where governors had declared states of emergency.
Florida's governor waived tolls on all highways and told people if they were thinking about leaving to "get out now." He warned that Irma is "bigger, faster and stronger" than Hurricane Andrew, the last Category 5 storm to hit the state.
Andrew struck just south of Miami in 1992 with winds topping 165 mph (265 kph), killing 65 people and inflicting $26 billion in damage. It was at the time the most expensive natural disaster in U.S. history.
Mayors in Miami-Dade and Broward counties issued mandatory evacuation orders for barrier islands and low-lying mainland areas. But because of the uncertainty in the forecast, state and local authorities in Miami and Fort Lauderdale held off for the time being on ordering any widespread evacuations there.
President Donald Trump urged people to "be careful, be safe" during Hurricane Irma.
In a tweet Thursday morning, Trump remarked that Irma "is raging but we have great teams of talented and brave people already in place and ready to help."
Trump's exclusive Mar-a-Lago resort in Palm Beach - the unofficial Southern White House - sits in the path of the storm.
